Problems in the definition of second position include notions of skipping, the identity of the first element, & host suitability. Debate over syntactic, prosodic, & combined syntactic & prosodic derivations of second position is examined; it is suggested that prosodic sensitivity may be allowed, not required, for clitic placement by universal grammar. Relations between second & later clitic positions & between classes of clitics eligible for each position are explored; clitic clustering & subject clitics are also discussed, & possible independent motivations for the special syntactic nature of clitics are addressed. 17 References.

When many different crystalline phases are present, quantitative analysis is better constrained if used in conjunction with a determination of bulk elemental composition, obtainable by X-ray fluorescence (XRF) using the same X-ray source as for XRD. A combined XRD-XRF instrument should allow one to fully characterize the mineralogical composition of a complex unknown material. For planetary surface analysis, a remote instrument combining XRD and XRF could be used for mineralogical characterization of both soils and rocks. We are designing a remote XRD/XRF instrument with these specific objectives in mind. The instrument concept pays specific attention to constraints in sample preparation, weight, volume, power, etc. Based on the geometry of a pinhole camera (transmission geometry, flat two-dimensional detector perpendicular to the direct beam), the instrument (which we call CHEMIN, for Chemistry and Mineralogy) uses an X-ray sensitive CCD detector which will allow concurrent positional and energy-dispersive analysis of photons collected during analysis. Thus XRF (energy) and XRD (geometry) analysis of transmitted X-rays will be performed at the same time. In its "Mars soil analysis" version, the instrument may be based on either a lander or rover. Thin, sticky substrates dragged through the soil allow the simplest sample collection. Tests performed with single minerals give promising results and show both the power and the limitations of the technique. Refinements of the prototype promise interpretable results on complex samples.

Distributions of trace elements such as Zr, Hf, Th, U, and REEs in the UBT are dependent on the crystallization of accessory minerals such as zircon, chevkinite, apatite, and monazite. We studied zoned zircons and host pumice compositions to better understand the origin of trace element zonation and the chemical evolution of the Valles magmatic system. BSE images reveal textural characteristics such as truncation and resorption in some zircons from each UBT cooling unit. EMP traverses across cores of many zircons reveal values of 0.5 and 0.3 wt.% U and Th oxide respectively, while rim values approach greater than or equal to 0.1 wt.% U and Th oxide. EMP concentrations across unzoned zircon gave values similar to the rim values of zoned zircons. SIMS analysis gave U and Th values up to 4600 and 1640 ppm, respectively, in core regions. Pumice and glass show systematic increases of these elements toward the basal plinian fall unit, indicating an increase of these elements toward the top of the UBT magma chamber. Several magmatic processes could explain the complexity of zircon crystallization. We find fractionation and recycling of zircons from ancestral Bandelier magmas (greater than or equal to 1.5 Ma) consistent with the zircon and magma zoning, however further work is needed to fully refute or verify any of the proposed models.

Scientific results are used to set policy and to make decisions that can affect our health and well-being, and scientists have an obligation to provide the technical support necessary to make informed decisions on environmental issues. The non-scientific portions of environmental issues can raise an interesting dilemma for scientists: often a decision requires a definitive opinion on an issue that is not scientifically clear-cut. In other words, one is forced to become an advocate for a position which an objective scientist might consider equivocal. The consequences of this dilemma are well illustrated by the issue of inhaled minerals and health. "Is asbestos (or silica, or erionite, ...) carcinogenic?" is a question that has been the focus of extensive scientific research and that has been answered with countless (often contradictory) scientific opinions. For example, recent scientific opinion on "Does chrysotile pose a risk of mesothelioma (a rare asbestos-related cancer) in humans?" may have shifted towards "Probably not in most cases". However, this opinion is not shared universally among scientists, and compelling scientific arguments can be offered in support of either position. Which is the scientifically correct position? There is a wide range of mineralogical research that is required for issues related to the health effects of minerals. Important mineralogical research includes the dissolution characteristics of minerals and other materials, background (natural) sources of mineral dusts, and an identification of the mineralogical properties important in mineral toxicity/carcinogenicity. Research on this latter topic, in particular, has the potential to improve our understanding of the mechanisms of mineral-induced diseases.

Proper management requires understanding fluxes of water, sediment, and energy. Surface runoff represents a major mechanism which redistributes water, sediment, nutrients and contaminants in these woodlands. The objectives of this study are to better understand fluxes of water and sediment at small scales and to understand the influence of vegetation cover on these fluxes.In summer 1994, we installed three sets of runoff plots (1-8 m long) on a pinyon-juniper hillslope in north-central New Mexico. The plots are designed to quantify runoff and erosion dynamics as influenced by ground cover. Following naturally occurring precipitation events, we measure the volume and sediment concentration of runoff. During two years runoff occurred 65 times. The 1-3 m long, sparse ground cover plots, yielded over 250 mm of runoff and 1600 g/m (super 2) of sediment. In contrast, the same sized plots with dense ground cover yielded only 150 mm of runoff and 200 g/m (super 2) of sediment. These sequential 1-3 m long plots are paired with 8 m long plots that encompass patches of sparse ground cover (upslope) and dense ground cover (downslope). The 8 m long plots yielded 150 mm of runoff and 500 g/m (super 2) of sediment. The total runoff and sediment yield from the 8 m long plots is less than the 1-3 m sparse cover plots implying that water and sediment are stored within the 8 m long plots. These data demonstrate at small scales, patches of sparse ground cover frequently generate water and sediment that is redistributed to patches of dense ground cover. This additional flux may be critical to sustaining these dense patches of ground cover.

Fracture permeability is extremely difficult to measure in the lab or the field, and is, instead, typically estimated by assuming a "parallel plate" behavior--where fracture permeability is proportional to the average aperture cubed. However, there has been little quantitative analysis of the accuracy of this assumption. The lattice Boltzmann (LB) computational method provides a high resolution, highly accurate tool to study fracture flow and transport. At Los Alamos, we have developed a powerful LB 3-D multiphase flow in porous media computational model. The accuracy of this model in predicting permeability in porous media has been shown to be quite good (typically within 10%) [Soll et al., 1994]. Using the LANL LB model, we can directly compute permeability in a real fracture using high-resolution digital images. These images also provide aperture statistics. We have high-resolution digital images of three different Tuff fractures which have been converted for use in the LANL LB multiphase flow code. Using subsets of the full fracture data, we computed permeabilities for nine different fracture spaces. We then compared the simulation results to values predicted by the parallel plate (cubic law) assumption. Agreement between the two values varied, with the cubic law value ranging from 90% to 125% of the simulated value, biased toward the high side. Evaluation of chemical, multiphase, and biological transport and reaction processes are within the developing capabilities of our approach, and will be pursued following hydrologic characterization.

An accurate, cost-effective characterization of the extent of contamination poses special challenges due to the wide dispersal and the extended time periods since releases. The use of a Geographic Information System (GIS), is a key component of our strategy to rapidly evaluate the extent of contamination, to base decisions on optimizing sample locations, to analyze spatial variations in contaminant concentration, and to provide a permanent archive for future investigations. Topographic maps with 2-ft contour intervals (using a Digital Elevation Model with a 4-ft grid, generated from 1991 air photos), provide the base for geomorphic maps of detailed study reaches. Data from gross gamma radiation walkover surveys, acquired at one or two second intervals and geo-referenced utilizing either Global Positioning System (GPS) receivers or a local radio telemetry base (USRADS system), are downloaded into the GIS at the end of each day's survey, made into a point coverage, and overlain on the geomorphic map. Large data sets (up to 13,900 gamma measurements daily), can be viewed spatially in a matter of hours, optimizing subsequent surveying, field measurements, and sample collection. Use of a GIS allows rapid revision of the geomorphic maps and analysis of the data by geomorphic units, and also provides a permanent electronic archive accessible by earth scientists, risk assessment personnel, environmental surveillance groups, and outside regulatory agencies.

Quantitative XRD and XRF results can be combined using quadratic goal programming to improve the precision and accuracy of both. Anomalous XRF or XRD data may be resolved by cross-comparison, providing constraints where otherwise questions would remain. To realize this goal, several technical challenges must be overcome. Mechanically, the instrument must be simple yet capable of positioning samples; designs for sample collection and introduction are many and several configurations are possible. The sample-mounting medium should not interfere with light-element XRF analysis (especially C); several C-free substrates satisfy this limitation. Whether isotopic or small tube, the X-ray source will be weak and improved collimators will be required to provide the needed flux at the sample. The instrument should be able to measure low-angle diffraction (to <6 degrees with a Cu source) if clay minerals are to be analyzed; this need can be satisfied by coupling a small beam stop with the focusing collimator. Aside from these hardware challenges, there are advances underway in XRD data handling that are important for success. Among these are the analysis of non-Bragg diffraction from clay minerals and of the scattering from amorphous materials. These challenges are not insurmountable and the resulting integration of XRD, XRF, and data reduction will provide a powerful new analytical tool.

Interestingly, sorption of simple cationic radionuclides is only of minor significance, due to (1) short half-lives of most of these radionuclides; and (2) generally high sorption coefficients of many common minerals for such species. The most important radionuclide migration issues concern anionic species (e.g., Tc and I) and actinides (e.g., Np and Pu) that often form large, complex aqueous species. Few, if any, minerals at Yucca Mountain interact significantly with anionic species. However, minor and trace minerals, such as smectite and Fe and Mn oxides and hydroxides are important in retarding the migration of complex actinide species such as neptunyl. Emplacement of high-level radioactive waste will also heat large volumes of rock. The potential repository horizon at Yucca Mountain is in the vadose zone, and zeolites and smectite will be important sources and sinks of water and thermal energy during dehydration/rehydration. These sources and sinks must be considered when modeling the long-term thermohydrologic behavior of Yucca Mountain. Mineral reactions such as clinoptilolite-to-analcime may also be important if temperatures are sufficiently high. Recent studies show the utility of minerals as recorders of past aqueous transport. For example, even thin layers of zeolitic tuff record the retardation of Sr, and fracture-lining minerals record retardation of Ce. No matter what the repository site, mineralogy is of considerable importance both in understanding past conditions and in predicting future high-level waste repository effects.

The apparent coincidence of these high ratios with mapped faults suggests that fault-induced fracturing may provide a fast path between the surface and the ESF. To explore the nature of these fast paths, we have conducted a series of numerical simulations of vadose-zone flow and transport using LANL's Finite Element Heat and Mass (FEHM) code. A key FEHM feature is its dual-porosity/dual permeability capability, in which the rock matrix and fracture network are modeled as separate but overlapping and interacting continua. We simulated flow and chlorine-36 transport along vertical columns intersecting the ESF. Initial base-case simulations, using a range of reasonable recharge rates and hydraulic parameters, showed that no solutes could reach the ESF within 50 years, because rapid fracture flow cannot be maintained through one of the overlying units, the nonwelded Paintbrush tuff (PTn). This result is consistent with the lack of bomb-pulse chlorine-36 at most locations in the ESF. Modification of the hydraulic properties of the PTn fracture network consistent with fault-induced fracturing permits sustained fracture flow through the unit, and arrival of bomb-pulse chlorine-36 at the ESF within 50 years. The required changes include elevated fracture density and/or aperture, consistent with increased fracturing or faulting associated with major tectonic features. These results are consistent with a conceptual model in which undisturbed PTn inhibits rapid vertical transport, while areas with increased fracturing permit some rapid movement.

We have inverted 4872 P-wave arrival times from 216 earthquakes recorded on a network of 50 stations in and around Valles caldera to produce a detailed picture of velocity structure to depths of 37 km. To invert the data, we employ an iterative least-squares approach, using 3-D ray tracing through an interpolated grid with 3 km node spacing. Velocity perturbations from a background model are determined for seven layers, including one at 2.0 km depth below surface designed to handle strong near-surface velocity variations. Arrival time residuals are reduced through inversion by roughly 85%. The principal features of our model are a distinct shallow low velocity zone beneath the Toledo Embayment, an intense low velocity zone in the mid-crust at 12 km, where velocities are reduced by 25-30% from background, and a lower-crust or upper-mantle low velocity zone at about 37 km having a velocity reduction of 15%. To interpret our velocity image, we compare our results to velocity values taken from compilations of active rifts and extensional regimes. Upper crustal velocities are fairly well known in these environments, ranging from 6.0 km/s in the Rio Grande Rift to 6.2 km/s elsewhere. A reduction of 25-30% from these values can only be explained by the presence of melt. We interpret this partially molten mid-crustal zone as the residual magma chamber of the caldera-forming eruptions. From a similar analysis of lower crust and upper mantle velocities, we find that either gabbro or basaltic melt is present at 37 km, depending on how thick the crust is in this region. In either case, we interpret this anomaly to show ponding of basalts at or near the base of the crust.

However, researchers have argued that the Silurian-Ordovician rocks played no part in the mineralization process.We have compared the isotopic signatures of the deposits with those of the underlying Silurian-Ordovician rocks to determine whether Silurian-Ordovician-circulated fluids are involved in the mineralization process. Carbon and oxygen isotope data from unmineralized carbonate hostrocks (delta O: 22.2 to 28.1 per mil, delta C: 2.4 to 4.1 per mil), mineralized hostrocks (delta O: 17.6 to 27.1 per mil, delta C: 1.5 to 4 per mil), orestage carbonates (delta O: 17.1 to 26.9 per mil, delta C: -2.8 to 3.4 per mil), orestage carbonate veining (delta O: 16.7 to 26.5 per mil, delta C: -4.6 to 3.2 per mil) and post-orestage carbonate veining (delta O: 15.9 to 25.8 per mil, delta C: -4 to 2.6 per mil) document an evolving hydrothermal system in which fluids became isotopically lighter. Preliminary strontium isotope work reveals that the lighter fluid(s) have a higher 87Sr/86Sr ratio than the heavier fluids. The isotopic composition of hydrothermal carbonates becomes lighter as major faults are approached, and there is a regional trend toward lighter carbon and oxygen isotope values with proximity to the Silurian-Ordovician rocks. New isotopic data from hydrothermal carbonate minerals in Ordovician-hosted veins near the Tynagh deposit (delta O: 14.5 to 20 per mil, delta C: -11.2 to -5.9 per mil) and from Silurian-hosted veins near the Navan-Tatestown deposits (delta O: 19.7 to 23.5 per mil, delta C: -8.8 to -7.5 per mil) are best interpreted as representing an endmember to the regional and local isotopic patterns. This fact suggests that major faults associated with mineralization were conduits for an isotopically lighter, radiogenic fluid originating from fluids circulating within the Silurian-Ordovician rocks. Quantitative modeling of the carbon and oxygen isotope data indicates that the isotopic systematics of the deposits is best explained by a combination of fluid-hostrock-exchange and fluid-mixing between a Silurian-Ordovician-circulated, isotopically lighter, high temperature, low salinity fluid and a local, low temperate, isotopically heavier, high salinity fluid. This study, supported by numerous other lines of evidence, indicates that the Silurian-Ordovician rocks played an important role in the genesis of the Irish Pb-Zn deposits.

Vertical erosion on the Whaleback and Antler Ridges of Yucca Mountain is proceeding gradually, mostly through thin-layer (<4 cm) exfoliation, grusification, and dissolution as represented by residual spalls and well-developed gnammas and rillen. The mean MAXIMUM BEDROCK erosion rate is 0.13+ or -0.10 cm/kyr (std. dev. = 0.08 cm/kyr; n = 11). The patchy preservation of rock varnish on the sampled surfaces concurs that although erosion is occurring, the rate has been very slow. The calculation assumes that erosion was effectively constant, that the age of the surface was infinite, and that the Be-10 concentration was controlled by erosion. The erosion of unconsolidated material (colluvium and regolith) on the middle and lower flanks of Yucca Mountain is similarly slow and mainly through channel incision. Four relict boulder deposits on Yucca Mountain and nearby hillslopes have a median age of 490 kyr (n = 13). Age range for the deposit on the west side of Yucca Mountain: 310 to 2950 kyr; east side of Yucca Mountain: 130 to 490 kyr; Buckboard Mesa: 535 to 585 kyr; and Little Skull Mountain Pass: 390 to 1100 kyr. Using the youngest boulder age and a maximum of ca. 1 m of average slope denudation on Yucca Mountain, the MAXIMUM HILLSLOPE erosion rate is approximately 0.8+ or -0.3 cm/kyr. Horizontal cliff retreat of the tuffs has not been constant, but episodic, with block falls typically on the order of 30 to 100 cm thick. Cosmogenic nuclide ratios have not yet been measured, but considering the presence of patchy rock varnish preserved on the vertical cliff faces in re-entrants, the cliff retreat rate is also apparently slow.

The DOE requires a radiological Performance Assessment (PA) for continued operation of the site. The PA is an ongoing effort involving an interdisciplinary team whose goal is to understand the geology, hydrology, and geochemistry of the site in order to assess its long-term risk. Our involvement is to predict the transport of radionuclides from the disposal pits through the thick unsaturated zone (some 800 plus feet) downward to the water table. This talk will focus on the development of a flow model for the site and give results for transport calculations. Area G is located within a mesa top consisting of alternating sequences of fractured, volcanic tuff. The mesa top configuration and extremely low vadose-zone saturations (2% to 30%) make this area challenging to model. We have worked closely with geologists to capture the sloping, thinning tuff layers in order to predict flow patterns in two and three dimensions. In particular, we investigate a lateral flow path in a pu mice layer that is overlain by tuff and underlain by basalt. We also determine the uncertainty in calculated transport times due to uncertainty in hydrologic properties. An abundance of fractures within the mesa top leads to the question: Can fractures act as fast paths for contaminant migration during periods of high infiltration? We model the system using a single fracture model and a dual permeability model under transient conditions to answer this question. The studies indicate that fracture transport is unlikely to be a significant process.

Characterization data affect the probability term; the remaining terms relate only to cost. We provide an example determination of the failure probability, to demonstrate the approach. Groundwater beneath Los Alamos Canyon is contaminated with 3H, 137Cs, and 90Sr from at least two LANL facilities. Elevated levels occur in perched groundwater in alluvium overlying Bandelier Tuff downstream of Technical Area(TA)-2, where nuclear reactors operated (1943-1992), and below the confluence of DP Canyon, which drains TA- 21, where plutonium was processed (1945-1978). Calculations for 3H detected in perched, intermediate-depth ( approximately 300 feet) groundwater indicate travel times of approximately 22 years ( approximately 15 ft/year). An Excelo/Crystal Ballo spreadsheet model was run to evaluate 3H transport as a conservative tracer of contaminant movement in groundwater in and between shallow and intermediate-depth zones. The model incorporates release and decay of the 3H source from TA-2, travel through bedrock, and down-gradient plume spreading to estimate the amount released, volume of plume, and plume concentration of 3H. The model is sensitive to partitioning between alluvium and bedrock, and groundwater travel time, and suggests limited potential for significant deep contamination. The results suggest that characterization is unlikely to produce significant reduction in the probability of failure for this performance measure, and that upfront modeling may be a superior means to reduce uncertainties for similar more serious concerns. A variety of codes are being used to model the transient characteristics of the alluvial perched groundwater and to evaluate contaminant partitioning among transport pathways in alluvial and intermediate-depth zones. These may provide insights for various contaminants in Los Alamos Canyon.

Present focus is on the unsaturated zone (UZ) and particularly in understanding and predicting radionuclide transport in the UZ. Surrogate elements can be used to infer transport processes (e.g., lanthanides as analogs for actinides), but explicit results can be obtained for elements such as Sr that are common constituents of radioactive wastes. Although transport of radioactive Sr is not a concern at Yucca Mountain, patterns of past Sr migration can be used to verify transport concepts and to map the natural transport system. Profiles of Sr distribution within the UZ can be compared with mineralogy to evaluate the cumulative retardation of Sr movement by zeolitized tuffs. Retention of Sr is correlated with the tops of stacked zeolitized horizons. Zeolitized horizons with as little as 2-3% clinoptilolite apparently have provided effective retardation of Sr transport. Sorption/desorption and dispersion processes have allowed penetration of Sr retention profiles up to 30 m into zeolitized horizons where vertical transport in the UZ is inferred. In addition, trace-element compositions of fracture-lining calcites provide evidence of modification of groundwater lanthanide-element compositions over flow paths of <50 m. The mineralogic and geochemical data indicate that important interactions of some radionuclides with host rocks at Yucca Mountain will occur on distance scales of a few tens of meters, within small portions of the total transport distance of several kilometers from the potential repository to regulated areas of concern.

We are investigating the patterns of metamorphic textures produced in the crust during regional metamorphism by combining thermal models of metamorphism with simulations of metamorphic reaction mechanisms based on differential and irreversible thermodynamics. In this study, we have used a 3D integrated finite difference program (MOR3D, Travis et al. 1991: G. Res. Let. 18:1441-1444.) to investigate the transport of heat, fluid and dissolved species around mid-crustal intrusions that produce regional contact metamorphism similar to that found in western Maine. The results of the thermal calculations are output as a time-series of P-T data for each node in the volume of crust being modeled. The P-T data are then used as input for the Gibbs90 program (Spear et al. 1991: Am. Min. 76,. 2009), which uses differential thermodynamic techniques to calculate the mineral compositions, modes and whole-rock reaction at a node for each time step from the P-T data and the bulk composition of the rock present at the node. The sequence of whole-rock reactions is then used as input to the Seg93 program (Foster 1993: GSA Abs. 25, A264), which uses irreversible thermodynamics to calculate the reaction mechanisms and resulting mineral textures that develop at each node for each time step. The end result is an array of images that shows the type of rock texture expected for each time step at any node in the model. This method is advantageous in that it shows the spatial distribution of rock textures and mineral reactions produced by a specific thermal model, which can be readily compared to features observed in the field to assess the validity of proposed reaction mechanisms, fluid flow regimes or tectonic scenarios.

AN - 52701422; 1997-048518 AB - The soil-forming interval concept of Morrison (1978) assumes that paleosols in the Quaternary record formed only during interglacial or interstadial warm climates. Soil-landscapes are complex open systems, however, that respond to a variety of intrinsic and extrinsic forcing factors, not just warm temperatures. Geomorphic and pedologic subsystems may also respond independently of one another to extrinsic forcing; either enhancing or limiting soil genesis. Geomorphic and pedologic controls, therefore, must be evaluated independently and then jointly to the extent possible. Additionally, in many cases the connections among the environmental milieu, pedogenic processes, and resultant soil features are poorly understood. New studies from diverse soil-geomorphic systems, ranging from loess to alluvial fans, show that variations in landscape stability to erosion or deposition; vegetative cover; atmospheric fluxes of carbonates, salts, and clays; soil-water balance; etc. strongly influenced when soils actually formed within climatic cycles in different settings and what suite of soil features were formed. In loess of the northwestern U.S., the "best developed" paleosol over the last 100,000 yr. is the Washtucna Soil. Radiometric dating, tephra markers, and periglacial features demonstrate, however, that this soil formed during the cold phase of the late Wisconsin, principally because low rates of loess deposition and continued vegetative cover created a stable landsurface for pedogenesis. Examples such as the Washtucna Soil show that significant soils can form during any climatic phase depending on system controls; therefore, marker paleosols cannot be correlated correctly over long distances if they are assumed to be strictly interglacial climatostratigraphic units.

Aggradation reached its highest historic level in the late 1950s at the upstream end of the 2-km study reach, followed rapidly (<10 yr) by initial incision as aggradation continued downstream. A similar pattern of maximum aggradation followed by incision continued until the early 1980s as the intersection point migrated downstream. The peak of aggradation at each location was characterized by deposition of bedload sediment in lobes over older terrace deposits, recording highly episodic sediment transport. Incision throughout the reach had occurred by 1986, and was apparently dominated by channel bed erosion, although it is also affected locally by resistant bed material (cemented alluvium, large roots) that form temporary knickpoints. The historic aggradation presumably records the passage of a slug of sediment derived from accelerated erosion upstream, although we have not determined when aggradation began upstream or its cause. We expect that similarly variable transport and deposition of bedload sediment characterizes many streams in this region, and that other terraces in the area are also diachronous surfaces that record the passage of slugs of sediment.

Previous studies indicate that the stability of clinoptilolite is governed primarily by temperature and aqueous silica and sodium activity. There now exist adequate thermodynamic data for clinoptilolite and analcime to provide a basis for a semi-quantitative analysis of the stability of clinoptilolite. In this study, primary calorimetric data were extended by a modified thermodynamic estimation procedure and combined with recent cation-exchange (Pabalan 1994) and hydration (Carey and Bish 1996) studies to yield the thermodynamic properties of arbitrary compositions of clinoptilolite and analcime. The equilibrium breakdown of clinoptilolite to analcime was calculated assuming cation-exchange equilibrium with aqueous solutions of variable Na/Ca and Na/K ratio, as a function of temperature and silica activity. The results show that the strong affinity of clinoptilolite for K or Ca over Na limits the stability of analcime to silica-poor, Na-rich solutions. The clinoptilolite stability field is maximized for aluminous compositions in equilibrium with siliceous analcime. Temperature decreases the stability field of clinoptilolite, but this effect is moderated slightly by the loss of water from clinoptilolite. Estimates of uncertainty in these results were derived by comparison of predicted and measured calorimetric data for clinoptilolite and analcime. The uncertainties are significant with respect to the predicted stability field of clinoptilolite.

Analyses of samples collected at 52 locations in the ESF tunnel have been completed. The rocks analyzed include systematic samples collected every 200 m throughout the tunnel, as well as samples from diverse geologic features such as faults, fractures, and lithophysal cavities. All of the systematic samples as well as most of the feature-based samples contain Cl-36 levels consistent with travel times exceeding a few thousand years. Upper age limits for ground-water travel times are several hundred thousand years. Uncertainties about temporal variations in the atmospheric Cl-36/Cl input ratio prevent calculation of more precise ground-water travel times at present. Bomb-pulse Cl-36 (elevated ratios of Cl-36/Cl above 1500X10E-15) occurs at a few distinct fractured and/or faulted zones in the tunnel, indicating that at least a small proportion of the water at these locations is less than 50 years old. The location and distribution of these fast fluid pathways will help us better understand the hydrology in and around the proposed high level waste repository at Yucca Mountain. Bomb pulse Tc-99 has also been measured in one of the samples containing elevated Cl-36.

We are studying Be, Pb, B, La, and Nb in samples from either side of the QSC. Leeman et al. (1994, G.C.A., 58, 149) observed elevated 10Be ratios in samples from NW of the QSC, suggesting a greater subduction component to the NW. The story for the fluid-mobile elements (Pb, B) and the refractory lithophile elements (La, Nb), are quite different from the 10Be behavior, suggesting a decoupling of these 3 groups of geochemical tracers. La decreases from the NW to the QSC, and rises SE of the QSC. The relative enrichments of La SE of the QSC suggest either low degrees of partial melting or source enrichment. High lava volumes SE of the QSC, however, argue against low degrees of melting, and argue for the prior enrichment of La by metasomatism (hot-spot process?) in the mantle wedge. Pb is roughly correlated with B on each side of the QSC, and our larger data set for Pb suggests that Pb abundances are relatively constant across the QSC. Thus the constant B and Pb concentrations on both sides of the arc reflect a similar fluid-mobile element subduction component. The decoupling of 10Be from B may reflect differences in the fate of the uppermost sediments (10Be reservoir) on each side of the QSC, but not in the amount of bulk sediments (the B reservoir, and possibly the Pb reservoir) being subducted. In conclusion, 10Be is surprisingly the only tracer affected by the different subduction geometries across the QSC.

Streamlined modeling systems test various waste emplacement strategies, backfill material properties and groundwater infiltration rates allows rapid investigation of multiple designs. This study investigates radionuclide transport from waste packages inside a tunnel. The modeling domain contains six distinct material, rock matrix, an invert on the tunnel floor, two different waste packages, crushed rock backfill and air above the backfill. Model setup utilizes the X3D/Geomesh grid generation software for 3D finite element grid generation, optimization, smoothing and enhancement. Models have realistic 3D geometry and maintain sharp interfaces between the multiple materials. Hydrologic models are based on measured characteristic curves for unsaturated flow in the rock and proposed backfill and invert material. The radionuclide transport model uses the unsaturated diffusion coefficient curve and sorption coefficients measured in the laboratory to characterize transport through the backfill and invert material. Even in the absence of advective flux through the drift, radionuclides are predicted to travel by diffusion through the backfill material rapidly enough to allow them to escape in significant quantities over the time of regulatory interest (10ky-1 My). Sorption of Np-237 on an invert material such as apatite is shown to delay the escape of this important radionuclide from the drift region. The exact nature of the regulations, specifically the maximum time scale of interest, will decide whether this sorption results in a performance benefit sufficient to justify the added cost of utilizing a sorptive material.

The volcanic field has been the site of hydrothermal activity for much of its history including the present day Valles hydrothermal system. Surface and borehole sampling of this system has provided important constraints on the range and sequence of hydrothermal processes. Geologic evidence points to the former caldera lake systems in the moat region of the Valles caldera. These caldera lakes, especially at Sulphur Springs, had a profound effect on the dynamics of the hydrothermal system. The lakes permitted near surface fluid temperatures and pressures that were much higher than those possible for the present purely subaerial system. Increased solubility of both metals and gases are observed in fluid inclusion samples of past geothermal waters. Analysis of present day hydrothermal fluids and fluid inclusions indicate a clear magmatic signature with an average 3He/4He of 4.5 times the air value and elevated 40Ar, which may be derived from a magmatic source. Stable isotopes of carbon and sulfur also suggest a magmatic source component.

Lithic clasts show normal vertical and lateral grading in all four units. Pumice clasts show reverse vertical and lateral grading within three flow units; normal vertical and lateral grading of scoria clasts has been observed in one flow unit. The origin of vertical and lateral grading of lithic and pumice clasts is related to mechanisms operating during the transport process within the high particle concentration basal avalanche of pyroclastic flows. Vertical grading results from the balance between gravitational and dispersive forces, and is transferred to a lateral grading by vertical velocity gradients within a nonturbulent flow zone of pyroclastic flows. The pyroclastic flows are modeled as Bingham-type fluids, a framework that explains some of the basic deposit features even though it is a highly simplified treatment of the flows. Plug flow zones in the flows were a relatively minor part of their thicknesses. Evidence for the flows having had high densities, probably within a factor of two of the final deposit density, is presented. Finally, their origin by "single pulse" or "progressive formation" is discussed.

We calculated production rates of (super 3) H, (super 7) Be, (super 10) Be, (super 14) C, and (super 36) Cl in the atmosphere by both galactic cosmic rays and solar protons, and our calculated production rates for (super 14) C agree well with previous results. Production of atmospheric (super 7) Be and (super 36) Cl by solar protons in polar regions is not negligible. Our production rates and depth dependences for in-situ (super 3) He, (super 10) Be, (super 14) C, (super 21) Ne, (super 26) Al, and (super 36) Cl agree well with experimental measurements for certain minerals in surface samples. The altitude dependence of in-situ production rates was also calculated.

The (super 19) F chemical shift in these layer silicates is characteristic of the structure, in particular, to the local octahedral cation occupancy. Fluoride ions bonded to three Mg octahedral cations have a chemical shift of about -177 ppm and those bonded to two Al cations and a vacancy have a chemical shift of about -134 parts per million (ppm). The shift at -182.8 ppm in hectorite is apparently associated with fluoride bonded to two Al cations and a Li cation. Surprisingly, the difference in chemical shift of the interlayer and inner fluoride in 1:1 layer silicates is insufficient to distinguish these sites. Based on trends in chemical shift, it appears that fluoride substitution for inner hydroxyls in clays with octahedral substitution is not random. Fluoride is apparently preferentially associated with Mg rather than Al in the octahedral sheet as no resonance due to a fluoride bonded to two Al cations and a vacancy is observed in clays such as SAz-1.

These calcretes have been interpreted by some observers as evidence of seismically triggered eruptions of deep water. Such an origin could have important consequences if Yucca Mountain is developed as an unsaturated site for the disposal of high-level nuclear waste. In contrast with local deposits that are of spring or seep origin, the siliceous calcretes at Yucca Mountain are pedogenic in origin as well as evolution and provide no evidence in support of conjectured spring activity.

The shell is sandwiched between a finitely conducting solid inner core and a non-conducting mantle. As the Rayleigh number is increased, the convective motion becomes stronger; when the magnetic Reynolds number becomes larger than a few hundred, dynamo action onsets, and a magnetic field with both axisymmetric and nonaxisymmetric components develops. The magnetic fields generated are generally of the same order of magnitude as the geomagnetic field, and the outer core fluid velocity is consistent with the values deduced from secular variation observations. A mean field approximation is used in which the dynamics of one non-axisymmetric convective mode (the m = 2 mode being most frequently used) and the associated axisymmetric components are followed. This scheme involves significantly less computation than a fully three-dimensional code, but does not require an arbitrary alpha -effect to be imposed. Although the Roberts number, q, the ratio of thermal to magnetic diffusion, is small in the Earth, we find that dynamo action is most easily obtained at larger values of q. The Ekman number in our calculations has been taken in the range O(10 (super -3) )-O(10 (super -4) ), which, although small, is larger than the appropriate value for the Earth's core. At q = 10 we find solutions at Rayleigh numbers close to critical; two such runs are presented, one corresponding to a weak field dynamo, another to a strong field dynamo; the solution found depends on the initial conditions. At q = 1, the solutions have a complex spatial and temporal structure, with few persistent large-scale features, and our solutions reverse more frequently than the geodynamo. The final run presented has an imposed stable region near the core-mantle boundary. This solution has a weaker non-axisymmetric field, which fits better with the observed geomagnetic field than the solution without the stable layer.

Two types of low temperature hydrothermal systems are associated with the 1980 eruptions and were initiated soon after emplacement of shallow magma and pyroclastic flows. The Loowit hot spring system is located in the breach zone and is associated with the magma conduit and nearby avalanche deposits, whereas the Pumice Plain (PP) system is associated with pyroclastic flows and avalanche deposits nearly equal 3 to 5 km north of the volcano. The PP waters first discharged at the surface in 1981, whereas the Loowit waters began to issue at the surface in 1983. delta D, delta (super 18) O and (super 3) H indicated all thermal waters are dominantly derived from post-1980 recharge. Fluids flow through, and are restricted to, the shallow 1980 avalanche and pyroclastic deposits. All water cooled with time (up to 43 degrees C on the PP and up to 20 degrees C in Loowit in 5 years), and chemical compositions have changed rapidly. All waters have highly variable, and unreliable geothermometer temperatures with maximum indicated temperatures <185 degrees C. None of the fluids are at equilibrium with host rocks; dissolution of host rocks as a function of fluid temperature occurs at all sites. Although fluid chemistry varied dramatically in the early years of this study, all waters had similar Li/Cl ratios by 1989 indicating partial stabilization and demonstrating the similarity in host rock compositions at the thermal areas. Loowit waters exhibit delta D and delta (super 18) O enrichments from the meteoric water line and B/Cl ratios (0.02 to 0.05) similar to those in dome fumarole condensates, indicating a < or =10% contribution of magmatic volatiles to these waters. The PP waters generally do not exhibit isotopic enrichments, and the B/Cl ratios are nearly equal 1 order of magnitude less than those in Loowit. No magmatic volatiles enter PP waters, and this system is driven by meteoric water circulation within the cooling pyroclastic flows and underlying avalanche deposits. The PP system will likely cool rapidly to form a nonthermal system. Similar, transient, low-temperature hydrothermal phenomena probably have been associated with other ash-flow sheets, yet have thus far been largely undocumented.

Ulysses encountered fast wind throughout this time except for a 43 degree band centered on the solar equator. Median mass flux was nearly constant with latitude, while speed and density had positive and negative poleward gradients, respectively. Solar wind momentum flux was highest at high latitudes, suggesting a latitudinal asymmetry in the heliopause cross section. Solar wind energy flux density was also highest at high latitudes.

AN - 85238742; pmid-8633766 AB - Significantly improved sensitivity for analysis of biomolecules by MALDI FT-ICR mass spectrometry is achieved by (i) microscope-monitored sample deposition onto a small indentation on the probe tip and (ii) multiple remeasurement of ions from a single laser shot. A simple modification to the solids probe tip allows for microdeposition of a few amols of analyte onto small indentation spots previously aligned with the laser beam. Ion multiple remeasurement of the same ion packet enhances the signal-to-noise ratio and thus extends the achievable FT-ICR MS detection limit. We demonstrate that FT-ICR can be used to detect parent and structurally significant fragment ions of peptides and phospholipids at low amol amounts. Positive ion mass spectra for approximately 90 amol of a mixture of angiotensin II and bradykinin, approximately 40 amol of dipalmitoylglycerophosphatidylcholine, and approximately 8 amol of substance P constitute the lowest reported detection limits to date for FT-ICR mass analysis of MALDI-generated ions.

AN - 77700463; 7497356 AB - Many microbes reduce the nitro substituents of 2,4,6-trinitrotoluene (TNT), producing aminodinitrotoluenes (ADNTs). These compounds are recalcitrant to further breakdown and are acutely toxic. In a search for organisms capable of metabolizing ADNTs, a bacterial strain was isolated for the ability to use 2-aminobenzoate (anthranilate) as sole C-source. This isolate, Pseudomonas aeruginosa MA01, metabolized TNT by first reducing one nitro group to form either 2-amino-4,6-dinitrotoluene (2ADNT) or 4-amino-2,6-dinitrotoluene (4ADNT). However, strain MA01 was distinct from other TNT-reducing organisms in that it transformed these compounds into highly polar metabolites through an O2-dependent process. Strain MA01 was able to cometabolize TNT, 2ADNT, and 4ADNT in the presence of a variety of carbon and energy sources. During aerobic cometabolism with succinate, 45% of uniformly ring-labeled [14C]TNT was transformed to highly polar compounds. Aerobic cometabolism of purified [14C]2ADNT and [14C]4ADNT with succinate as C-source produced similar amounts of these polar metabolites. During O2-limited cometabolism with succinate as C-source and nitrate as electron acceptor, less than 8% of the [14C]TNT was transformed to polar metabolites. Purified 2,6-diamino-4-nitrotoluene was not metabolized, and while 2,4-diamino-6-nitrotoluene was acetylated, the product (N-acetyl-2,4-diamino-6-nitrotoluene) was not further metabolized.

We present results of numerical calculations demonstrating that, for Elsasser numbers Lambda or =1 the fully developed convection consists of magnetostrophic flow inside the tangent cylinder and large-scale spiraling geostrophic flow outside. Interaction of the geostrophic flow with toroidal field induces patches of concentrated poloidal field, which combine to produce the external dipole. The magnetostrophic component of the flow induces very little poloidal field. The external dipole field is nearly axial for small Lambda , whereas for large Lambda the external dipole is inclined and precesses about the rotation axis.

We have modified a three-dimensional, prognostic, higher-order turbulence model for atmospheric circulation (HOTMAC) and a Monte Carlo dispersion and transport model (RAPTAD) to treat domains that include an urbanized area. We used the meteorological model to drive models which describe the photochemistry and air transport and dispersion. The photochemistry modeling is described in a separate paper. We tested the model against routine measurements and those of a major field program. During the field program, measurements included: (1) lidar measurements of aerosol transport and dispersion, (2) aircraft measurements of winds, turbulence, and chemical species aloft, (3) aircraft measurements of skin temperatures, and (4) Tethersonde measurements of winds and ozone. We modified the meteorological model to include provisions for time-varying synoptic-scale winds, adjustments for local wind effects, and detailed surface-coverage descriptions. We developed a new method to define mixing-layer heights based on model outputs. The meteorology and dispersion models were able to provide reasonable representations of the measurements and to define the sources of some of the major uncertainties in the model-measurement comparisons.

The final research goal is to estimate how fast and how much contaminated sediment is moving in the canyon. Due to equation of state experiments involving high explosives, soils in the vicinity of the three test sites have been contaminated with heavy metals such as uranium and cadmium. There are three main parts to the research that will eventually be combined to address the final goal of estimating total contaminant movement. The first part involves the collection and interpretation of experimental field data, such as rainfall and runoff amounts. The second part involves numerical modeling the watershed response to rainfall inputs. The third part involves experimental chemistry work to evaluate the concentration of contaminants in a representative sample of sediment. The details about the model development and testing are presented. The simulation of a large flood in 1991 did not compare well with observations of the event. The model seriously underpredicted the flow out of the watershed because the value of the hydraulic conductivity in the channel was too large. The infiltration of water into the channel bed, known as transmission losses, is a direct function of hydraulic conductivity. Field measurements of hydraulic conductivity yielded values that are much larger than those found in the literature. Consequently, the high input values of hydraulic conductivity produced model results that underestimated the flow. Future research on the process of transmission losses is recommended to resolve this issue and improve the accuracy of the model results.

This problem has particular significance when trying to image strongly contrasting low-velocity bodies, such as magma chambers, because strongly refracted and/or diffracted rays may precede the direct P wave arrival traditionally used in straight-ray seismic tomography. We use a simplex-based ray tracer to compute the three-dimensional, minimum travel time ray paths and employ an iterative inversion technique to cope with nonlinearity. Results from synthetic data show that our algorithm results in better model reconstructions compared with traditional straight-ray inversions. We reexamine the teleseismic data collected at Long Valley caldera by the U. S. Geological Survey. The most prominent feature of our result is a 25-30% low-velocity zone centered at 11.5 km depth beneath the northwestern quadrant of the caldera. Beneath this at a depth of 24.5 km is a more diffuse 15% low-velocity zone. In general, the low velocities tend to deepen to the south and east. We interpret the shallow feature to be the residual Long Valley caldera magma chamber, while the deeper feature may represent basaltic magmas ponded in the midcrust. The deeper position of the prominent low-velocity region in comparison to earlier tomographic images is a result of using three-dimensional rays rather than straight rays in our ray tracing. The magnitude of our low-velocity anomaly is a factor of approximately 3 times larger than earlier models from linear arrival time inversions and is consistent with models based on observations of ray bending at sites within the caldera. Our results imply the presence of anywhere from 7 to 100% partial melt beneath the caldera. Copyright 1995 by the American Geophysical Union.

AN - 77443950; 7635727 AB - 241Am was determined radiochemically in the tissues of USTUR Case 246, a 76-y-old man who died of cardiovascular disease 11 y after massive percutaneous exposure following a chemical explosion in a glove box. This worker was treated extensively with a chelation drug, DTPA, for over 4 y after exposure. The estimated 241Am deposition at the time of death was 540 kBq, of which 90% was in the skeleton, 5.1% in the liver, and 3.5% in muscle and fat. Among the soft tissues, the highest concentrations were observed in liver (22 Bq g-1), certain cartilaginous structures such as the larynx (15 Bq g-1) and the red marrow (9.7 Bq g-1), as compared with the mean soft tissue concentration of approximately 1 Bq g-1. Concentration in muscle was approximately that of the soft tissue average, while concentrations in the pancreas, a hilar lymph node and fat were less than the average. Concentrations in bone ash were inversely related to the ratio of ash weight to wet weight, a surrogate for bone volume-to-surface ratio. The distribution of activity in this case is reasonably consistent with that observed in another human case, when allowance is made for chelation therapy, and also tends to support more recent models of 241Am metabolism.

This solution, which serves as a crude analog for the geodynamo, is a self-sustaining supercritical dynamo that has maintained a magnetic field for three magnetic diffusion times, roughly 40 000 years. Fluid velocity in the outer core reaches a maximum of 0.4 cm s (super -1) , and at times the magnetic field can be as large as 560 gauss. Magnetic energy is usually about 4000 times greater than the kinetic energy of the convection that maintains it. Viscous and magnetic coupling to both the inner core below and the mantle above cause time-dependent variations in their respective rotation rates; the inner core usually rotates faster than the mantle and decadal variations in the length of the day of the mantle are similar to those observed for the Earth. The pattern and amplitude of the radial magnetic field at the core-mantle boundary (CMB) and its secular variation are also similar to the Earth's. The maximum amplitudes of the longitudinally averaged temperature gradient, shear flow, helicity, and magnetic field oscillate between the northern and southern hemispheres on a time scale of a few thousand years. However, only once in many attempts does the field succeed in reversing its polarity because the field in the inner core, which has the opposite polarity to the field in most of the outer core, usually does not have enough time to reverse before the field in the outer core changes again. One successful magnetic field reversal occurs near the end of our simulation.

Previous studies showed that this mainly trachytic deposit, composed of two members, was erupted by (1) a central-vent, mostly phreatoplinian phase (Lower Member) that generated pyroclastic surges and fallout reaching 34 km from the vent, followed by (2) a multiple-vent, phreatomagmatic and magmatic phase (Upper Member) associated with onset of caldera collapse that produced surges extending 14 km from the vent. The Lower Member is well bedded and comprises 13 subunits that alternate between phreatoplinian surges/flows and Plinian pumice-and-ash fallout. The Upper Member is relatively lithic-rich and more massive in character. For both members, magma compositions vary from alkali trachyte through trachyte to latite, which does not fit a simple inversion of magma chamber gradients. Calculations based on magma chemistry show an increase in magma density, a decrease followed by an increase in viscosity, and a general decrease of gas fraction during the course of both eruptive phases. After migrating to a depth of about 400 m, calculated fragmentation depths gradually rise during each phase. Application of sequential fragmentation/transport analysis to granulometric data shows for the lower member an average ratio of phreatomagmatic to magmatic components of 70:30 while the upper member shows an average ratio of 80:20. However, considering the tephra volume represented by samples, computed water/magma interaction ratios (R) are shown to fluctuate, but generally decrease from about 0.65 to 0.05 during eruption of the Lower Member while the Upper Member shows R fairly constant at about 0.1. Furthermore, surge/flow runout distances and estimates of eruptive velocities from R values show that column collapse heights were extremely high (6 to 7 km) during the first phase and were substantially lower during the second phase (2 to 3 km). Vent radii required for calculated eruption velocities of 180 to 370 m/s are between 70 and 300 m, suggesting a cumulative eruption duration of over 10 hours, perhaps spanning of one to several days.

AN - 36406915; 5321 AB - PURPOSE: The construction of a dual-axis radiographic hydrodynamic test facility at the Department of Energy's (DOE's) Los Alamos National Laboratory (LANL) in New Mexico is proposed. Hydrodynamic tests are essential elements in evaluating and understanding the physical properties and dynamic behavior of materials used in nuclear weapons. The tests are used to obtain information on the behavior of the weapon and to evaluate the effects of aging. The tests are performed on mock-ups of nuclear weapons and do not result in nuclear detonation or nuclear yield; instead, high explosives are detonated and the resulting motions and reactions of materials and components are observed and measured. Uncertainty about the condition of the U.S. nuclear weapons stockpile will increase with the passing of time, and the DOE can no longer use nuclear testing to assess the safety and reliability of weapons. Radiographic hydrodynamic testing is now conducted at two existing DOE facilities: the pulsed high-energy radiation machine emitting X-rays (PHERMEX) located at LANL and the Flash X-Ray Facility at the Lawrence Livermore National Laboratory. The new radiographic facility would provide high-resolution, multiple-time, multiple-view images of reactions occurring following detonation, images far superior to those provided by existing systems. Six alternatives, including a No Action Alternative, are considered in this final EIS. Under the preferred alternative, the DOE would complete the new radiographic facility and implement an enhanced containment strategy for testing at the new facility so that most tests would be conducted inside steel vessels, and phase out operations at PHERMEX. The capital costs of the project would be roughly $87 million for 1995 to 2000, and annual operation costs would range from $4.0 million to $7.0 million during that period. POSITIVE IMPACTS: The project would assist in the management of the U.S. nuclear weapons stockpile. Radiographic testing would create benchmarks for weapons as they age. NEGATIVE IMPACTS: Detonations at the new facility would create serious noise disturbances. Uranium contamination would adversely affect a 15-acre area.

AN - 77593077; 7493070 AB - Staurosporine (Stsp), a protein kinase inhibitor, has been found to have a differential effect on the proliferation of normal and transformed cells in vitro. Hence, Stsp might be used in cancer therapy to arrest normal proliferating cells in G1, while permitting tumor cells to continue proliferation. The patient could then be treated with a therapeutic agent of maximum toxicity for actively proliferating tumor cells. To facilitate investigations of Stsp in vivo, we have developed an HPLC method for measuring the levels of Stsp in blood. Using a rat model, plasma containing Stsp is treated with acetone to precipitate proteins and extract the Stsp. The acetone extract is then subjected to reversed-phase HPLC on a mu Bondapak C18 column. Using a linear elution gradient of acetonitrile containing trifluoroacetic acid, Stsp elutes as a sharp peak at ca. 35 min which can be detected by UV absorption at 292 nm. No blood or reagent components interfere with its quantification. The calibration curve, ranging from 0.1 to 2.0 micrograms Stsp, demonstrated a linear response to Stsp concentration having a correlation coefficient (r2) of 0.990. Precision analysis demonstrated that the method will yield results that are +/- 11.6% from the mean 95% (two standard deviations) of the time. This method was used to measure Stsp levels in plasma after administering an injection of 0.2 mg Stsp into the jugular vein of rats. No Stsp could be detected in the plasma 5 min after injection, even though enough Stsp was administered to be easily detectable if it was simply contained in the plasma. Thus, it is concluded that some compartment other than the plasma must adsorb the Stsp from the plasma and sequester it in vivo. JF - Journal of chromatography.

AN - 77551864; 8547224 AB - 12-O-Tetradecanoylphorbol-13-acetate (TPA) and cholera toxin have been shown previously to act synergistically to stimulate traverse of G0-G1 and entry into S phase in quiescent mouse fibroblasts. These agents also have a synergistic effect on the induction of the endogenous c-fos gene, as well as a transfected reporter construct containing the mouse fos promoter/enhancer region from -397 to +1 cloned upstream of luciferase. A detailed mutational analysis of the c-fos-regulatory region revealed that the synergy between TPA and cholera toxin requires multiple discrete elements, including the binding sites for the serum response factor (-308 to -299), p62/Elk-1 (-316 to -309), on the 5' side of the serum response element, and a CCAAT or E box-binding protein(s) on the 3'-flanking side of the serum response element (-303 to -295 or -297 to -292, respectively). The putative cyclic AMP response element (-65 to -58), shown to be activated in a number of cell types after increases in cyclic AMP levels, mediated an induction by TPA but not by cholera toxin in AKR-2B cells, and was not required for the synergistic transactivation induced by the combination of TPA and cholera toxin.

Waveforms recorded at caldera stations are considerably more complex than those recorded outside the caldera. The data used in this study were collected during a passive seismic monitoring experiment conducted in 1987. Twenty-four teleseismic events were recorded on two linear arrays spanning the caldera. To first order, the pattern of low amplitudes did not vary with source incidence angle or azimuth of approach, and could not be explained by anomalous amplification at the ring fracture. This observation suggests the presence of a shallow, attenuating zone associated with the caldera fill material inside of the ring fracture. We estimated the general features of the caldera's near-surface structure for the two-dimensional vertical cross section beneath the array, using a modification of the Aki-Larner discrete-wavenumber method to forward model the observed amplitude variations. Our results indicate that the caldera fill material must be subdivided into at least two distinct zones: a strongly attenuating lower zone, extending to depths in excess of 4 km, and a mildly attenuating surface layer. To fit the data we had to assign an unrealistically low value to seismic Q in the deeper attenuating anomaly. We attribute this to the inability of the Aki-Larner method to account for strong re-direction of energy away from the caldera due to local heterogeneity that we could not include within the low-Q anomaly. This interpretation is consistent with the pervasive, fractured hydrothermal system that is known to exist in the caldera fill material.

Relatively high T (sub h) values in samples from shallow depths indicate erosion of about 200 m of caldera fill since deposition of hydrothermal minerals at shallow depths in the Sulphur Springs hydrothermal system, accompanied by a descent in the water table of the liquid-dominated reservoir. For samples collected below the current water level of the well, the minimum values of homogenization temperature (T (sub h) ) fit the present thermal profile, whereas minimum T (sub h) values of samples from above the water level are several tens of degrees higher than the present thermal profile and fit a paleo-thermal profile following the boiling point curve for pure water, as adjusted to 92 degrees C at 20 m below the present land surface. This is attributed to development of an evolving vapor zone that formed subsequent to a sudden drop in the water table of the liquid-dominated reservoir. We suggest that these events were caused by the drainage of an intracaldera lake when the southwestern wall of the caldera was breached about 0.5 Ma. This model indicates that vapor zones above major liquid-dominated geothermal reservoirs can be formed due to dramatic changes in geohydrology and not just from simple boiling.

The data are compared to dissolution rates of hematite measured in the presence of protons alone and of the representative weathering ligands oxalate and ascorbate. Siderophores are highly Fe(III)-specific bidentate ligands excreted by aerobic and facultative anaerobic microorganisms facilitating Fe uptake in oxic environments. The comparability of dissolution rates found for the soil bacterium siderophore and two terrestrial organic ligands (despite an order of magnitude differences in their initial concentrations), suggests that siderophores may be significant in Fe(III)-mineral weathering reactions under natural conditions.

The experiment exposed the mechanisms by which an off-axis plume overcomes the lithospheric drag that draws material away from a ridge to feed a nearby spreading centre. An off-axis plume may connect thermally and chemically with a spreading ridge through a narrow, sub-horizontal conduit (requiring a lithospheric or rheological boundary layer thickening away from the ridge axis due to conductive cooling), instead of a broader, radially spreading plume head. For high plume T, increasing the plume thermal buoyancy may inhibit rather than enhance plume-ridge interaction due to increased erosion of the overlying lithosphere.

The (super 3) H concentrations in precipitation are used to calculate fluid mean residence times using two end-member cases: piston-flow and well-mixed reservoirs. These simplified models using (super 3) H yield relative fluid mean residence times in different portions of the system. In-situ (super 3) H production in the reservoir through neutron interaction with (super 6) Li is considered, and only very low levels of (super 3) H (10,000 years) than waters in the Sulphur Springs subsystem ( approximately 2000-4400 years). Comparison of the results of the end-member cases with those obtained using more sophisticated methods indicates that the two end-member cases, with the use of (super 3) H, can provide acceptable limits (order of magnitude) on a fluid's mean residence time and volumes within a reservoir.

Four samples were analyzed to obtain both zircon ages and track length data from Permian strata to Precambrian quartz monzonite, the present temperatures of which are from 222 to 294 degrees C. Zircon ages obtained from the deeper three samples indicate partially annealed ages of about 450-600 Ma. Thus, zircons from Permian strata probably originated from Precambrian rocks. Contrary to the normal relationship between FT ages and temperatures of the sampling points, non-correlation between them is probably due to hot fluid flow and/or hot vein emplacement associated with recent volcanic activity. Zircon ages of the shallowest sample were much younger than the Permian, the reason for which is unknown. The closure temperature of the zircon fission-track dating method seems to be higher than that previously determined from geological data.

Our principal objectives were: (1) to examine the mobility of these elements during post-eruptive devitrification and hydration; and (2) to study their behavior during magma differentiation. Compared to fresh glassy samples, devitrified rocks from the same dome are depleted in B, Li, F and Cl, but not in Be. During devitrification, Be was immobile while the other elements were progressively more mobile in the order B or =130 ka) and that recent revisions to the post-0.5 Ma stratigraphy of Valles caldera are probably in error. The results suggest that ESR dating of quartz may be a useful method for obtaining ages of units in other Quaternary volcanic areas.

Among other units, the hole penetrated 760.2 m (2494.1 ft) of Paleozoic carbonate and siliciclastic strata underlying caldera fill and precaldera volcanic and epiclastic rocks. Comparison of the VC-2B Paleozoic rocks with corresponding lithologies within and around the 32.1 Ma Socorro caldera, 192 km (119 miles) to the south-southwest, provides insight into the variability of alteration responses to similar caldera-related hydrothermal regimes. The Pennsylvanian Madera Limestone and Sandia Formation from VC-2B preserve many of the sedimentological and diagenetic features observed in these units on a regional basis and where unaffected by high temperatures or hydrothermal activity. Micrites in these formations in VC-2B are generally altered and mineralized only where fractured or brecciated, that is, where hydrothermal solutions could invade carbonate rocks which were otherwise essentially impermeable. Alteration intensity (and correspondingly inferred paleopermeability) is only slightly higher in carbonate packstones and grainstones, low to intermediate in siltstones and claystones, and high in poorly cemented sandstones. Hydrothermal fracture-filling phases in these rocks comprise sericite (and phengite), chlorite, allanite, apatite, an unidentified zeolite and sphene in various combinations, locally with sphalerite, galena, pyrite and chalcopyrite. Terrigenous feldspars and clays are commonly altered to chlorite and sericite, and euhedral anhydrite "porphyroblasts" with minor chlorite occur in Sandia Formation siltstone. Fossils are typically unaltered, but the walls of some colonial bryozoans in the Madera Limestone are altered to the assemblage chlorite-sericite-epidote-allanite. La, Ce and Nd are present in an unidentified hydrothermal mineral occurring throughout much of the VC-2B Pennsylvanian sequence. Carboniferous carbonate and siliciclastic formations within and around the Socorro caldera show a similar style of alteration and mineralization to their Valles caldera counterparts, but by contrast locally host commercial, caldera-related, base-metal sulfide deposits. As in the Valles rocks, mineralization and alteration in those of the Socorro caldera were strongly controlled by porosity. Unless disrupted by fractures, breccias, or karst cavities (not identified in Valles caldera drill holes), the rocks remained relatively unaltered. Where these features allowed ingress of mineralizing hydrothermal solutions, base-metal sulfides and rare-earth-element-bearing minerals were precipitated.

Aspects of these systems may be analogous to conditions expected in a potential site for a high-level waste repository in welded tuff. Examination of radioelements in core from scientific drill holes at these sites was accomplished by gamma-ray spectrometry and fission-track radiography. In the lateral-flowing hydrothermal system at the Long Valley caldera, where temperatures range from 140 to 200 degrees C, U is concentrated to 20 ppm in Fe-rich zones of varved tuff and to 50 ppm with Fe-rich mineral phases in tuff fragments of a calcite-cemented breccia. U-series disequilibrium in some of these samples suggests mobilization/deposition of parent U and/or its daughters. In the vapor zone of the Valles caldera's hydrothermal system (temperature approximately 100 degrees C), the concordance of high U, low Th/U and decreasing whole-rock O-isotope ratios suggests that U was concentrated in response to hydrothermal circulation when the system was formerly liquid-dominated. In the underlying present-day liquid-dominated zone (temperature to 210 degrees C), U, up to several tens of parts per million, occurs with pyrite and Fe-oxide minerals, and in concentrations to several percents with a Ti-Nb-Y-rare earth mineral. In the Valles system's outflow zone, U is also concentrated in Fe-rich zones as well as in carbonaceous-rich zones in the Paleozoic sedimentary rocks that underlie the Quaternary tuff. Th, associated with accessory minerals, predominates in breccia zones and in a mineralized fault zone near the base of the Paleozoic sedimentary sequence. Relatively high concentrations of U occur in springs representative of water recharging the Valles caldera's hydrothermal system. In contrast, considerably lower U concentrations occur in hot waters (>220 degrees C) and in the system's outflow plume, suggesting that U is concentrating in the hotter part of the system. The Long Valley and Valles observations indicate that U and Ra are locally mobile under hydrothermal conditions, and that reducing conditions associated with Fe-rich minerals and carbonaceous material are important factors in the adsorption of U, and thus can retard its transport in water at elevated temperature.

The complex is one of the major silicic centers in the Trans-Mexican Volcanic Belt (TMVB). Pradal and Robin (1985) first suggested the existence of the Los Azufres caldera, and Ferrari et al. (1991) recognized the existence of a collapse structure. According to Pradal and Robin this is a caldera of resurgent type. This geophysical study aims to contribute to the knowledge of the structure of the Los Azufres area. Gravity, aeromagnetic, magnetotelluric (MT) and d.c. vertical electric-resistivity soundings were analyzed. Results show that Los Azufres is a very structurally complex setting with relatively thin crust caused by the extensional tectonics characterizing this central sector of the TMVB. Faults belonging to the E-W to NE-SW (extensional neotectonics) and NW-SE (Basin and Range province) systems are observed to affect the geologic units of Los Azufres. According to our study, the Los Azufres geothermal field is located in a structural high located in the middle of a sub-circular depression delimited to the north-northeast by the Santa Ines Range, and to the southwest by the Mil Cumbres formation. The larger depression consists of two narrow, deep depressions that correspond to La Venta and to the Valley of Juarez. They are separated by the above mentioned structural high. These sub-depressions are believed to be the sites of a maximum caldera collapse, and the structural high is interpreted to be at least in part the caldera's resurgent dome. Geoelectric structure of the caldera derived from d.c. resistivity indicates that the brines of the Los Azufres geothermal system ascend along faults, both bounding and internally disrupting the structural high/resurgent dome. A reasonable correlation is observed between gravity and aeromagnetic data. JF - Journal of Volcanology and Geothermal Research AU - Campos-Enriquez, J O AU - Garduno-Monroy, V H A2 - Gardner, J. N.

Much of the sub-caldera tuff-lava sequence, also exposed in the topographic caldera walls, is the product of several ca. 2-Ma-old overlapping stratocones formerly present in the area, but later subjected to subsidence and edifice collapse. The V-shaped gravity anomaly across the caldera is due to a funnel-shaped cross section, developed as follows. The earliest and innermost (now concealed) down-faulted zone was filled by a low-density pumice unit which extended southwest along an early arc-normal graben. At least two subsequent subsidence events produced the present scarps and outflow tuff-breccias, but the erupted volume is markedly lower than the subsidence volume. The missing magma may have been diverted to the east, where, at the same time, further stratocone buildup was occurring. The gravity signature over this eastern caldera margin suggests the presence of a large, dense sub-volcanic intrusive complex. Further edifice collapse and graben formation, due to a combination of gravitational failure and arc-normal strain, are relatively recent and continuing processes. The evolution of the Guayabo caldera therefore involved a series of subsidence events punctuated by stratocone buildup and collapse. The resolution of concentric, ring-faulted block structures does not support a chaotic collapse model but, instead, indicates the incremental development by widening of a funnel-shaped caldera.

Temporal trends of increasing epsilon (sub Nd) values and decreasing (super 87) Sr/ (super 86) Sr ratios of the ash-flow tuffs suggest that extensive crustal hybridization of both upper-and lower-crustal reservoirs occurred as a result of magmatism. Mantle-derived basalts are envisioned to have initially crystallized and significantly interacted with crust near the crust-mantle boundary, creating a hybrid crust that is a mixture of mantle and lower-crustal components. Evolved magmas ascended into the upper crust, where they continued to assimilate and crystallize, modifying the bulk upper-crustal composition through transfer of both lower-crustal and mantle components into the upper crust, strongly affecting the isotopic compositions of the lower and upper crust. Lower-crustal epsilon (sub Nd) values and (super 87) Sr/ (super 86) Sr ratios are calculated to have shifted >30-40% toward mantle compositions during these processes, although Pb isotope compositions of the lower crust are not as strongly affected (<30% shift to mantle compositions). Depending on the extent of upper crust-lower crust recycling, upper-crustal epsilon (sub Nd) values shift 15-30% toward mantle compositions, (super 87) Sr/ (super 86) Sr ratios shift 20-55% toward lower-crustal and mantle ratios and (super 206) Pb/ (super 204) Pb ratios decrease 15-25% toward lower-crustal ratios. Crustal hybridization during evolution of the central caldera cluster was intense, although hybridization in the upper crust was localized to the region immediately underlying the calderas. Two distinct isotopic cycles are recognized in the ash-flow tuffs, one from 27.8 to 26.9 Ma (first caldera cycle) and the second from 26.4 to 26.1 Ma (San Luis caldera cycle). The break between the two cycles may be due to a shift in the locus of magmatism to the northwest, into an area of relatively unhybridized, original Proterozoic crust. Isotopic compositions of the caldera-related lavas are variable, and unlike the ash-flow tuffs, there are no distinctive temporal trends. The lavas are believed to undergo late-stage evolution in smaller magma chambers surrounding the caldera cluster, where the crust has not been as intensely hybridized. The comparatively large isotopic variability of the lavas reflects the high susceptibility of small magma chambers to isotopic modification during interaction with heterogeneous crust. In contrast, ash-flow magmas evolve in much larger magma chambers which tend to average isotopic heterogeneity of crust and mantle end-members, and the isotopic compositions of the tuffs serve as a better monitor of changes in the average composition of the magmatic system and the crustal column.

The intrusions are aphyric to sparsely plagioclase-phyric, high-silica, high-barium and low-strontium rhyolites. They resemble the lavas of the Early Rhyolite, the first phase of post-caldera volcanism. A mean (super 40) Ar/ (super 39) Ar age of 590+ or -17 ka from a part of a shallow intrusion is coeval with Early Rhyolite volcanism. A second mean age of 454+ or -17 ka from the same intrusion may reflect either younger Early Rhyolite activity with no external equivalent or hydrothermal resetting of the argon system. Hydrothermal alteration of the intrusions is characterized by introduction of quartz, calcite and pyrite and formation of illite/smectite. High CO (sub 2) content of fluids apparently inhibited zeolite formation. Alteration varies locally within intrusions and intrusive groups and does not vary systematically with depth. Oxygen shows consistent depletion of the (super 18) O isotope from an initial magmatic composition of +6.0 to +8.5 per mil to values ranging from +1.4 to -0.4 per mil. The constant oxygen isotope depletion most likely reflects alteration of intrusions due to local emplacement-induced hydrothermal circulation rather than a caldera-scale hydrothermal system. In contrast, (super 18) O depletion of the host Bishop Tuff increases regularly with depth (except at an intrusive contact). A pre-Early Rhyolite geothermal gradient of approximately 70 degrees C/km was inferred. This is substantially higher than the current gradient but substantially lower than expected for the case of a conductive regime over a shallow residual magma chamber. Either the intrusions were fed from a deep chamber, or a cool hydrologic recharge regime was established early in caldera history. The age, thickness and suspected lateral extent of these shallow intrusions are such that emplacement of the intrusions, rather than inflation of a shallow chamber, is responsible for resurgence of the central Long Valley Caldera. Similar intrusions occur in another well on the resurgent dome (LV13-21) but not in wells located off the dome.

This renovation project, which will correct those deficiencies and allow operation of the facility, is proposed as an FY 97 line item. The mission of the project is to provide centralized intermediate and long-term storage of special nuclear materials (SNM) associated with defined LANL programmatic missions and to establish a centralized SNM shipping and receiving location for Technical Area (TA)-55 at LANL. The project will enable long-term, cost-effective storage in a secure environment with reduced radiation exposure to workers, and eliminate potential exposures to the public.

A newly proposed model for pavement evolution differs from these models in that pavement clasts are continuously maintained at the land surface in response to deposition and pedogenic modification of windblown dust. In-situ cosmogenic (super 3) He surface-exposure ages on volcanic and alluvial landforms in the Mojave Desert of California are used to understand pavement evolution over geologic time scales and to test this new model. These exposure ages are stratigraphically consistent, show internal consistency at each site, and, for stone pavements adjacent to pristine, continuously exposed volcanic bedrock, are indistinguishable at the 1sigma level. We conclude that stone pavements are born at the surface and that pavements may provide one of the longest-term records of geologic, hydrologic, and climatic processes operating on desert surfaces.

AN - 77368696; 7797537 AB - Processing of mutagenic DNA damages by the double strand breaks (DSB) in eukaryotes is most likely achieved by multiple pathways, including homologous recombination. Although RAD52 has been shown to be important for DSB repair in yeasts, its role in DSB repair in mammalian cells has not been demonstrated. This study reports for the first time that the overexpression of human RAD52 confers enhanced resistance to gamma-rays and induces homologous intrachromosomal recombination in cultured monkey cells. Recombination frequency synergistically increased by the combination of overexpression of RAD52 and ionizing radiation. These observations suggest that homologous recombination mediated by RAD52 is involved in double-stranded break repair in mammalian cells.

This behavior is unlike that exhibited by other Yukon-Tanana samples or by most rocks from other locations. Detailed petrographic examination of the sample revealed the presence of a stringer of carbonaceous material generally less than 10 mu m thick enclosed in and intergrown with one of the muscovite layers and extending for about 2 cm along the foliation. The stringer is probably responsible for the anomalous conductivity change with pressure, making the sample the first for which anomalous electrical conductivity behavior can be attributed to carbon associated with a specific feature. The carbonaceous stringer together with its host muscovite layer are deformed and broken around a rotated garnet porphyroclast. The deformation was accommodated by plastic deformation of quartz and therefore occurred in the ductile regime under conditions at least equivalent to greenschist facies metamorphism. We interpret the textural relations to indicate that the carbonaceous material was formed by fluid deposition in a fracture formed within the muscovite layer, possibly during the main phase of metamorphism and deformation, and that the mica and carbon stringer were then deformed by the noncoaxial deformation responsible for rotation of the garnet porphyroclasts. Together the facts that the deformation resulting in garnet rotation was ductile and that the garnet rotation disrupted the stringer demonstrate that the carbonaceous stringer was present at depth (i.e., > 10 km). Brittle deformation on the microscopic scale is observed to have broken the connectivity of the carbon stringer, explaining in part why the rock does not exhibit anomalously high conductivity at 0.1 MPa (1 atm) pressure. The brittle deformation is interpreted to have been caused by unloading due to uplift. The observations indicate that carbonaceous material may exert a primary control on crustal electrical conductivity because it may be present as interconnected arrays in grain boundaries or microfractures or in megascopic, throughgoing fractures.

The most common enclave type is layered, rich in biotite, cordierite and aluminosilicates, and has textures and compositions that reveal variable degrees of melt extraction from metasedimentary source rocks. Rare sillimanite-bearing enclaves represent residual material, either from the region of magma generation or its ascent path, but most such enclaves were probably derived from the contact aureole closer to the present level of exposure. These non-igneous enclaves (NIE) and their disaggregation products are present in all major plutons, comprising from < 2 to 5 vol.% of the granites. Enclaves of igneous origin are also present in all major plutons except Carnmenellis, generally comprising < 1 vol.% of the granites. The most common type is intermediate in composition, with microgranular texture, and mineral compositions and textures consistent with an origin by magma mixing. Large crystals of K-feldspar, plagioclase and quartz, common in these microgranular enclaves (ME) but absent in NIE, represent phenocrysts derived from the silicic end-member during magma mixing events rather than products of metasomatism as suggested previously. Although the composition of the mafic end-member (basaltic or lamprophyric) involved in the mixing process is poorly constrained, the presence of ME in the granites, and the preponderance of mantle-derived mafic rocks in the coeval Exeter Volcanics, indicate that mafic magma injection into the crust was a factor in the generation of the batholith.

Additionally, single-crystal X-ray data were collected from a synthetic anhydrous rutile crystal and a crystal from the hydrous mantle rutile. The X-ray data were collected to compare the structural details of anhydrous and hydrous rutile. No significant differences were found in the structural details of these two refinements.

Both axisymmetric and planar upflows are considered, and the strong temperature dependence of mantle viscosity is taken into account. For plume strengths considered, a Clapeyron slope of -4 MPa K (super -1) prevents plume penetration of the phase change. Plumes readily penetrate the phase change for a Clapeyron slope of -2 MPa K (super -1) and arrive in the upper mantle considerably hotter than if they had not traversed the phase change. For the same amount of thermal drive, i.e., the same excess basal temperature, axisymmetric plumes are hotter upon reaching the upper mantle than are planar upwellings. Heating of plumes by their passage through the spinel-perovskite endothermic phase change can have important consequences for the ability of the plume to thermally thin the lithosphere and cause melting and volcanism.

At least four different plutonium species, characterized by absorption peaks at 486, 492, 500, and 513 rim, have been found. A redox change to a Pu(VI) complex can not account for the speciation change associated with the first two spectra (486 and 492 nm peaks). Moreover, the data are consistent with what is predicted from a previous YMP milestone. This previous study was performed under very different conditions of plutonium concentration and carbonate/pH changes, and extension of these conditions to much lower Pu concentrations and to more neutral pHs was made possible with PAS spectroscopy. These new results reinforce the previous results by extending the range of direct observation and by eliminating other possibilities such as dimerization/polymerization reactions. As bicarbonate concentration is increased from .01 M to 1.0 M at pH = 8.4 to 8.9, predominately (Pu(OH) (sub x+1) (CO (sub 3) ) (sub y) (super 4-(x+2y)) 4-(x+2y)) (492 nm peak) is converted to (Pu(OH) (sub x) (CO (sub 3) ) (sub y+l) ) (super 4-(x+2y+2)) (486 nm peak). The starting stoichiometry (x and y values) remain undetermined, but the effect of ionic strength and temperature indicate that the 486 nm species is highly charged, and therefore x+2y(ge)3. The temperature effect on the equilibrium between these two species was also investigated, with the species giving rise to the 486 nm peak reversibly losing importance at elevated (50 and 75(degrees)C temperatures).

AN - 50154839; 1995-034707 AB - The Valles caldera formed during two major rhyolitic ignimbrite eruptive episodes (the Bandelier Tuff) at 1.61 and 1.22 Ma, after some 12 m.y. of activity in the Jemez Mountains volcanic field, New Mexico. Several subsequent eruptions between 1.22 and 0.52 Ma produced dominantly high-silica rhyolite lava domes and tephras within the caldera. These were followed by a dormancy of 0.46 m.y. prior to the most recent intracaldera activity, the longest hiatus since the inception of the Bandelier magma system at approximately 1.8 Ma. The youngest volcanic activity at approximately 60 ka produced the SW moat rhyolites, a series of lavas and tuffs that display abundant petrologic evidence of being newly generated melts. Petrographic textures conform closely to published predictions for silicic magmas generated by intrusion of basaltic magma into continental crust. The Valles caldera may currently be the site of renewed silicic magma generation, induced by intrusion of mafic magma at depth. Recent seismic investigations revealed the presence of a large low-velocity anomaly in the lower crust beneath the caldera. The generally aseismic character of the caldera, despite abundant regional seismicity, may be attributed to a heated crustal column, the local effect of 13 m.y. of magmatism and emplacement of mid-crustal plutons. Seismic signals of magma movement in the deep to mid-crust may therefore be masked, and clear seismic indications of intrusion may only be generated within a few kilometres of the surface. We therefore encourage the establishment of a local dedicated volcanic monitoring system.

Some of these minerals may be potential respiratory health hazards. Therefore, an understanding of the distribution of the minerals that may potentially be liberated during site-characterization and operation of the potential repository is crucial to ensuring worker and public safety. Analysis of previously reported mineralogy of Yucca Mountain tuffs using data and criteria from the International Agency for Research on Cancer (IARC) suggests that the following minerals are of potential concern: quartz, cristobalite, tridymite, opal-CT, erionite, mordenite, and palygorskite. The authors have re-evaluated the three-dimensional mineral distribution at Yucca Mountain above the static water level both in bulk-rock samples and in fractures, using quantitative X-ray powder diffraction analysis. Erionite, mordenite, and palygorskite occur primarily in fractures; the crystalline-silica minerals, quartz, cristobalite, and tridymite are major bulk-rock phases. Erionite occurs in the altered zone just above the lower Topopah Spring Member vitrophyre, and an occurrence below the vitrophyre but above the Calico Hills has recently been identified. In this latter occurrence, erionite is present in the matrix at levels up to 35 wt%. Mordenite and palygorskite occur throughout the vadose zone nearly to the surface. Opal-CT is limited to zeolitic horizons.

When normalized as CaCO (sub 3) -free values and ratioed to Al, a small excess of Ir over background levels was found in and on the upper surface of an oncolite platform bed in the Ellis Bay formation. Although an extraterrestrial impact cannot be ruled out for this Ir maximum near the end of the Ordovician, which seems to be stratigraphically coeval and widespread in the world, all of them are found to be associated with sedimentary condensation that may have resulted from glacio-eustatic sea-level fluctuations at the end of the Ordovician. Certain elements, e.g. Th, La, Lu, Sc, Cr, Ir, Fe, Al, Ca, show distinct abundance patterns in limestones, calcareous shales and clays, apparently as a result of increasing clay mineral contents.

PIXE spectra are quantified using a least-squares data reduction method by normalization to S determined by electron microprobe in macerals and to Fe determined by mineral stoichiometry in Fe sulfides. Application of the PIXE technique to vitrinite macerals and Fe sulfides from channel samples of the Lower Kittanning Coal Bed of western Pennsylvania suggests that Ni, Cu, As, Se, Mo, and Pb are associated with Fe sulfides and Cl, Ca, Ti, Ge, Ga, and Br are associated with vitrinite macerals. Organic S is higher in marine-influenced macerals within the Lower Kittanning coal. Similarly, As/Se and Mo/Se are higher within Fe sulfides from the marine-influenced coals. Devolatilization of coal beds may be a plausible source of complexing ions and metals for ore deposit formation. Such fluids may be characterized by low Cl/Br relative to most hydrothermal fluids.

At constant T, increasing P (7-20 kbar) causes little change in the liquid carbonate/liquid carbonate/liquid silicate partition coefficients (D); at constant P, increasing T causes all D values to approach unity as the T approaches the critical value and the two liquids become compositionally similar. Addition of P and F to the system does not affect the partitioning behaviour of these elements, but P and F are strongly partitioned into the carbonate liquid. Omphacite/carbonate liquid D values are also reported. Th is more compatible than U in pyroxene; excesses of (super 230) Th/ (super 238) U in MORB are not explained by fractionation between pyroxene and melt. Fractionations of Pb, U and Ra isotopes in carbonatite lavas from the Oldoinyo Lengai volcano, Tanzania, are discussed in light of the experimental results. Carbonate-silicate interactions produce modest fractionations between nominally incompatible elements, but the composition of the carbonate has only a slight influence on carbonate-silicate partitioning.

AN - 77307622; 7774531 AB - Exercise performed after exposure to various pneumoedematogenic gases can increase the severity of pulmonary edema beyond that which occurs when exposure is followed by rest. The present study was performed to investigate the potential relationship between a preexisting breach in the lung's permeability status following exposure to an edematogenic gas (perfluoroisobutylene, PFIB) and the potentiating effects of postexposure exercise. Rats were exposed to a concentration of PFIB (100 mg/M3 for 10 min) that results in a unique postexposure latency period (approximately 8 h) prior to the occurrence of overt pulmonary edema. The study examined how exercise performed during and after the latency period affects the severity of the injurious response to this toxic gas. The initial results indicated that exercise performed during the post-PFIB exposure latency period does not potentiate the injurious response, as judged by conventional lung gravimetric and histopathological criteria, but when overt pulmonary edema was preexistent, exercise had a potentiating effect. Changes in lavageable protein were assessed as a more sensitive indicator of permeability changes that may occur during the latency period following PFIB exposure, and the study examined how exercise performed early during the latency period affects this index of pulmonary edema. The study also assessed whether PFIB-induced damage to lung cells is enhanced by exercise during the latency period by measuring lavageable lactate dehydrogenase activity. The results from these latter experiments suggest that a preexisting enhancement in lung permeability is not an absolute requirement for exercise to potentiate the pulmonary edematous response in lungs that are undergoing insidious injury, and that postexposure exercise does not enhance the cell-killing effects of PFIB as a mechanism underlying the exercise potentiating response. Conceivably, the ability of exercise to increase lavageable protein in the absence of a preexisting increase in lung permeability may be due to hyperventilation- and/or pulmonary hypertension-associated intercellular junctional changes that may occur during exercise. Additionally, it remains possible that exercise during PFIB-induced insideous lung injury results in an enhancement in the rate of transcellular transport of blood proteins onto the alveolar surface.

AN - 77188821; 7897273 AB - This review briefly traces the historical developments of proton radiobiology, radiosurgery and radiotherapy for the benefit of young researchers and clinicians entering into this field. In preparing to use protons in radiosurgery and radiotherapy, radiobiological effects of protons were studied extensively by various groups, including the University of California at Berkeley, the University of Uppsala, Massachusetts General Hospital, and the Harvard Cyclotron Laboratory. Considerable work on proton radiobiology was also done because protons are a major component of the radiation environment in space. The biological effects of proton beams were found to be quantitatively and qualitatively similar to conventional radiations used in radiotherapy. The relative biological effectiveness (RBE) of protons suitable for large-field radiotherapy, compared with 60Co gamma-rays, is generally in the range 1.0-1.25, and remains the same with depth of penetration, except for the descending portion of the depth-dose curve. Also, unlike other heavier charged particles and neutrons, the RBE of high-energy protons, which are suitable for large-field radiotherapy, compared with 60Co gamma-rays, is generally found to be independent of the fraction size in in vivo experiments. The oxygen enhancement ratio for high-energy protons is not significantly different from that of X-rays. An RBE = 1.1, compared with 60Co gamma-rays, is generally used in the clinical application of protons; however, the radiobiological data on mouse, rat, rabbit and primate suggest that the gastrointestinal tissues may be relatively more sensitive to protons. About 13,000 patients have been treated with protons at about 15 facilities around the world. Nearly half of these patients were neurosurgical patients treated with stereotactic radiosurgery. The pioneering efforts at the Harvard Cyclotron in collaboration with the Massachusetts General Hospital and the Massachusetts Eye and Ear Infirmary were responsible for the development of proton treatment for choroidal melanoma and for the tumours of the skull base and spine. There has been extensive confirmation of these results by other groups, especially the groups at Lawrence Berkeley Laboratory and Paul Scherrer Institute. The first medically dedicated proton facility is in operation at Loma Linda University in California. The construction in the USA of another proton treatment facility at Massachusetts General Hospital has been decided upon, and there are plans for many more worldwide.

The authors participated in cooperative collaborations with University of California (UC), Berkeley, the Yucca Mountain Project, the Underground Test Area Operable Unit, and other participating organizations within the Hydrologic Resources Management Program (HRMP). They provided operational support to the Nevada Test Site (NTS) organizations by testing a water-evaporation system, championing the use of high-sensitivity logging equipment during drillbacks, and participating in the planning and execution of drilling operations at two nuclear test sites. Los Alamos personnel cooperated in preparing a proposal to drill beside and under a nuclear test located in unsaturated media. The authors gave assistance in laboratory work related to colloid migration and actinide sorption. In conjunction with personnel from the Lawrence Livermore Laboratory, they collected water samples from 10 wells at the NTS that are known to contain radionuclides. Their analyses of these samples suggest that radionuclides may not be moving away from cavity zones at appreciable rates. Recent field sampling shows clearly the need to purge wells of materials introduced during drilling and illustrates the inconsistency between water samples taken by bailing and those taken by pumping.

Chemically buoyant plumes are modeled, in order to compare to previously reported laboratory tank experiments. The plume is generated near the bottom of the box and rises and forms a mushroom-head with some entrainment of surrounding fluid. The head flattens at a considerable depth beneath the ridge before rising to the surface. Once the plume reaches the surface the head is quickly divided by the diverging plates, and the waist width is found to have reached a steady-state value, W. The results show that W is proportional to the square root of the volumetric flux of the plume divided by the diverging plate speed, which is consistent with previously reported experimental data. Our scaling law gives an independent method for estimating the volumetric flux of mantle plumes. The calculated plume fluxes are two to four times larger than previous estimates. If plume buoyancy is purely of thermal origin, then excess temperatures can be estimated from the fluxes. For Iceland, Azores and the Galapagos, the calculated excess temperatures are 140, 57, and 51 degrees C respectively, in agreement with recent, independent estimates from modeling of gravity and bathymetry.

Results thus far show a systematic discordance in that (super 14) C-based ages are generally one to two orders of magnitude younger than (super 36) Cl-based ages. This lack of concordance probably arises from one or more of the following reasons: (1) different transport mechanisms, e.g., vapor transport for (super 14) C; (2) different magnitudes and timing of bomb-pulse signals; (3) mixing of waters from different flow paths; and (4) possibly inadequate methods for correcting for the effect of sample contamination by carbon or chlorine from sources other than the infiltrating water. Preliminary numerical simulation results using the FEHMN code suggest that spatial variation in infiltration rates can enhance lateral flow and mixing that leads to discordance in apparent ages depending on the dating technique. Examples are presented to show that disparate radiometric ages are inevitable and to be expected where mixing of waters of markedly different ages occurs.

Synthetic tests show that simulated annealing is able to locate low P-wave velocity zones with reasonable accuracy in space, and recovers almost 70% of the target velocity perturbations. Testing suggests that significant results can be obtained with as few as two stations. Inversion of ray direction data from Long Valley caldera finds an asymmetrical low velocity zone beneath the resurgent dome at 8km depth, having a perturbation of -25% from the background. This zone extends to the east and south to depths of at least 24km, with a perturbation of about -10%. These features generally agree with previous results from teleseismic travel-time inversion and forward modeling of ray direction, and are probably associated with the residual Long Valley caldera magma chamber.

Instruments were deployed in two 30-km-long profiles, one of 8 and one of 9 stations. These profiles crossed the caldera trending at azimuths of N46 degrees W and N60 degrees E, respectively. Two-dimensional teleseismic relative arrival time inversion of the 1993 data set, supplemented with data from an overlapping 1987 profile, confirms the existence of a mid-crustal low velocity region (-30%) beneath the Valles caldera in the depth range of 8 to 13 km (below sea level), with about a 6 km horizontal extent. This feature is interpreted to be the seismic expression of the remnant magma chamber. A shallow low velocity anomaly beneath San Antonio Mountain coincides with the region of highest thermal gradient values in the caldera. A lower crust/upper mantle low velocity anomaly is imaged but is not as well constrained due to the limited length of the profile. We tentatively correlate this anomaly with the thermal effects of basaltic magmas ponded at the crust-mantle boundary. Copyright 1995 by the American Geophysical Union.

(super 53) Mn activities range 414 to 552 dpm/kg-Fe and increase with depth. Calculated production rates of (super 53) Mn activities range 414 to 552 dpm/kg-Fe and increase with depth. Calculated production rates of (super 53) Mn agree with these measured activities and indicate that the radius of this aubrite (65 cm) was close to that for maximum production rates; no special irradiation conditions are invoked to explain the cosmogenic nuclides in this meteorite.

Pumice fragments in these layers show no evidence for abrasion during lateral transport, unlike pumice in the enclosing deposits, and are well sorted. In most locations they have textural and grain size characteristics typical of Plinian fall deposits. Bedding of these pumice layers ranges from planar with gradual thickness variation over a few meters distance, to highly variable with strong thickening in depressions. The layers are interpreted to record deposition of pumice falling from a Plinian eruption column through laterally moving pyroclastic surges. Depending on the local vigor of the surges during the fallout event, bedding characteristics range from those approaching pure fallout to those approaching pure surge. The simultaneous Plinian and hydrovolcanic, pyroclastic surge-producing activity may have come from two (or more) separate vents, or from a single vent that experienced rapid variations in magma-water interaction.

As information on articulator configurations is not provided during training of the algorithm, only relative positions can be recovered. The procedure quantizes short time windows of a speech signal & uses multidimensional scaling to represent temporally close quantization codes by nearby points in a continuity map. To evaluate the procedure, 30 continuity maps were made by a random-walk technique, using 32 acoustic parameter codes derived from the first three formant center frequencies of acoustic signals produced by an articulatory synthesizer that varied tongue height & fronting. Results show that all maps gave good estimates of relative articulator positions when trained with at least 10 repetitions of each code, accuracy increasing with an increasing number of codes. 6 Figures, 41 References.

AN - 77085833; 7997507 AB - A total of 153 hprt mutants (23 spontaneous, 130 gamma-ray-induced) of primary human skin fibroblasts were isolated and genetic alterations at the locus were studied by multiplex polymerase chain reaction (PCR). The analyses showed that 51% (66/130) of gamma-ray-induced genetic changes were large deletions, whereas the majority of spontaneous mutants (21/23) exhibited point mutations. The spectrum of large genetic alterations appeared to be dependent on dose in gamma-ray-induced (1-4 Gy) mutations; mutants with complete loss of the hprt locus comprised 21 (3/14) or 39% (15/38) of clones isolated after irradiation with 1 or 4 Gy, respectively. The frequency of partial deletions was found to be higher in the mutants isolated from clones irradiated with 2 Gy (38%) than from those irradiated with 4 Gy (8%).

In 3-D problems, computational efficiency becomes important. Finite-difference solutions of the eikonal equation provide computationally efficient methods for generating the traveltime information. Here, a novel finite-difference method for computing the first arrival traveltime by solving the eikonal equation has been developed in Cartesian coordinates. The method, which is unconditionally stable and computationally efficient, can handle instabilities due to caustics and provide information about head waves. The comparison of finite-difference solutions of the acoustic wave equation with the traveltime solutions from the eikonal equation in various structure models demonstrate that the method developed here can provide correct first arrival traveltime information even in areas of complex velocity structure.

The 2D algorithm published by Vinje, et al., 1993, has been extended to 3D to compute wavefronts in complicated inhomogeneous media. The 3D wavefront construction algorithm provides many advantages over conventional ray tracing and other methods of computing travel times in 3D. The algorithm dynamically maintains a reasonably consistent ray density without making a priori guesses at the number of rays to shoot. The determination of caustics in 3D is a straight forward geometric procedure. The wavefront algorithm also enables the computation of multi-valued travel time surfaces.

The minimum hole-diameter requirement for the installation of borehole seismic sensors. The minimum hole-diameter requirement for the installation of borehole seismic sensors. The minimum hole-diameter requirement for the installation of borehole seismic sensors and associated electronics, is compatible with holes of greatly reduced size in comparison with typical wells drilled for the purpose of producing fields. Reduction in hole size makes possible a corresponding decrease in the cost of drilling. Increased use of instrumented boreholes for rock mass characterization can be expected in the future as cost reductions are achieved. Wells dedicated to instrumentation and rock mass interrogation also promise a significantly reduced earth-noise environment and optimum anchoring for seismic monitoring instrumentation.

Report (1) presents the description of physical models and calculation techniques which were chosen by VNIIEF to accomplish this task. These techniques were analysed for their capabilities, the areas of their application were defined, modifications within contract 006 were described, the results of test and methodical calculations were presented. Moreover, the experimental data were analyzed over the source parameters and contamination measurements which can be used in the comparison with the calculation results. Based on these data, this report compares the calculation results obtained with VNIIEF calculation techniques with the LANL-presented experimental results. The calculations which statements and results are given in section 1, included the following processes: explosion cloud ascent dynamics and jet release origin; aerosols kinetics in the release source including composite particle origin in the explosion cloud caused by radioactive substance sorption an the soil particles; contaminant transport in atmosphere and their in-site fallout due to the accidental explosions and fires; and atmospheric flow dynamics and industrial contamination transfer over the complicated terrain.

Beginning on 29 November 1989, a 15 square km region near Bernardo, NM, produced the strongest and longest lasting sequence of earthquakes in the rift in 54 years. Our research focuses on the Bernardo swarm which occurred 40 km north of Socorro, New Mexico in the axial region of the central Rio Grande rift. Important characteristics concerning hypocenters, fault mechanisms, and seismogenic zones are discussed.

This report documents that monitoring. Based on this survey, there is no reason for concern about significant contamination in the parking area as a whole, although unexpected small hot spots could exist between the grid points where monitoring was performed. However, the grouping of high readings on the east side of the parking area does point to possible contamination at the level of 100 dpm/100 sq cm or less (above background). Further monitoring or remediation of this area seems appropriate. In addition, because this was an alpha survey, one cannot rule out contamination under the asphalt or possibly between layers if it was paved more than once.

The methodology assumes continuous exposure water contaminated with species (i) at the accessible environment (i.e., just beyond the geologic barrier afforded by the geologic repository). The dose integration is performed out to a reference post-release time. The integrated dose is a function of the total initial inventory of radionuclide (i) the repository, the time at which complete and instantaneous failure of the engineered barrier (e.g., waste canister) in a geologic repository occurs, the fractional dissolution rate (from waste solid form) of radionuclide (i) in ground water, the ground water travel time to the accessible environment, the retardation factor (sorption on the geologic media) for radionuclide i, the time after radionuclide begins to enter the biosphere. In order to assess relative dose, the ratio of total integrated dose to that for a reference LLFP species (j) (e.g., Tc-99) was defined. This ratio is a measure of the relative benefit of transmutation of other LLFPs compared to Tc-99. This methodology was further developed in order to quantify the integrated dose reduction per neutron utilized for LLFP transmutation in accelerator-driven transmutation technologies (ADTT). This measure of effectiveness is a function of the integrated dose due to LLFP species (i), the number of total captures in LLFP species (i) chain per LLFP nuclide fed to the chain at equilibrium, and the number of total captures in related transmutation product (TP) chains per capture in the LLFP species (i) chain. To assess relative transmutation effectiveness, the ratio of integrated dose reduction per neutron utilization to that for a reference LLFP species (j) (e.g., Tc-99) was defined. This relative measure of effectiveness was evaluated using the LLFP transmutation strategy.

The rock fractures to be used have natural fractures or artificial fractures with engineered heterogeneity. These tracer experiments will provide data with well-defined geometry and conditions for use in code validation. The experiments also provide an experimental framework to test inverse methods. Results are presented for a series of migration experiments using conservative tracers in artificial fractures with near parallel plane and near wedge-shaped fractures. The results are compared with those predicted with transport code TRACR3D. The fracture is treated as an equivalent porous medium with a "cubic law" permeability and a porosity that is proportional to the aperture. The results show good agreement, both between experimental results and those predicted by TRACR3D, but also between the distribution of the dye tracer in the fracture and the elution profiles. This suggests that the transport of a tracer through a fracture can be inferred from elution profiles.

Among the facilities affected by these developments is Los Alamos National Laboratory (LANL) in New Mexico. RCRA, as amended by the Hazardous and Solid Waste Amendments (HSWA) in 1984, requires all facilities which involve the treatment, storage, and disposal of hazardous waste obtain a RCRA/HSWA waste facility permit. LANL complied with CEARP by initiating a process of identifying potential release sites associated with LANL operations prior to filing a RCRA/HSWA permit application. In the process of preparing the RCRA/HSWA waste facility permit application to the U.S. Environmental Protection Agency (EPA), a total of 603 Solid Waste Management Units (SWMUs) were identified as part of the requirements of the HSWA Module VIH permit requirements. The HSWA Module VIII permit requires LANL to determine whether there have been any releases of hazardous waste or hazardous constituents from SWMUs at the facility dating from the 1940's by performing a RCRA Facility Investigation to address known or suspected releases from specified SWMUs to affected media (i.e. soil, groundwater, surface water, and air). Among the most troublesome of the potential releases sites are those associated with airborne radioactive releases. In order to assess health risks associated with radioactive contaminants in a manner consistent with exposure standards currently in place, the DOE and LANL have established Screening Action Levels (SALs) for radioactive soil contamination. The SALs for each radionuclide in soil are derived from calculations based on a residential scenario in which individuals are exposed to contaminated soil via inhalation and ingestion as well as external exposure to gamma emitters in the soil. The applicable SALs are shown.

The general consensus was that some type of convective motion edits in the Earth's liquid iron alloy core that is affected by rotational forces in a way that continually generates new magnetic field to replace that which diffuses away. Magnetic-field reversals and secular variation have long been measured but no theory existed to explain these phenomena. To gain an understanding of the basic physical mechanisms of the "geodynamo", we produced the first self-consistent computer simulation of convection and magnetic field generation in a rotating three-dimensional spherical fluid shell as an anologue to the Earth's convective dynamo. This is a final report of a three-year Laboratory-Directed Research and Development (LDRD) project at the Los Alamos National Laboratory (LANL).

The vadose zone beneath an active disposal unit (DU 37), was accessed by utilizing low-impact, air-rotary horizontal drilling technology. Core samples were pulled, via wire-line core method, in 3 horizontal holes fanning out below DU 37 at approximately 5 foot intervals depending on recovery percentage. Samples were surveyed and prepared in-field following Environmental Restoration (ER) guidelines. Samples were transferred from the field to the CST-9 Radvan for initial radiological screening. Following screening, samples were delivered to CST-3 analytical lab for analyses including moisture content, 23 inorganics, 60 volatile organic compounds (VOC's), 68 semivolatile organic compounds (SVOC's), tritium, lead 210, radium 226 & 228, cesium 137, isotopic plutonium, americium 241, strontium 90, isotopic uranium, and isotopic thorium. Other analyses included matric potential, alpha spectroscopy, gamma spectroscopy, and gross alpha/beta. The overall results of the analysis identified only tritium as having migrated from the DU. Am-241, Eu-152, and Pu-238 were possibly identified above background but the results are not definitive. Of all organics analysed for, only ethyl acetate was tentatively identified slightly above background. All inorganics were found to be well below regulatory limits. Based on the results of the above mentioned analyses, it was determined that Area G's disposal units are performing well and no significant liquid phase migration of contaminants has occurred.

Our approach is to combine the results of conventional analysis of field data from explosions and earthquakes with results of numerical models of actual and idealized situations. Existing first-principles, finite difference codes allow us to examine source effects in the non-linear regime; linking the results of these near-source calculations to finite difference, anelastic wave propagation codes allows us to examine the effect of various source region and propagation path characteristics on signals observed at regional distances. An investigation of discriminant differences for the DIVIDER and CORREO underground nuclear explosions is provided as an example of the approach used.

Strong shear motion is observed which can not be accounted for by the simple explosion source. Spall (the detachment and slap-down of the near surface strata and the separation of the burden and overburden from the continuum) accompanying the explosion seems to play an important role in shear wave energy generation.

We have begun our analysis using data from the station WMQ of the Chinese Digital Seismic Network (CDSN). Regional seismograms are being analyzed to construct travel time curves, velocity models, attenuation characteristics, and to quantify regional propagation effects such as phase blockages. Using locations from the USGS Preliminary Determination of Epicenters (PDE), we have identified Pn, Pg, Sn, and Lg phases, constructed travel time curves, and estimated apparent velocities using linear regression. Surface wave group velocities will be measured and inverted for regional structure. Preliminary noise spectra for WMQ have been obtained from the IRIS DMC. Chinese seismicity catalogs from the USGS and SSB are being used to identify and obtain seismic data (including mine seismicity) and information for lower magnitude events. We have identified the locations of nearly 500 mines in China for inclusion in the knowledge base.

Development of these physical models can also be used in conjunction with the ground motion data as diagnostics of blasting efficiency. In order to properly address the multi-dimensional aspect of data sets designed to constrain these sources, we are investigating a number of modem visualization tools that have only recently become available with new, high-speed graphical computers that can utilize relatively large data sets.

The mixed waste samples investigated include vitrified waste glass and contaminated soil. Compared to traditional analysis techniques, the laser-based method is fast (i.e., analysis times on the order of minutes) and essentially waste free since little or no sample preparation is required. Detection limits on the order of pmm Sr were determined.

The remote location in the southwestern United States was ideal for such a project. After the war, research activities continued at the Los Alamos installation, focusing on new nuclear weapons models as well as greater effectiveness and reliability of existing weapons. Due to the emphasis on nuclear and non-nuclear weapons development as well as associated nuclear research, a large inventory of radionuclides and heavy metals have been tested, expended, and disposed of in the local environment, a high plateau of tuffaceous volcanic rocks incised by deep canyons in a semi-arid climate. In recent years an intensive evaluation of the environmental, impact of weapons testing at Los Alamos and elsewhere has been undertaken. GIS system utilization and image processing of past and current data has been an important part of this evaluation. Important problems can be more easily displayed and understood using this methodology. The main objective in this paper is to illustrate how transport of depleted uranium and associated heavy metals (copper in this case) used in dynamic testing of weapons components at open air firing sites can be evaluated and visualized. In our studies, surface water has been found to be the predominant transport mechanism. We have sampled soils, sediments, fallout, runoff water and snowmelt over a number of years in order to understand contaminant transport on- and offsite. Statistical analyses of these data have assisted in our characterization of issues such as contaminant variability, spatially and temporally, as well as in development of transport rates.

These monitors operate by detecting the ions created by alpha particles interacting with ambient air. Thus, detection is not limited by the short range of the alpha particle and no window is required between the contamination and the detection region. These properties make LRAD-based detectors ideal for operation in field environments where complex objects to be monitored are the norm and reliability is crucial. Three monitors of particular interest in D&D operations are the building surface monitor, the internal volume monitor for use on the inner surfaces of pipes, ducts, and tanks, and the conveyer belt monitor for concrete rubble and structural steel. Surface monitors have been used extensively, both in laboratory and field environments, internal volume monitors have been tested in the laboratory, and the conveyer system is still a conceptual design. These monitors and related applications demonstrate the utility of LRAD-based monitors for D&D operations as well as exploring some of the new ways that fieldable monitoring systems can be used for D&D. Ion collection sensing technology can be used to solve many of the alpha detection problems unique to the D&D field.

Their main concerns are contamination of water, soil and air as well as the hazardous and radioactive wastes stored at the Laboratory site. Environmental surveillance results show that contamination may have migrated off-site through the canyons of the Pajarito Plateau to the Rio Grande. San Ildefonso Pueblo and Cochiti Pueblo are located downstream from the canyons that drain the Los Alamos town site and Laboratory lands. Several other pueblos are also located downstream from the Laboratory. The Pueblos located upstream from the laboratory indicated that contamination of air and worry about the contamination of the animals they hunt for food is a more important concern to them. There are many canyons that drain the areas where Los Alamos and Laboratory property are located. To be able to characterize those canyons that are known or suspected to have received contamination, the ER Project needs to prepare RCRA Facility Investigation (RFI) work plans for approval by the Environmental Protection Agency (EPA). Once EPA approves the work plant, characterization activities can start for the specific areas identified in the work plan.

The use of biological methods for remediation of high explosives contamination has received considerable attention in recent years. Biodegradation is most easily studied using organisms in liquid cultures. Thus, the amount of explosive that can be degraded in liquid culture is quite small. However, these experiments are useful for gathering basic information about the biochemical pathways of biodegradation, identifying appropriate organisms and obtaining rates of degradation. The authors' laboratory has investigated all three major areas of explosives bioremediation: explosives in solution, explosives in soil, and the disposal of bulk explosives from demilitarization operations. They investigated the three explosives most commonly used in modern high explosive formulations: 2,4,6-trinitrotoluene (TNT), hexahydro 1,3,5-trinitro-1,3,5-triazine (RDX) and octahydro-1,3,5,7-tetranitro- 1,3,5,7-tetrazocine (HMX).

As a result of the Laboratory's activities, contamination of the environment occurred. The cleanup of contaminated areas and the prevention of further contamination has become an important part of the Laboratory's new mission: the reduction of the nuclear danger. The cleanup of the Laboratory is somewhat unique. It is a very large site. It includes 43 square miles of Laboratory land that will continue to be in industrial use or under institutional control for decades or centuries to come. It also includes about 25 square miles of former Laboratory land that has been converted to residential use, the Los Alamos townsite. The unusual topography and hydrogeology of the site was shaped during the last million years through the eruption of a huge volcano and the ensuing erosion of the tuff-basalt plateau into 19 canyons and associated finger-like mesas. During the early phase of the Environmental Restoration (ER) Program, 2,100 sites were identified as potential release sites. Sites range from a few hundred square feet to a few acres in area. Contamination depths range from a few to 100 feet. Typical contaminants are chemicals, heavy metals, radioactive constituents, and high explosives. Of greatest concern are surface contamination, migration of the contaminants along the surface into creeks and arroyos of the canyons and ultimately into the Rio Grande, and migration through the earth into the drinking water aquifers.

Soil samples taken from specific locations at this detonator facility were analyzed for harmful metals and screened for explosives. A sanitary outflow, a burn pit, a pentaerythritol tetranitrate (PETN) production outflow field, an active firing chamber, an inactive firing chamber, and a leach field were sampled. Energy dispersive x-ray fluorescence (EDXRF) was used to obtain semi-quantitative concentrations of metals in the soil. Two field spot-test kits for explosives were used to assess the presence of energetic materials in the soil and in items found at the areas tested. PETN is the major explosive in detonators manufactured and destroyed at Los Alamos.

These investigations show that soils exhibiting diverse morphologic character, varying ages, and relations to landforms characterize these sites. A review of recent and ongoing soils studies also shows that soil textural, chemical, and mineralogical characteristics may profoundly influence the migration and/or retardation of a variety of potential contaminants initially placed in direct contact with soils, or that encounter soils during subsurface percolation or discharge. Soil-geomorphic relations also provide important insights into recent site erosion, deposition or other surficial processes that must, be considered as part of environmental assessment of a given site and remediation; and, the planned geomorphic mapping activities at each site, as well as other associated activities (e.g, geophysical survey, site sampling) are accordingly appropriate and necessary with respect to identification of significant soil relations at each site. Specific and general recommendations in consideration of important findings regarding the possible impacts of soil development of the nature of contaminant behavior at various sites are provided to help guide sampling and analysis activities during ERP investigations outlined in the RFI Work Plan for Operational Unit-1071.

From chemical shift and intensity measurements of complexed species, NMR can serve as a species-specific structural probe for molecules in solution and can be used to validate thermodynamic constants used in geochemical modeling. Fourier-transform nuclear magnetic resonance (FT-NMR) spectroscopy has been employed to study the speciation of uranium(VI) ions in aqueous carbonate solutions as a function of pH, ionic strength, carbonate concentration, uranium concentration, and temperature. Carbon-13 and oxygen-17 NMR spectroscopy were used to monitor the fractions, and hence thermodynamic binding constants of two different uranyl species UO (sub 2) (CO (sub 3) )( (sub 3) ) ( (super 4-) ) and (UO (sub 2) ( (sub 3) )(CO (sub 3) )( (sub 6) )( (super 6-) ) in aqueous solution. Synthetic buffer solutions were prepared under the ionic strength conditions used in the NMR studies in order to obtain an accurate measure of the hydrogen ion concentration, and a discussion of pH = -log(a (sub H) (super +) ) versus p(H) = -log(H+) is provided. It is shown that for quantitative studies, the quantity p(H) needs to be used. Fourteen uranium(VI) binding constants recommended by the OECD NEA literature review were corrected to the ionic strengths employed in the NMR study using specific ion interaction theory (SIT), and the predicted species distributions were compared with the actual species observed by multinuclear NMR. Agreement between observed and predicted stability fields is excellent. This establishes the utility of multinuclear NMR as a species-specific tool for the study of the actinide carbonate complexation constants, and serves as a means for validating the recommendations provided by the OECD NEA.

As a sample progresses through sample preparation to sample analysis and finally to data interpretation, increasing expertise and judgment are needed at each step. The Data Interpretation Module (DIM) echoes the automation's plug-and-play philosophy as a reusable engine and architecture for handling both the uncertainty and knowledge required for interpreting contaminant sample data. This presentation describes the implementation and performance of the DIM in interpreting polychlorinated biphenyl (PCB) gas chromatogram and shows the DIM architecture's reusability for other applications.

The Paleozoic and Mesozoic units have been thinned and removed during Laramide uplift in an area now obscured by the younger rift basin. The Espanola basin is generally a shallow, asymmetric transitional structure between deeper, better developed basins to the northeast and southwest. The gravity data indicate the presence of three narrow but deep structural lows arrayed along the Embudo/Pajarito fault system. These sub-basins seem to be younger than the faults on the basin margins. This apparent focussing of deformation in the later history of the basin may be a response to changes in regional stress or more local accommodation of the rift extension. Future work is planned to develop seismic data over one of these sub-basins, the Velarde graben, and to better define the gravity map in order to facilitate three-dimensional modeling.

Extended periods of high flow on drainages that carried pluvial and glacial runoff probably produced middle and late Quaternary incision. The Bandelier Tuff (1.6 and 1.2 Ma), Lava Creek B ash (0.62 Ma) and the El Cajete pumice (50-60 ka) provide local age control, supplemented by ages estimated from amino-acid ratios in gastropods and by (super 14) C ages. The Pajarito, Rendija Canyon and Guaje Mountain faults displace Pleistocene deposits; the latter faults were probably active in the Holocene. The NE-trending Embudo fault zone has been the northern structural margin of the Espanola Basin since middle Miocene time, but it is difficult to demonstrate Quaternary slip along the zone. Quaternary fluvial deposits consist of axial-channel gravels and thin overbank deposits covered by coarse sand and gravel delivered by ancestral alluvial fans. Sequences of lithologically similar deposits are preserved at heights from more than 170 m to 15 m above the modern floodplain between Abiquiu and Otowi Bridge. These sequences suggest that alluvial fans expand across the Rio Grande floodplain during transitions from pluvial to interpluvial climate and that deposits are preserved when the river cuts down during the next pluvial period. Holocene cut-and-fill sequences are preserved along some tributaries to the Rio Grande, but their climatic significance is uncertain. Incision along the Rio Grande in upper White Rock Canyon generated massive slumps beginning in middle Pleistocene time as the river cut through weak rocks of the Santa Fe Group, the Puye Formation and Pliocene lacustrine deposits. Reactivation of toe areas of some slumps dammed the Rio Grande at >43 ka and at least four times between 18 and 12 ka, producing lakes as deep as 60 m. Landslide motion and lake age in White Rock Canyon coincide with the glacial maximum and final pluvial pulses of the latest Pleistocene, suggesting that climate change destabilized older slumps through toe incision or by greater pore pressures from increased groundwater recharge. The Rio Grande flowed at its modem grade before about 12 ka. JF - Guidebook - New Mexico Geological Society AU - Dethier, David P AU - Reneau, Steven L A2 - Bauer, Paul W. A2 - Kues, Barry S.

Re-analysis of data for earthquakes between 1973 and 1988 and new analysis for earthquakes between 1989 and 1994 have provided a set of earthquake locations that are more accurate than previously available. Newly determined epicenters of about 580 events show that earthquakes occur in widely scattered locations through much of the area, although some occur in clusters and some are associated with fault zones. This level of detail has not been seen previously on earlier epicenter maps. Previous studies had concluded that the margins of the Rio Grande rift can not be identified from the seismicity and the new locations confirm that. The areas of greatest seismicity all lie in a roughly horseshoe-shaped zone of activity that surrounds the relatively inactive Valles Caldera and Jemez Mountains. The tectonics of this region would be better understood with additional information from the earthquakes, such as focal mechanisms.

This small part of the rift, (170 km (super 2) area), has extended at least 5% in a general E-W direction since 1.2 Ma. Extension has been accommodated on five major N-trending fault zones composed of NW- to NE-striking, high-angle normal faults that terminate in diffuse fracture zones. Faults are concave toward the hanging wall, which is preferentially dissected by minor synthetic and antithetic splays. At the western margin of the basin, two faults show down-to-the-west motion with displacement of Quaternary rocks increasing toward the south to a maximum of 34 m. East, toward the basin center, two faults show down-to-the-east motion with displacement of Quaternary rocks increasing toward the north to a maximum of 37 m. Therefore, from west to east, the faults have opposing dips, concavity, displacement gradients and sense of motion, suggesting that deformation is roughly symmetrically and homogeneously distributed across the area. This movement history, combined with microseismic activity on basin-center faults and ages of faulted and unfaulted Holocene sediments, suggests that (1) faults formed in response to approximately E- to NE-directed extension in the past 1.2 Ma; (2) faulting within the basin could be advancing toward the basin center; and (3) total extension across this part of the Espanola Basin has been 5% since 1.2 Ma.

The principal contaminant at the Savannah River Integrated Demonstration is tricloroethylene (TCE) a volatile organic compound (VOC). A 384-day test run at Savannah River, sponsored by the US Department of Energy (DOE), Office of Technology Development (EM-50), furnished information about the performance and applications of ISBR. In situ bioremediation, as tested, is based on two distinct processes occurring simultaneously: the physical process of in situ air stripping and the biological process of bioremediation. Both processes have the potential to remediate some amount of contamination. A quantity of VOCs, directly measured from the extracted airstream, was removed from the test area by the physical process of air stripping. The biological process is difficult to examine. However, the results of several tests performed at the SRID and independent numerical modeling determined that the biological process remediated an additional 40% above the physical process. Given these data, the cost effectiveness of this new technology can be evaluated.

Because the transient dynamic stresses induced at regional distances by the Landers surface waves are much larger than the expected static stresses, the magnitude and the characteristics of the dynamic stresses may bear upon the earthquake triggering mechanism. The Landers earthquake was recorded on the UPSAR (U.S. Geological Survey Parkfield Small Aperture Array) array, a group of 14 triaxial accelerometers located within a 1-square-km region 10 km southwest of the town of Parkfield, California, 412 km northwest of the Landers epicenter. No triggered earthquakes were observed at Parkfield. Multiple filter analysis shows that the displacements, obtained by double integration, are dominated by the fundamental mode Love and Rayleigh modes, with some higher-mode contributions for periods shorter than 10 s. Most of the surface waves propagated along the great circle path from Landers, but a late arriving surface wave appears to have been scattered from the Sierra Nevada Mountains. We used a standard geodetic inversion procedure to determine the surface strain and stress tensors as functions of time from the observed displacements. Peak dynamic strains and stresses at Earth's surface are about 7 mu strain and 0.035 MPa, respectively, and they have a flat amplitude spectrum between 2-s and 15-s period. These stresses agree well with stresses predicted from a simple equation using the ground velocity spectrum observed at a single station. Peak stresses ranged from about 0.035 MPa at the surface to about 0.12 MPa between 2 and 14 km depth, with the sharp increase of stress away from the surface resulting from the rapid increase of rigidity with depth and from the influence of mode shapes. Because of the free-surface boundary conditions, the horizontal components of the stress tensor tend to dominate in the top 5-6 km of the crust, which might cause triggered seismicity to have strike-slip or normal mechanisms. Comparison of dynamic stresses induced by the Landers, Loma Prieta, and Petrolia earthquakes at a variety of sites indicates that the Landers stresses were not spectacularly larger than those induced by the other sources. Landers dynamic stresses were comparable to Coalinga static stresses at Parkfield. The effective strain caused by Landers at Parkfield, where no earthquakes were triggered, are the same amplitude as those at some sites in Nevada where earthquakes were triggered. Comparing various authors' observations of dynamic stresses, there is no obvious characteristic of these stresses that correlates with the triggered seismicity.

Because a finitely conducting inner core has a diffusive timescale of its own of a few thousand years, which is long compared with the most rapid advective timescales possible in the outer core, the field in the inner core must necessarily average over these very rapid timescales. This averaging-out may then have a stabilizing influence, preventing the very rapid timescales from dominating the dynamo processes in the outer core. In this work we present a solution to the mean-field geodynamo equations which seems to exhibit these features. In this way it may be possible to reconcile the complicated, time-dependent nature of the field and flow in the dynamically active portion of the outer core with the simple, relatively stable nature of the externally observed dipole component of the Earth's magnetic field.

Epidosite within the graben occurs as massive epidosite (epidosite concentration greater than 80%) and zones of incipient epidotization (between 5% and 80%). Regions of incipient epidotizations are characterized by the juxtaposition of greenschist facies alteration and epidosite; the fluids responsible for each of these alteration styles had similar oxygen isotope compositions and temperatures. Petrographic observations suggest that the epidosite protolith was a previously altered rock. In addition, evidence of secondary porosity is found in the areas of incipient epidotization, suggesting that the reactions creating epidosite lead to the creation of porosity. Computer simulated fluid-rock interaction at 350 degrees C and 500 bar between a Ca-rich, seawater-derived hydrothermal fluid and a greenschist facies mineral assemblage (36% albite, 36% quartz, 18% chlorite, 6% magnetite, 3% clinopyroxene, and 1% epidote) produced an epidosite assemblage (epidote + quartz + chlorite + hematite/magnetite) at fluid/rock mass ratios of 1250:1 to 50:1. The results suggest that reaction of this hydrothermal solution with albite and chlorite, as opposed to fresh diabase, controls epidosite formation. The calculations also indicate initial reduction in rock volume, which correlates with the observed porosity in incipiently epidotized rocks of the Solea graben. We suggest that hydrothermal circulation related to the localized intrusion of high-level gabbro in highly attenuated crust resulted in the transformation of green-schist facies rocks to epidosite. This is consistent with evidence from the Mid-Atlantic Ridge at the Kane Fracture Zone for reaction between upflowing hydrothermal solutions and previously altered basalt.

Two isolates, identified as Morganella morganii and Providencia rettgeri, completely transformed both RDX and the nitroso-RDX reduction intermediates. The third isolate, identified as Citrobacter freundii, partially transformed RDX and generated high concentrations of nitroso-RDX intermediates. All three isolates produced 14CO2 from labeled RDX under O2-depleted culture conditions. While all three isolates transformed HMX, only M. morganii transformed HMX in the presence of RDX.

AN - 76816764; 7960779 AB - A cohort mortality study was conducted of 15,727 white men employed by the Los Alamos National Laboratory, a nuclear research and development facility. Some of the workers at this facility have been exposed to various forms of ionizing radiation and other potentially hazardous materials. These analyses focused on whole-body ionizing radiation exposures and internal depositions of plutonium. The results indicated that overall mortality among this cohort is quite low, even after nearly 30 y of follow-up. No cause of death was significantly elevated among plutonium-exposed workers when compared with their unexposed coworkers; however, a rate ratio for lung cancer of 1.78 (95% CI = 0.79-3.99) was observed. A case of osteogenic sarcoma, a type of cancer related to plutonium exposure in animal studies, was also observed. Dose-response relationships for whole-body dose from external ionizing radiation and tritium were observed for cancers of the brain/central nervous system, the esophagus, and Hodgkin's disease.

The Landers earthquake was recorded on the UPSAR array, a group of 14 triaxial accelerometers located within a 1-square-km region 10 km southwest of the town of Parkfield, California, 412 km northwest of the Landers epicenter. We used a standard geodetic inversion procedure to determine the surface strain and stress tensors as functions of time from the observed dynamic displacements. Peak dynamic strains and stresses at the Earth's surface are about 7 microstrain and 0.035 MPa, respectively, and they have a flat amplitude spectrum between 2 s and 15 s period. These stresses agree well with stresses predicted from a simple rule of thumb based upon the ground velocity spectrum observed at a single station. Peak stresses ranged from about 0.035 MPa at the surface to about 0.12 MPa between 2 and 14 km depth, with the sharp increase of stress away from the surface resulting from the rapid increase of rigidity with depth and from the influence of surface wave mode shapes. Comparison of Landers-induced static and dynamic stresses at the hypocenter of the Big Bear aftershock provides a clear example that faults are stronger on time scales of tens of seconds than on time scales of hours or longer.

Air-coring technology allows sampling of subsurface lithology with minimal perturbation to ambient characteristic such as that required for exploratory holes near aquifers, environmental applications, and site characterization work. Two horizontal holes were cored, one 50 ft long and the other 150 ft long, in densely welded fractured tuff to simulate the difficult drilling conditions anticipated at Yucca Mountain. Drilling data from seven holes on three other prototype tests in nonwelded tuff were also collected for comparison. The test was used to establish preliminary standards of performance for drilling and dust collection equipment and to assess procedural efficiencies. The Longyear-38 drill achieved 97% recovery for HQ-size core (-2.5 in.), and the Atlas Copco dust collector (DCT-90) captured 1500 lb of fugitive dust in a mine environment with only minor modifications. Average hole production rates were 6-8 ft per 6-h shift in welded tuff and almost 20 ft per shift on deeper holes in nonwelded tuff. Lexan liners were successfully used to encapsulate core samples during the coring process and protect core properties effectively. The Prototype Air-Coring Test demonstrated that horizontal air coring in fractured welded tuff (to at least 150 ft) can be safely accomplished by proper selection, integration, and minor modification of standard drilling equipment, using appropriate procedures and engineering controls. The test also indicated that rig logistics, equipment, and methods need improvement before attempting a large-scale dry drilling program at Yucca Mountain.

Hot springs and fumaroles are surface manifestations of a hydrothermal reservoir (210 degrees -300 degrees C; 2-10 X 10 (super 3) mg/kg Cl) that is most extensive in fractured, caldera fill tuffs and associated sedimentary rocks, located in specific structural zones. Fluids are composed of deeply circulating water of (primarily) meteoric origin that have a mean residence time in the reservoir of 3 to 10 k.y. The only component of clearly magmatic origin is anomalous (super 3) He although it is possible that some magmatic water, carbon, and sulfur is contributed to present hydrothermal fluids. Host rocks show intense isotopic exchange with hydrothermal fluids. Alteration assemblages are controlled by temperature, permeability, fluid composition, host-rock type, and depth. A generalized distribution from top to bottom of the system consists of argillic, phyllic, propylitic, and calc-silicate assemblages. Typical alteration minerals in phyllic and propylitic zones are quartz, calcite, illite, chlorite, epidote, and pyrite, whereas common vein minerals consist of the above minerals plus fluorite, adularia, and wairakite. Argentiferous pyrite, pyrargyrite, molybdenite, sphalerite, galena, chalcopyrite, arsenopyrite, stibnite, barite, and tetradymite (?) have been found at various depths in the Valles system. Fluid inclusion studies show that these mineral assemblages formed from liquid water (0-5.5 wt % NaCl equiv) at temperatures ranging from 175 degrees to 310 degrees C, depending on location in the system. Fluid inclusion studies also show that the top of the liquid-dominated zone has descended, leaving behind a low-pressure vapor cap. Dating of spring deposits, core samples of vein minerals, and altered host rocks by K-Ar, U-Th, U-U, and paleomagnetic methods indicates that the hydrothermal system was created at about 1.0 Ma and has been continuously active to the present. However, these dates in combination with geologic and fluid inclusion evidence suggest that the vapor zone formed at about 0.5 Ma, after a breach of the southwest caldera wall drained widespread intracaldera lakes and lowered the hydraulic head on the hydrothermal reservoir. Although petrologic and geophysical evidence indicates that residual pockets of melt still reside in the pluton beneath the caldera, the size of the hydrothermal system has shrunk since initial formation. Thus, the Valles caldera contains a mature hydrothermal system that remains hot, that contains a classic geothermal configuration, and that displays many analogies to epithermal mineral deposits exposed in older volcanic environments.

AN - 50211272; 1994-050961 AB - The northwestern margin of the Espanola basin, part of the Rio Grande rift in northern New Mexico, is characterized by a zone >17 km wide of oblique-slip faults that offset upper Paleozoic and Mesozoic strata of the eastern Colorado Plateau from Eocene and younger sedimentary rocks of the rift. Along this margin, a reasonably complete section of pre- and synrift Tertiary sediments is exposed. Combined interpretations of seismic reflection, seismic refraction, gravity, and geologic data acquired along a profile perpendicular to this boundary define the geometry of faulting, possible rotation of sedimentary units, and stratigraphy of rift fill. Vertical separation on the westernmost major fault, assumed to be the bounding fault between the rift and the Colorado Plateau, is <500 m; separation on other faults in the zone is <200 m. Thus the northwestern part of the Espanola basin ("Abiquiu embayment") is a shallow platform rather than a deep rift basin. The embayment is separated from the main Espanola basin by the east-northeast-striking Embudo transfer fault, which appears to act as the northern bounding fault of the main basin. Although Tertiary units are progressively faulted downward toward the axis of the rift, depth to inferred Precambrian crystalline rocks becomes shallower and the stratigraphic thickness of the intervening Paleozoic and Mesozoic units decreases toward the axis. We interpret pinching out of these units toward the east as erosional thinning on the western flanks of the Laramide-age Sangre de Cristo/Brazos geanticline, which underlay much of the present rift basin. Imprecise age constraints suggest that faulting of the rift margin began 10-7 Ma, but was not active after 7 Ma. Extension was apparently transferred to the Embudo fault zone, which remained active until at least 2.5 Ma and possibly into Quaternary time. The Embudo transfer zone effectively decoupled the Abiquiu embayment from the main Espanola basin. Thus the boundary at Abiquiu preserves an early stage in the formation of the rift boundary. The shift in activity may have resulted from a change in regional stress field, or from increasing magnitude of strain, or both. The change in locus of extension reflects a narrowing of rift basins through time and an integration of main bounding structures between adjacent basins. Although we are uncertain whether the Abiquiu region, which uniquely preserves an early stage of deformation, is representative of other areas of continental extension, our results indicate that the initial formation of rift basins may occur as high-angle, planar normal faults distributed over a broad zone. No evidence from seismic data or from rotation of beds exists to indicate that faults become listric with depth, which is compatible with the small amount of extension (3.5%) inferred at this boundary.

A model of these materials, taking their macroscopic elastic properties to result from many mesoscopic hysteretic elastic units, is developed. The Preisach-Mayergoyz description of hysteretic systems and effective medium theory are combined to find the quasistatic stress-strain equation of state, the quasistatic modulus-stress relationship, and the dynamic modulus-stress relationship. Hysteresis with discrete memory is inherent in all three relationships. The dynamic modulus-stress relationship is characterized and used as input to the equation of motion for nonlinear elastic wave propagation. This equation of motion is examined for one-dimensional propagation using a Green function method. The out-of-phase component of the dynamic modulus due to hysteresis is found to be responsible for the generation of odd harmonics and to determine the amplitude of the nonlinear attenuation.

The results indicate that the bulk chemical composition of meteorites is a major factor influencing the production of cosmogenic nuclides. Numerical simulations using Monte Carlo particle production and transport codes were used to investigate particle fluxes, (super 38) Ar production rates and (super 21) Ne/ (super 22) Ne ratios in the meteorites having a wide range of composition. The results show that enhanced fluxes of low-energy secondary particles in metal-rich phases explain differences in nuclide production in the various meteorite classes.

We present in situ proton-induced X-ray emission (PIXE) microanalytical data for ilmenite (Ilm), orthopyroxene (Opx), pyrrhotite (Po) and coexisting silicic glass in a rhyolite lava from Clear Lake, California. The rhyolite contains grains of Ilm (X (sub ilm) = 0.96-1.00) associated with Opx and Plag phenocrysts. Po occurs as inclusions in Ilm and Opx, and as rare single grains. Ilmenite concentrates Nb (D = 51-71), Ta (64-85), Zn (10-11), Mo (>5) and Zr (1.0-1.4). Opx concentrates Ni (D = approximately 11-25) and Zn (14-16). Po concentrates Mo (D = approximately 161), As (2-3), Se ( approximately 36-44), Pb (2), Co ( approximately 999), Cu ( approximately 459-502) and Ni ( approximately 1842) relative to silicic melt, but these coefficients may reflect liquid/liquid rather than solid/liquid partitioning. Ilmenite is the dominant oxide in Clear Lake volcanic rocks, occurring in silicic to intermediate lavas and metasedimentary xenoliths. Silicic volcanic rocks of the area formed by interaction of mafic magmas with deep crustal rocks. The dominance of ilmenite over magnetite reflects the bulk composition and low f (sub O2) of a metasedimentary source component. The relative abundance of ilmenite in such systems and its high D (sub Nb) - and D (sub Ta) -values suggest that it will strongly influence Nb and Ta concentrations during partial melting of crustal rocks and during crystal fractionation. Similarly Po will exert an important influence on the distribution of chalcophile and siderophile elements. Ilm and Po must be considered in quantitative fractionation models involving HFSE and metals, even if present in trace abundances.

The viscous component of deformation has an effective viscosity that depends exponentially on the inverse absolute temperature and nonlinearly on the shear stress; the elastic deformation is linear. Crustal thickness and temperature are constrained by seismic and heat flow data for California. The models are for anti plane strain in a 25-km-thick crustal layer having a very long, vertical strike-slip fault; the crustal block extends 250 km to either side of the fault. During the earthquake cycle that lasts 160 years, a constant plate velocity nu (sub p ) /2 = 17.5 mm yr (super -1) is applied to the base of the crust and to the vertical end of the crustal block 250 km away from the fault. The upper half of the fault is locked during the interseismic period, while its lower half slips at the constant plate velocity. The locked part of the fault is moved abruptly 2.8 m every 160 years to simulate great earthquakes. The results are sensitive to crustal rheology. Models with quartzite-like rheology display profound transient stages in the velocity, displacement, and stress fields. The predicted transient zone extends about 3-4 times the crustal thickness on each side of the fault, significantly wider than the zone of deformation in elastic models. Models with diabase-like rheology behave similarly to elastic models and exhibit no transient stages. The model predictions are compared with geodetic observations of fault-parallel velocities in northern and central California and local rates of shear strain along the San Andreas fault. The observations are best fit by models which are 10-100 times less viscous than a quartzite-like rheology. Since the lower crust in California is composed of intermediate to mafic rocks, the present result suggests that the in situ viscosity of the crustal rock is orders of magnitude less the rock viscosity determined in the laboratory.

The use of multiple cosmogenic nuclides permits both exposure times and erosion rates to be determined. However, if two nuclides are produced only by spallation reactions, the systematic differences in their accumulation rates depend only on the differences in their production rates and half-lives. The relatively small differences that result require a high degree of analytical precision to yield useful results. In contrast to other spallogenic nuclides, (super 36) Cl is also produced by low-energy neutron absorption, which creates a different pattern of production as a function of depth. We have measured the thermal flux with depth in a concrete block using (super 3) He-filled neutron detectors. The measured thermal neutron profile agrees well with predictions from a simple diffusion- based thermal neutron distribution model. Calculations of (super 36) Cl production using the model suggest that the use of (super 36) Cl along with a purely spallogenic nuclide to determine erosion rates and exposure times should be less sensitive to analytical error than are determinations from two purely spallogenic nuclides.

Profiles determined using differential particle fluxes calculated with the LAHET code system are in good agreement with (super 26) Al, (super 10) Be, and (super 36) Cl experimental data, but the agreement for (super 36) Cl was obtained only after neutron-induced cross sections were modified. Profiles calculated with lunar particle fluxes are much lower than experimental Canyon Diablo profiles. The cosmic ray exposure ages of most samples are near 540 m.y.

AN - 77112906; 11539958 AB - Cyclotron-accelerated heavy ion beams provide a fine degree of control over the physical parameters of radiation. Cytogenetics affords a view into the irradiated cell at the resolution of chromosomes. Combined they form a powerful means to probe the mechanisms of RBE. Cytogenetic studies with high energy heavy ion beams reveal three LET-dependent trends for 1) level of initial damage, 2) distribution of damage among cells, and 3) lesion severity. The number of initial breaks per unit dose increases from a low-LET plateau to a peak at approximately 180 keV/micrometer and declines thereafter. Overdispersion of breaks is significant above approximately 100 keV/micrometer. Lesion severity, indicated by the level of chromosomal fragments that have not restituted even after long repair times, increases with LET. Similar studies with very low energy 238Pu alpha particles (120 keV/micrometer) reveal higher levels of initial breakage per unit dose, fewer residual fragments and a higher level of misrepair when compared to high energy heavy ions at the same LET. These observations would suggest that track structure is an important factor in genetic damage in addition to LET.

Mutagenic effects of high energy charged particles in normal human fibroblasts. AN - 77111910; 11539970 AB - The biological effects of high LET charged particles are a subject of great concern with regard to the prediction of radiation risk in space. In this report, mutagenic effects of high LET charged particles are quantitatively measured using primary cultures of human skin fibroblasts, and the spectrum of induced mutations are analyzed. The LET of the charged particles ranged from 25 KeV/micrometer to 975 KeV/micrometer with particle energy (on the cells) between 94-603 MeV/u. The X-chromosome linked hypoxanthine guanine phosphoribosyl transferase (hprt) locus was used as the target gene. Exposure to these high LET charged particles resulted in exponential survival curves; whereas, mutation induction was fitted by a linear model. The Relative Biological Effect (RBE) for cell-killing ranged from 3.73 to 1.25, while that for mutant induction ranged from 5.74 to 0.48. Maximum RBE values were obtained at the LET of 150 keV/micrometer. The inactivation cross-section (alpha i) and the action cross-section for mutant induction (alpha m) ranged from 2.2 to 92.0 micrometer2 and 0.09 to 5.56 x 10(-3) micrometer2, respectively. The maximum values were obtained by 56Fe with an LET of 200 keV/micrometer. The mutagenicity (alpha m/alpha i) ranged from 2.05 to 7.99 x 10(-5) with the maximum value at 150 keV/micrometer. Furthermore, molecular analysis of mutants induced by charged particles indicates that higher LET beams are more likely to cause larger deletions in the hprt locus.

In 1982, the midpoint of sensitivity of each neutron probe to the detection of hydrogen was determined, as well as the radius of investigation of each probe in crushed Bandelier Tuff with varying water contents. After determining the response of one of the moisture gauges to changes in soil water at the soil-air interface, a neutron transport model was successfully calibrated to predict spatial variations in soil water content. The model was then used to predict various shapes and volumes of crushed Bandelier Tuff interrogated by the neutron moisture gauge. From 1991 through 1994, six neutron moisture gauges were calibrated for soil water determinations in a local topsoil and crushed Bandelier Tuff, as well as for a sample of fine sand and soils from a field experiment at Hill Air Force Base. Statistical analysis of the calibration results is presented and summarized, and a final summary of practical implications for future neutron moisture gauge studies at Los Alamos is included.

More than six major calderas formed between g15 and 7.5 Ma. The central SWNVF caldera cluster consists of the overlapping Silent Canyon caldera complex, the Claim Canyon caldera, and the Timber Mountain caldera complex, active from 14 to 11.5 Ma and centered on topographic Timber Mountain. Locations of calderas older than the Claim Canyon caldera source of the Tiva Canyon Tuff are uncertain except where verified by drilling. Younger peralkaline calderas (Black Mountain and Stonewall Mountain) formed northwest of the central SWNVF caldera cluster. We summarize major revisions of the SWNVF stratigraphy that provide for correlation of lava flows and small-volume tuffs with the widespread outflow sheets of the SWNVF. New laser fusion (super 40) Ar/ (super 39) Ar isotopic ages are used to refine and revise the timing of eruptive activity in the SWNVF. The use of high-sensitivity mass spectrometry allowed analysis of submilligram-sized samples with analytical uncertainties of approximately 0.3% (1), permitting resolution of age differences as small as 0.07 Ma. These results confirm the revised stratigraphic succession and document a pattern of episodic volcanism in the SWNVF. Major caldera episodes (Belted Range, Crater Flat, Paintbrush, Timber Mountain, and Thirsty Canyon Groups) erupted widespread ash-flow sheets within 100-300 k.y. time spans, and pre- and postcaldera lavas erupted within 100-300k.y. of the associated ash flows. Peak volcanism in the SWNVF occurred during eruption of the Paintbrush and Timber Mountain Groups, when over 4500 km (super 3) of metaluminous magma was erupted in two episodes within 1.35 m.y., separated by a 750 k.y. magmatic gap. Peralkaline and metaluminous magmatism in the SWNVF overlapped in time and space. The peralkaline Tub Spring and Grouse Canyon Tuffs erupted early, and the peralkaline Thirsty Canyon Group tuffs and Stonewall Flat Tuff erupted late in the history of the SWNVF, flanking the central, volumetrically dominant peak of metaluminous volcanism. Magma chemistry transitional between peralkaline and metaluminous magmas is indicated by petrographic and chemical data, particularly in the overlapping Grouse Canyon and Area 20 calderas of the Silent Canyon caldera complex. Volcanism in the SWNVF coincided with the Miocene peak of extensional deformation in adjoining parts of the Great Basin. Although regional extension was concurrent with volcanism, it was at a minimum in the central area of the SWNVF, where synvolcanic faulting was dominated by intracaldera deformation. Significant stratal tilting and paleomagnetically determined dextral shear affected the southwestern margin of the SWNVF between the Paintbrush and Timber Mountain caldera episodes. Larger magnitude detachment faulting in the Bullfrog Hills, southwest of the central SWNVF caldera cluster, followed the climactic Timber Mountain caldera episode. Postvolcanic normal faulting was substantial to the north, east, and south of the central SWNVF caldera cluster, but the central area of peak volcanic activity remained relatively unextended in postvolcanic time. Volcanism and extension in the SWNVF area were broadly concurrent, but in detail they were episodic in time and not coincident in space.

The samples were chosen on their lack of weathering and young (historic) ages. The results show that mass transfer from the subducted slab to the mantle sources of the lavas occurred over an extended period, using the half-lives of (super 226) Ra/ (super 230) Th and (super 10) Be. The lavas have high ( (super 230) Th)/( (super 232) Th) ratios correlating with (super 10) Be/ (super 9) Be, (super 87) Sr/ (super 86) Sr and other parameters related to the proportion of subducting sediments involved in their generation. Mechanisms of transport of the radiogenic elements are discussed; whatever the mechanism, however; the addition of subducted material to the mantle occurred over the past 4.5 m.y. up to > 4.5 m.y.), stage II (4.5 m.y.-200 000 yr) and stage III (200 - << 8000 yr). Compared to earlier stages, Stage III probably involved melting with U/Th ratios of the melt becoming fractionated from those of a simple mixture of mantle and subducted material.

Pressure derivatives of the adiabatic bulk modulus (dK (sub S) /dP = 5.3) and shear modulus (dG/dP = 2.0) are derived from the travel times of the compressional (P) and shear (S) waves. These derivatives clearly demonstrate that pressure has a more pronounced effect on the elasticity of the majorite-rich garnet than on the pure pyrope end-member, presumably in response to the coupled substitution of Si and Mg for Al on the octahedral site in the garnet structure. When combined with plausible values for the (as yet unmeasured) temperature derivatives, these new data can be used to calculate velocity-depth profiles along a 1400 degrees C adiabat for the range of depths in which majorite is expected to be stable in the transition zone of the Earth's mantle (450-600 km). For shear waves, these majorite gradients match those from regional seismic models much better than those for a pure olivine mantle. More reliable calculations of elastic wave velocities at mantle temperatures and pressures await measurement of the temperature derivatives of elastic modulus.

The model includes a core-mantle thermal coupling boundary condition which takes into play the secular cooling of the core by the overlying mantle flow. Initial surface Rayleigh numbers between 2X10 (super 7) and 10 (super 8) have been considered. With time the surface Rayleigh number decreases to a value upon which a transition takes place from layered to single-cell convection. This tumultuous period is marked by large-scale coherent breakthrough of cold material, trapped in the transition zone, all the way to the base of the mantle and a violent reaction of hot plume in the upper mantle. Both hot and cold anomalies have large magnitudes. Cold anomalies with temperatures exceeding 1000 K are found at the base of the mantle. The magnitude of the cold anomalies is largest with all three depth-dependent properties. The timescales of this catastrophic event are between 20 and 50 Myr, with the longest being produced by the model with depth-dependent expansivity and viscosity. Results from these simple two-dimensional cartesian models represent a lower bound to the larger cold thermal anomalies, potentially capable of being generated in spherical-shell convection models.

In contrast to previous results with constant thermal expansivity, the decrease of thermal expansivity with depth produces focused plumes, which promote the breakthrough of plumes through the compositional boundary separating the upper and lower mantles. In terms of an averaged buoyancy ratio (compositionally induced density/thermally induced density), plumes can penetrate intermittently the chemical barrier for a buoyancy ratio of around two. Those plumes which can reach the surface are sprayed out and may explain the strong episodicity in the heat-flow and the generation of flood basalts. There is very little entrainment of the upper-mantle material into these mega-plumes. By these singular injection events the upper mantle becomes more and more heterogeneous, whereas the lower mantle remains barely mixed.

The depth to which metastable olivine (alpha ) can survive in a subduction zone and the depth interval over which transformation to beta - or gamma -(Mg,Fe) (sub 2) SiO (sub 4) occurs have been evaluated from experimental kinetic data for the Mg (sub 2) GeO (sub 4) and Ni (sub 2) SiO (sub 4) alpha -gamma transformations and the Mg (sub 2) SiO (sub 4) alpha -beta transformation. The data were extrapolated using a kinetic model for grain-boundary nucleation and interface-controlled growth under non-isothermal and non-isobaric conditions. The results predict that metastable Mg (sub 1.8) Fe (sub 0.2) SiO (sub 4) olivine survives to depths greater than 500 km in the cold interior of rapidly subducting slabs of old lithosphere. The onset of transformation to gamma -(Mg,Fe) (sub 2) SiO (sub 4) (spinel) depends only on growth kinetics and coincides with the 550(+ or -50) degrees C isotherm. Including the effects of latent heat production causes the transformation to occur by a runaway process over a very narrow depth interval. At the onset of transformation, high nucleation rates and low growth rates are consistent with the formation of very fine-grained reaction products which are required for the transformational faulting mechanism of deep-focus earthquakes. When olivine crosses the equilibrium boundaries at higher temperatures (e.g. higher than 700 degrees C at 400 km depth), transformation to beta or gamma occurs much closer to equilibrium, at a depth controlled by nucleation kinetics. In this case, the effect of latent heat production on the transformation kinetics is small and microstructural evolution is unlikely to result in transformational faulting. Below the depth of olivine breakdown, cold slabs are likely to have a complex rheological structure owing to temperature-dependent microstructural evolution during the phase transformation.

No individual seismogram from this array shows a clear P660s phase. Stacks of (up to 113) crosscorrelograms show P660s energy that is weak in comparison with similar stacks elsewhere. Very high amplitude observations of P660s in single seismograms from the same region have been made in a previous study (Paulssen, 1985, Geophys. Res. Lett., 12: 709-712; Paulssen, 1988, J. Geophys. Res., 93: 10489-10500). Such variations may be due to relief on the 660 km discontinuity. In this paper we quantify the effects of different topographies on the time delays, amplitudes, and waveforms of the direct P wave as well as on the P660s converted wave. Synthetic P and P660s waveforms are calculated by applying a Kirchhoff-Helmholtz integration over the wave fields at the 660 km discontinuity interface. For topography on scales of a few hundreds of kilometers, the effects on the P wave are very small compared with those on the P660s phases. Time delays, focused and defocused amplitudes, and waveform distortion of P660s phases influenced by such topography diminish the coherence of P660s in (synthetic) stacks. Our results show that topography of the 660 km discontinuity with dominant scale lengths of a few hundreds of kilometers and variations in depth of + or -15 km to + or -25 km, is consistent with the pattern of P660s observations in single seismograms and stacks.

Therefore, these modes can be used for retrieving the S-wave velocity structure in the mantle and, more specifically, in the transition zone. The procedure used for computing a tomographic model of the mantle is divided into two steps. First, the iterative inverse technique developed by Stutzmann and Montagner (Geophys. J. Int., 113: 669-683, 1993) is used for determining higher-mode phase velocities and a spherically symmetric velocity model associated with each path. A "path" is defined to be the minor or major arc (along a great circle) connecting a small epicentral area, in which several earthquakes are selected, and a station. The use of several earthquakes improves the depth resolution. Simultaneously for each datum, the difference between the spectrum of the observed seismogram and the sum of the synthetic spectra corresponding to the different modes is inverted to retrieve (1) the phase velocity dispersion curves of the fundamental mode and the three first higher modes and (2) the spherically symmetric S-wave velocity model corresponding to this path. In a second step, the higher-mode phase velocity dispersion curves and the S-wave velocity model corresponding to each path are regionalized without a priori constraint to obtain their lateral variations. This method has been applied to long-period GEOSCOPE data. We present preliminary results obtained with about 300 seismograms corresponding to 86 paths for the R1 or R2 trains. The three-dimensional S velocity model has been then expanded in spherical harmonics, to compare it with other models and to determine characteristics of the transition zone.

Several possible causes of this resistance are evaluated. It is concluded that the chemical composition of the lower mantle is similar to that of the upper mantle, and that compositional change is therefore unlikely to be the cause of resistance to slab penetration. The proposal that a large increase of viscosity at the 660 km discontinuity impedes descending slabs is also rejected. However, three other factors are identified, each of which is capable of causing substantial resistance to descending slabs: (1) the negative slope of the transformation of silicate spinel to Mg-perovskite + magnesiowustite; (2) differentiation of oceanic lithosphere into basaltic and depleted peridotitic layers, causing the slab to be buoyant compared with surrounding mantle pyrolite between depths of 660-800 km; (3) the accumulation of former oceanic crust to produce a gravitationally stable layer of garnetite (about 50 km thick) on top of the 660 km discontinuity. The combined effects of these sources of resistance provide a filter for subducted slabs. Those slabs with seismic zones extending below 600 km may possess sufficient negative buoyancy and strength to overcome the barriers and penetrate into the lower mantle. However, the resistance causes strong buckling and plastic thickening of these slabs, which accumulate to form huge blobs or "megaliths" underneath the 660 km discontinuity. In contrast, slabs with seismic zones extending no deeper than 300 km possess much smaller degrees of negative buoyancy and strength and hence are unable to penetrate the 660 km discontinuity. Slabs of this type are recycled within the transition zone and upper mantle. Mixing and petrological homogenization processes are less efficient in the transition zone than in the upper mantle (above 400 km). The transition zone is composed mainly of ancient slabs of differentiated oceanic lithosphere, with discrete lithological domains of former oceanic crust, former harzburgite and former lherzolite. However, in the upper mantle, these lithologies have been homogenized via convective mixing and partial melting to form a uniform pyrolite composition. Seismic velocity gradients in the heterogeneous mixture of lithologies of the transition zone are higher than they would be in homogeneous pyrolite, because of the survival of clinopyroxene to a depth of about 500 km. This may contribute towards high seismic velocity gradients observed in the transition zone. The behaviour during partial melting of heterogeneous lithologies from the transition zone is also quite different from the partial melting of homogeneous pyrolite. The transition zone provides the principal source region for alkaline intraplate basalts world-wide (including ocean island basalts) whereas the homogeneous pyrolite source region of the upper mantle yields mid-ocean ridge basalt magmas.

At pressures of 17-18 GPa, diopside undergoes a decomposition reaction to an assemblage of CaSiO (sub 3) -perovskite+(Ca,Mg)SiO (sub 3) -garnet or -ilmenite, depending on temperature. The Clapeyron slope for the breakdown reaction: CaMgSi (sub 2) O (sub 6) = CaSiO (sub 3) +(Ca, Mg)SiO (sub 3) is -2 MPa K (super -1) . When coupled with a re-examination of clinopyroxene stability in other more complex peridotite systems, the experimental data are consistent with a recent proposal that the 520 km discontinuity in the transition region is caused by the exsolution of CaSiO (sub 3) -rich perovskite from garnet, rich in majorite component.

Depth-dependent properties of thermal expansivity, viscosity and thermal conductivity have been incorporated. Three-dimensional solutions for surface Rayleigh number (Ra (sub s) ) between 2X10 (super 6) and 4X10 (super 8) show that there is a distinct transition between Ra (sub s) = 4X10 (super 7) and 10 (super 8) in which the system changes from single-layered to layered convection with the mass flux decreasing to below 10% at Ra (sub s) = 10 (super 8) . Surface heat flux does not decrease with increasing Ra (sub s) and with the accompanying decrease in the mass flux at the transition zone. The effects of internal heating are to reduce the wavelengths of the planforms which cause greater degree of layering in the system. Comparison between 2D and 3D results shows that there is a greater mass flux passing through the transition zone in the 2D models for the 5X5X1 box, but for larger aspect ratio (8X8X1) the 3D flows become more layered than the corresponding 2D solution. Increasing the magnitude of the negative Clapeyron slope by three times the experimental value can bring about a dramatic reduction in the amount of mass flux across the 670 km discontinuity. Results from a 8X8X1 box show that a greater amount of layering is produced in the larger aspect-ratio configuration because of the shorter wavelengths of the developed planforms. Increasing the degrees of freedom in a 3D system by either greater amounts of convective vigor or larger domains may give rise to a greater tendency for layered convection. Three-dimensional spherical shell models may produce a greater degree of layering than the corresponding axisymmetric models.

AN - 50188196; 1995-009548 AB - Large-scale seismic models of the three-dimensional (3D) variations in elastic properties will be biased by topography on mantle boundaries to the extent that volumetric and topographic structures produce similar effects in the data. To date, seismic inversions for global-scale 3D elastic models of the mantle have largely ignored the effect that topography on the major mantle discontinuities would have on estimating these models. In this paper we address three questions: (1) to what extent does unmodeled structure on the 410 and 660 km boundaries bias volumetric structure in inversions based on normal mode-mantle wave structure coefficients, absolute S-wave travel times, and differential SS-S travel times? (2) Can the differences in the sensitivity of S waves, SS-S phase pairs, and normal mode-mantle wave data be exploited to estimate transition zone volumetric models that are relatively unbiased by topographic structure? (3) Have current volumetric models resolved the trade-off that exists between volumetric and topographic structures? To address question (1), synthetic experiments were performed which show that volumetric models inferred from normal mode-mantle wave data can be biased by an average value of 20-25% in r.m.s. amplitude in the transition zone relative to current aspherical Earth models, depending on the model parametrization employed. The average transition zone volumetric bias of models inverted from absolute travel times from both transition zone and lower-mantle bottoming S rays that are imprinted with the same topographic signatures is reduced by at least by a factor of five relative to models inverted from normal mode-mantle wave data alone. A reduction in bias by a factor of about four is obtained using SS-S phase pairs in which the SS legs bottom in both the transition zone and lower mantle. The use of lower-mantle bottoming S rays or SS-S phase pairs with the SS legs bottoming in the lower mantle reduces the bias only by an average factor of about two to three relative to the normal mode-mantle wave inversion. These estimates of bias reduction can vary with the type of damping or smoothness constraints that are applied in the inversion. With respect to question (2), these results suggest that, in principle, absolute S-wave travel time data can be used to desensitize volumetric inversions to the bias caused by topography on the transition zone boundaries. In practice, however, near-source structure that contaminates S-wave travel times would diminish this capability. The use of SS-S differential times for SS waves which bottom in the transition zone and mantle waves sensitive to transition zone structure but insensitive to the 660 km boundary, should be the most effective means of overcoming the trade-off. To address question (3), we adopt the criterion that the combination of an unbiased volumetric model with an accurate topographic model should provide a better fit to normal mode structure coefficients than the volumetric model alone. The boundary model Topo660a when added to the volumetric model S12 (sub -) WM13 fits the normal mode structure coefficients significantly better than the volumetric model alone. However, more recent models of 410 and 660 km boundary topography degrade the fit of the volumetric models S12 (sub -) WM13 and SH.10c.17 to the normal mode structure coefficients, suggesting that there is not yet a conclusive answer to this question.

The midpoints of the propagation paths lie along the northern margin of the Australian continent. Most of the observations come from a Guralp CMG3 seismometer at the Warramunga Array, but these have been supplemented by field deployments using comparable instrumentation. Two groups of sources, (1) along the Flores Arc, Indonesia, with propagation under northwestern Australia, and (2) in New Guinea, with paths to the NNE of the array, have been used to construct composite record sections for P, SV and SH waves over the distance range 1250-3600 km. The choice of the two source zones was based on earlier short-period studies, and the broad-band observations confirm the presence of noticeable differences in P velocity profiles for paths whose turning points are separated by about 1000 km. The S waves recorded on the radial (SV) and tangential (SH) components are of comparable quality because the hard-rock recording sites minimise the influence of coupling to P on the radial component. As the P and S sections are prepared from the same events, we are able to make direct estimates of P/S velocity ratios for the mantle transition zone. This ratio increases from 1.77 at the top of the mantle to 1.85 at the 410 km transition, indicating that the S-wave velocity gradients are rather lower than might be expected. However, through the transition zone down to 660 km the S-wave gradients increase and the P/S velocity ratio is less than 1.81 below the 660 km transition. There is a significant difference in the frequency content of P and S waves beyond 2000 km.

The reaction products and microstructures have been studied in detail by transmission electron microscopy. Under these disequilibrium conditions, San Carlos olivine transforms to beta -phase and spinel, with Mg/Fe ratios which are not consistent with equilibrium compositions. The transformation to both phases occurs by a nucleation and growth mechanism, involving nucleation at olivine grain boundaries. Both phases contain characteristic stacking faults on (010) (beta -phase) and {110} (spinel), and some spinel grains show extreme degrees of disorder. Although there is uncertainty in the exact stability field of the experiment, the results are consistent with formation of metastable spinel, probably within either the alpha +beta or beta stability fields. Metastable spinel progressively transforms back to beta -phase by a shear-like mechanism involving a highly disordered spinelloid phase, which may be a transitional phase in the transformation. Based on these results and available kinetic data metastable formation of spinel in a subducting oceanic slab, within the alpha +beta or beta stability fields, is possible at temperatures below 1000 degrees C.

Advances in the application of the multi-anvil apparatus to deformation studies allowed us to deform beta -Mg (sub 1.8) Fe (sub 0.2) SiO (sub 4) at pressures of 14 GPa and greater and 1450 degrees C. San Carlos olivine was transformed to beta -phase and allowed to relax at an average strain rate of 1X10 (super -5) for 3 h and subsequently deformed at a constant strain rate of 1X10 (super -4) . The olivine to beta -phase transformation and deformation result in a bimodal grain size with the large grains having a preferred orientation. Deformation by dislocation creep and subgrain formation causes grain size reduction and nearly identical microstructures in the relaxed and high strain-rate samples. The dominant slip systems involved in the deformation of polycrystalline beta -phase appear to be (010)[100] and (010)[001]. Slip in the [001] direction occurs by the glide of disassociated dislocations and produces Shockley-type stacking faults. The anisotropy that develops from the olivine to beta -phase transformation under stress and subsequent dislocation creep may have profound effects on dynamic processes in the transition zone.

The tomographic image indicates that the southern Great Basin has a flat Moho at about 30 km depth. We attribute the flat Moho to both underplating by partial melt from the uppermost mantle and to ductile flow in the crust. Magmatic underplating probably dominates where Pn velocities are low (7.9 km/s). Low velocity regions occur predominantly beneath the east margin of the Walker Lane Belt and the Las Vegas Shear Zone suggesting that these shear zones overlie a zone of relatively weak mantle. A region of high Pn velocity northeast of Nevada Test Site (NTS) may correspond to old lithosphere or to a region that has experienced extensive basalt extraction.

Such an origin could have important consequences if Yucca Mountain is developed as an unsaturated site for disposal of high-level nuclear waste. At odds with this hypothesis are the absence of features that should be present at fault-fed springs (e.g., fissure-ridge mounds with microterraces) and the preservation within root casts of delicate pedogenic microfossils such as calcified filaments and needle-fiber calcites. Chemical evidence of pedogenic origin is found in Fe and Sc enrichments that require prior weathering of detritus in the calcretes, as opposed to direct incorporation of adjacent unweathered bedrock. Carbonate and silica abundances and accumulation rates are well within the scope of pedogenic processes. Sources of carbonate are eolian, whereas silica is derived in part by dissolution of local volcanic glasses but also by extensive dissolution of unstable silica minerals (tridymite and cristobalite) that are abundant in the local tuffs. The siliceous calcretes at Yucca Mountain are pedogenic and provide no evidence in support of conjectured spring activity.

The results show that structurally distinct U(VI) sorption complexes form on montmorillonite as a function of coverage; energetically different sites are involved in the sorption process. The differences between the dominant species at up to 7% c.e.c. and those at higher coverages may reflect sorption onto amphoteric edges vs fixed-charge sites, respectively. Sorption complexes exist that are structurally distinct from solution species, and uranyl sorption complexes that form at low coverages are the most distinct from those in aqueous solution.

In this study, we measure the sulfur and chlorine contents of melt inclusions and matrix glasses in the eruption products to determine petrologic estimates of SO (sub 2) and Cl emissions. We compare the results with emission estimates based on COSPEC and TOMS data for SO (sub 2) and data for Cl/SO (sub 2) in plume samples. For the explosive vent clearing period (December 14-22, 1989), the petrologic estimate for SO (sub 2) emission is 21,000 tons, or approximately 12% of a TOMS estimate of 175,000 tons. For the dome growth period (December 22, 1989 to mid-June 1990), the petrologic estimate for SO (sub 2) emission is 18,000 tons, or approximately 3% of COSPEC-based estimates of 572,000-680,000 tons. The petrologic estimates give a total SO (sub 2) emission of only 39,000 tons compared to an integrated TOMS/COSPEC emission estimate of approximately 1,000,000 tons for the whole eruption, including quiescent degassing after mid-June 1990. Petrologic estimates also appear to underestimate Cl emissions, but apparent HCl scavenging in the plume complicates Cl emission comparisons. Several potential sources of "excess sulfur" often invoked to explain petrologic SO (sub 2) deficits are concluded to be unlikely for the 1989-1990 Redoubt eruption-- e.g., breakdown of sulfides, breakdown of anhydrite, release of SO (sub 2) from a hydrothermal system, degassing of commingled infusions of basalt in the magma chamber, and syn-eruptive degassing of sulfur from melt present in non-erupted magma. Leakage and/or diffusion of sulfur from melt inclusions do not provide convincing explanations for the petrologic SO (sub 2) deficits either. The main cause of low petrologic estimates for SO (sub 2) is that melt inclusions do not represent the total sulfur content of the Redoubt magmas, which were vapor-saturated magmas carrying most of their sulfur in an accumulated vapor phase. Almost all the sulfur of the SO (sub 2) emissions was present prior to emission as accumulated magmatic vapor at 6-10 km depth in the magma that supplied the eruption; whole-rock normalized concentrations of gaseous excess S in these magmas remained at approximately 0.2 wt.% throughout the eruption, equivalent to approximately 0.7 vol.% at depth. Data for CO (sub 2) emissions during the eruption indicate that CO (sub 2) at whole-rock concentrations of approximately 0.6 wt.% in the erupted magma was a key factor in creating the vapor saturation and accumulation condition making a vapor phase source of excess sulfur possible at depth. When explosive volcanism involves magma with accumulated vapor, melt inclusions do not provide a sufficient basis for predicting SO (sub 2) emissions. Thus, petrologic estimates made for SO (sub 2) emissions during explosive eruptions of the past may be too low and may significantly underestimate impacts on climate and the chemistry of the atmosphere.

Dalhart is the name of an underground nuclear test that was executed at the Nevada Test Site at a depth of 2100 ft on October 13, 1988. The test occurred below the static water level of 1667 ft and created multiple radioactive isotopes or fission products. These radioactive isotopes penetrated the surrounding formations and chimney region above the test and were retained there. A 19 degrees 9-7/8-inch diameter slant hole was drilled to sample the geologic material in the chimney region above the Dalhart test for the purpose of assessing the distribution of radioactivity in and around the shot site. A 30-ft core recovered from a vertical depth of 1628 ft in the collapsed zone or chimney region and above the original static water level was found to be free of radionuclides. Drilling was completed to a vertical depth of 2156 ft with the present static water level at a vertical depth of 1644 ft. Gamma-ray spectroscopy log measurements, made within the drill pipe while drilling fluid was pumped through this pipe, indicate that radioactive material produced by the test was present from the vertical depth interval of 1746-2156 ft. Side-wall samples acquired from the vertical depth interval of 1721-2089 ft and analyzed in the field contained radionuclides such as (super 137) Cs, (super 125) Sb, (super 106) Ru, plus the natural radioactive background of potassium, uranium, and thorium. These samples were sent to Los Alamos to determine the complete radionuclide content at each depth. These analyses were used with the gamma-ray spectroscopy logging data to determine the subsurface vertical radionuclide distribution at the Dalhart site.

The age of flows ranges from approximately 2 to 100 ka and multiple TL analyses by the total bleach method yielded ages that overlap at one sigma with independent chronologic control. The TL signal of one sample of baked sediment beneath a lava flow with an inferred age of at least 641 + or - 54 ka was near saturation, perhaps reflecting a relatively high environmental dose rate, and is not datable by TL. This study underscores several major limitations of luminescence geochronology, the natural spatial and temporal variability in environmental radioactivity and the susceptibility of silicate minerals to the growth and retention of a luminescence signal.

The dynamics are dominated by accumulation of cold linear downwellings into rounded pools above the endothermic phase change at 670 km depth, resulting in frequent "avalanches" of upper mantle material into the lower mantle. The effect of the exothermic phase transition at 400 km depth is to reduce the overall degree of layering by pushing material through the 670-km phase change, resulting in smaller and more frequent avalanches, and a wider range of morphologies. Large quantities of avalanched cold material accumulate above the coremantle boundary (CMB), resulting in a region of strongly depressed mean temperature at the base of the mantle. The 670-km phase change has a strong effect on the temperature field, with three-distinct regions being visible: (1) the upper mantle, containing linear downwellings and pools of cold material in the transition zone and characterized by a high amplitude long wavelength spectrum; (2) the midmantle, containing quasi-cylindrical avalanche conduits and characterized by a low amplitude, broad spectrum; and (3) the deep mantle, containing large pools of cold, avalanched material and characterized by a high amplitude, ultra-red (i.e., long wavelength) spectrum. The effect on the velocity field is very different. Flow penetration across the 670-km phase change is strongly wavelength-dependent, with easy penetration at long wavelengths but strong inhibition at short wavelengths. Thus, when comparing numerical models with long wavelength seismic tomography, diagnostics based on the density field, such as the radial correlation function, are much more sensitive to the effects of phase transitions than those based on the velocity field. The amplitude of the geoid is not significantly affected by the partial layering, because the contribution from the strong heterogeneity in the transition zone is almost perfectly balanced by the contribution from deflection of the 670-km discontinuity. Avalanches are associated with geoid lows. However, a more complex viscosity structure is required to correctly match the sign of the geoid over slabs in Earth.

The Laboratory routinely monitors for radiation and for radioactive and nonradioactive materials at (or on) Laboratory sites as well as in the surrounding region. LANL uses the monitoring results to determine compliance with appropriate standards and to identify potentially undesirable trends. Data were collected in 1992 to assess external penetrating radiation; quantities of airborne emissions and liquid effluents; concentrations of chemicals and radionuclides in ambient air, surface waters and groundwaters, municipal water supply, soils and sediments, and foodstuffs; and environmental compliance. Using comparisons with standards, regulations, and background levels, this report concludes that environmental effects from Laboratory operations are small and do not pose a demonstrable threat to the public, laboratory employees, or the environment.

X-ray absorption, optical luminescence, and Raman vibrational spectroscopies were used to determine uranium speciation in contaminated soils from the US DOE's former uranium production facility at Fernald, Ohio. These analyses were carried out both before and after application of one of the various decontamination technologies being developed within the Integrated Demonstration. This year the program focused on characterization of the uranium speciation remaining in the soils after decontamination treatment. X-ray absorption and optical luminescence spectroscopic data were collected for approximately 40 Fernald soil samples, which were treated by one or more of the decontamination technologies.

Over the past few years, there has been an increased interest in horizontal wells for environmental remediation. Despite the interest and potential benefits of horizontal wells, there has been little study of the relative performance of horizontal and vertical vapor extraction wells. This study uses numerical simulations to investigate the relative performance of horizontal versus vertical vapor extraction wells under a variety of conditions. The most significant conclusion that can be drawn from this study is that in a homogeneous medium, a single, horizontal vapor extraction well outperforms a single, vertical vapor extraction well (with surface capping) only for long, linear plumes. Guidelines are presented regarding the use of horizontal wells.

These efforts assume that data obtained in such studies will be interpretable in terms of changes in complexation of the metal center. However, the current understanding of 5f electronic structure is based on data from solid state doped single crystals. In those studies, the local coordination geometry about the central actinide ion is maintained in an almost perfect high-symmetry environment and will have little relevance for species in solution where deviations from perfect high symmetry tend to be the rule rather than the exception. The authors have developed a vigorous research program in the systematic preparation and spectroscopic characterization of synthetic actinide complexes (Th, U, Np, and Pu) in which they can control nuclearity, oxidation state, and molecular structure. These complexes have been used to determine how observable electronic transitions are perturbed in response to structural changes in the complex in solution. From the spectra obtained for these model complexes, the authors have found that the f-f transitions naturally fall into obvious groupings by coordination number and symmetry by which they can now differentiate between monomeric, dimeric, and trimeric species in solution. The study of radionuclide speciation is fundamentally important to the determination of radionuclide solubility in the groundwater at Yucca Mountain.

The goal of the technology demonstration was to stimulate naturally occurring methanotrophic bacteria at the SRID site with injection of methane, air and air-phase nutrients (nitrogen and phosphate) such that significant amounts of the chlorinated solvent present in the subsurface would be degraded. Our approach is based on site-specific numerical simulations using the TRAMP computer code. In this report, we discuss the interactions among the physical and biochemical processes involved in in situ bioremediation. We also investigate improvements to technology performance, make predictions regarding the performance of this technology over long periods of time and at different sites, and compare in situ bioremediation with other remediation technologies.

(Part 1 in this issue) for assessing contamination due to subsurface releases of non-aqueous-phase liquids (NAPL's). Attention is focussed on situations involving one-, two- and three-dimensional flow through porous media. The model formulations and numerical schemes are tested for highly nonlinear field conditions. The utility and accuracy of various simplifications to certain simulation scenarios are assessed. Five simulation examples are included for demonstrative purposes. The first example verifies the model for vertical flow and compares the performance of the fully three-phase and the passive-air-phase formulations. Air-phase boundary conditions are noted to have considerable effects on simulation results. The second example verifies the model for cross-sectional analyses involving LNAPL and DNAPL migration. Finite-difference (5-point) and finite-element (9-point) spatial approximations are compared for different grid aspect ratios. Unless corrected, negative-transmissivity conditions were found to have undesirable impact on the finite-element solutions. The third example provides a model validation against laboratory experimental data on 5-spot water-flood treatment of oil reservoirs. The sensitivity to grid orientation is noted for the finite-difference schemes. The fourth example demonstrates model utility in characterizing the 3-D migration of LNAPL and DNAPL from surface sources. The final example presents a modeling study of air sparging. Critical parameters affecting the performance of air-sparging system are examined. In general, the modeling results indicate sparging is more effective in water-retentive soils, and larger values of sparge influence radius may be achieved for certain anisotropic conditions.

In some cases wave excitation may appreciably increase the mobility of fluids. The effect of elastic waves on the permeability of saturated rock has been confirmed in numerous laboratory experiments. Two related applications have arisen from these findings. In the first application, high-power ultrasonic waves are applied for downhole cleaning of the near-wellbore in producing formations that exhibit declining production as a result of the deposition of scales and precipitants, mud penetration, etc. In many cases, ultrasound effectively removes the barriers to oil flow into the well. The ultrasonic method is reported to be successful in 40-50 percent of the cases studied. In the case of successful treatment, the effect of improved permeability may last up to several months. Whereas this method has a very local effect, a second application is used to stimulate the reservoir as a whole. Here seismic frequency waves are applied at the earth's surface by arrays of vibroseis-type sources. This method has produced promising results; however, further testing and understanding of the mechanisms are necessary.

AN - 76567608; 8023331 AB - Human inhalation exposures to relatively high mass concentrations of the oxidant gas nitrogen dioxide (NO2) can result in a variety of pulmonary disorders, including life-threatening pulmonary edema, pneumonia, and bronchiolitis obliterans. Inasmuch as most experimental studies to date have examined NO2-induced lung injury following exposures to near ambient or supra-ambient concentrations of NO2, e.g., < or = 50 ppm, little detailed information about the pulmonary injurious responses following the acute inhalation of higher NO2 concentrations that are more commensurate with some actual human exposure conditions is currently available. Described in this report are the results from a series of investigations in which various aspects of the inhalation toxicity of high concentrations of NO2 have been examined in laboratory rats. In the first component of our study, we characterized the kinetic course of development of lung injury following acute exposures to high concentrations of NO2 delivered over varying durations, and we assessed the relative importance of NO2 exposure concentration versus exposure time in producing lung injury. For a given exposure duration, the resulting severity of lung injury was found to generally scale proportionately with inhaled mass concentration, whereas for a given concentration of inhaled NO2, the magnitude of resulting injury was not directly proportional to exposure duration. Moreover, evidence was obtained that indicated exposure concentration is more important than exposure time when high concentrations of NO2 are inhaled. In a second component of our investigation, we assessed the pulmonary injurious response that occurs when NO2 is inhaled during very brief, 'high burst' exposures to very high concentrations of NO2. Such exposures resulted in significant lung injury, with the magnitude of such injury being directly proportional to exposure concentration. Comparisons of results obtained from this and the first component studies additionally revealed that brief exposures to the very high concentrations of NO2 are more hazardous than longer duration exposures to lower concentrations. In a third study series, we examined pre-exposure, exposure, and post-exposure modifiers of NO2-induced lung injury, including dietary taurine, minute ventilation, and post-exposure exercise. Results from these studies indicated: (i) dietary taurine does not protect the rat lung against high concentration NO2 exposure, (ii) the severity of acute lung injury in response to NO2 inhalation is increased by an increase in minute ventilation during exposure, and (iii) the performance of exercise after NO2 exposure can significantly enhance the injurious response to NO2.(ABSTRACT TRUNCATED AT 400 WORDS) JF - Toxicology AU - Lehnert, B E AU - Archuleta, D C AU - Ellis, T AU - Session, W S AU - Lehnert, N M AU - Gurley, L R AU - Stavert, D M AD - Pulmonary Biology-Toxicology Program, Los Alamos National Laboratory, New Mexico 87545.

The soil used was obtained from the site of the Feed Materials Production Center (FMPC) near the village of Fernald in Ohio. The testing is being conducted on a laboratory scale, but it is intended that this methodology will eventually be enlarged to field scale where, millions of cubic meters of uranium-contaminated soil can be remediated. The laboratory scale experiments show that, using carbonate/bicarbonate solutions, uranium can be effectively removed from the soil from initial values of around 600 ppM down to 100 ppM or less. The goal of this research is to selectively remove uranium from the contaminated soil, without causing serious changes in the characteristics of the soil. It is also hoped that the new technologies developed for soil remediation at FEMP will be transferred to other sites that also have uranium-contaminated soil.

Over a 10-week monitoring period, 110 microearthquake events were recorded using a 3-component borehole geophone deployed in a well 400 ft north of the producing well. Events were detected up to 4000 ft from the monitor well. The majority of events were detected within 2000 ft. During the monitoring period the well produced at a sustained rate of approximately 100 barrels per day. The microearthquake signals have the characteristics of shear-failure strain release. The event rate increased over the 10-week monitoring period. Events locations align in NE-SW trends with one trend intersecting the production well. The event alignments and the character of the signals suggest shear-failure is induced from reservoir pressure reduction. This may imply that shear failure occurs along fractures being drained and that microseismic monitoring during primary production could be used to map fractures controlling oil production. Significant potential for high yield oil production has been demonstrated by recent discoveries in Clinton County. Production is from tight, fractured carbonates at depths ranging from about 750 to 2400 ft. The fractured reservoir of recent interest in Clinton County occurs in a predominantly limestone unit known as the High Bridge Group located above the Knox Group. The High Bridge Group was deposited in a shallow marine to tidal-flat environment, and consist mainly of argillaceous limestone of low porosity and permeability. Typical oil production from the unfractured matrix is on the order of 3 barrels per day. Local fracture production is suggested by high initial oil-production rates in excess of 400 barrels per hour and sustained rates commonly greater than 100 barrels per day. Despite the many wells drilled recently and in the past, the nature of the subsurface fracture system controlling high-yield production is not well known. As a result, the success ratio of wildcats and even step-out wells is extremely low. In conjunction with currently available information and technologies, microseismic fracture mapping could greatly improve the successful exploration and development of the area's oil resources by providing additional knowledge of the relationship of fractures controlling production with the local and regional geology.

A steady-state, model of the JPG area was developed to examine the effects of DU in soils, water, and vegetation on deer that were hunted and consumed by humans. The RESRAD code was also used to estimate the effects of farming the impact area and consuming the products derived from the farm. The steady-state model showed that minimal doses to humans are expected from consumption of deer that inhabit the impact area. Median values for doses to humans range from about 1 mrem (+ or -2.4) to 0.04 mrem (+ or - 0.13) and translate to less than 1X10 (super -6) detriments (excess cancers) in the population. Monte Carlo simulation of the steady-state model was used to derive the probability distributions from which the median values were drawn. Sensitivity analyses of the steady-state model showed that the amount of DU in airborne dust and, therefore, the amount of DU on the vegetation surface, controlled the amount of DU ingested by deer and by humans. Human doses from the RESRAD estimates ranged from less than 1 mrem/y to about 6.5 mrem/y in a hunting scenario and subsistence farming scenario, respectively. The human doses exceeded the 100 mrem/y dose limit when drinking water for the farming scenario was obtained from the on-site aquifer that was presumably contaminated with DU. The two farming scenarios were unrealistic land uses because the additional risk to humans due to unexploded ordnance in the impact area was not figured into the risk estimate. The doses estimated with RESRAD translated to less than 1X10 (super -6) detriments to about 1X10 (super -3) detriments. The higher risks were associated only with the farming scenario in which drinking water was obtained on-site.

Solubility and speciation data are useful in verifying the validity of geochemical codes that are a part of predictive transport models. Results are presented from solubility and speciation experiments of (super 237) NpO (sub 2) (super +) , (super 239) Pu (super 4+) , and (super 241) Am (super 3+) /Nd (super 3+) in a modified UE-25p No. 1 groundwater (from the Yucca Mountain region, Nevada, which is being investigated as a potential high-level nuclear waste disposal site) at two different temperatures (25 degrees and 60 degrees C) and three pH values (6.0, 7.0, 8.5). The solubility-controlling steady-state solids were identified and the speciation and/or oxidation states present in the supernatant solutions were determined. The neptunium solubility decreased with increasing temperature and pH. Plutonium concentrations significantly decreased with increasing temperature at pH 6 and 7. The concentration at pH 8.5 hardly decreased at all with increasing temperature. At both temperatures the concentrations were highest at pH 8.5, lowest at pH 7, and in between at pH 6. For the americium/neodymium solutions, the solubility decreased significantly with increasing temperature and increased somewhat with increasing pH.

The convecting thermal waters: 1) aided oil transport, 2) accelerated source-rock maturation by increasing the local, shallow thermal budget, 3) increased reservoir porosity by dolomite dissolution and 4) precipitated quartz and kaolinite to form a diagenetic seal. Vuggy, brecciated, Devonian, Mississippian and Pennsylvanian dolomite reservoir rocks display late-stage, fracture-filling quartz with oil and aqueous fluid inclusions. T (sub h) and apparent salinities of fluid inclusions, and oxygen and hydrogen isotopes in quartz (delta (super 18) O and delta D, SMOW), match present-day waters. Grant Canyon T (sub h) range 90-165 degrees C, show a strong peak at 105-115 degrees C and, after P correction by approx +8 degrees C, match oil field waters of 116-122 degrees C. Oil field delta (super 18) O = -14 to -15 per mille and delta D = 109 to 119 per mille . These isotopic values are lighter than cold meteoric waters from nearby mountains; suggesting oil-field waters were recharged under cooler-than-present climatic conditions, presumably glacial, i.e. the oil field waters are several m.y. old.

Paleomagnetic data from individual ash flow sheets document no significant relative vertical-axis rotation among localities within central SWNVF, an area of relatively low stratal tilts and widely spaced faults. A time-averaged mean paleomagnetic direction (D = 351.4 degrees , I = 52.7 degrees , alpha (sub 95) = 4.5 degrees ) calculated from data from numerous separate rock units suggests that the central SWNVF underwent minimal counterclockwise vertical-axis rotation (R = -7.1 degrees + or - 6.6 degrees ) with respect to the North American craton. No clockwise vertical-axis rotation is found to support projection of dextral faults of the Walker Lane beneath the central SWNVF. Clockwise rotation of variable magnitude is common at numerous sites from southern and western margins of the field. These clockwise rotations probably reflect dextral shear strain developed at the interface between the little extended central SWNVF block and more strongly extended areas to the south and southwest of the field. Negligible rotation of 11.45-Ma to 13.25-Ma tuffs relative to the central SWNVF was found at the southeast margin of the field where 90 degrees clockwise rotation at the northwest termination of the Las Vegas Valley shear zone had been postulated. Any clockwise rotation in this area must predate 13.25 Ma, and thus dextral shear within this part of the Walker Lane belt was not synchronous or connected across the southern margin of the field. Small counterclockwise vertical-axis rotation relative to the craton, as found for the central SWNVF block, might be a regional feature in the western Great Basin.

The low-velocity body is a large asymmetrical volume which deepens to the east, extending from depths of 7 to 30 km. It contains lower velocities than originally proposed by earlier teleseismic studies. In particular, there is a tabular feature between 7 and 11 km depth that has a reduction in velocity of about 30%. These low velocities imply a much greater percentage of melt in the crust beneath Long Valley caldera than previously estimated. Array analysis of large delayed arrivals identifies them to be Ps converted waves from the shoulders and roof of this tabular zone. These conversions bound the depth to the magma chamber roof to be within about 10 km of the surface. Our results are consistent with elements from several other studies, and we present an integrated and improved model of crustal structure at Long Valley. The concordance of the deeper low-velocity zones with regional structural trends implies that the shallow low velocity feature is a cupola on top of an asymmetric diapiric ridge rising up from the migmatized lower crust of the Basin and Range. We present two contrasting interpretations of the geometry of low-velocity zones in the crust: one implies a time invariant magma chamber and conduit system for Long Valley caldera, the other implies an evolution of that system from a simple vertical regime to its current asymmetrical geometry.

We have combined this review with a compilation of old and newly acquired gravity and seismic travel time data, producing a unified interpretation along a northwest to southeast profile. The analysis supports a new interpretation of the Silent Canyon caldera complex. The caldera is found to be more asymmetric than previously suggested, with the southeastern boundary formed by linear, high-angle normal faults and a more gently sloping northwestern boundary. The total thickness of volcanic units within the caldera complex does not appear to exceed 5 km. The shallow structure at Pahute Mesa could have a profound effect on the seismic response for regional and teleseismic signals from this nuclear test site. The Silent Canyon caldera complex is actually a set of nested calderas first filled by thick (>1 km) postcaldera lavas and subsequently buried by outflow sheets of the Timber Mountain caldera to the south. Thick, postcaldera lavas filled a half-graben structure formed west of the West Greeley fault, dropping the tops of the youngest caldera-forming units to depths in excess of 2 km. Therefore the western boundary of the caldera complex is poorly defined. East of the West Greeley fault, two overlapping calderas are defined, and stratigraphic data suggest the presence of even older calderas. The youngest caldera, the calc-alkaline Area 20 caldera, is well defined from drill hole data. The Area 20 caldera overlaps the 13.6 Ma peralkaline Grouse Canyon caldera, which is less well defined, but apparently collapsed in trap-door style along the Almendro fault. For both these calderas, collapse continued after the main caldera-forming eruption, concurrent with the accumulation of thick (>1 km) lavas within the peripheral collapse zones. The geophysical interpretation indicates that the major structural boundary of the caldera complex corresponds to the NNE trending Scrugham Peak and Almendro faults, which offset the pre-Tertiary contact more than 1 km but have less than 200 m offset in rocks of 11 Ma age. Drill hole data show that offsets along these faults increase systematically within older (up to 15 Ma) units, which are commonly rotated eastward in a style similar to units at the surface. Abrupt changes in the subsurface thickness of the caldera-forming units occur across the faults, indicating that these linear features served as caldera boundaries.

AN - 76382814; 8119966 AB - Three isoenzyme forms (designated A, B, and C) of O-acetylserine sulfhydrylase were purified from Datura innoxia suspension cultures. Isoenzyme A is the most abundant form, comprising 45-60% of the total activity. Isoenzymes C and B comprise 35-40% and 10-20% of the activity, respectively. The specific activities of the purified isoenzymes are similar (870-893 mumol of cysteine/min/mg of protein). Molecular masses for isoenzymes A, B, and C, estimated by analytical size exclusion high performance liquid chromatography, are 63, 86, and 63 kDa, respectively. Isoenzymes A and B are homodimers; isoenzyme C is a heterodimer. Spectral analysis indicates that these isoenzymes possess a pyridoxal 5'-phosphate cofactor that binds the O-acetylserine substrate. Binding is reversible by addition of the sulfide substrate. The O-acetylserine sulfhydrylase isoenzymes are active over a broad temperature range, with maximum activity between 42 and 58 degrees C. They are active only between pH 7 and 8, with optimal activity at pH 7.6. Kinetic analysis indicates these enzymes are allosterically regulated and exhibit positive cooperativity with respect to both substrates. They are inhibited by sulfide concentrations above 200 microM. The kinetic analysis together with the physical and spectrophotometric characteristics indicate that the O-acetylserine sulfhydrylase enzymes have two active sites.

AN - 76362976; 8107140 AB - The gene V protein of bacteriophage f1 binds to single-stranded nucleic acids and is essential for propagation of phage f1. We tested the function of gene V protein mutants with single amino acid substitutions in two ways: by the ability of the mutant proteins to support phage growth, and by the ability of the mutant proteins, when expressed at high levels, to inhibit the growth of Escherichia coli. The results of the tests were used to identify sites in the protein that are relatively tolerant or intolerant to substitution, where tolerant sites are defined as those where most substitutions do not affect the function of the protein. The two assays generally yielded similar results for the tolerance of sites to substitution. Many sites that are less than 10% exposed to the solvent are relatively intolerant of substitution, with even very conservative substitutions leading to loss of function in some cases such as Ile to Leu at residue 6. Some buried sites such as Ile47 are more tolerant, with even a substitution of Ile to Thr leading to a functional protein based on the ability of the proteins to inhibit the growth of E. coli. Some surface sites in the protein (> 10% exposure to solvent) that are thought to be near the location of bound oligonucleotides, such as Arg16, Val19, Ser20, Arg21, Tyr26, Lys46 and Arg80, are sensitive to substitution. Other side-chains thought to be close to bound oligonucleotides, including Leu28, can be replaced with a number of amino acids with little loss of function based on either assay. Most non-Gly/Pro surface residues thought to be distant from the locations of bound oligonucleotides are relatively tolerant of substitution, except for two small residues (Ala11 and Thr14), two aromatic residues (Tyr34 and Tyr56), two residues that are only partially exposed to solvent (Asn29 and Val70), and three residues that have been proposed to be at the dimer-dimer interface formed when gene V protein binds to nucleic acids (Glu40, Tyr41 and Arg82).

This phase report is the last part of a three-part phase report describing the results of field work conducted in 1992 at this operable unit. Phase Report 1A, issued on 14 June l993, summarized site geologic characterization activities. Phase report 1B, issued on 28 January 1994, included an assessment of site-wide surface soil background, airborne emissions deposition, and contamination in the locations of two former air filtration buildings. The investigations assessed in Phase Report 1C include field radiation surveys and surface and near-surface sampling to characterize potential contamination at 25 outfalls and septic systems listed as SWMUs in the RFI work plan. Based on the RFI data, it is recommended that no further action is warranted for 8 SWMUs and further action is recommended for 3 SWMUs addressed in this phase report. For 14 SWMUs which represent no immediate threat to human health or environment, deferral of further action/no further action decisions is recommended until outstanding analytical data are received, sampling of adjacent SWMUs is completed, or decisions are made about the baseline risk assessment approach.

Identical (super 3) He concentrations in coexisting olivine and clinopyroxene confirm that these two minerals have very similar production rates. A cosmogenic (super 3) He date of 57 ka on another flow is concordant with a U-series date and is younger than two K-Ar dates, suggesting that this flow contains excess (super 40) Ar. This excess (super 40) Ar is also evident in gases released by vacuum crushing of olivine-clinopyroxene fractions from all three flows.

Analyses of fluid inclusion volatiles are compared to those of the geothermal fluids. The results indicate that analyses of N (sub 2) -Ar-He in fluid inclusions can give accurate analyses of these species in the depositing fluids. Ratios of these species differentiate between shallow circulating meteoric fluids and those geothermal systems that do not have these components. N (sub 2) -Ar-He ratios in fluid inclusions indicate their origin from meteoric, crustal and magmatic sources and mixing of two of these sources. Other potential applications of these ratios are discussed.

The large response is attributed to structural discontinuities in rock such as microcracks and grain boundaries. The magnitude of the harmonics created by nonlinear interactions grows linearly with propagation distance in one-dimensional systems. In the earth, a large nonlinear response may be responsible for significant spectral alteration of a seismic wave at amplitudes and distances currently considered to be within the linear elastic regime. We argue, based on observations at ultrasonic frequencies, that the effect of nonlinear elasticity on seismic wave propagation may be large, and should be considered in modeling.

We start with the wave equation for an isotropic, homogeneous, elastic solid with cubic anharmonicity in the moduli, accounting for attenuation by introducing complex linear and nonlinear moduli. A hierarchy of equations, ordered in powers of the displacement field, is developed. Using a Green function technique, we solve this set of equations systematically for the displacement field at distance x from the source. We examine the influence of propagation distance, source frequency spectrum, source displacement amplitude, attenuation, and nonlinear coefficient on the spectrum of a propagating wave. The displacement field for various source functions is calculated using parameters typical of rocks. Copyright 1994 by the American Geophysical Union.

This approach addresses small, medium, & large business in an integrated fashion in terms of nine sectors of economic competitiveness. Methods for acquiring & utilizing technology & accessing government markets are proposed. A unique method for obtaining self-sufficiency & growth is developed. The presented model leverages federal investments into an independent & self-sufficient, privately funded partnership. This type of entrepreneurial approach to public-private initiatives is expected to lead to a higher rate of return on public investment. 1 Table, 2 Figures. Adapted from the source document.

Traditional alpha detectors are designed to detect alpha particles directly and must be passed slowly within 3 cm of an alpha source to operate effectively. LRAD detectors collect the ions created from alpha interaction with air. Therefore, they are better able to monitor equipment and complex surfaces and can be operated at a much greater distance from an alpha source than traditional alpha detectors. Furthermore, because LRAD detectors remain stationary during monitoring, they are less subject to operator error than traditional alpha detectors. This paper will discuss the basic operation as well as recent advances that have been made to the electrostatic LRAD.

The upwarp was generated at a slabless window trailing the northward-moving Mendocino triple junction. The geothermal area lies immediately east of the Rodgers Creek rather than the San Andreas fault because of a transform jump in progress. Decompression melting of the mantle has led to basaltic underplating, and crustal anatexis. The high heat flow is due to conduction through a thin lithosphere and the latent heat of solidifying basalt, while the uniformity is due to the distribution of sources over a wide area of large flatlying sills, The Hot Dry Rock resource has heat flow exceeding 4 HFU over an area exceeding 800 km2.

The instrumentation to be built will be used for field-screening of soils. Data quality is expected to be suitable for this purpose. The data presented in this report were acquired to demonstrate the detection limits for laser-induced breakdown spectroscopy (LIBS) of soils using instrument parameters suitable for fieldable instrumentation. The data are not expected to be the best achievable with the high pulse energies available in laboratory lasers. The report presents work to date on the detection limits for several elements in soils using LIBS. The elements targeted in the Technical Task Plan are antimony, arsenic, beryllium, cadmium, chromium, lead, selenium, and zirconium. Data for these elements are presented in this report. Also included are other data of interest to potential customers for the portable LIBS apparatus. These data are for barium, mercury, cesium and strontium. Data for uranium and thorium will be acquired during the tasks geared toward mixed waste characterization.

Their sessile nature requires that plants adapt to environmental changes by biochemical and molecular means. In principle, it is possible to develop a monitoring capability based on expression of any gene that is activated by specific environmental conditions. First year Department of Defense Strategic Environmental Research and Development program funding has enabled us to demonstrate the feasibility of using plants to monitor movement of TNT in the biosphere. We have identified plant genes activated upon exposure to TNT and cloned portions of these genes. Partial gene sequences will allow design of DNA probes that measure TNT-induced gene activity. These will be used to develop sensitive exposure assays that monitor gene expression in plants growing in environments contaminated with explosives.

After many months of investigation and proposals for repair of the facility, it became evident that it would be far more advantageous to the engineering community to remove those components of the centrifuge that were undamaged to the Davis campus and replace the drive system completely. The large centrifuge had cost over 2 million dollars to build, and it would have been irresponsible to simply scrap it. Recognizing this fact, funds were solicited and received from various sources, and Beam Engineering Inc. was contracted to design and construct the centrifuge at its new location. The University of California contributed a quarter of a million dollars and Tyndall Air Force Base, through Los Alamos National Laboratory, contributed $140,000. There were funds also contributed by LANL, LLNL, US Navy and NSF. The first stage in the phased development of the newly located centrifuge is nearing completion, which prompts the writing of this report. By the time that this report reaches the reader the first runs of the centrifuge will have been completed. The present report describes the present capability of the centrifuge and the plans for upgrading as time goes on. Several pilot studies were carried out. The experiments involved (1) the effects of nearby explosions on buried thin walled containers and (2) the advection and dispersion of toxic waste water through soils.

A number of different surface features were found to be characteristic of the native surface. Even surfaces freshly exposed by crushing larger crystals were found to have a pebbly surface texture caused by the presence of thin coatings of what might be surface precipitates. This finding is interpreted as evidence for previous exposure to water, probably through an extensive network of microfractures. Surface reactions on the goethite crystals were studied by AFM at size resolutions ranging from microns to atomic resolution before, during, and after reaction with distilled water and 0.1N HCl. Immediate and extensive surface reconfiguration occurred on contact with water. In one case, after equilibration with water for 3 days, surface reprecipitation, etching and pitting were observed. Atomic resolution images taken under water were found to be disordered. The result of surface reaction was generally to increase the surface area substantially through the extension of surface platelet arrays, present prior to reaction. This work is being done in support of the site characterization project at Yucca Mountain.

The monitor is a photoacoustic radiometer (PAR) controlled by an on-board, programmable microprocessor. The measurements determine the extent and location of the vapor plume in the subsurface. At least twelve wells surrounding the sources are measured quarterly. The sources are located in former liquid chemical waste disposal pits and shafts at Los Alamos National Laboratory. The primary constituents of the plume are 1,1,1 trichloroethane (TCA), trichloroethene (TCE), and tetrachloroethene or perchloroethene or perchloroethene (PCE). Four quarters of data are presented for TCA. All were used primarily as solvents and degreasers. Previously the composition of the vapor plume was determined by Gas Chromatography Mass Spectrometer GCMS methods. Photoacoustic radiometry and gas chromatography are discussed giving the advantages and disadvantages of each method, although in this program they are basically complementary. Gas chromatography is a more qualitative method to determine which analytes are present and the approximate concentration. Photoacoustic radiometry, to function well, requires foreknowledge of constituents and serves best to determine how much is present. Measurements are quicker and more direct with photoacoustic methods. Once the constituents to be measured are known, the cost to monitor is much less using photoacoustics, and the results are available more quickly.

We have a picture of intracaldera activity consisting of intermittent hydrovolcanic eruptions within a caldera lake for the lower third of the Creede Formation, and both magmatic and hydrovolcanic ash eruptions throughout the top two-thirds. Most of the ash deposits interbedded with the moat sedimentary rocks are extremely fine-grained. Ash fallout into the moat lake and unconsolidated ash eroded from caldera walls and the slopes of the resurgent dome were deposited over stream delta distributaries within relatively shallow water in the northwestern moat, and in deeper waters of the northern moat, where the caldera was intersected by a graben. Interbedded with ash beds and tuffaceous siltstones are coarse-grained turbidites from adjacent steep slopes and travertine from fissure ridges adjacent to the moat. Sedimentation rates and provenance for clastic sediments are linked to the frequent volcanic activity in and near the caldera; nearly all of the Creede Formation sedimentary rocks are tuffaceous.

This common genesis suggests that paleoenvironmental information, as well as the timing and pathways of past recharge episodes, might be obtained from studies of the deposits in both the calcretes and the unsaturated fractures. Chemical and isotopic modification of calcite-precipitating fluids appears to begin at the surface, largely under the influence of plant roots and their decay products. Chemical characteristics of the deeper calcites are either initiated or largely defined within the first few meters of fluid migration into the unsaturated tuffs beneath the calcretes. However, petrographic and isotopic data indicate a very unique low-delta (super 13) C microenvironment that is localized at the upper surfaces of the calcretes. These surfaces form an interface in the soil horizon where infiltration may pond above the underlying carbonate "plug". In order to decipher the chemistry and petrology of past recharge events, it is important to first understand microenvironments such as this that contribute to mineral precipitation/dissolution events in the pedogenic environment.

Reductive approaches for uranium decontamination have been limited to removing soluble uranium from solutions by formation of U (super 4+) which readily hydrolyses and precipitates. As part of the Uranium in Soils Integrated Demonstration, we have developed a reductive approach to solubilization of uranium from contaminated soils which employs reduction to destabilize U(VI) solid and sorbed species, and strong chelators for U(IV) to prevent hydrolysis and solubilize the reduced from. This strategy has particular application to sites where the uranium is present primarily as intractable U(VI) phases and where high fractions of the contamination must be removed to meet regulatory requirements.

HGMS uses large magnetic field gradients to separate ferromagnetic and paramagnetic particles from diamagnetic host materials. The technology relies only on physical properties, and therefore separations can be achieved while producing a minimum of secondary waste. Actinide and fission product wastes within the DOE weapons complex pose challenging problems for environmental remediation. Because the majority of actinide complexes and many fission products are paramagnetic, while most host materials are diamagnetic, HGMS can be used to concentrate the contaminants into a low volume waste stream. The authors are currently developing HGMS for applications to soil decontamination, liquid waste treatment, underground storage tank waste treatment, and actinide chemical processing residue concentration. Application of HGMS usually involves passing a slurry of the contaminated mixture through a magnetized volume. Field gradients are produced in the magnetized volume by a ferromagnetic matrix material, such as steel wool, expanded metal, iron shot, or nickel foam. The matrix fibers become trapping sites for ferromagnetic and paramagnetic particles in the host material. The particles with a positive susceptibility are attracted toward an increasing magnetic field gradient and can be extracted from diamagnetic particles, which react in the opposite direction, moving away from the areas of high field gradients. The extracted paramagnetic contaminants are flushed from the matrix fibers when the magnetic field is reduced to zero or when the matrix canister is removed from the magnetic field. Results are discussed for the removal of uranium trioxide from water, PuO(sub 2), U, and Pu from various soils (Fernald, Nevada Test Site), and the waste water treatment of Pu and Am isotopes using HGMS.

Fracture coatings in the Paintbrush Group provide information on potential flow paths above the water table both toward and away from the potential repository and provide information on the distribution of fracture-lining minerals needed to model thermal effects of waste emplacement. Fracture coatings within the predominantly non-zeolitic Paintbrush Group vary both with depth and laterally across Yucca Mountain, whereas fracture coatings in tuffs below the Paintbrush Group are related to the mineralogy of the tuffs and follow a consistent pattern of distribution with predominantly quartz, calcite, and manganese oxides in the devitrified intervals and mordenite and clinoptilolite in the zeolitic intervals. The zeolites stellerite and heulandite are more abundant in fractures in the Topopah Spring Tuff in drill holes USW G-1 and UE-25 a#1, located along Drill Hole Wash (at the northern end of Yucca Mountain) than in core from other parts of Yucca Mountain. Buesch et al. (2) present evidence for a complex fault system along Drill Hole Wash. To investigate the possibility that the abundant fracture-lining zeolites in USW G-1 and UE-25 a#1 are related to the Drill Hole Wash fault, the Topopah Spring Tuff was examined in drill cores from USW UZ-14, USW G-1, USW NRG-7/7a, and UE-25 a#1.

One scenario by which such transport could occur involves water leaving the storage area and carrying radioactive particulates of colloidal size. The colloids could move along the gas-liquid interface in partially filled fractures within the vadose zone. It should be possible to check the reality of this proposed scenario by examining "anthropogenic analogs" of the repository. These are sites of nuclear tests conducted in unsaturated tuff at the Nevada Test Site (NTS). We propose to drill under one or more such sites to determine if radionuclides have moved from their original confinement in the puddle-glass at the bottom of the cavity. This document examines the characteristics of an ideal test site for such a study, suggests several possible locations that have some of the desired characteristics, and recommends one of these sites for the proposed drilling.

Alpha radiation is an excellent indicator of the presence of many isotopes (such as Pu (super 239) ) which are otherwise difficult to observe. However, traditional fieldable alpha detectors have been hampered by the short range of alpha particles in air and in detector windows. We have developed an alpha detection technology that avoids the problems mentioned above. In a monitor using the long-range alpha detector (LRAD) technology, we detect the ion pairs produced by an alpha particle's interaction with air rather than the particles themselves. In this paper, we discuss several applications to air and soil monitoring as well as potentially contaminated building surfaces and process equipment.

One important aspect of regional seismic monitoring involves the discrimination of nuclear explosions from other sources such as earthquakes and mining events (e.g. industrial explosions and rockbursts). In this paper, we review earthquake/nuclear explosion discrimination studies in the western US using broad-band seismic data. These studies are important because they are the only ones involving nuclear explosions and other sources in a single geophysical region having excellent ground truth information and a substantial historic database. Additionally, because of access to information from the NTS, much can be learned about the physical basis of regional discriminants. Using multivariate discrimination techniques, it was found, that approximately 96% of the events analyzed could be correctly identified down to about magnitude 3.5. Most of the events misidentified were recorded with poor signal-to-noise ratio at only a minimal number of stations. However, a few well-recorded events were misclassified for one or more discriminants. Examples of detailed analysis of a missed violation (nuclear explosion that looks like an earthquake) and a false alarm (naturally occurring event that looks like an explosion) are illustrated.

Relative crustal residence ages can be calculated from variations in (super 226) Ra/ (super 230) Th and (super 231) Pa/ (super 235) U activity ratios for axial lavas, if (1) mantle sources and melting are uniform, and mantle transfer times are constant or rapid for axial N-MORB, and (2) (super 231) Pa/ (super 235) U and (super 226) Ra/ (super 230) Th in the melt are unaffected by shallow level fractional crystallization. Uniform Th, Sr, and Nd isotopic systematics and incompatible element ratios for N-MORB along the 9-10 degrees N segment indicate that mantle sources and transfer times are similar. In addition, estimated bulk solid/melt partition coefficients for U, Th, and Pa are small, hence effects of fractional crystallization on (super 231) Pa/ (super 235) U ratios for the melt are expected to be negligible. However, fractional crystallization of plagioclase in the AMC would lower (super 226) Ra/ (super 230) Th ratios in the melt and produce a positive bias in (super 226) Ra crustal residence ages for fractionated lavas.

The isotopic signatures help identify element origin and separate naturally occurring or background contributions from local anthropogenic sources. Typical sample sizes for processing are 2 liters of water, 1-10 grams of sediment, and 1-20 grams of soil. Measurement limits for Pu, Am, and Np are <1X18 (super 8) atoms, and for U are <2.5X10 (super 12) atoms. For isotopic signatures, <5X10 (super 8) atoms of Pu, Am, and Np are necessary, and 8X10 (super 12) atoms of U are required. Of potential interest to the IAEA is the incorporation of these techniques into their Safeguards Analytical Laboratory for environmental sampling. Studies made of surface waters, sediments and soils from the Rocky Flats Plant (RFP) in Colorado, US, are used as examples of this methodology. These studies showed that, although plant boundary actinide concentrations approached, on the downstream side, natural or background levels, isotopic signatures characteristic of plant operations were still discernible.

The results of the test were positive. During 104 hours of monitoring, 572 discrete events were recorded which have been identified as shear-failure microearthquakes. Reservoir microseismicity was detected at large distances (1000 m) from the monitor borehole and at rates (>5 events per hour) which may allow practical characterization of the reservoir rock and overburden deformation induced by reservoir pressure changes.

The chosen organic acids do affect the potential mobility of Pd through the formation of complexes and these ligands can compete with much higher concentrations of a ligandsuch as chloride. Flocculation of fulvic/humic acids may also provide an effective means of immobilizing Pd. The results are applied to exploration geochemistry and radwaste disposal.

Such information is important for predicting the amount of heat energy that may be extracted from geothermal reservoir.A fractured zone was created at the Los Alamos Hot Dry Rock Reservoir in north-central New Mexico within otherwise impermeable basement rock by injecting 21 000 m (super 3) of water into a borehole under high pressure at a depth of 3.5 km. Induced microearthquakes were observed using four borehole seismometers. The P-wave and S-wave arrival times have been inverted to find the 3-D velocity structures and the microearthquake locations and origin times. The inversion was implemented using the separation of parameters technique, and constraints were incorporated to require smooth velocity structures and to restrict the velocities within the fractured region to be less than or equal to the velocities of the unfractured basement rock. The rms arrival time residuals decrease by 11-15 percent during the joint hypocenter-velocity inversion. The average change in the microearthquake locations is 20-27 m, depending on the smoothing parameter used. Tests with synthetic data imply that the absolute locations may improve by as much as 35 percent, while the relative locations may improve by 40 percent. The general S-wave velocity patterns are reliable, but the absolute velocity values are not uniquely determined. However, studies of inversions using various degrees of smoothing suggest that the S-wave velocities decrease by at least 13 percent in the most intensely fractured regions of the reservoir. The P-wave velocities are poorly constrained because the P-wave traveltime perturbations caused by the fluid-filled fractures are small compared to the arrival time noise level. The significant difference in the relative signal-to-noise levels of the P-wave and S-wave arrival time data, coupled with the limited ray coverage, can produce a bias in the computed V (sub P) /V (sub S) ratios, and corresponding systematic rotation of the microearthquake cluster. These adverse effects were greatly reduced by applying a V (sub P) /V (sub S) lower bound based on the V (sub P) /V (sub S) ratio of the unfractured basement rock.

Most of the ages are younger than expected and most of the dated basalts on the crestal plateau were erupted 0.5-2 km (some up to 4 km) outside the ASC. The magmatic zone is thus broader by up to 8 km than that of the present ASC. Lavas on the plateau need not have been erupted through the same system as that supplying magma to the ASC. Melts outside the ASC may thus have distinct parents, supplysystems and crustal residence times relative to axial lavas.

To improve the spatial coverage and resolution of the intrarift rotation, we analyzed the late Tertiary sediments within the exposed Espanola Basin for paleomagnetic rotations. From five sites broadly distributed across the rift, the amount of rotation varies from little on the eastern edge to over 20 degrees counterclockwise in the central and western rift. If interpreted as tectonic net rotation axes, the amount of rotation varies from 10 to 24 degrees . Gently northeast plunging net rotation axis orientations in the eastern part of the rift indicate dominantly extension-related deformation. Steeper axis inclinations near the center and western part of the rift and Embudo accommodation zone indicate the presence of increased horizontal shearing in these regions. The paleomagnetic data show that the north-central Rio Grande rift is not rotating as a unit but rather consists of a number of smaller independently, counterclockwise-rotating blocks.

The Albuquerque-Belen Basin is composed of two separate, opposite-facing, structurally complex basins linked by an accommodation zone. South of the Albuquerque-Belen Basin, the rift broadens southwestward around the Colorado Plateau. A zone of distributed sinistral shear at the margin of the plateau accommodated differential extension between the little-extended plateau and the half grabens (Milligan Gulch, La Jencia, and Socorro) of the rift. Extension in the latter accommodation zone is expressed in the sedimentary cover rocks by north-striking, high-angle normal faults and a segmented, northeast-striking, sinistral fault. The Ladron horst and the Lucero uplift border the rift on the western side of the Albuquerque-Belen Basin and were isostatically uplifted as a result of tectonic denudation along the bounding faults of adjacent half grabens. Footwall structures include folded Paleozoic and Mesozoic rocks, intrabed thrust faults, and high-angle shear zones. We present new models for the Neogene evolution of the central Rio Grande rift and integrate contractional and extensional structures previously attributed to different stress regimes. Many of the structures in the central Rio Grande rift previously attributed to Laramide compression can be adequately explained by late Tertiary extension.

Essentially, waste stream polishing to remove final traces of plutonium and hazardous chemical constituents could be achieved through process modifications, the use of alternative chemicals and sorbents for residue removal, acid recycling and the use of a variety of waste polishing techniques. In an example, high magnetic-field separation of paramagnetic actinide particulates and freeze-drying were promising for the removal of residual amounts of plutonium as fine colloidal particles in liquid streams which could not be removed by conventional ion exchange or filtration processes.

Environmental concerns have recently focused attention on the numerous fractures in the Bandelier Tuff, the series of volcanic rock units that make up most of the plateau. These fractures have come into question as possible conduits for transport of contaminants downward through the tuff. This, study arose out of a need to evaluate the potential for contaminant transport in the fractures. Because the fractures are typically filled, or partially filled, with soil-like material, and appear to be physically continuous with the soils on the surface of the Pajarito Plateau, it was decided to approach the question of the fractures from a soil genesis and morphology standpoint. Specifically, it was believed that soil characterization techniques, including soil micromorphological and mineralogical analyses, could provide information about the dominant processes (past and present) acting in the soils and fractures. The specific objectives of this research were to investigate: (1) the physical, mineralogical and chemical nature of fracture-filling materials in the Bandelier Tuff, as well as associated surface soils; (2) the relationships among fracture-fills, tuff bedrock, and surface soils of the Pajarito Plateau; (3) the processes responsible for the development of the fracture-fills; and (4) the likely sequence of events leading to the present morphology of the soils and fracture-fills.

At or very close to the D-C boundary, there exists a geographically widespread black-shale interval, and Ir abundances reach anomalous maxima of 0.148 ppb (Montagne Noire, France), 0.138 ppb (Alberta, Canada) 0.140 ppb (Carnic Alps, Austria), 0.156 ppb (Guangxi, China), 0.258 ppb (Guizhou, China), and 0.250 ppb (Oklahoma). The discovery of global D-C Ir anomalies argues for an impact-extinction model. However, nonchondritic ratios of Ir to other important elements and a lack of physical evidence (shocked quartz, microtektites) do not support such a scenario. The fact that all Ir abundance maxima are at sharp redox boundaries in these sections leads us to conclude that the Ir anomalies likely resulted from a sudden change in paleo-redox conditions during deposition and/or early diagenesis.

Unit-cell parameters are: a = 5.1535(3) Aa, b = 8.9419(5) Aa, c = 7.3906(4) Aa, alpha = 91.926(2) degrees , beta = 105.046(2) degrees , gamma = 89.797(2) degrees , and V = 328.70(5) Aa (super 3) . Unit-cell parameters show that most of the thermal contraction occurred along the [001] direction, apparently due to a decrease in the interlayer distance. The non-H structure is very similar to published C1 structures, considering the low temperature of data collection, but the H atom positions are distinct. The inner OH group is essentially in the plane of the layers, and the inner-surface OH groups make angles of 60 degrees -73 degrees with the (001) plane. Difference-Fourier maps show minor anisotropy of the inner-OH group in the [001] direction, but the inner-surface OH groups appear to have their largest vibrational (or positional disorder) component parallel to the layers. Although no data indicate a split position of any of the H sites in kaolinite, there is support for limited random positional disorder of the H atoms. However, these data provided no support for a space group symmetry lower than C1.

The dehydration of this vitrophyre was studied by thermogravimetric analysis (TGA) and by isothermal heating at 50 degrees , 100 degrees , 200 degrees , and 400 degrees C for 3.4 years followed by 1.1 years of rehydration at high controlled humidity ( approximately 79% relative humidity). No crystallization of the glass was observed in long-term dehydration or rehydration; the only observed chemical alteration was loss of up to 60% of original fluorine. TGA studies show a characteristic two-stage dehydration of the vitrophyre, with two-thirds to three-fourths weight loss occurring most rapidly at temperatures ranging from 278 degrees to 346 degrees C in 10 degrees C/min heating experiments. The remaining water, about 1% in all of the vitrophyre samples studied regardless of total water content, is lost only on second-stage heating to temperatures above 650 degrees C. Long-term isothermal heating at < or =400 degrees C releases only the first-stage water. Loss of essentially all first-stage water occurred in less than 1 hour at 400 degrees C; proportionately lower losses were obtained at 200 degrees and 100 degrees C. Small (0.2%) water loss occurred in the 50 degrees C experiment. A time-temperature-dehydration diagram generated from the isothermal heating data shows a clustering of dehydration contours that are the equilibrium equivalent of the rapid first-stage water loss in dynamic TGA experiments. These dry-heating experiments provide an end-member characterization of glass transformations for comparison with water-saturated heating experiments in which glass alteration is prominent.

These four examples are intended to provide theoretical guidance for determining the style of convection that is occurring in Earth's mantle. An impermeable interface between the upper and lower converting shells in the two-layer solutions is placed at a depth of 670 km to coincide with the mantle seismic discontinuity that divides the upper and lower mantle. The interface results in an internal thermal boundary layer that raises the mean temperature in the lower shell by about 1400 K compared to the whole-layer solutions. The patterns of convection in the upper part of the whole-layer solutions are dominated by narrow arcuate sheetlike downflows in a background of weak upflow. In contrast, the upper shells of the two-layer solutions have complicated networks of convective rolls with the upflows and downflows having very similar structure. The structure of convection in the lower shells is similar to that in the lower part of the whole-layer solutions. An increase (decrease) in the viscosity in the lower (upper) shell decreases (increases) the convective velocity in the lower (upper) shell and increases (decreases) the horizontal scale in the lower (upper) shell. The upper and lower shells are viscously coupled at the 670-km interface when viscosity is the same in the two shells. However, when viscosity in the lower shell is 30 times greater than that in the upper shell, the coupling is partially viscous and partially thermal. Based on the horizontal structure of subduction zones on Earth's surface and on tomographic images of temperature variations in Earth's mantle, we conclude that the style of convection in Earth's mantle is more like that of the whole-mantle models.

The magnetotelluric (MT) method is applied to field variations at periods between a few seconds and 16 hours and yields penetration depths between a few km and 600 km. This is an extension of both methods, using additional D (sub St) -data for MT and additional S (sub q) -data for GM. In application to field data from Western Europe the resulting overlap of the target depths includes an electrical conductivity increase from 10 (super -2) S/m at 300 km to 1 S/m at 700 km depth while a single conductivity jump at either 400, 500 or 700 km cannot explain the broadband data. Although the olivine to spinel transition is a possible explanation of the conductivity enhancement at 400 km depth, another mineralogy could also occur. This conductivity increase has not been resolved in other sub-continental profiles and lateral heterogeneity is probable in this depth range. Copyright 1993 by the American Geophysical Union.

At a latitude corresponding roughly to, but slightly less than, the inferred tilt of the coronal streamer belt and embedded heliospheric current sheet, the strong forward shocks commonly associated with CIRs at lower latitudes disappeared almost entirely; however, the reverse shocks associated with these CIRs persisted to latitudes 10 degree above the streamer belt. Systematic meridional flow deflections observed in association with the forward and reverse waves bounding the CIRs demonstrate that the above effect is the result of the fact that the forward waves propagate to lower latitudes and the reverse waves to higher latitudes with increasing heliocentric distance. These observational results are in excellent agreement with the predictions of a three-dimensional model of corotating solar wind flows that originate in a tilted dipole geometry back at the Sun.

The model was selected primarily for its ability to simulate the significant mechanisms that may affect transport of contaminants through the vadose zone at the TA-73 landfill, including non-isothermal flow through fractured media. TOUGH2 is the best documented, verified, and validated model capable of performing the required simulations. The sensitivity analyses that were performed and describes in this report identified the input parameters that the selected numerical model is most sensitive to. The input parameters analyzed were saturated hydraulic conductivity, van Genuchten (alpha) and n, residual and saturated moisture contents, infiltration rate, fracture spacing and permeability, atmospheric pressure, and temperature. The sensitivity analyses were performed using a model grid that was designed to incorporate the regions in the landfill vicinity where contaminant transport is likely to occur and where the physical processes affecting flow and transport are the most dynamic. The sensitivity analyses performed suggest that the model is quite sensitive to a number of input parameters, including saturated hydraulic conductivity, the van Genuchten parameters (alpha) and n (for both the tuff matrix and fractures), fracture density and aperture, and atmospheric pressure. The results indicate that additional site-specific hydraulic properties and fracture data should be obtained before attempting to perform predictive, numerical simulations of gas- and liquid-phase flow beneath the landfill.

Our goal is to determine the limits in information content of remotely sensed neutrons and gamma rays in delineating the abundance of ground ice and its distribution with depth. Such ice is expected based on simple theoretical calculations of the H (sub 2) O environment of the martian surface and atmosphere. We find it produces a marked redistribution of neutrons with depth. Neutron-capture gamma ray production closely follows the flux of thermal neutrons and is likewise redistributed with depth. Calculated effects at Mars mapping orbit are sufficiently large that, if ice is present at the depths and in the quantities expected, the MOGRS should provide a robust detection of its presence. Although the information content of gamma rays and neutrons alone is not sufficient to define the many parameters needed to specify its abundance and emplacement below the surface, their combined use might allow separation of the ice abundance from its vertical distribution within the regolith.

In July 1992 while travelling south at 13 degree S and 5.3 AU, Ulysses encountered a recurrent high-speed stream, that may also have been observed at IMP 8. The stream has been observed a total of 14 times, once in each solar rotation through June 1993 at 34 degree S. The source of the high-speed stream is an equatorward extension of the south polar coronal hole. From July 1992 through June 1993, averages of solar wind peak speed increased while density decreased with heliographic latitude. Both the stream and a low-speed, high-density flow, presumably associated with the heliomagnetic (coronal) streamer belt encircling the heliomagnetic equator, crossed Ulysses with the solar rotation period until April 1993 when the spacecraft was at 29 degree S heliographic latitude. After this time, as the spacecraft climbed to higher latitudes, the central portion of the streamer belt with lowest speed and highest density disappeared. Therefore, at its maximum inclination, the belt was tilted at 29 degree to the heliographic equator at this point in the solar cycle.

The results of this mapping are presented. Contacts between volcanic units and geomorphic features were field checked, incorporating data from eight field trenches as well as several exposures along Black Tank Wash. Within each of the eight trenches, logs were measured and stratigraphic sections were described. These data indicate that three, temporally separate volcanic eruptions occurred at the Black Tank center. The field evidence for significant time breaks between each stratigraphic unit is the presence of soil and pavement-bounded unconformities.

Binary mixtures (most 50:50 by weight) of corundum with quartz, hematite, ilmenite, magnetite, biotite, analcite, mordenite, or clinoptilolite were analysed, using digital powder XRD data. In addition, a suite of standard mixtures of hematite and corundum, a natural feldspar mixture, the G-1 standard granite, two natural bauxite samples and a mixture of biogenic carbonate minerals were also analysed.

With appropriate downstream boundary conditions there results a more coherent and more strongly damped trailing magnetic wave with fewer back-streaming ions than with the hybrid model under the same conditions. Evidently, kinetic effects cause a more equal sharing of shock-induced entropy increases between ions and electrons, which results in lower ion temperatures downstream and greater electron energy transport from downstream to upstream.

Landslides failed along mechanically weak rocks in the Santa Fe Group, within the Puye Formation, or in Pliocene alluvial and lacustrine units. The landslides are mainly of early or middle Pleistocene age. The toe area of at least,one slump complex has been active in the late Pleistocene, damming White Rock Canyon near the mouth of Water Canyon. Lacustrine sediment that filled this lake, or series of lakes, to an elevation of at least 1710 m is preserved at a number of upstream sites, including a deposit near the Buckman townsite that exposes 30 m of lacustrine sediment. Charcoal collected at several sites has been submitted for (super 14) C dating. Landslides, however, probably do not represent a significant short-term threat to the material disposal areas at TA-33. Bedrock that lies beneath the TA-33 mesa is relatively stable, the mesa shows no signs of incipient failure, and past periods of slide activity were responses to rapid downcutting of the Rio Grande and climate change, probably over periods of several decades, at least. Rockfall and headward erosion of gullies do not represent significant decadal hazards on canyon rims near TA-33. Gully migration near MDA-K is a potential threat, but the gullies were not examined in detail. A system of north-trending faults, at least one of which displays Pleistocene activity, bisects the TA-33 mesa. If these faults are capable of producing significant seismic shaking, generalizations about landslide and rockfall hazards must be reevaluated.

MDA L has been used for disposal of volatile organic compounds (VOCs) and MDA G (comprising sub-areas G-1 through G-8) for disposal of both VOCs and radioactive waste; MDA I has reportedly been used for disposal of waste without either of these contaminants. All three of the sites are currently active. Figure 1 shows the location of the three MDAs within Technical Area 54 of operable Unit 1148. The purpose of the EMFLUX (super R) Soil-Gas Survey was to determine the presence, identities, and relative strengths of contaminants within the three areas of LANL investigated. Quadrel understands that this information will be used in Phase-I assessment of these areas to determine flux rates of VOCs emanating from the ground.

Trilobites and conodonts indicate a profound extinction at the end of the Ordovician, which is constrained stratigraphically within a < 60 cm interval, coinciding with the maximum shallowing probably caused by a glacioeustatic regression induced by the late Ordovician Gondwanan glaciation. The extinction is also signalled by the change in carbonate delta (super 13) C. Iridium abundances (< 0.051 ppb) in the extinction interval are low and provide no evidence for an impact; the highest Ir values occur associated with reduced sedimentation in a condensed horizon. Cerium anomalies indicate a short period of basin ventilation in the otherwise anoxic Selwyn Basin. The extinction occurred during this ventilation, which was probably caused by the cold climate during the glaciation. The ventilation may have triggered upwelling of deep water through vertical advection, bringing up toxic material, poisoning the shallow-water photic zone and causing the extinction.

It is observed that the abundances of Ir and other siderophile and chalcophile elements (e.g., Co, Cr, As, Mo, Sb and V) show elevated values in the extinction horizon at the base of the graptolite persculptus Zone, which corresponds to the stratigraphic level for the local systemic boundary in China between the "Ordovician" and "Silurian". Iridium abundances show maxima at this extinction level in three of the four sections analyzed with varying strength, 230 ppT at Yichang, 92 ppT at Jinxian, and 88 ppT at Youyang (but 50 ppT at Xiushan). These geochemical patterns appear to be of global significance, since similar geochemical anomalies (including weak Ir anomaly) were also recorded at about the same stratigraphic level in many other sections previously studied in Quebec, Yukon, Arctic and Northwest Territories, Canada, and Scotland. Although impact by a comet with low platinum group element abundances could have been responsible for the geochemical anomalies, we find it is most plausible to attribute the geochemical signal to the effects of a lower sedimentation rate and reducing water conditions at this horizon, the beginning of a rapid transgression induced by rapid melting of the ice caps on Gondwana. Carbon isotope excursions in organic material at Yichang, together with other carbon isotope data from central Sweden, northwestern Canada, Latvia, Quebec and Wisconsin, suggest that, after a period of decreasing atmospheric and marine pCO (sub 2) in the latest Ordovician (the Hirnantian), a sudden, large pCO (sub 2) increase in the ocean and atmosphere may have occurred at the extinction horizon at the base of the persculptus Zone. A greenhouse effect might have existed for a short time. What triggered such a sudden pCO (sub 2) increase is uncertain, but a rapid CO (sub 2) degassing caused by volcanism, tectonics, and/or extraterrestrial impact could have been responsible.

Hot spring waters are enriched in delta (super 18) O by 400 degrees C fumarole condensate collected from the central crater in 1980, condensate samples collected on the dome, and cold meteoric and hot spring waters. This indicates that mixing occurs between local meteoric water and magmatic water degassing from the dacite dome. There is 30-70% magmatic water present in the dome fumarole discharges and 10% has been added to the waters of the hydrothermal system. Relations between Cl, SO (sub 4) , and HCO (sub 3) indicate that the hot spring waters are immature volcanic waters formed by reaction of rocks with waters generated by absorption of acidic volcanic fluids. In addition, the B/Cl ratios of the spring waters are similar to those of the fumarole condensates, values of delta (super 13) C in the HCO (sub 3) of the hot springs are similar to the magmatic value at MSH, and the (super 3) He/ (super 4) He ratio, relative to air, in a hot spring water is 5.7, suggesting a magmatic origin for this component.

The test samples were initially loaded to a relatively small fraction of the uniaxial compressive failure stress, and allowed to creep; then the stress was increased periodically until creep failure occurred. The strain versus time creep curves exhibit the classical phenomenological phases of primary, secondary, and tertiary creep analogous to those for ductile metals, although the tuffs deform by dilational microcracking and fail by brittle fracture. Mechanical "steady state" or secondary creep strain rates as low as 1 X 10 (super -10) s (super -1) were observed in the tests. Tertiary creep axial failure strains averaged about 6 X 10 (super -3) . The early, water saturation phases of the tests are characterized by large hydration swelling strains associated with water absorption by the zeolite minerals in the tuffs. The hydration was often incomplete after one month of immersion, and slow, continued hydration affected the creep curves so that the samples appeared to lengthen against axial differential stresses as high as 55 MPa. This strong chemical-mechanical coupling suggests that in situ hydration state changes could generate stresses of similar magnitude. Copyright 1993 by the American Geophysical Union.

These experiments were designed to provide quantitative evidence of important pore-scale displacement processes. A unique experimental approach using a two-dimensional synthetic porous medium (micromodel) and digital image analysis (DIA) enabled both measurement of three-fluid capillary pressure-saturation relationships and analysis of fluid behavior at the pore level. Experiments were pressure controlled, and were designed to mimic measurements typically performed on laboratory cores. Only quasi-static measurements were made, with a focus on capillary pressure-saturation relations. Different orders of fluid infiltration with respect to wettability were studied. DIA made it possible to obtain quantitative information about the experiments, including fluid saturations, saturation changes between pressure steps, and movement of apparently isolated fluids through films. The results provide insights into important pore-scale mechanisms and provide a basis for three-fluid pore-scale computations.

The halogen and sulfur content of the gas vary in a quasi-cyclical pattern possibly because of a heterogeneous distribution of volatiles in the Erebus magmatic system. The emission rates of HF and HCl have increased twofold since 1986 reaching 6 and 13.3 Gg yr (super -1) , respectively, in 1991, making Erebus an important contributor of halogens to the Antarctic atmosphere.

AN - 75910156; 8353836 AB - The acquisition of an extended lifespan and of neoplastic properties, including anchorage independence, ability to grow in low serum-containing media, morphological transformation, immortalization and tumorigenicity in nude mice were studied in 31 human fibroblast lineages transfected with plasmids containing the SV40 early genes. Plasmids were used that contained sequences for large T alone, or large T plus small t or large T plus small t plus the SV40 origin. Cells expressing large T antigen gradually acquired the ability to form colonies in low serum or to form anchorage-independent colonies. Large T antigen was sufficient to cause complete transformation to tumorigenicity if multi-step lineage evolution was obtained by prolonged serial passage and if in vivo progression was assisted by means of a gelatin sponge implantation technique. Cells derived from progressive tumors initiated in sponges showed enhanced tumorigenicity as measured by ability to obtain tumors without using sponges and with reduced latent period, higher incidence and with fewer cells inoculated. Multiple lineages of human fibroblasts have been converted to tumorigenicity without additional treatments such as transfection with activated oncogenes or exposure to carcinogens. These data, taken in conjunction with earlier studies showing that T antigen causes chromosome mutation preceding and accompanying the accumulation of the neoplastic phenotype, suggests that the T protein drives the transformation process by acting as a mutagen and cells with growth advantages were selected for in vitro and in vivo. With the possible exception of morphological transformation, the presence or absence of genes for small t and the SV40 origin were not critical for the process.

These darkly varnished, ancient colluvial deposits stand out in stark contrast to the underlying light-colored bedrock of volcanic tuffs, and they serve as minor divides between drainage channels on modern hillslopes. To demonstrate the antiquity of these stable hillslope features, six colluvial boulder deposits from Yucca Mountain, Nye County, Nevada, were dated by cation-ratio dating of rock varnish accreted on boulder surfaces. Estimated minimum ages of these boulder deposits range from 760 to 170 ka. Five additional older deposits on nearby Skull and Little Skull Mountains and Buckboard Mesa yielded cation-ratio minimum-age estimates of 1.38 Ma to 800 ka. An independent cosmogenic chlorine-36 surface exposure date was obtained on one deposit, which confirms an estimated early to middle Quaternary age. These deposits have provided the oldest age estimates for unconsolidated hillslope deposits in the southwestern United States. We suggest that the colluvial boulder deposits were produced during early and middle Pleistocene glacial/pluvial episodes and were stabilized during the transition to drier interglacial climates. By comparison to modern periglacial environments, winter minimum monthly temperatures of -3 to -5 degrees C were necessary to initiate freeze-thaw conditions of such vigor to physically weather relatively large volumes of large boulders from the upper hillslopes of the Yucca Mountain area. These conditions imply that early and middle Pleistocene glacial winter temperatures were at least 1 to 3 degrees C colder than existed during the last Pleistocene glacial episode and 7 to 9 degrees C colder than present. We conclude that at least several early and middle Pleistocene glacial episodes were colder, and perhaps wetter, than glacial episodes of the late Pleistocene in the southern Great Basin. Geomorphic processes necessary to form these colluvial boulder deposits are not active on modern hillslopes in the southern Great Basin. In addition, the lack of young, relatively unvarnished colluvial boulder deposits on these hillslopes suggests that boulder-forming conditions did not exist during the late Pleistocene in this region. Modern semiarid hillslope processes primarily erode colluvium during infrequent high-intensity storms. The preservation of old, thin hillslope deposits and the less-than-2-m incision by hillslope runoff adjacent to these deposits, however, indicate that extremely low denudation rates have occurred on resistant volcanic hillslopes in the southern Great Basin during Quaternary time.

Relative crustal contributions to large-volume rhyolite can be estimated by comparing the Nd isotopic composition of the rhyolite with the Nd isotopic characteristics of crust and mantle reservoirs associated with different continental basement age provinces. We have estimated the crustal contributions to 12 early Oligocene to Pleistocene rhyolite systems located throughout the Cordillera. We have determined that (1) crustal contributions to large-volume rhyolite systems decrease from the Oligocene to the Miocene, and (2) rhyolite systems younger than 20 Ma are dominated by mantle components. The crustal contributions to rhyolite systems may be controlled by system size and duration, crustal thickness, tectonic setting, crustal composition, crustal density, and crustal temperature. We conclude that regional cooling of the lower crust, which progressively limited the amount of crustal wallrock assimilated by rhyolite systems, is the only parameter that is consistent with geologic and geochemical data for rhyolite systems and the geologic evolution of the Cordillera. A quantitative model that relates the amount of crustal contribution to assimilation/recharge rates and the temperature of the crust indicates that lower-crustal temperatures would have to decrease about 300 degrees C between early Oligocene and early Miocene time to account for the decrease in crustal contributions.

AN - 50335630; 1993-023307 AB - Yucca Mountain, Nevada, is currently under investigation to determine its suitability as a potential host for the first U.S. high-level nuclear waste repository. Yucca Mountain is composed of a thick sequence of silicic volcanic tuffs and subordinate lavas which in some areas have been extensively altered to zeolite minerals. Since fractures may act as transport pathways or conduits for fluids moving through and away from a potential repository, the nature of the minerals lining the walls of fractures is of great importance. Mn-oxide minerals in particular are important since they show strong retardation capabilities for transuranic elements such as U, Np, Pu and Am. This study focused on the mineralogy, chemistry and distribution of the Mn-oxides at Yucca Mountain using X-ray diffraction and optical and electron microscopy. The major Mn-oxide minerals identified were aurorite, cryptomelane/hollandite/coronadite, lithiophorite, pyrolusite, rancieite and todorokite. Mn-oxide mineralogy appears to be controlled both by stratigraphy and by position relative to the static water level (SWL). For example, rancieite was found predominantly in the Paintbrush Tuff both above and below the SWL. Aurorite, pyrolusite, todorokite and the cryptomelane group minerals, although found in several stratigraphic units, occur only below the SWL. Additionally, mineral chemistry varies widely over short distances, suggesting that the chemical composition of the minerals must have been strongly influenced by local variations in water chemistry. Chemical analyses of the cryptomelane group minerals suggest the existence of at least partial solid solution between hollandite (Ba) and the isostructural minerals cryptomelane (K) and coronadite (Pb).

AN - 85244834; pmid-8262534 AB - Numerical simulation studies were performed using a multiple dipole source model and a spherical approximation of the head to examine how the resolution of simultaneously active neuromagnetic sources depends upon: 1) source modeling assumptions (i.e., number of assumed dipoles); 2) actual source parameters (e.g., location, orientation, and moment); and 3) measurement errors. Forward calculations were conducted for a series of source configurations in which the number of dipoles, specific dipole parameters, and noise levels were systematically varied. Simulated noisy field distributions were fit by multiple dipole models of increasing model order (1, 2, ..., 6 and alternative statistical approaches (i.e., percent of variance, reduced chi-square, and F-ratio) were compared for their effectiveness in determining adequate model order. Limits of spatial resolution were established for a variety of multi-source configurations and noise conditions. Implications for the analysis of empirical data are discussed.

The deposit lies in valleys and isolated watersheds, and in its medial and distal extent to the south, north and east of Naples, the Campanian pyroclastic current encountered mountains exceeding 1000 meters. Anisotropy of magnetic susceptibility (AMS) measurements indicate that the Campanian pyroclastic current (the transport system) traveled radially outward from the Phlegrean Fields area, but the ignimbrite-forming flow (the deposition system that developed from the base of the transport system) moved downslope from mountainsides to valleys, including slopes facing the eruption source, and flowed down drainage systems from intermontane basins. The Campanian pyroclastic current flowed approximately 35 km over the water of the Bay of Naples to deposit >43 m of ignimbrite on the south shore and also overtopped a 685-1000-m-high ridge of the Sorrento Peninsula to deposit more on the other side. The distribution of the ignimbrite and the measured flow directions suggest that the Campanian pyroclastic current moved across the landscape as an expanded (and therefore turbulent) decompressing flow rather than as a high-density, nonturbulent sheet-like current moving over mountains by momentum acquired by eruption column collapse. Strong expansion is corroborated by shard morphology that indicates derivation from highly inflated pumice and suggests vesicles must have been at least 80% by volume of the original magma.

The model erosion rates determined for different stratigraphic units within the Tshirege Member, upper Bandelier Tuff, vary from 0.1 cm/ka for the resistant unit to 1.1 cm/ka for the softer unit. Intermediate erosion rates are thought to indicate earlier age cover by post-tuff lithologies of different hardness. The geographic distribution of these intermediate rates allows an approximate determination of the extent of material now gone (stratigraphic ghosts). Periods of burial can be determined from (super 26) Al/ (super 10) Be ratios. For the Pajarito Plateau, burial most likely resulted from cover by soil and sediment held in place by vegetation. Our data allow us to model the duration and extent of thick forest cover, which today exists only at higher altitudes.

The non-hydrogen structure is essentially identical to published structures for dickite, but the hydrogen positions are distinct. The inner hydroxyl group is approximately parallel to the (001) plane, inclined by 1.3 degrees towards the tetrahedral sheet. Contrary to published low-temperature infrared (IR) spectra, there is no evidence that dickite possess lower symmetry at low temperatures although there is tentative evidence for statistical occupancy of H3 on more than one site. Low-temperature IR spectra of St. Claire and Wisconsin dickites do not show evidence for more than four hydroxyl groups and are consistent with the reported structure. Upon cooling from 300 to 15 K, the position of the OH3 stretching band increased from 3710 to 3731 cm (super -1) . This large, positive shift in frequency was attributed to the increase in the internuclear O-H3...O distance upon cooling. The frequency of the 3655 cm (super -1) band initially decreased by 2 cm (super -1) to 3653 cm (super -1) upon cooling from 300-125 K; however, the band increased in frequency by 1 cm (super -1) upon further cooling to 15 K. This unusual change in frequency upon cooling is consistent with the assignment of this band to OH2 and OH4. The position of the OH1 stretching band decreased from 3622 to 3620 cm (super -1) upon cooling, which was attributed, in part, to the observed increase in the Al-O(H1)-Al angle at low temperature.

The oceanic component of its global budget is currently unquantifiable because of a lack of surface seawater measurements. Given values for internal removal and for solubility, marine mixed layer modelling can set bounds for air-sea transfer. Rate constants have been measured in seawater, 0.5m NaCl and distilled water for attack on methyl bromide by the chief oceanic nucleophiles chloride ion and H sub(2)O, over much of the oceanographic temperature range (0 degree C to 22 degree C). Henry's Law constants have been determined for the same conditions. All results are consistent with classical aqueous phase research adjusted for ionic strength effects. The lifetime of methyl bromide with respect to chemical decay in seawater is three weeks at average surface temperatures, and a factor of ten larger and smaller at the extremes. Its dimensionless solubility ranges from 0.1 to 0.3. Analogous experiments are reported for the other natural methyl halides, CH sub(3)Cl and CH sub(3)I.

It is suggested that it is more likely that the absence of basalts inside silicic fields is instead due to the transition from transport via magma fracture to that of basaltic fluid flowing through another fluid (the silicic host).

In most Western Interior Basin sites, in Colombia, and in western Europe (weaker), two closely spaced elemental abundance peaks occur in the upper Cenomanian ( approximately 92 m.y.), spanning the ammonite zones of Sciponoceras gracile through Neocardioceras juddii. Elements with anomalously high concentrations include Sc, Ti, V, Cr, Mn, Co, Ni, Ir, Pt and Au. The lower peak coincides with the disappearance (extinction) of the foraminifer Rotalipora cushmani. In North American sections R. greenhornensis also disappears at or just below this horizon, but in Europe it disappears considerably earlier than R. cushmani. A series of molluscan extinction and speciation or migration events also begins near the stratigraphic level of the lower elemental abundance peak. The well-documented positive delta (super 13) C excursion begins just before the extinctions and the elemental anomalies, and continues into the lower Turonian, well above the upper anomaly. This carbon isotope excursion has been observed in East European sections where we find little or no evidence of the elemental anomalies, suggesting that the two phenomena may not be tightly coupled. Elemental abundance ratios in the anomalies closely resemble those of Mid-Atlantic Ridge basalt or Hawaiian lava (tholeiitic), but not those of C1 chondrite, black shale, average crustal rocks, or lamproite and kimberlite of roughly similar age in southeastern Kansas. The excess Ir and other siderophiles hint at possible large-body impact(s) for the source. However, we have not located microspherules (other than biogenic calcispheres) or shocked mineral grains in any of our samples. Furthermore, Sc, Ti, V and Mn are not enriched in differentiated Solar-System bodies. Although the weak geochemical signal from comet impact(s) could be masked by the strong terrestrial-like overprint, these anomalies more likely resulted either from intense seafloor spreading activity or merely from increased circulation of deep, metal-rich water associated with the large late Cenomanian through early Turonian eustatic rise and deep-water opening of the South Atlantic. The flooding of continental seaways and margins also could have contributed to the anomalies by preventing much continental detritus from diluting the normal background marine geochemical component.

Further, the cosmogenic (super 21) Ne/ (super 22) Ne ratios are distinct for different proton energy ranges and increase systematically with increasing shielding. This variation in cosmogenic (super 21) Ne/ (super 22) Ne represents a progression from a mixed component produced from solar flare protons (SCR) and galactic cosmic rays (GCR) to a pure GCR component. Using the 2 m.y. exposure age for 61016, the calculated production rates for SCR (super 21) Ne and (super 38) Ar from solar energetic protons in near-surface samples agree within 5% and 25%, respectively, with theoretical estimates. Calculated GCR production rates for (super 21) Ne and (super 38) Ar in the deepest (26 mm) samples agree within 25% and 10%, respectively, with theoretical estimates. Combined SCR and GCR concentration profiles for (super 21) Ne, (super 22) Ne, and (super 38) Ar match theoretical calculations based on an omnidirectional flux above 10 MeV of 100 protons cm (super -2) s (super -1) with an exponential rigidity between 70 and 85 MV and a surface erosion rate of 1 mm m.y. (super -1) . Selectively etched, near-surface samples suggest a long-term average (super 4) He/ (super 3) He ratio of approximately 770 for implanted solar flare nuclei with E > approximately 4 MeV amu (super -1) , and a (super 4) He/ (super 3) He ratio of approximately 3450 for solar flare nuclei with E > approximately 1 MeV amu (super -1) . Averaged over long term, the solar flare (super 4) He/ (super 3) He ratio appears energy dependent.

The epithermal mineralization and thermal springs typically occur along high-angle faults within the broad San Andreas transform fault system that forms the western boundary of the North American plate in this area. The young volcanic rocks overlie Mesozoic marine rocks of the Great Valley sequence which have been thrust above the coeval Franciscan Complex and penecontemporaneously dropped back down along low-angle detachment faults.Many of the waters of the region are nonmeteoric as defined by their isotopic signature. One type of isotopically shifted water emerges from or near Great Valley sequence rocks and is the most chloride rich. It is interpreted to be evolved connate in origin. A second type, evolved meteoric water, has moderate chloride contents, high boron contents, and high B/Cl ratios and is found locally in Franciscan rocks, notably at the Sulphur Bank mercury mine, where it probably results from near-closed-system, repeated boiling of meteoric water in host rocks that also contribute organic components to the water. At the Sulphur Bank mine fracturing of otherwise impermeable Franciscan rocks by faulting has created a localized zone of permeability in which thermal water boils repeatedly with limited venting to the surface. Boron-rich fluids were apparently present at depth in The Geysers geothermal field when intrusion of silicic magma occurred, because the concealed intrusion of felsite is surrounded by a halo of tourmaline-bearing hornfels. The volume of this poorly dated early to middle Quaternary intrusive body probably exceeds the 100 km (super 3) of erupted Clear Lake Volcanics. Similar intrusions may have occurred in the eastern part of the area at Wilbur Springs and the McLaughlin mine, where gold deposition and evidence of hydrothermal phenomena suggest more magmatic activity than is indicated by the small exposed bodies of early Quaternary basaltic lava. The Clear Lake Volcanics are the present locus of volcanism in the northern Coast Ranges and progressively older volcanic centers occur to the south. Geophysical data suggest that a large silicic magma body may be centered north of The Geysers steam field, providing the heat for the geothermal field.Geothermal power production has peaked at The Geysers and pressure declines indicate significant depletion of the fluid resource. The vapor-dominated field evolved from a preexisting hydrothermal system within fractured, otherwise impermeable Franciscan metamorphic rocks. A deep water table of saline fluid has been postulated to be present under the steam field, but no chloride-rich water has been found at drillable depth. We propose that recently discovered, isotopically shifted steam in the northwest Geysers area indicates the presence not of deep connate water but xather of boiled-down, boron-rich Franciscan evolved meteoric water. This water is likely to be present in limited quantities and will not provide a significant hot water resource for geothermal power production at The Geysers field or from the main Clear Lake volcanic field.

The objective was to establish the vertical distribution of mantle extraction ages for an undisturbed Precambrian crustal province characterized by normal thickness and low cratonic heat flow, and to thereby evaluate the importance of magmatic or tectonic underplating in crustal growth. Mid-Proterozoic-age (1.7-2.0 Ga) material is found at all levels of the crust. Although mafic granulites and amphibolites have major and trace element compositions compatible with an origin as magmatically underplated material, Nd model ages do not indicate that there has been significant mantle contribution to the lower crust by igneous processes (such as magmatic underplating) since the main crust-forming event ca. 1.85 Ga ago. The meta-igneous lower crustal xenoliths have relatively radiogenic Nd isotopic compositions and unradiogenic Sr compositions. There is little variability in Nd model ages in spite of large variability in Sm/Nd. High and variable Sm/Nd ratios were therefore established early in the history of the protolith, during igneous or metamorphic processes coincident with or shortly after extraction from the mantle. Metapelitic xenoliths, tectonically emplaced into the lower crust, have the same Proterozoic model ages as meta-igneous parts of the lower crust. These paragneisses are probably arc-associated sediments that were underthrust during terrane accretion in the Proterozoic. The isotopic data indicate that eclogite xenoliths are likely to represent Proterozoic lithosphere rather than subducted Mesozoic MORB, as previously proposed. A number of the eclogite xenoliths have experienced a metasomatic event which introduced LREE, SiO (sub 2) and Na (sub 2) O and shifted the Nd and Sr isotopic compositions. The least-altered eclogite xenoliths have major and trace element and radiogenic Nd isotopic compositions similar to those of other Proterozoic mafic, lower crustal xenoliths. A more plausible protolith for the eclogites is Proterozoic lithosphere that was metamorphosed to eclogite facies conditions either during Precambrian continental assembly or in more recent times.

Using realistic permeability fields for young oceanic crust, we have performed numerical simulations of finite amplitude, steady and unsteady convective fluid flow in layered and/or anisotropic porous media heated from below to investigate particular patterns of fluid flow and temperature in mid-ocean ridge hydrothermal systems. On the flanks of mid-ocean ridges, permeability measurements in deep-sea boreholes suggest that only the top few hundred meters of oceanic crust is permeable. Given this permeability structure (and assuming some minimum permeability and layer thickness), our models predict that convection occurs in the form of numerous cells with aspect ratios of order unity within this permeable layer. Such convection results in fluid flux and diagenetic reactions within the permeable layer with a negligible effect on heat flow at the seafloor, in agreement with field observations. Estimates of oceanic crust permeability based on hydrothermal veins in ophiolites and measurements in deep-sea boreholes suggest that pillow basalts/lava flows are much more permeable than underlying sheeted dikes. This is particularly true at the ridge crest where voids have not yet collapsed and filled. Given this permeability structure, our study suggest that a small percentage of the fluid entering the ridge crest circulates through the sheeted dikes before exiting the system at high temperatures in very focused discharge zones. In our models, these discharge zones narrow considerably at the interface between the sheeted dikes and the pillow basalts/lava flows. Much of the fluid entering the system, however, never circulates below the pillow basalts/lava flows and exits the seafloor at low temperatures. In general, discharge zones are more focused than recharge zones. These results are consistent with observations of narrow and focused discharge zones in ophiolites and localized high-temperature venting amid widespread low-temperature flow on the ridge crest. The spacing of upflow zones at the surface is strongly controlled by convective flow in the bottom permeable layer. In our models, near-field effects dominate over far-field effects in systems with lateral variations in permeability, and no large-scale flow develops between widely spaced areas of contrasting permeability. The time to steady-state and evolution of convective flow in porous media vary considerably with initial conditions. Our simulations suggest that the time to steady-state is relatively long and that it is possible that hydrothermal convection at the ridge axis never reaches a steady-state flow pattern, in the sense that the variations in the system boundary conditions such as basal heat flux may occur on a time scale less than the response time of the hydrothermal system. It is possible, however, that these systems may be quasi-steady for significant periods of time.

Bulk-rock samples and clay-mineral separates from three drill holes at Yucca Mountain (USW G-1, USW G-2, and USW GU-3/G-3) were studied using X-ray powder diffraction, and supporting temperature information was obtained using fluid inclusion data from calcite. Twelve K/Ar dates were obtained on illite/smectite (I/S) separated from the tuffs from the two northernmost drill holes, USW G-1 and G-2. The predominant clay minerals in the Yucca Mountain tuffs are interstratified I/S, with minor amounts of chlorite and interstratified chlorite/smectite. The I/S reactions observed as a function of depth are similar to those observed for pelitic rocks; I/S transforms from R = 0 interstratifications through R = 1 and R > or = 3 interstratifications to illite in USW G-2 and to R > or = 3 I/S in USW G-1. The R = 0 I/S clays in USW GU-3/G-3 have not significantly transformed. K/Ar dates for the I/S samples average 10.4 my. These data suggest that the rocks at depth in the northern portion of Yucca Mountain were altered 10.0-11 my ago, soon after creation of the Timber Mountain caldera to the north. Both I/S geothermometry and fluid inclusion data suggest that the rocks at depth in USW G-2 were subjected to postdepositional temperatures of at least 275 degrees C those in USW G-1 reached 200 degrees C, and rocks from USW GU-3/G-3 probably did not exceed 100 degrees C These data suggest that no significant hydrotbermal alteration has occurred since Timber Mountain time, approximately 10.7 my ago. Estimates of the temperature of formation of illite/smectites yield probable stability limits for several minerals at Yucca Mountain. Clinoptilolite apparently became unstable at about 100 degrees C mordenite was not a major phase above 130 degrees C and analcime transformed to albite above 175 degrees -200 degrees C. It appears that cristobalite transformed to quartz at 90 degrees -100 degrees C in USW G-2 but must have reacted at considerably lower temperatures (and for longer times) in USW GU-3/G-3. The reactions with increasing depth appear coupled, and clinoptilolite and cristobalite disappear approximately simultaneously, supporting aqueous silica activity as a controlling variable in the clinoptilolite-to-analcime reaction. The reaction of clinoptilolite to analcime also coincides with the appearance of calcite, chlorite, and interstratified chlorite/smectite. Although the hydrothermal fluids may have been a source for some cations, breakdown of clinoptilolite (and mordenite) probably provided the source of some of the Ca for calcite, Mg for chlorite, K for the I/S found deeper in the section, and Na for analcime and albite. Using the rocks in USW G-1, G-2, and GU/G-3 as natural analogs to repository-induced thermal alteration suggests that the bulk of the clinoptilolite- and mordenite-bearing rocks in Yucca Mountain will not react to less sorptive phases such as analcime over the required lifetime of the potential repository. The zeolites in zeolite interval I, directly underlying the proposed repository horizon, may transform at the predicted repository temperatures. However, the reaction of clinoptilolite to analcime in interval I may require the transformation of all of the abundant opal-CT and glass to quartz, an unlikely scenario considering the unsaturated nature of these rocks and the predicted temperatures of < 100 degrees C.

We calculate the velocity and temperature distribution for axisymmetric convection above a heated disk in an incompressible fluid cylinder, 2400 km in height and 1200 km in diameter, initially at a uniform temperature T (sub infinity) . The lower boundary, representing the plume source region near the core-mantle boundary, is stress-free and maintained at temperature T (sub c) > T (sub infinity) . The upper boundary is permeable, allowing the plume to escape the cylinder. We determine the sensitivity of plume structure to viscosity variations eta (sub infinity) /eta (sub c) ranging from 10 (super 2) to more than 10 (super 4) and temperature differences Delta T = T (sub c) - T (sub infinity) . in the range 400-850 K. Starting plumes consist of a large leading diapir and a trailing conduit connected to the thermal boundary layer above the heated surface. The leading diapir expands during ascent, to about 400 km diameter at 2200 km height. In steady state, the plume consists of a narrow, high-velocity conduit imbedded within a broader thermal halo. The width of both these structures is proportional to height above the heated boundary and inversely proportional to Delta T and the viscosity ratio. Heat transport in the plume is nearly independent of viscosity variations. A simplified boundary layer model yields a heat transfer law, Nu nearly equal Ra (super 1/3) where Nu is the plume Nusselt number and Ra is the Rayleigh number based on, Delta T, eta (sub infinity) and the radius of the heated circular region feeding the plume. Calculated steady state plume heat transports fit this law to within a few percent. We present several calculations of plumes with heat transport in the range 100-400 GW, similar to the advective heat transport by the Hawaiian hotspot. At the top of the lower mantle, plumes with large viscosity variations have high-velocity conduits 50-60 km in diameter and 125-km-diameter thermal halos, a centerline temperature anomaly of about 500 K and a centerline velocity of about 75 cm yr (super -1) . Plumes with weak viscosity variations are approximately twice as broad and have centerline temperature anomalies less than 160 K at the same height and much smaller velocity. Large viscosity variations and a minimum heat transport are both Copyright 1993 by the American Geophysical Union.

IV. Cell inactivation by alpha particles of energies 0.4-3.5 MeV. AN - 75632622; 8451379 AB - In this report the effectiveness of low-energy alpha particles in the range 0.4 to 3.5 MeV for cell killing is investigated. Four cell lines of different nuclear dimensions (AG1522, C3H 10T1/2, CHO-10B, and HS-23) are studied. Monte Carlo simulations are carried out to interpret the experimental results. They are presented as a function of dose to the nucleus, the total track length of alpha particles in the nucleus, and other parameters. It is found that the effectiveness of alpha particles for cell killing decreases with decreasing alpha-particle energy. The maximum RBE value is found to extend to LET values as high as 180 keV/microns. Although the LET might be the same, the effectiveness of alpha particles for cell killing is higher in the ascending part of the Bragg curve compared to descending part of the Bragg curve. The terminal tracks of alpha particles are observed to be less effective for cell killing.

Remote-sensing images that include visual representation of depth are an even more powerful tool for geologic interpretation of landscapes, but their use has been largely restricted to the exploration of planets other than Earth. By combining Landsat images with digitized topography, we have generated regional oblique views that display compelling evidence for a previously undocumented late-Cenozoic caldera within the active volcanic zone of southwestern Guatemala. This "new" caldera, herein called Xela, is a depression about 30 km wide and 400-600 m deep, which includes the Quezaltenango Basin. The caldera depression is breached only by a single river canyon. The caldera outline is broadly circular, but a locally scalloped form suggests the occurrence of multiple caldera-collapse events, or local slumping of steep caldera walls, or both. Within its northern part, Xela caldera contains a toreva block, about 500 m high and 2 km long, that may be incompletely foundered pre-caldera bedrock. Xela contains several post-caldera volcanoes, some of which are active. A Bouguer gravity low, tens of milligals in amplitude, is approximately co-located with the proposed caldera. The oblique images also display an extensive plateau that dips about 2 degrees away from the north margin of Xela caldera. We interpret this landform to be underlain by pyroclastic outflow from Xela and nearby Atitlan calderas. Field mapping by others has documented a voluminous rhyolitic pumiceous fallout deposit immediately east of Xela caldera. We speculate that Xela caldera was the source of this deposit. If so, the age of at least part of the caldera is between about 84 ka and 126 ka, the ages of deposits that stratigraphically bracket this fallout. Most of the floor of Xela caldera is covered with Los Chocoyos pyroclastics, 84-ka deposits erupted from Atitlan caldera. Oblique images produced from digital data are unique tools that can greatly facilitate initial geologic interpretation of morphologically young volcanic (and other) terrains where field access is limited, especially because conventional visual representations commonly lack depth perspective and may cover only part of the region of interest.

(super 231) Pa/ (super 235) U activity ratios for axial basalts are large and relatively uniform within ridge segments. The systematically large (super 231) Pa/ (super 235) U, (super 230) Th/ (super 238) U, and (super 226) Ra/ (super 230) Th activity ratios in MORB are inconsistent with simple equilibrium melting models and crustal contamination or seawater alteration processes. More complicated melting processes involving disequilibrium or heterogeneous melting of mantle sources and disequilibrium transport of melts to the crust could produce the large U-series disequilibria in MORB. (super 231) Pa and (super 230) Th model ages were determined by estimating initial (super 231) Pa/ (super 235) U and (super 230) Th/ (super 232) Th ratios from axial samples and by assuming constancy of these ratios over time. All (super 231) Pa and (super 230) Th ages agree to + or -0-7 ka for samples with ages of 0-130 ka. These concordant ages validate the model assumptions of the two dating methods and 0uggest that mantle sources and melt generation processes have been uniform for these areas during the past 130 ka.

The frequency domain travel time (FDTT) method produces the continuous-wave (cw) response of a propagating wave by stepwise sweeping frequency of a driving source and detecting amplitude and phase of the received signal in reference to the source. Each separate travel path yields a characteristic repetition cycle in frequency space as its wave vector-distance product is stepped; an inverse fast Fourier transform (IFFT) reveals the corresponding travel time at the group velocity. Because arrival times of direct and reflected elastic waves appear as spikes along the time axis, travel times can be obtained precisely, and different arrivals can be clearly separated. Q can be determined from the amplitude vs. frequency response of each peak as obtained from a moving window IFFT of the frequency-domain signal. In this sample at ambient conditions compressional velocity V (sub P) is 2380 m/s and Q (sub P) is 55. Copyright 1993 by the American Geophysical Union.

The model shows an inherently three-dimensional flow pattern with cyclindrical plumes and linear sheets which behave differently in their ability to penetrate the phase change. Accumulation of downwelling cold material above 670 km depth results in avalanches of upper-mantle into the lower mantle, generating long-wavelength lateral homogeneity. This resolves the contradiction between seismic tomographic data and inferences from mantle convection simulations.

The fields are Fourier transformed in the invariant conductivity direction and then expressed in a variational form. At each of a set of discrete spatial wavenumbers a finite-element method is used to obtain a solution for the secondary electromagnetic fields. The finite element uses exponential elements to efficiently model the fields in the far-field. In combination with an iterative solution for the along-strike electromagnetic fields, this produces a considerable reduction in computation costs. The numerical solutions for a horizontal electric dipole are computed and shown to agree with closed form expressions and to converge with respect to the parameterization. Finally some simple examples of the electromagnetic fields produced by horizontal electric dipole sources at both the seafloor and air-earth interface are presented to illustrate the usefulness of the code.

Various techniques were considered and a seismic reflection survey was selected. This survey was then fitted to the conditions at the test site so as to give optimum results. The data was then reduced via DOS computer and analyzed for content. The planned survey using a 50 ft offset did not show any useful information, however, a second survey with a variable longer offset was also conducted which was capable of determining the depth to the top and the bottom of the chimney with reasonable accuracy.

Here, we review current knowledge of chemical compositions of lunar materials in the context of known or suspected lunar geochemical processes. We speculate on how various elements might have been concentrated into potential ore deposits.

Little or no extension accompanied the extrusion of a 0.5-1 km thick sequence of transitional tholeiitic flood basalts between 45 and 35 m.y. Felsic eruption(s) at approx 37 m.y. covered much of the S Ethiopian plateau region with a felsic tuff unit; a second, less widespread, episode of alkali basalt and trachyte volcanism occurred between 18 and 11 m.y., and Recent alkali basalt volcanism occurs in the Chamo basin. The small amounts of lithospheric extension and the large volumes of magma estimated in this study suggest a very hot plume and/or efficient thinning of the mantle lithosphere from below, by mantle plume processes during the two discrete episodes of flood-basalt volcanism.

Each pluton cooled through approx 320 degrees C within 4-5 m.y. at the existing exposure level, but insignificant cooling has taken place since the late Triassic at present depths of 2-2.5 km. Greisen-bordered wolframite vein systems and lodes formed simultaneously with the cooling to approx 320 degrees C of the host intrusive rocks, lending support to an origin related to retrograde boiling of apical magmas. Major Sn-Cu lode development in the Carn Brea district was initiated 1-3 m.y. after emplacement of the local W-rich veins, and was broadly coeval with cooling of the Carnmenellis pluton--through T (sub c) muscovite at 1-1.5 km below the greatest known depths of economic cassiterite deposition in the mineralized shear-zones. Both clans of lithophile-metal deposits formed diachronously across the province; thus all cassiterite deposition in the lodes of the South Crofty mine took place prior to intrusion of the St Austell and Land's End plutons. Tonalitic-to-granodioritic enclaves in coarse-grained biotite monzogranite bodies are interpreted as hybridized 'pillows' of mafic melts, implying that crustal anatexis was directly stimulated by episodic incursion of magma(s) from the subjacent mantle.

From size analyses of the Misers Gold preshot test bed alluvium, ejecta, and sweep-up materials collected out to 35 crater radii (1227 m), we find that approximately 5.9 X 10 (super 6) kg ( approximately 11% of the total crater ejecta mass) was depleted from the crater ejecta deposits and likely represents the portion of the cratered mass initially lofted into atmospheric suspension. The dominant size range of this lofted dust was 88 to 2000 mu m with a mean diameter by mass of 384 mu m,. In addition to the dust lofted in the explosion column, dust in the size range of 100-800 mu m was swept up from the ground by the explosive air blast and base surge dominantly between ranges of 10 and 18 crater radii (360 and 650 m from ground zero). This sweep-up dust was convectively drawn into the column and contributed up to 2% of the total mass of lofted. Based on the measured abundance of coarse (>250 mu m diameter) dust particles in the estimated lofted dust, it is likely that about 70% of this lofted mass fell out within about 1 hour, such that the remaining dust cloud mass was approximately 1.8 X 10 (super 6) kg, which is equivalent to a dust lofted per unit blast yield of 0.5 kT/kT or about 4% of the crater ejecta mass. This study supports the hypothesis that if initial distributions can be constrained, the volume of dust lofted into atmospheric suspension from large surface explosions can be estimated from analysis of particle-size distributions of ejecta deposited near the explosion. This result may have particular applications to study of the atmospheric effects of historic and prehistoric volcanic eruptions.

The samples represent the extremes of trace element fractionation for this cinder cone. Ages range from 80 000 yr to 17 000 yr which are consistent with estimates from the geomorphology, soil profile development and K/Ar determinations. Comparison of the relative chronology with compositional trends suggests that eruptive centres in the volcanic field are fed by individual magma chambers.

(super 14) C ages average 1860 yr B.P., which is in agreement with the potsherds found in palaeosols under- and overlying the deposit. The eruption sequence consists of seven members, most of which are pumice fall deposits, though one is an ash and pumice fallout, and another is a surge bed. The tephra have a trachytic-phonolitic composition. All the chemical characteristics, including major, trace element and Sr isotope compositions, are homogeneous throughout the sequence. The vesicularity of pumice clasts does not show any systematic change; the erupted magma had the same amount of volatiles, the same flux and the same vesicle growth behaviour throughout. Grain-size analyses of 90 tephra samples, representative of all the members at variable distance from the supposed vent, have been processed using the sequential fragmentation/transport theory in order to define the effects of eruptive fragmentation and subsequent transport on the particle size distribution. Four significant subpopulations have been identified and related to transport mechanisms.

We observe broad Moessbauer lines, suggesting a distribution of electric-field gradients caused by disorder associated with the Fe ions. Also, the perovskite exhibits magnetic ordering at temperatures < 5 K, implying that there is a magnetic contribution to the absolute ("third-law") entropy of this phase.

AN - 73304681; 1331128 AB - Treatment of quiescent density-arrested A31T6 proadipocytes with medium supplemented with either 12-O-tetradecanoylphorbol-13-acetate (TPA), insulin, or cholera toxin alone did not stimulate G0/G1 traverse and initiation of DNA synthesis. Combinations of either TPA and cholera toxin or insulin and cholera toxin caused a small stimulation of proliferation. Addition of medium supplemented with TPA and insulin caused a marked stimulation of cell cycle traverse which was significantly potentiated by the coaddition of cholera toxin. The actions of cholera toxin were mimicked by forskolin. Expression of c-fos was regulated in a manner that reflected the results of the mitogenic experiments. TPA caused a marked induction of expression, while only a small increase in transcript levels was seen after treatment with cholera toxin. Addition of a combination of cholera toxin and TPA caused a synergistic induction of c-fos expression. The model system described in this paper allows a detailed analysis of the regulation, by independent second messenger systems, of the transcription of a gene in a mitogenically relevant manner.

Those from the Waits River formation show trace-element zoning apparently related to mineralogical changes (reaction histories), with complex inclusion suites and zoning patterns of Y, Zr and the REE. Those from the Goshen formation, however, show variability in trace-elements reflecting changing intensive variables during garnet growth; they show an interval during which Ca, Na and Ti drop in abundance, suggesting late-stage growth along a decompression and heating path. The REE, Y and Mn appear to have the opposite trend from Na, Ca and Ti in the late-stage P-T fluid path of some samples. Proton-probe microanalysis of minerals in these calc-pelites demonstrates strong affinities of specific trace elements for certain minerals: Y in garnet, Ga and Rb in biotite, Zn and Ga in staurolite, Rb and Sr in muscovite, Sr and Pb in plagioclase and Nb in ilmenite.

The parabolic features are, with seven exceptions, oriented E-W with the apex to the east and the impact crater located just west of the apex. They were first identified in the surface emissivity data derived from Magellan radiometry measurements, but the great majority are only clearly visible in the SAR imagery. The overall sizes of both the parabolic and circular features range from several hundred to about two thousand kilometers and are loosely correlated with the diameters of the "parent" craters. The floors of almost all these craters have high specific radar backscatter cross sections (i.e., they are bright in the SAR imagery) relative to their surroundings and tend to have low emissivities. Approximately one-third of the impact craters with diameters > or =15 km appear to have bright floors and about half of these have an associated parabolic feature which can be observed in the SAR or emissivity data. No features have been found which overlie the parabolic features, indicating that they are among the youngest features on the surface of the planet. This suggests that radar-bright floors characterize the freshest impact craters and that modification processes subsequently darken their radar signature. A model for the formation of the parabolic features is developed based on the injection of small particles into the upper atmosphere at the time of impact and their transport to the west by the E-W zonal winds. Fitting of a small perturbation scattering model to the measured average scattering law for the parabolic features placed an upper limit of about 0.6 cm on the wavelength scale (12.6 cm) surface roughness and, hence, of 1 to 2 cm on the largest particle sizes of interest. Fallout times from 50 km in the Venus atmosphere for particles of this size are about 2 hours, allowing westerly drifts of several hundred kilometers for zonal winds of 50 to 100 m s (super -1) . Measurements of the change in backscatter cross section of features overlaid by these extended ejecta deposits, are consistent with deposit depths of a few centimeters to 1 or 2m.

AN - 85153307; pmid-1401524 AB - Effects of a possible inner-ear compressibility on middle-ear transfer functions are explored and a small upper bound on the magnitude of that compressibility established. Consequently. the traditional two-port representation of middle-ear mechanics remains valid to within a few percent. If the compressibility of the cochlea is small but finite, a simple phenomenological model of that compressibility correctly predicts hearing thresholds in the "middleless" ear at low frequencies. Experiments to establish the value of cochlear compressibility and to explore further its possible contributions to residual hearing in patients with missing or disarticulated middle-ear ossicles are suggested.

Am. 92, 1356-1370 (1992)] characterizes both forward and reverse transmission through the middle ear. This paper illustrates its use in the analysis of noninvasive measurements of middle-ear and cochlear mechanics. A cochlear scattering framework is developed for the analysis of combination-tone and other experiments in which acoustic distortion products are used to drive the middle ear "in reverse." The framework is illustrated with a simple psychophysical Gedankenexperiment analogous to the neurophysiological experiments of P. F. Fahey and J. B. Allen [J. Acoust. Soc. Am. 77, 599-612 (1985)].

AN - 85150218; pmid-1401522 AB - To provide a common ground for the comparison between theory and experiment, this paper presents a framework for the phenomenological description of middle-ear mechanics. The framework defines those measurements sufficient to characterize the transduction properties of the middle ear and its components. Phenomenological equations are represented in the form of an equivalent electrical circuit that can be used to deduce testable relations among measurable quantities. Two applications are then discussed. First, the classical concept of the middle-ear transformer ratio is generalized to include any effects of eardrum flexion or nonrotational ossicular motion. Middle-ear models predict that the resulting transformer ratios vary considerably with frequency. Second, the conditions under which the topology of existing circuit analogs satisfactorily approximates middle-ear mechanics are given. Most middle-ear models cannot be used to correctly predict the absolute pressures in the cochlea.

AN - 85155153; pmid-1506525 AB - This paper describes a method for inferring articulatory parameters from acoustics with a neural network trained on paired acoustic and articulatory data. An x-ray microbeam recorded the vertical movements of the lower lip, tongue tip, and tongue dorsum of three speakers saying the English stop consonants in repeated Ce syllables. A neural network was then trained to map from simultaneously recorded acoustic data to the articulatory data. To evaluate learning, acoustics from the training set were passed through the neural network. To evaluate generalization, acoustics from speakers or consonants excluded from the training set were passed through the network. The articulatory trajectories thus inferred were a good fit to the actual movements in both the learning and generalization conditions, as judged by root-mean-square error and correlation. Inferred trajectories were also matched to templates of lower lip, tongue tip, and tongue dorsum release gestures extracted from the original data. This technique correctly recognized from 94.4% to 98.9% of all gestures in the learning and cross-speaker generalization conditions, and 75% of gestures underlying consonants excluded from the training set. In addition, greater regularity was observed for movements of articulators that were critical in the formation of each consonant.

AN - 73304335; 1430781 AB - Previous studies with cultured normal human fibroblasts indicated that treatment of cells with zinc before exposure to an alkylating agent enhanced cell survival by seven- to ninefold. To establish whether a similar zinc-induced protective response could be elicited in vivo, we conducted a preliminary experiment in which Balb/cJ female mice were treated with zinc (2 mg kg-1 body weight) or saline by intraperitoneal (i.p.) injection at 48, 36, 24 and 12 h before i.p. administration of the alkylating agent nitrogen mustard (4 mg kg-1 body weight). Of the animals that received saline before nitrogen mustard, 57% died as compared with only 20% in the group treated with zinc before administration of the alkylating agent. As was observed in the studies of cells in culture, the results described in this report may suggest the existence in Balb/cJ female mice of a zinc-mediated protective response against nitrogen mustard toxicity.

AN - 73296994; 1430782 AB - The use of alkylating agents in treating cancer is limited by their toxicity to both normal and tumor tissue. Early in vitro studies indicated that zinc might be effective in mitigating this toxicity to normal tissue. The present studies were done to determine the capability of zinc to induce in vivo a protective response to an alkylating agent without also contributing to mortality. Tumor-free and L1210 leukemia-bearing female B6D2F1 mice were treated with zinc before administration of the alkylating agent nitrogen mustard. Protocols for administration route and frequency as well as the chemical formulation of the zinc were varied. The effect of a phytate-free diet was studied. Two parameters were used to determine the effectiveness of zinc in protecting animals from the toxicity of nitrogen mustard: the number of tumor-free mice that survived and an increase in the median life span of the tumor-bearing mice. The zinc-induction protocols used in these studies provided a limited degree of protection against nitrogen mustard toxicity in tumor-free female mice, but in tumor-bearing animals the protective response elicited with the protocols examined did not provide an appreciable therapeutic benefit.

AN - 73179194; 1522011 AB - The whole body of an individual injected with Thorotrast 36 y prior to her death was analyzed for 232Th, 228Ra, 228Th, and 230Th. Measurement of these isotopes in all tissues of the body will provide data necessary to caculate the radiation dose to individual tissues and to evaluate the risk potential associated with deposition of thorium and progeny in humans. The tissues were ashed, dissolved in acid, and the thorium isolated by ion exchange and electrodeposition. The 228Ra was determined by measuring the 0.991-MeV gamma rays associated with decay of the 228Ac daughter. It was estimated that almost all of the 232Th from the original injection was retained in the body, mostly in the tissues of the reticuloendothelial system. A total of 28 kBq (0.76 microCi) of 232Th was measured in the soft tissues and bones. The body also contained 13 kBq 228Ra, 12 kBq 228Th, and 3.9 kBq 230Th. A Thorotrastoma contained about 3.5% of the total activity. Excluding the Thorotrastoma, approximately 45% of all the activity (232Th, 228Ra, 228Th, and 230Th) was retained in the liver, 13% in the spleen, 2% in muscle, 1% in skin, slightly less than 1% in the respiratory tract, 4% in all other soft tissues, and 33% in the skeleton (bone and bone marrow). Sixty to 80% of the thorium activity in bones containing red marrow was located in the marrow. Bones containing yellow marrow had less than 40% of the thorium activity in the marrow. Highest concentrations were found in the hepatic and other abdominal lymph nodes, spleen, hilar lymph nodes, liver, trachea, and bone. Approximately 60% of the 228Ra formed from the decay of the 232Th had been excreted from the body. The 228Ra and 228Th were in approximate equilibrium throughout the body.

AN - 73148272; 1505003 AB - Small-angle X-ray and neutron scattering experiments have given important information on the solution structures of calmodulin and its complexes with synthetic peptides used to model target enzyme interactions. In combination with crystallographic data, site directed mutagenesis and various spectroscopic studies, these experiments have contributed to our understanding of the solution structure of calmodulin in different functional states. We have gained important insights into the conformational flexibility in calmodulin that appears to be crucial to its regulatory functions. Specifically, flexibility in the interconnecting helix region of calmodulin has been shown to play a critical role in facilitating calmodulin's binding to a wide variety of target enzymes whose activities are thus regulated. This review will focus mainly on the contributions small-angle scattering has made to our understanding of the solution structure of calmodulin in the context of other studies, with particular regard to circular dichroism and Fourier transform infrared studies that complement the small-angle scattering data.

The refinement in space group Cl-(combining macron) yielded high precision lattice parameters (a = 5.36982(5)Aa, b = 9.3031(9)Aa, c = 14.2610(6)Aa, alpha = 90.315(5) degrees , beta = 97.234(7) degrees , gamma = 90.022(9) degrees ) and atomic coordinates very similar to previous studies. However, the presence of semi-random stacking in this specimen created a situation in which not all atoms could be precisely located: the positions of the octahedral cations and anions which repeat at intervals of + or -b/3 could be uniquely determined in three dimensions whereas only the z parameter of the other atoms could be refined. The reasonable appearance of the final model, despite the fact that many of the atom positions could be located in only one dimension, may have resulted because all of the atoms in this structure except O(5) repeat at intervals which are very nearly + or -b/3.

Solar wind electron analyzers previously flown to distances >1 AU did not resolve the halo electron distribution so that the 3-D suprathermal solar wind electron observations from Ulysses represent a unique data set. As the core population cools with increasing heliocentric distance, no gap is formed between the core and halo populations. Rather, the halo electrons extend to increasingly lower energies. As predicted previously on theoretical grounds, the ratio of the core electron temperature to the low energy cutoff of the halo population appears to be roughly constant with a value of 7.5. The total integrated heat flux drops rapidly with increasing heliocentric distance; we find a best fit power law of R super(-2.36). In addition, we find that the ratio of the halo to core densities is roughly constant over heliocentric distance with the halo representing 4% of the total electron distribution. These results suggest that the halo population may not consist of truly non-interactive test particles over the heliocentric range of 1-4 AU.

AN - 85148927; pmid-1597611 AB - Theory and measurements of the use of two adjacent pressure sensors to measure acoustic power flow of a simple harmonic sound wave in a duct are presented. This theory differs from the usual intensity-times-area formulation of this problem by including the phase shift between pressure gradient and velocity, which is caused by viscous drag on the gas at the duct wall. For high standing-wave ratios, the power obtained by this method differs significantly from the product of mid-duct intensity and duct area.

AN - 75530975; 11537863 AB - Observation of the size distribution of transient cavities in computer simulations of water, n-hexane, and n-dodecane under benchtop conditions shows that the sizes of cavities are more sharply defined in liquid water but the most-probable-size cavities are about the same size in each of these liquids. The calculated solvent atomic density in contact with these cavities shows that water applies more force per unit area of cavity surface than do the hydrocarbon liquids. This contact density, or "squeezing" force, reaches a maximum near cavity diameters of 2.4 angstroms. The results for liquid water are compared to the predictions of simple theories and, in addition, to results for a reference simple liquid. The numerical data for water at a range of temperatures are analyzed to extract a surface free energy contribution to the work of formation of atomic-size cavities. Comparison with the liquid-vapor interfacial tensions of the model liquids studied here indicates that the surface free energies extracted for atomic-size cavities cannot be accurately identified with the macroscopic surface tensions of the systems.

Six illitic clays within Quaternary caldera-fill debris flow, tuffaceous sediment, and ash-flow tuff (48-587 m depth) yield ages of 0.35-1.09 m.y.; illite from Miocene pre-caldera sandstone gives an age of 6.74 m.y.; two dates on illite from sandstones in Permian red beds are 4.33 and 4.07 m.y., respectively; three dates on illites from altered andesite pebbles within the red beds are 0.95-1.06 m.y.; and four illite dates on variably altered Precambrian quartz monzonite are 2.90-276 m.y. Post-Valles age illite is not correlated with alteration style but these ages are obtained from illites in highly fractured, intensely altered, caldera-fill rocks and the Permian volcanic clasts. Plots of (super 40) Ar/ (super 36) Ar vs (super 40) K/ (super 36) Ar and (super 40) Ar* vs (super 40) K for the illites in caldera-fill rocks lie close to a 1 m.y. isochron. Most illite dates older than Valles caldera are difficult to interpret because they correspond with the ages of pre-Valles volcanic and hydrothermal episodes in the Jemez volcanic field (<= 13 m.y.). Older dates may also be caused by mingling of different illites during sample preparation, or by inherited Ar or lost Ar in illites from rocks with potentially complex hydrothermal histories. The evidence indicates that Valles hydrothermal activity is overwhelmingly illite produced by earlier geological events.

Expert judgment has always played a significant role in analysis; however, recent trends are to make it formal, explicit, & documented so it can be identified & reviewed by others. Four categories of expert judgment are proposed, & three case studies are presented that illustrate pitfalls commonly encountered in its use. It is concluded that there will be an expanding policy role for formal expert judgment, & that the openness, transparency, & documentation that it requires have implications for enhanced public involvement in scientific & technical affairs. 1 Table, 4 Figures, 21 References.

Cytotoxic and mutagenic effects of high-LET charged iron particles on human skin fibroblasts. AN - 72793848; 1734447 AB - Cytotoxic and mutagenic effects of high-LET charged iron (56Fe) particles were measured quantitatively using primary cultures of human skin fibroblasts. Argon and lanthanum particles and gamma rays were used in comparative studies. The span of LETs selected was from 150 keV/microns (330 MeV/u) to 920 keV/microns (600 MeV/u). Mutations were scored at the hypoxanthine guanine phosphoribosyl transferase (HPRT) locus using 6-thio-guanine (6-TG) for selection. Exposure to these high-LET charged particles resulted in exponential survival curves. Mutation induction, however, was fitted by the linear model. The relative biological effectiveness (RBE) for cell killing ranged from 3.7 to 1.3, while that for mutation induction ranged from 5.7 to 0.5. Both the RBE for cell killing and the RBE for mutagenesis decreased with increasing LET over the range of 1.50 to 920 keV/microns. The inactivation cross section (sigma i) and the action cross section for mutation induction (sigma m) ranged from 32.9 to 92.0 microns2 and 1.45 to 5.56 X 10(-3) microns2; the maximum values were obtained by 56Fe with an LET of 200 keV/microns.

We discuss a technique for lunar geochemical mapping from landed stationary or moving platforms using Laser-induced Ion Mass Spectrometry (LIMS). In this technique, a focused diode-pumped Nd:YAG laser on an lunar lander or rover vaporizes a thin layer of a soil or rock target located at a range of 5 to >100 m. The vapor is ionized through electron heating by inverse Bremsstrahlung, and the expanding plasma cloud contains information about the target composition. Ions in this plasma are analyzed using specialized time-of-flight ion mass spectrometry, providing detailed composition analysis of the lunar surface. In considering this technique, we discuss the effects on the ion trajectories of ambient electric and magnetic fields and present a high sensitivity, high mass-resolution mass spectrometer that is capable of detecting low atomic mass abundances, trace elements, and isotopic variations.

N1 - Last updated - 2012-06-07 ER - TY - BOOK T1 - Laser-induced breakdown spectroscopy for remote elemental analysis of planetary surfaces AN - 51773142; 2005-001121 AB - One of the most fundamental pieces of information about any planetary body is the elemental and mineralogical composition of its surface materials. We are developing an instrument to obtain such data at ranges of up to several hundreds of meters using the technique of Laser-Induced Breakdown Spectroscopy, or LIBS. We envision our instrument being used from a spacecraft in close rendezvous with small bodies such as comets and asteroids, or deployed on surface-rover vehicles on large bodies such as Mars and Earth's Moon. The elemental analysis is based on atomic emission spectroscopy of a laser-induced plasma or spark. A pulsed, diode-pumped Nd:YAG laser of several hundred mJ optical energy is used to vaporize and electronically excite the constituent elements of a rock surface remotely located from the laser. Light emitted from the excited plasma is collected and introduced to the entrance slit of a small grating spectrometer. The spectrally dispersed spark light is detected with either a linear photo diode array or area CCD array. When the latter detector is used, the optical and spectrometer components of the LIBS instrument can also be used in a passive imaging mode to collect and integrate reflected sunlight from the same rock surface. Absorption spectral analysis of this reflected light gives mineralogical information that, when combined with the elemental analysis from the LIBS mode, provides a complete remote geochemical characterization of the rock surface. We have performed laboratory calibrations in air and in vacuum on standard rock powders to quantify the LIBS analysis. We have performed a preliminary field test using commonly available laboratory components to demonstrate remote LIBS analysis of terrestrial rock surfaces at ranges of over 25 meters. Based on these results, we believe that all major and most minor elements expected on planetary surfaces can be measured with absolute accuracy of 10-15% and much higher relative accuracy. We describe a second field test in which a specially designed compact spectrometer and CCD detector system is combined with a new low-mass, space-rated Nd:YAG laser to constitute a portable LIBS-reflectance spectrometer instrument.

The crustal contribution to silicic igneous rocks is measured in terms of the Nd crustal index (NCI). The relationships between crustal T, basalt supply and NCI are quantified using a model of a magma chamber undergoing continuous recharge, wall-rock assimilation and fractional crystallizations. From the model, a critical value of the ratio of basalt recharge-to-assimilation, (r/a) (sub c) , is deduced, which increases with decreasing crustal T. The r/a value must exceed (r/a) (sub c) to allow the volume of differentiated magma to increase, a prerequisite for developing large volumes of silicic magma. Strongly peraluminous (or S-type) magmas (NCI 0.8-1) form under conditions of high crustal T and low basalt supply. Metaluminous (or I-type) granites form over a wide range of conditions (NCI 0.1-1), generally where basalt supply is substantial. In individual long-lived volcanic centres, the large- volume high-silica ignimbrites are associated with the highest r/a and lowest NCI values, indicating that these magmas are typically differentiates of mantle-derived basaltic parents.
