The orebodies, which are offset by faults of Laramide age, are enriched in an amorphous organic material that was introduced into the host sandstone after deposition. The enrichment by this organic material, in ore, is an important characteristic of the primary uranium deposits in the Grants uranium region. However, the close proximity of the chemically reduced ore zones to oxidized rock is suggestive that the deposits represent accumulations of uranium redistributed by reduction-oxidation processes from preexisting primary deposits.Within the ores, whole-rock abundances of organic carbon correlate positively with uranium contents. This correlation is consistent with petrologic evidence which indicates that uranium is everywhere intimately admixed with the amorphous organic material. Ore zones are also enriched in vanadium (as ore-stage vanadiferous chlorite) and sulfur (as ore-stage iron disulfide minerals with delta&nbsp;</span><sup>34</sup><span>&nbsp;S values ranging from -29 to -42ppm).Petrographic observations demonstrate that Smith Lake uranium mineralization occurred early (before major burial compaction) in the paragenetic sequence of host-rock diagenetic alterations but was preceded by precipitation of authigenic iron disulfides (delta&nbsp;</span><sup>34</sup><span>&nbsp;S values ranging from -11 to -38ppm), mixed-layered smectite-illite clays, and potassium feldspars.Additional preore alterations included dissolution of detrital sanidine and plagioclase and the leaching of iron from detrital iron-titanium oxide grains. Following mineralization, varying amounts of authigenic calcite and barite formed, both of which were partly replaced by kaolinitc. Oxidation of some previously formed iron disulfide minerals occurred late in the paragenetic sequence, as did localized precipitation of native selenium, pyrite, and very minor amounts of uranium minerals.The positive correlation between contents of uranium and organic carbon and the admixture of uranium with the amorphous organic material indicates that the Mariano Lake and Ruby 1 deposits are primary-type uranium orebodies. The offset of orebodies by Laramide faults and radiometric age determinations of the ores are also consistent with a primary origin for the deposits. Late Tertiary oxygenated ground waters locally modified original chemical and mineralogical characteristics of the ores in part by leaching some uranium. Secondary uranium minerals precipitated from the partly leached primary ores are sparse in the mine area; such recycled uranium appears to represent an insignificant proportion of the total uranium in the Smith Lake district.</span></p>","language":"English","publisher":"Society of Economic Geologists","doi":"10.2113/gsecongeo.80.5.1348","issn":"03610128","usgsCitation":"Fishman, N., Reynolds, R.L., and Robertson, J., 1985, Uranium mineralization in the Smith Lake district of the Grants uranium region, New Mexico.: Economic Geology, v. 80, no. 5, p. 1348-1364, https://doi.org/10.2113/gsecongeo.80.5.1348.","productDescription":"17 p.","startPage":"1348","endPage":"1364","numberOfPages":"17","costCenters":[],"links":[{"id":222554,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"80","issue":"5","noUsgsAuthors":false,"publicationDate":"1985-08-01","publicationStatus":"PW","scienceBaseUri":"505bbdc2e4b08c986b3291eb","contributors":{"authors":[{"text":"Fishman, N.S.","contributorId":59441,"corporation":false,"usgs":true,"family":"Fishman","given":"N.S.","email":"","affiliations":[],"preferred":false,"id":364430,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Reynolds, R.

While engineers use the peak ground acceleration (PGA) to model the strong ground motion, seismologists use physical characteristics of the source and the rupture mechanism, such as fault length, stress drop, shear wave velocity, seismic moment, distance, and attenuation. This study presents a method for calculating response spectra from seismological models using random vibration theory. It then investigates the effect of various source and site parameters on peak response. Calculations are based on a nonstationary stochastic ground motion model, which can incorporate all the parameters both in frequency and time domains. The estimation of the peak response accounts for the effects of the non-stationarity, bandwidth and peak correlations of the response.","conferenceTitle":"Soil Dynamics and Earthquake Engineering, Proceedings of the 2nd International Conference.","conferenceLocation":"Aboard the Queen Elizabeth 2, New York to Southampton","language":"English","publisher":"Computational Mechanics Ltd","publisherLocation":"Southampton, Engl","isbn":"0905451341","usgsCitation":"Safak, E., 1985, SENSITIVITY OF STRUCTURAL RESPONSE TO GROUND MOTION SOURCE AND SITE PARAMETERS., Soil Dynamics and Earthquake Engineering, Proceedings of the 2nd International Conference., Aboard the Queen Elizabeth 2, New York to Southampton.","costCenters":[],"links":[{"id":220173,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505aaf35e4b0c8380cd87453","contributors":{"editors":[{"text":"Brebbia, C.A.","contributorId":112425,"corporation":false,"usgs":true,"family":"Brebbia","given":"C.A.","affiliations":[],"preferred":false,"id":508473,"contributorType":{"id":2,"text":"Editors"},"rank":1},{"text":"Cakmak, A.S.","contributorId":114101,"corporation":false,"usgs":true,"family":"Cakmak","given":"A.S.","email":"","affiliations":[],"preferred":false,"id":508475,"contributorType":{"id":2,"text":"Editors"},"rank":2},{"text":"Ghaffar, Abdel","contributorId":113250,"corporation":false,"usgs":true,"family":"Ghaffar","given":"Abdel","email":"","affiliations":[],"preferred":false,"id":508474,"contributorType":{"id":2,"text":"Editors"},"rank":3}],"authors":[{"text":"Safak, Erdal","contributorId":73984,"corporation":false,"usgs":true,"family":"Safak","given":"Erdal","email":"","affiliations":[],"preferred":false,"id":365172,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

In the equatorial region, where most of the valleys are observed, even ice is unstable3,4. It has been suggested, therefore, that Mars had an early denser atmosphere with sufficient greenhouse warming to allow the existence of liquid water 5. Here, we suggest instead that during periods of very high obliquities, ice could accumulate at low latitudes as a result of sustained sublimation of ice from the poles and transport of the water vapour equatorwards. At low latitudes, the water vapour would saturate the atmosphere and condense onto the surface where it would accumulate until lower obliquities prevailed. The mechanism is efficient only at the very high obliquities that occurred before formation of Tharsis very early in the planet's history, but limited equatorial ice accumulation could also have occurred at the highest obliquities during the rest of the planet's history. Partial melting of the ice could have provided runoff to form the channels or replenish the groundwater system. ?? 1985 Nature Publishing Group.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Nature","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1038/315559a0","issn":"00280836","usgsCitation":"Jakosky, B., and Carr, M.H., 1985, Possible precipitation of ice at low latitudes of Mars during periods of high obliquity: Nature, v. 315, no. 6020, p. 559-561, https://doi.org/10.1038/315559a0.","startPage":"559","endPage":"561","numberOfPages":"3","costCenters":[],"links":[{"id":205008,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1038/315559a0"},{"id":220122,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"315","issue":"6020","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a7e35e4b0c8380cd7a3d2","contributors":{"authors":[{"text":"Jakosky, B.

A sequence of submarine volcanic rocks of predominantly Early Devonian age is the principal component of the island-arc terrane in which the sulfide deposits are hosted. The Copley Greenstone, consisting mainly of andesitic and basaltic pillow lavas and breccias totaling at least 1,800 m in thickness, is the oldest rock unit in the sequence. It is overlain and also intruded by dikes of the Balaklala Rhyolite. Northeast of the West Shasta district, greenstone also overlies the Balaklala Rhyolite, suggesting that a major greenstone unit may overlie potentially mineralized rhyolite east of the district. However, recent studies have shown that the complex relations in that area can be explained by folding.The Balaklala sequence consists of silicic flows, breccias, and tuffs having a maximum thickness somewhat in excess of 1,000 m. The Balaklala has been divided by Kinkel et al. (1956) into three units: a lower nonporphyritic to slightly porphyritic unit containing large amounts of breccia and tuff; a middle unit characterized by rhyolite containing quartz phenocrysts 1 to 4 mm in diameter but also containing a complex assortment of tuff, breccia, and pyritic massive sulfide bodies in its upper part; and an upper unit typically containing dark quartz phenocrysts in excess of 4 mm in diameter. Much of the lower part of the upper unit is pyroclastic material, whereas most of the upper part of the unit appears to be a massive volcanic-flow rock. At least half a dozen eruptive centers for the Balaklala Rhyolite are identified, three of them within an area measuring 17 X 3 km that constitutes the limits of the former mining district.The youngest unit in the arc sequence is the Kennett Formation consisting of black shale and chert containing radiolarians, which indicate fairly deep-water deposition in its lower part, and limestone containing a shallow water fauna of probable Middle Devonian age in the upper part. A 400-m.y.-old trondhjemite stock, named the Mule Mountain stock, intrudes the Copley Greenstone and Balaklala Rhyolite and is considered to be essentially coeval with these volcanic units.The pyritic massive sulfide deposits occur in clusters of individual bodies owing in large part to disruption by postmineral faults. The deposits are stratigraphically confined to the upper part of the subhorizontal middle unit of the Balaklala, and their horizontal distribution is here interpreted to have been controlled by an extensional tectonic regime that prevailed during Early Devonian time. The major geologic evidence for such a regime is the marked preferred elongations exhibited by the distribution of the afore-mentioned eruptive centers, the eight or nine massive sulfide clusters in the district, and the geometrically similar distribution of the clusters in relation to each other. The preferred directions of elongation in both the detailed and broader senses may be generalized to N 20 degrees to 25 degrees E, N 37 degrees E, N 60 degrees to 80 degrees E, and N 40 degrees to 60 degrees W. The three northeast trends dominate throughout the district, whereas the northwest trend is evident mainly in the northern part and is more speculative. The major deposit clusters fall at intersections of the major trends, some of which may have been grabens. Trend intersections having no known deposits may be good exploration targets in localities where the stratigraphically favorable middle unit of the Balaklala is still present.</span></p>","language":"English","publisher":"Society of Economic Geologists","doi":"10.2113/gsecongeo.80.8.2072","issn":"03610128","usgsCitation":"Albers, J.P., and Bain, J., 1985, Regional setting and new information on some critical geologic features of the West Shasta district, California: Economic Geology, v. 80, no. 8, p. 2072-2091, https://doi.org/10.2113/gsecongeo.80.8.2072.","productDescription":"20 p.","startPage":"2072","endPage":"2091","numberOfPages":"20","costCenters":[],"links":[{"id":219834,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"80","issue":"8","noUsgsAuthors":false,"publicationDate":"1985-12-01","publicationStatus":"PW","scienceBaseUri":"50e4a577e4b0e8fec6cdbe12","contributors":{"authors":[{"text":"Albers, J.

In the forecast procedure proposed here, repeated measurements of preseismic fault slip and ground deformation constrain the values of model parameters. The early part of the model simulation corresponds to the available field data, and the subsequent part constitutes an estimate of future faulting and ground deformation. In particular, the time, location, and size of unstable faulting are estimates of the pending earthquake parameters. The forecast accuracy depends on the model realism and parameter resolution. The forecast procedure is applied to fault creep and trilateration data measured near Parkfield, California, where at least five magnitude 5.5 to 6 earthquakes have occurred regularly since 1881, the last in 1966. The quasi-static model consists of a flat vertical plane embedded in an elastic half space. Spacially variable fault slip of strike-slip sense is driven by an increasing regional shear stress but is impeded by a relatively strong patch of brittle, strain-softening fault. The field data are consistent with these approximate values of patch parameters: radius of 3 km, patch center 5 km deep and 8 km southeast of the 1966 epicenter, and maximum brittle strength of 26 bars. Fluctuations in the available field data prevent estimating the earthquake time with any more precision than use of the 21±8 year recurrence interval. However, the model may later give a more precise estimate of the earthquake time if the fault slip rate near the inferred patch increases before the earthquake, as predicted by the model.</span></p>","language":"English","publisher":"American Geophysical Union","doi":"10.1029/JB090iB01p00592","issn":"01480227","usgsCitation":"Stuart, W.D., Archuleta, R.J., and Lindh, A.G., 1985, Forecast model for moderate earthquakes near Parkfield, California: Journal of Geophysical Research Solid Earth, v. 90, no.

The following discussion centers on the role of modern XRF instrumentation in the resolution of geochemical problems.

Minerals such as quartz, calcite, and pyrite as well as macerals such as vitrinite can originate from a variety of processes that result from different depositional conditions. The Upper Freeport coal bed was studied and characterized by sampling and analyzing its mappable subunits (facies) over a 120-sq mi area in west-central Pennsylvania. The study was based on field description of mine faces and description of X-ray radiographs of core. A geochemical model proposed for the origin of facies of the Upper Freeport coal bed is consistent with interpretations of modern peat formation resulting from the interaction of climate, plant types, rainfall, ground water geochemistry, nutrient supply, and sedimentation.

Cape Riva (CR) eruption of Santorini vented several km3 or more of magma, generating four eruption units: a basal Plinian fall deposit (CR-A) and three pyroclastic flow deposits (CR-B to CR-D upwards). CR-B and CR-D are welded ignimbrites; CR-C consists predominantly of up to 25 m thick coarse, lithic-rich co-ignimbrite lag breccias resulting from a climactic phase of the eruption. The initial Plinian phase occurred from a localized vent in N Santorini, and subsequent column collapse resulted in emplacement of CR-B. Towards the end of CR-B, new conduits were activated and pyroclastic flows discharged from multiple vents to generate the lag breccias (CR-C). CR-D probably records a return to a localized vent as the eruption waned. The eruption sampled a zoned magma chamber containing rhyodacite overlying andesite, and leaks of these magmas were manifested as the Skaros-Therasia lavas preceding the CR eruption. Plinian and initial ignimbrite stages occurred while the magma chamber was overpressured; subsequent underpressuring, due to magma discharge, caused fracturing of the chamber roof, caldera collapse, and eruption of pyroclastic flows from multiple vents. Activation and widening of new conduits during collapse resulted in the rapid escalation of discharge rate favoring the formation of lag breccias by: (i) promoting erosion of lithic debris at the surface vent; and (ii) raising surface exit pressures, thereby resulting in a dramatic increase in the grain size of the ejecta.</span></p>","language":"English","publisher":"University of Chicago Press","doi":"10.1086/628965","issn":"00221376","usgsCitation":"Druitt, T.H., 1985, Vent evolution and lag breccia formation during the Cape Riva eruption of Santorini, Greece: Journal of Geology, v. 93, no. 4, p. 439-454, https://doi.org/10.1086/628965.","productDescription":"16 p.","startPage":"439","endPage":"454","numberOfPages":"16","costCenters":[],"links":[{"id":220345,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"93","issue":"4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505bc201e4b08c986b32a89e","contributors":{"authors":[{"text":"Druitt, T.

The project goal was to develop empirical models for predicting rainbow trout growth rates from the following variables: total phosphorus concentration, chlorophyll a concentration, Secchi disc transparency, or the morphoedaphic index--a means of characterizing potential biological productivity. No suitable model could be developed from the data collected during 1982 and 1983. The lack of significant correlation was attributed in part to the wide variation in survival of rainbow trout. Winterkills, caused by severe depletion of dissolved oxygen, were suspected in four of the lakes. Varied levels of fishing pressure and competition with threespine stickleback (Gasterosteus aculeatus) also influenced survival of rainbow trout but their effects were overshadowed by winterkill. Predictive capability was also reduced because of inconsistencies in rankings generated by each of the four limnological variables chosen as indicators of potential biological productivity. A lake ranked low in productivity by one variable was commonly ranked high in productivity by another variable. The survivability of rainbow trout stocked in lakes such as these nine may be a more important indicator of potential biomass production than are indicators of lake fertility. Assessments of a lake 's susceptibility to winterkill and the degree of competition with threespine stickleback are suggested as important topics for additional research.&nbsp;</p>","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/wri854292","usgsCitation":"Woods, P.F., 1985, Limnology of nine small lakes, Matanuska-Susitna Borough, Alaska, and the survival and growth rates of rainbow trout: U.S. Geological Survey Water-Resources Investigations Report 85-4292, iv, 32 p., https://doi.org/10.3133/wri854292.","productDescription":"iv, 32 p.","costCenters":[],"links":[{"id":414141,"rank":3,"type":{"id":36,"text":"NGMDB Index Page"},"url":"https://ngmdb.usgs.gov/Prodesc/proddesc_36430.htm","linkFileType":{"id":5,"text":"html"}},{"id":59341,"rank":2,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/wri/1985/4292/report.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":123988,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/wri/1985/4292/report-thumb.jpg"}],"country":"United States","state":"Alaska","otherGeospatial":"Matanuska-Susitna Borough, Alaska","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"coordinates\": [\n          [\n            [\n              -149.817,\n              61.833\n            ],\n            [\n              -149.817,\n              61.45\n            ],\n            [\n              -148.267,\n              61.45\n            ],\n            [\n              -148.267,\n              61.833\n            ],\n            [\n              -149.817,\n              61.833\n            ]\n          ]\n        ],\n        \"type\": \"Polygon\"\n      }\n    }\n  ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4b15e4b07f02db6a50f9","contributors":{"authors":[{"text":"Woods, P.
