Ground-water contamination by DIMP from the disposal of wastes into unlined surface ponds at the Rocky Mountain Arsenal occurred from 1952 to 1956. A digital-transport model was used to determine the effects on ground-water movement and on DIMP concentrations in the ground water of a bentonite barrier in the aquifer near the northern boundary of the arsenal. The transport model is based on an iterative-alternating- direction-implicit mathematical solution of the ground-water-flow equation coupled with a method-of-characteristics solution of the solute-transport equation. The model assumes conservative (nonreactive) transient transport of DIMP and steady-state ground-water flow.</p><p>In the model simulations, a bentonite barrier was assumed that was impermeable and penetrated the entire saturated thickness of the aquifer. Ground water intercepted by the barrier was assumed to be pumped by wells located south (upgra-dient) of the barrier, to be treated to remove DIMP, and to be recharged by pits or wells to the aquifer north (downgradient) of the barrier. The amount of DIMP transported across the northern boundary of the arsenal was substantially reduced by a ground-water-barrier system of this type. For a 1,500-foot-long bentonite barrier located along the northern boundary of the arsenal near D Street, about 50 percent of the DIMP that would otherwise cross the boundary would be intercepted by the barrier. This barrier configuration and location were proposed by the U.S. Army. Of the ground water with DIMP concentrations greater than 500 micro- grams per liter, the safe DIMP-concentration level determined by the U.S. Army, about 72 percent would be intercepted by the barrier system. The amount of DIMP underflow intercepted may be increased to 65 percent by doubling the pumpage, or to 73 percent by doubling the length of the barrier.</p>","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/ofr79676","usgsCitation":"Warner, J.W., 1979, Digital-transport model study of Diisopropylmethylphosphonate (DIMP) ground-water contamination at the Rocky Mountain Arsenal, Colorado: U.S. Geological Survey Open-File Report 79-676, iv, 39 p., https://doi.org/10.3133/ofr79676.","productDescription":"iv, 39 p.","costCenters":[],"links":[{"id":431102,"rank":2,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1979/0676/report.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":145370,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/1979/0676/report-thumb.jpg"}],"country":"United States","state":"Colorado","otherGeospatial":"Rocky Mountain Arsenal","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"coordinates\": [\n          [\n            [\n              -104.90350277918196,\n              39.79818526609469\n            ],\n            [\n              -104.77217640835627,\n              39.79820512226806\n            ],\n            [\n              -104.77179948807711,\n              39.87074264337295\n            ],\n            [\n              -104.86486845062375,\n              39.87059800145718\n            ],\n            [\n              -104.90350277918196,\n              39.83770284193764\n            ],\n            [\n              -104.90350277918196,\n              39.79818526609469\n            ]\n          ]\n        ],\n        \"type\": \"Polygon\"\n      }\n    }\n  ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a82e4b07f02db64acd1","contributors":{"authors":[{"text":"Warner, James W.","contributorId":106119,"corporation":false,"usgs":true,"family":"Warner","given":"James","email":"","middleInitial":"W.","affiliations":[],"preferred":false,"id":163387,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

A brief evaluation was made of a modified version of the model that simulates quality of urban runoff.

Some notable simulation results were that a 25 percent storm-sewer slope reduction yielded only a 3 percent peak-discharge reduction, and increasing storm-sewer roughness by increasing Manning's \"n\" from 0.013 to 0.0^0 decreased peak discharge about 10 to 20 percent. Detention of 10 percent of runoff throughout each basin yielded peak-discharge reductions of about 10 to 20 percent. Infiltration of all parking-lot runoff reduced peak discharges 5 to 2h percent. Peak discharges were reduced by 71 to 88 percent by substituting porous pavement for conventional pavement. Draining 90 percent of the residential rooftops onto lawns instead of driveways reduced peak discharge from 7 to 31 percent. Runoff-volume reduction was similarly reduced for the induced infiltration simulations.</p>\n<p>Storage requirements for hypothetical storm-water-treatment plants ranged from 2.6 to 29 acre-feet for the smallest and largest basins, respectively, with a treatment capacity of 25 cubic feet per second.</p>\n<p>A brief inconclusive evaluation of the water-quality subroutines of the model was made. Close agreement was noted between observed and simulated loads for nitrates, organic nitrogen, total phosphate, and total solids.

Development of processes that concentrate and pelletize low-grade iron ore has permitted mining to expand during the past two decades. Water demand has increased both for iron ore concentration processes and for the area 's general development. </p><p>Five main streams drain the area. Their total average annual discharge is about 700 cu ft/sec, of which, about 150 cu ft/sec is inflow from outside of this study 's limits. The Middle Branch and East Branch Escanaba River flow through the central part of the study area and drain about 60 percent of it. The combined natural flow of these two streams equals or exceeds 100 cu ft/sec 90 percent of the time. Median annual 7-day low-flows are about 0.25 cu ft/sec per sq mi in most of the area. Seven stream impoundments and 243 natural lakes provide surface water storage. </p><p>Surface water is generally of a calcium-magnesium bicarbonate type and dissolved-solids concentrations are generally less than 150 mg/L. Small streams that drain glacial outwash deposits have higher dissolved-solids concentrations than larger streams. </p><p>Large ground-water supplies may be developed from glacial outwash aquifers along the northern, southern, and eastern boundaries of the study area. Thin, unconsolidated deposits of low permeability occur in the center of the area. Metamorphosed bedrock produces moderate amounts of water only in fracture zones. Sandstones in the eastern part of the area yield water at some locations, but these deposits are seldom utilized because other ground-water sources are more readily available. </p><p>Ground water in the Marquette Iron Range is generally of suitable quality for most uses. Iron concentrations, however, are frequently high.</p>","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/ofr791339","collaboration":"Prepared in cooperation with the Michigan

Surface-water studies were made to analyze long-term records of streamflow, basin and stream-channel characteristics, relations of rainfall and runoff , frequency of low flows and floods, interrelation of ground and surface water, and the effects of stream regulation on the quantity, quality, and availability of water supplies. Geohydrologic studies were made to determine the source, availability, quantity, and quality of water in the principal aquifers; evaluate long-range effects of irrigation, industrial, and municipal withdrawals; determine the potential for storage of liquid wastes; and prepare digital models for evaluating plans of aquifer development and management. Water-quality studies were made to define the physical, chemical, and biological character of surface and ground water; the origin transport, and character of solutes and sediment in streams; the areal and temporal changes in water quality; and the suitability of water for municipal, industrial and agricultural use.</p>","language":"English","publisher":"U.S. Geological

A digital model calibrated to conditions in Cedar Creek was used to develop alternatives for future waste loadings that would be compatible with Indiana stream water-quality standards defined for two critical hydrologic conditions, summer and winter low flows. All point-source waste loads affecting Cedar Creek are in the four incorporated municipalities of Auburn, Garrett, Huntertown, and Waterloo, in a primarily agricultural area. Avilla, because of its distance from Cedar Creek, does not significantly affect the water quality of the modeled segment.</p><p>The model indicates that the dissolved-oxygen concentration of the Auburn wastewater effluent and nitrification are the most significant factors affecting the dissolved-oxygen concentration in Cedar Creek during summer low flows. The observed dissolved-oxygen concentration of the Auburn wastewater effluent was low, and averaged 30 percent of saturation. Whether the effluent is aerated before discharge will ultimately define the waste-load assimilative capacity of Cedar Creek. Projected nitrogenous biochemical-oxygen demand loads, from the Indiana State Board of Health, for the Auburn and Waterloo wastewater-treatment facilities will result in violations of the current instream dissolved-oxygen standard (5 milligrams per liter), even with an effluent dissolved-oxygen concentration of 80 percent saturation.</p><p>Natural streamflow for Cedar Creek upstream from the confluence of Willow and Little Cedar Creeks is small compared with the waste discharge, so benefits of dilution for Waterloo and Auburn are minimal. Stream reaeration capacity is not sufficient to maintain an average dissolved-oxygen concentration of at least 5 milligrams per liter, the State's water-quality standard for streams.</p><p>The model also indicates that, during winter low flows, ammonia toxicity, rather than dissolved oxygen, is the limiting water-quality criterion in the reach of Cedar Creek downstream from the wastewater-treatment facility at Auburn and the confluence of Garrett ditch. Ammonia-nitrogen concentrations predicted for 2978 through 2000 downstream from the Waterloo wastewater-treatment facility do not exceed Indiana water-quality standards for streams.</p><p>Calculations of the stream's assimilative capacity indicate that future waste discharge in the Cedar Creek basin will be limited to the reaches between the Auburn wastewater-treatment facility and County Road 68.</p>","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/ofr791062","collaboration":"Prepared in cooperation with the Indiana State Board of Health","usgsCitation":"Wilber, W.G., Peters, J.G., Ayers, M.A., and Crawford, C.G., 1979, A one-dimensional, steady-state dissolved-oxygen model and waste-load assimilation study for Cedar Creek, Dekalb and Allen counties, Indiana: U.S. Geological Survey Open-File Report 79-1062, viii, 79 p., https://doi.org/10.3133/ofr791062.","productDescription":"viii, 79 p.","onlineOnly":"N","additionalOnlineFiles":"N","costCenters":[],"links":[{"id":422925,"rank":2,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1979/1062/report.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":140364,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/1979/1062/report-thumb.jpg"}],"country":"United States","state":"Indiana","county":"Allen County, Dekalb County","otherGeospatial":"Cedar Creek","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"coordinates\": [\n          [\n            [\n              -85.38216090798966,\n              41.60787742256892\n            ],\n            [\n              -85.38216090798966,\n              41.14208690200232\n            ],\n            [\n              -84.81087184548976,\n              41.14208690200232\n            ],\n            [\n              -84.81087184548976,\n              41.60787742256892\n            ],\n            [\n              -85.38216090798966,\n              41.60787742256892\n            ]\n          ]\n        ],\n        \"type\": \"Polygon\"\n      }\n    }\n  ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4b20e4b07f02db6abb2c","contributors":{"authors":[{"text":"Wilber, William G. wgwilber@usgs.gov","contributorId":297,"corporation":false,"usgs":true,"family":"Wilber","given":"William","email":"wgwilber@usgs.gov","middleInitial":"G.","affiliations":[],"preferred":true,"id":155417,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Peters, James G.","contributorId":69137,"corporation":false,"usgs":true,"family":"Peters","given":"James","email":"","middleInitial":"G.","affiliations":[],"preferred":false,"id":155420,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Ayers, Mark A.","contributorId":84730,"corporation":false,"usgs":true,"family":"Ayers","given":"Mark","email":"","middleInitial":"A.","affiliations":[],"preferred":false,"id":155419,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Crawford, Charles G. 0000-0003-1653-7841 cgcrawfo@usgs.gov","orcid":"https://orcid.org/0000-0003-1653-7841","contributorId":1064,"corporation":false,"usgs":true,"family":"Crawford","given":"Charles","email":"cgcrawfo@usgs.gov","middleInitial":"G.","affiliations":[{"id":37947,"text":"Upper Midwest Water Science Center","active":true,"usgs":true},{"id":451,"text":"National Water Quality Assessment Program","active":true,"usgs":true}],"preferred":true,"id":155418,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

The calibrated model supported the hypothesis that under natural steady-state conditions, recharge is from precipitation and discharge is through evapotranspiration. This hypothesis was further supported by comparing simulated water levels to observed water levels collected during a 3-year period of irrigation withdrawal.</p>\n<p>Predictions of the effects of continued withdrawal of currently allocated water were made. One prediction using recharge equal to 25 percent of the average annual precipitati on showed that an equilibrium between pumping and recharge would be established within 10 years and water levels would be 2 to 4 feet below 1977 levels .

The total area covers about 620 km<sup>2</sup> (237 sq mi) in the Sierra and Inyo National Forests, of which about 440 km<sup>2</sup> (170 sq mi) are within the officially designated Minarets Wilderness.</p><p>The mineral resource potential was evaluated by geological, geochemical, and geophysical studies by the U.S. Geological Survey, and by examination of mineralized rocks, prospects, and mining claims by the U.S. Bureau of Mines.</p><p>The results of the survey indicate that the study area has small to moderate submarginal to paramarginal resources of copper, silver, zinc, lead, iron, and tungsten and an unevaluated potential for molybdenum resources. Limestone is present, but not of commercial quantity or quality. No other industrial minerals have been recognized in quantity. Granitic rocks have potential use as decorative stone and sand and gravel could be produced from either alluvial deposits or glacial drift. However, these commodities are more accessible elsewhere at localities closer to markets. The study area has no potential for fossil fuels, and, because of the general geologic environment, the potential for nuclear fuel minerals is considered to be low. The study area has low geothermal potential, even though it is on the western edge of the Mono-Long Valley \"Known Geothermal Resource Area\" (KGRA).</p><p>The area is underlain by metavolcanic and metasedimentary rocks that have been intruded by granitic rocks of the Sierra Nevada batholith. Pliocene volcanic rocks are present locally. With few exceptions, the known occurrences of mineralized rock are confined to the metamorphic rocks, and the exceptions appear to be confined to plutonic rocks that are older than the Late Cretaceous granitic rocks that make up the bulk of the batholithic rocks in the study area.</p><p>Although no mineral production has been recorded from prospects within the study area, mines adjacent to it have produced significant amounts of gold and tungsten. Production figures are incomplete, but mines in the Mammoth mining district (fig. 1) may have produced as much as $1 million worth of gold, silver, and other metals at the then-existing prices. The Monte Cristo mine in the Mammoth district was in production during 1978.</p>","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/ofr791472","usgsCitation":"Huber, N.K., Oliver, H.W., Bailey, R.A., and U.S. Bureau of Mines, 1979, Mineral resources of the Minarets Wilderness and adjacent areas, Madera and Mono counties, California: U.S. Geological Survey Open-File Report 79-1472, Report: xi, 183 p.; 3 Plates: 30.35 x 52.68 inches or smaller, https://doi.org/10.3133/ofr791472.","productDescription":"Report: xi, 183 p.; 3 Plates: 30.35 x 52.68 inches or smaller","costCenters":[],"links":[{"id":431032,"rank":5,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/1979/1472/plate-1.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":431031,"rank":4,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/1979/1472/plate-2.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":431029,"rank":2,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1979/1472/report.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":142864,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/usgs_thumb.jpg"},{"id":431030,"rank":3,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/1979/1472/plate-3.pdf","linkFileType":{"id":1,"text":"pdf"}}],"scale":"62500","country":"United States","state":"California","county":"Madera County, Mono County","otherGeospatial":"Minarets Wilderness","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"coordinates\": [\n          [\n            [\n              -119.35182738671992,\n              37.80567055700155\n            ],\n            [\n              -119.35182738671992,\n              37.620776977513216\n            ],\n            [\n              -119.09698827321262,\n              37.620776977513216\n            ],\n            [\n              -119.09698827321262,\n              37.80567055700155\n            ],\n            [\n              -119.35182738671992,\n              37.80567055700155\n            ]\n          ]\n        ],\n        \"type\": \"Polygon\"\n      }\n    }\n  ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4b06e4b07f02db69a1f2","contributors":{"authors":[{"text":"Huber, N.

Record low amounts of rainfall, snowfall, and runoff, and increased withdrawals of ground water were prevalent. The use of carry-over storage in reservoirs during 1976 maintained streamflow at near normal levels, but some reservoirs went dry or dropped below the outlet works in 1977. Carry-over storage in the fall of 1977 was very low. Ground-water levels were at or near record low levels in many aquifers, hundreds of wells went dry, and thousands of wells were drilled. Yet no wide-spread deterioration of ground-water quality was reported. Water-quality problems arose in some streams and lakes, but most were localized and of short duration. Water rationing became a way of life in numerous areas , and water was hauled in many rural areas and to a few towns. Water use was affected by legal agreements or decisions, some of which were modified for the duration of the drought, and by the inability of water managers to efficiently manage surface and ground waters as one resource under existing law. There are still many drought related problems to solve and many challenges to be met before the next drought occurs. The advancement of techniques in many fields of endeavor in recent years plus ongoing, planned, and proposed research on drought and the risks involved are promising thrusts that should make it easier to cope with the next drought.

Flow in this reach of the Chattahoochee is continuous but highly regulated by Buford Dam, a flood-control and hydroelectric facility located near Buford, Ga. Calibration and verification utilized two sets of data collected under highly unsteady discharge conditions. Existing solution techniques, with certain minor improvements, were applied to verify the existing technology of flow and transport modeling. \r\n\r\nThe linear, implicit finite-difference flow model was calibrated by use of a depth profile obtained at steady low flow and unsteady flow data obtained in March 1976. During the calibration period, the model was generally able to reproduce observed stages to within 0.15 m and discharges at less than 100 m 3 /s, to within 5 percent. Peak discharges of about 200 m 3 /s were under-estimated by about 20 percent. During the verification period, October 1975, the flow model reproduced observed stage changes to within about 0.15 m, and its timing and over-all performance was considered to be very good. \r\n\r\nDye was added to the upstream end of the river reach at a constant rate while the river flow was highly unsteady. The numerical solution of either the conservative or nonconservative form of the mass-transport equation did an excellent job of simulating the observed concentrations of dye in the river. \r\n\r\nThe temperature model was capable of predicting temperature changes through this reach of as large as 5.8?C with a RMS (root-mean-square) error of 0.32?C in October 1975 and 0.20?C in March 1976. \r\n\r\nHydropulsation has a significant effect on the water temperature below Buford Dam. These effects are very complicated because they are quite dependent on the timing of the release with respect to both the time of day and past releases.","language":"ENGLISH","publisher":"U.S. Govt.

Several Paleogene nonmarine arkosic sandstone units fringe and in part occur within the complex crystalline core. The early to middle Eocene Chuckanut Formation is present on the west side of the crystalline core in the western foothills of the Cascades. The early to middle Eocene Swauk Formation partially encircles the Mt. Stuart massif of the central Cascades. In the western foothills of the Cascades, between the main body of Chuckanut Formation near Bellingham and the main outcrop area of the Swauk Formation south of Mt. Stuart, many smaller bodies of arkosic sandstone have variously been referred to either the Swauk or Chuckanut Formations. The early Eocene Manastash Formation occurs locally in an area south of the Yakima River. The middle to late Eocene Chumstick Formation is mostly confined to the Chiwaukum graben within the crystalline core and is separated from the Swauk Formation on the southwest by the Leavenworth Fault. The Oligocene Wenatchee Formation unconformably over lies the Chumstick Formation near Wenatchee. The middle to late Eocene Roslyn Formation crops out north of the Yakima River and is underlain by the Teanaway Basalt which separates the Roslyn from the older Swauk Formation. The middle Eocene to early Oligocene Naches Formation forms a north-trending body that crosses the Yakima River and is in fault contact with both the Swauk and Manastash Formations. The middle to late Eocene Puget Group underlies the Quaternary deposits of the Puget Lowland southeast of Seattle on the western flank of the Cascades.\r\n\r\nThe various formations are all composed predominantly of fine- to medium-grained sandstones with lesser amounts of interbedded shale, conglomerate and coal. Compositionally, the units are predominantly either feldspathic or litho-feldspathic subquartzose sandstones. Volcanic rocks are important constituents of the Puget Group, the \r\nChumstick and Naches Formations, and the isolated arkosic bodies. The three older units, however, contain relatively less volcanic lithics to total lithics than do younger units, indicating perhaps the initiation of more widespread volcanic activity in middle Eocene time. Ratios of framework grain parameters show that the terrestrial sandstone units were derived from a mixed plutonic and tectonic source terrane of continental block tectonic provenance with an overprint of magmatic arc provenance. \r\n\r\nModal analysis was performed on samples from the various sedimentary units to establish petrologic compositions, and to provide data with which to compare the different units and discuss clast provenance and tectonic regimen. Although the arkosic sandstones have generally uniform framework clast compositions, minor yet significant differences do exist between the units. Basal or basement-onlap portions of the units in particular are locally derived and differ markedly from the overall compositions of the individual units. Many coincidences of composition, age, structure, and bedrock indicate that the Chuckanut and Swauk may have originally been deposited as a single unit that since has been offset approximately 160 kilometers by right lateral strike slip motion starting about 48 Ma. If this hypothetical offset did occur, then major movement on the Straight Creek Fault is bracketed between about 48 Ma and Oligocene time.","language":"ENGLISH","publisher":"U.S. Geological Survey,","doi":"10.3133/ofr791149","usgsCitation":"Frizzell, V.A., 1979, Petrology and stratigraphy of Paleogene nonmarine sandstones, Cascade Range, Washington: U.S. Geological Survey Open-File Report 79-1149, ix, 151 p, 3 over-size sheets., maps (some fold. in envelope) ;28 cm., https://doi.org/10.3133/ofr791149.","productDescription":"ix, 151 p, 3 over-size sheets., maps (some fold. in envelope) ;28 cm.","costCenters":[],"links":[{"id":141117,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/1979/1149/report-thumb.jpg"},{"id":36529,"rank":400,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/1979/1149/plate-1.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":36530,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1979/1149/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4adde4b07f02db686a5b","contributors":{"authors":[{"text":"Frizzell, Virgil A.","contributorId":87934,"corporation":false,"usgs":true,"family":"Frizzell","given":"Virgil","email":"","middleInitial":"A.","affiliations":[],"preferred":false,"id":158554,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

This greenschist terrane is bordered on the east and west by rocks belonging to the amphibolite metamorphic facies that structurally overlie and are thrust over the Condrey Mountain Schist. The amphibolite facies is succeeded upward by metavolcanic and metasedimentary rocks belonging to the greenschist metamorphic facies. \r\n\r\nThe Condrey Mountain Schist is composed predominantly of quartz-muscovite schist and lesser amounts of actinolite-chlorite schist formed by the metamorphism of graywacke and spilitic volcanic rocks that may have belonged to the Galice Formation of Late Jurassic age. Potassium-argon age determinations of 141?4 m.y. and 155?5 m.y. obtained on these metamorphic rocks seem to be incompatible with the Late Jurassic age usually assigned the Galice. \r\n\r\nThe rocks that border the amphibolite facies are part of an extensive terrane of metavolcanic and metasedimentary rocks belonging to the western Paleozoic and Triassic belt. The metavolcanic rocks include some unmetamorphosed spilite but are mostly of the greenschist metamorphic facies composed of oligoclase (An15-20) and actinolite with subordinate amounts of chlorite and clinozoisiteepidote. The interbedded sedimentary rocks are predominantly argillite and slaty argillite, less commonly siliceous argillite and chert, and a few lenticular beds of marble. On the south, high-angle faults and a tabular granitic pluton separate the greenschist metavolcanic terrane from the amphibolite facies rocks; on the east, nonfoliated amphibolite is succeeded upward, apparently conformably, by metasedimentary rocks belonging to the greenschist metavolcanic terrane. \r\n\r\nIn the southern part of Condrey Mountain quadrangle, an outlier of a thrust plate composed of the Stuart Fork Formation overlies the metavolcanic and metasedimentary rocks. The Stuart Fork in this region is composed of siliceous phyllite and phyllitic quartzite and is believed to be the metamorphosed equivalent of rocks over which it is thrust. In the Yreka-Fort Jones area, potassium-argon determinations on mica from the blueschist facies in the Stuart Fork gave ages of approximately 220 m.y. (Late Triassic) for the age of metamorphism. \r\n\r\nRocks of the amphibolite facies structurally overlie the Condrey Mountain Schist along a moderate to steeply dipping thrust fault. The amphibolite terrane is composed of amphibolite and metasedimentary rocks in approximately equal amounts accompanied by many bodies of serpentinite and a number of gabbro and dioritic plutons. Most of the amphibolite is foliated, but some is nonfoliated; the nonfoliated amphibolite has an amphibolite mineralogy and commonly a relict volcanic rock texture. The nonfoliated amphibolite occurs on the southern and eastern borders of the amphibolite terrane between the areas offoliated amphibolite and the overly ing metavolcanic and metasedimentary rocks. Hornblende and plagioclase (An30-35) are the characteristic minerals, indicating that the rocks are of the almandine-amphibolite metamorphic facies. The metasedimentary rocks interbedded with the amphibolites include siliceous schist and phyllite, minor quartzite, and subordinate amounts of marble. Potassium-argon age dates obtained on hornblende from foliated amphibolite yield ages of 146?4 and 148? 4 m.y., suggesting a Late Jurassic metamorphic episode. \r\n\r\nMafic and ultramafic rocks are widespread in the amphibolite terrane but are almost entirely absent from the area of greenschist facies metavolcanic and metasedimentary rocks. The ultramafic rocks, predominantly serpentinite, occur as a few large bodies and many small tabular concordant bodies interleaved with the foliated rocks. The ultramafic rocks include harzburgite and d1lIlite and their serpentinized equivalents. In the Condrey Mountain quadrangle, probably more t","language":"ENGLISH","publisher":"U.S. Govt. Print.

Radium ranges from 0.3 to 420 picocuries per liter and has a median value of 8.8, and uranium ranges from 0.02 to 180 micrograms per liter and has a median value of 2.4. Radon concentrations, measured in 32 of the 37 wells, range from less than 100 picocuries per liter to as much as 27,000 and have a median value of 580. Relationships among the radioactive elements and 28 other geochemical parameters were studied by using correlation coefficients and R-mode factor analysis. Five factor groups were determined to represent major influences on water chemistry: (1) short-term solution reactions, (2) oxidation reactions, (3) hydrolysis reactions, (4) uranium distribution, and (5) long-term solution reactions. Uranium concentrations are most strongly influenced by oxidation reactions but also are affected by solution reactions and distribution of uranium in the rocks of the aquifer system. Radon and radium concentrations are mostly controlled by uranium distribution; radium also shows a moderate negative relationship with oxidation. \r\n\r\nTo explain the statistical and spatial relationships among the parameters, a model was developed involving the selective leaching of uranium-bearing phases and metal sulfides which occur in discontinuous zones in sandstone and shale. When reducing conditions prevail, uranium is immobile, but radium can be taken into solution. When faults and associated fractured rocks allow oxidizing conditions to dominate, uranium can be taken into solution; radium can also be taken into solution, or it may become immobilized by coprecipitation with iron and manganese oxides or with barite. Several areas within the study area are discussed in terms of the model.","language":"ENGLISH","publisher":"U.S. Geological Survey,","doi":"10.3133/ofr79974","usgsCitation":"Felmlee, J., and Cadigan, R.A., 1979, Radium and uranium concentrations and associated hydrogeochemistry in ground water in southwestern Pueblo County, Colorado: U.S. Geological Survey Open-File Report 79-974, iv, 54 p. :ill., maps ;28 cm., https://doi.org/10.3133/ofr79974.","productDescription":"iv, 54 p. :ill., maps ;28 cm.","costCenters":[],"links":[{"id":142734,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/1979/0974/report-thumb.jpg"},{"id":36378,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1979/0974/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a80e4b07f02db649aaa","contributors":{"authors":[{"text":"Felmlee, J.

The model, as described, applies specifically to the Skokomish, Nisqually, and Cowlitz Rivers, in Washington State, and more generally to streams in other regions that derive seasonal runoff from melting snow. Thus the techniques demonstrated for these three drainage basins can be used as a guide for applying this method to other streams. Input to the computer program consists of daily averages of gaged runoff of these streams, and daily values of precipitation collected at Longmire, Kid Valley, and Cushman Dam. Predictions are based on estimates of the absolute storage of water, predominately as snow: storage is approximately equal to basin precipitation less observed runoff. A pre-forecast test season is used to revise the storage estimate and improve the prediction accuracy. To obtain maximum prediction accuracy for operational applications with this model , a systematic evaluation of several hydrologic and meteorologic variables is first necessary. Six input options to the computer program that control prediction accuracy are developed and demonstrated. Predictions of streamflow can be made at any time and for any length of season, although accuracy is usually poor for early-season predictions (before December 1) or for short seasons (less than 15 days). The coefficient of prediction (CP), the chief measure of accuracy used in this manual, approaches zero during the late autumn and early winter seasons and reaches a maximum of about 0.85 during the spring snowmelt season.

Most of the presently available studies are based on the assumption that the response of a soil deposit is mainly due to the upward propagation of horizontally polarized shear waves from the underlying bedrock. Equivalent-linear procedures, currently in common use in non-linear soil response analysis, provide a simple approach and have been favorably compared with the actual recorded motions in some particular cases. Strain compatibility in these equivalent-linear approaches is maintained by selecting values of shear moduli and damping ratios in accordance with the average soil strains, in an iterative manner. Truly non-linear constitutive models with complete strain compatibility have also been employed.  The equivalent-linear approaches often raise some doubt as to the reliability of their results concerning the system response in high frequency regions. In these frequency regions the equivalent-linear methods may underestimate the surface motion by as much as a factor of two or more. Although studies are complete in their methods of analysis, they inevitably provide applications pertaining only to a few specific soil systems, and do not lead to general conclusions about soil behavior.  This report attempts to provide a general picture of the soil response through the use of a single-degree-of-freedom non-linear-hysteretic model. Although the investigation is based on a specific type of nonlinearity and a set of dynamic soil properties, the method described does not limit itself to these assumptions and is equally applicable to other types of nonlinearity and soil parameters.","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","doi":"10.3133/ofr79592","collaboration":"In cooperation with the Institute of the Middle East Technical University, Ankara, Turkey","usgsCitation":"Erdik, M.O., 1979, A single-degree-of-freedom model for non-linear soil amplification: U.S. Geological Survey Open-File Report 79-592, i, 35 p.; Tables; Figures, https://doi.org/10.3133/ofr79592.","productDescription":"i, 35 p.; Tables; Figures","onlineOnly":"Y","costCenters":[{"id":237,"text":"Earthquake Science Center","active":true,"usgs":true},{"id":379,"text":"Menlo Park Science Center","active":false,"usgs":true}],"links":[{"id":116760,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/ofr_79_592.gif"},{"id":110892,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/of/1979/0592/","linkFileType":{"id":5,"text":"html"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4b17e4b07f02db6a644b","contributors":{"authors":[{"text":"Erdik, Mustafa Ozder","contributorId":41577,"corporation":false,"usgs":true,"family":"Erdik","given":"Mustafa","email":"","middleInitial":"Ozder","affiliations":[],"preferred":false,"id":158263,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

The earliest finds were made about 125 years ago; essentially no new information has been recorded for a century. \r\n\r\nLarge collections of Anthracopupa from the Dunkard basin sparked inquiry into the land snails from the other two areas. Studies using the SEM (scanning electron microscope) have provided considerable insight into microdetails of shell structure, which allow systematic assignment of these gastropods. All may be assigned to extant families, except one, for which insufficient material allows only superfamily assignment. \r\n\r\nThe prosobranch Dawsonella is confirmed as being a terrestrial neritacean gastropod. To date, it is known only from the upper Middle Pennsylvanian of Illinois and Indiana. All the other Paleozoic land snails are stylommatophoran pulmonates; their current classification as nonmarine cyclophoraceans is not correct. \r\n\r\nRestudy of material from the Joggins section of Nova Scotia indicates that representatives of two ordinal groups of pulmonates appeared simultaneously in upper Lower Pennsylvanian strata; the oldest land prosobranch is found in only very slightly younger rocks. Zonites (Conulus) priscus is reassigned to the new genus Protodiscus in the extant family Discidae. Dendropupa is placed within the family Enidae, Anthraaopupa is placed in the family Tornatellinidae, and 'Pupa' bigsbii is assigned to the superfamily Pupillacea. All four of these family-level taxa are diverse and belong to two orders within the superorder Stylommatophora, heretofore considered a derived rather than an ancestral stock. \r\n\r\nAnthracopupa ohioensis Whitfield is a highly variable species, and two other species Naticopsis (?) diminuta and A.(?) dunkardona, both named by Stauffer and Schroyer, are placed in synonymy with it. To obtain taxonomic data to support the family placement of Anthracopupa, growth forms of modern pupillid and tornatellinid snails have been distinguished. The apertural barriers in Anthracopupa are identical in placement and growth pattern with those of living Tornatellinidae and independently confirm the family placement derived from study of the general form. One new species, A. sturgeoni, has been named. \r\n\r\nAnthracopupa is found most commonly in thin limestones interpreted as having been deposited in pools into which the small shells floated. Dendropupa is most commonly found in erect tree stumps that were covered by rapid sedimentation. Both environments are similar to those in which the shells of allied living species may be found today, and the fossils support environmental interpretations made entirely from lithology. \r\n\r\nA survey of the few European occurrences of Paleozoic land snails indicates that both Anthracopupa and Dendropupa occur in Lower Permian strata; Anthracopupa is known from beds as old as Westphalian B. These genera cannot be used for determining the Carboniferous-Permian boundary. Both the long local stratigraphic range of A. brittanica and D. vetusta reported in the literature and the moderately long range and great variability of A. ohioensis suggest that the land snails have little stratigraphic utility. \r\n\r\nOn the other hand, the occurrence of these land snails in the late Paleozoic of the Northern Hemisphere provides further fossil evidence suggestive of a closed Atlantic Ocean at that time. A comparison of the Paleozoic and the present distributions of land -snail families on both sides of the Atlantic provides some interesting data on geographic shifts of organisms. Finally, the assignment of the earliest land snails to extant taxa at the family level indicates that the subclass Pulmonata has been very conservative in its evolution after initial radiation. \r\n\r\nA few notes on Paleozoic freshwater snails complete this survey.","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/pp1072","usgsCitation":"Solem, A., and Yochelson, E.L., 1979, North American Paleozoic land snails, with a summary of other Paleozoic nonmarine snails: U.S. Geological Survey Professional Paper 1072, 42 p., https://doi.org/10.3133/pp1072.","productDescription":"42 p.","costCenters":[],"links":[{"id":33840,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/pp/1072/report.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":125082,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/pp/1072/report-thumb.jpg"},{"id":395507,"rank":3,"type":{"id":36,"text":"NGMDB Index Page"},"url":"https://ngmdb.usgs.gov/Prodesc/proddesc_93001.htm"}],"country":"United States","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -87.71484375,\n              41.04621681452063\n            ],\n            [\n              -67.1484375,\n              41.04621681452063\n            ],\n            [\n              -67.1484375,\n              45.706179285330855\n            ],\n            [\n              -87.71484375,\n              45.706179285330855\n            ],\n            [\n              -87.71484375,\n              41.04621681452063\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4afde4b07f02db696e90","contributors":{"authors":[{"text":"Solem, Alan","contributorId":38985,"corporation":false,"usgs":true,"family":"Solem","given":"Alan","email":"","affiliations":[],"preferred":false,"id":152709,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Yochelson, Ellis Leon","contributorId":66678,"corporation":false,"usgs":true,"family":"Yochelson","given":"Ellis","email":"","middleInitial":"Leon","affiliations":[],"preferred":false,"id":152710,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

The sand that forms the dunes is massive and intensely burrowed in the upper part; traces of horizontal or slightly inclined bedding appear near the base. Quartz is the dominant mineral constituent of the sand. Microline is abundant in the very fine to fine sand fraction. The heavy-mineral assemblages (high zircon, tourmaline, rutile) are more mature than in most of the possible source rocks. The most abundant minerals in the clay-sized fraction are dioctahedral vermiculite, kaolinite, illite, montmorillonite, and gibbsite. The first four minerals are common in deposits of late Wisconsin and Holocene age. The gibbsite may be detrital, coming from weathered rocks of Tertiary age. The soil profile in the dune sand is weakly to moderately developed. At or near the base of the Parsonsburg Sand are peaty beds that range in age from about 30,000 to about 13,000 radiocarbon years B.P. Microfloral assemblages in the peaty beds suggest that the dunes on the uplands formed in a spruce parkland during the late Wisconsin glacial maximum. The river dunes may also be of late Wisconsin age, but could be Holocene.","language":"ENGLISH","publisher":"U.S. Govt.

Mineralogic analysis of the total sulfides contained in the drill core shows only slight changes in the total sulfide content among the three geochemical regimes. However, induced polarization measurements on the core samples indicate that samples obtained from the reduced side of the ore zone are more electrically polarizable than those from the oxidized side of the ore zone, and therefore probably contain more pyrite. Analysis of the clay-size fraction in core samples indicates that montmorillonite is the dominant clay mineral. High resistivity values within the ore zone indicate the presence of calcite cement concentrations that are higher than those seen outside of the ore zone. Between-hole resistivity and induced polarization measurements show the presence of an extensive zone of calcite cement within the ore zone, and electrical polarizable material (such as pyrite) within and on the reduced side of the ore zone. A quantitative analysis of the between-hole resistivity data, using a layered-earth model, and a qualitative analysis of the between-hole induced polarization measurements showed that mineralogic variations among the three geochemical environments were more pronounced than were indicated by the geophysical and geologic well logs.\r\n\r\nUranium exploration in the South Texas Coastal Plain area has focused chiefly in three geologic units: the Oakville Sandstone, the Catahoula Tuff, and the Jackson Group. The Oakville Sandstone and the Catahoula Tuff are of Miocene age, and the Jackson Group is of Eocene age (Eargle and others, 1971). Most of the uranium mineralization in these formations is low grade (often less than 0.02 percent U3O8) and occurs in shallow deposits that are found by concentrated exploratory drilling programs. The sporadic occurrence of these deposits makes it desirable to develop borehole geophysical techniques that will help to define the depositional environments of the uranium ore, which is characterized by geochemical changes near the uranium deposits. Geochemical changes are accompanied by changes in the physical characteristics of the rocks that can be detected with borehole geophysical tools. \r\n\r\nThis study is concerned with a uranium deposit within the Jackson Group that is located just east of Karnes City, Tex. Five holes were drilled on this property to obtain borehole geophysical data and cores. The cores were analyzed for mineralogic and electrical properties. The borehole geophysical information at this property included induced polarization, resistivity, gamma-gamma density, neutron-neutron, gamma-ray, caliper, and single-point-resistance logs. Between-hole resistivity and induced polarization measurements were made between hole pairs across the ore deposit and off the ore deposit.","language":"ENGLISH","publisher":"U.S. Geological Survey,","doi":"10.3133/ofr79585","usgsCitation":"Daniels, J.J., Scott, J.H., and Smith, B.D., 1979, Analysis of borehole geophysical information across a uranium deposit in the Jackson Group, Karnes County, Texas: U.S. Geological Survey Open-File Report 79-585, 32 p. :ill. ;27 cm., https://doi.org/10.3133/ofr79585.","productDescription":"32 p. :ill. ;27 cm.","costCenters":[],"links":[{"id":141984,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/1979/0585/report-thumb.jpg"},{"id":36080,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1979/0585/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4acfe4b07f02db6806a5","contributors":{"authors":[{"text":"Daniels, Jeffrey J.","contributorId":87938,"corporation":false,"usgs":true,"family":"Daniels","given":"Jeffrey","email":"","middleInitial":"J.","affiliations":[],"preferred":false,"id":157833,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Scott, James Henry","contributorId":60211,"corporation":false,"usgs":true,"family":"Scott","given":"James","email":"","middleInitial":"Henry","affiliations":[],"preferred":false,"id":157832,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Smith, Bruce D. 0000-0002-1643-2997 bsmith@usgs.gov","orcid":"https://orcid.org/0000-0002-1643-2997","contributorId":845,"corporation":false,"usgs":true,"family":"Smith","given":"Bruce","email":"bsmith@usgs.gov","middleInitial":"D.","affiliations":[{"id":211,"text":"Crustal Geophysics and Geochemistry Science Center","active":true,"usgs":true}],"preferred":true,"id":157831,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}
