Most recorded production from lode deposits is credited to mines in the Gold Basin district, which is in the southern White Hills, whereas the bulk of the placer production has been from placers worked along the eastern flank of the Lost Basin range, about 16 km to the northeast across Hualapai Valley. Gold in quartz veins apparently was first discovered in the 1870's. Recorded production from the districts between 1901 and 1942 includes 13,508 oz gold and 6,857 oz silver, and this recorded production has a dollar value of about $359,000 of which 98 percent is credited to gold.</p><p>Most known occurrences of lode gold in the districts are associated with widespread quartz-cored pegmatite-vein systems, presumably emplaced episodically during Proterozoic X, Proterozoic Y, and Late Cretaceous time into Proterozoic X metamorphic and igneous rocks. The bulk of the veins apparently were emplaced during the Late Cretaceous, and they were localized along both high- and low-angle structures in the Proterozoic X terrane. These veins appear to be associated genetically with presumably Late Cretaceous, two-mica magmatism. A Late Cretaceous two-mica monzogranite crops out in an approximately 4 to 5 km<sup>2</sup> area in the southern part of the Gold Basin district and includes some facies of episyenite. Some gold is found also in small episyenitic alteration pipes, or in veins caught up tectonically along a regionally extensive, low-angle detachment surface which crops out prominently in the southern White Hills, and has been traced for at least 30 km along the western flank of the White Hills.</p><p>Hydrothermal micas from selected veins in the districts give K-Ar ages of 822, 712, 69, 68, and 65 m.y. (million years), and from the pipes, ages of 130 and 127 m.y. The oldest ages (822 and 712 m.y.) presumably reflect resetting of veins that probably were emplaced penecontemporaneous with emplacement of the 1,400-m.y. granite of Gold Butte, which crops out just to the north of Lake Mead. The latter ages (130 and 127 m.y.) must reflect either the presence of excess radiogenic argon in the hydrothermal environment of the evolving pipes, or contamination of the dated mineral separates by Proterozoic mica and (or) feldspar. Primary white mica from the two-mica monzogranite gives a K-Ar age of 72 m.y..</p><p>Most occurrences of gold in the veins and pipes probably reflect either remobilization of gold from gold-bearing, near-surface Proterozoic source areas, or anatectic incorporation of gold into Late Cretaceous, two-mica magmas from very deep gold-bearing Proterozoic sources. Deposition of gold occurred in a mesothermal environment during the galena-, chalcopyrite-, ferroan-carbonate-bearing stages of the veins. Homogenization studies of fluid inclusions prominent in the veins and pipes yield temperatures mostly in the range 150 to 280°C. Early-stage, trapping temperatures at the pipes probably were about 330°C and pressures in the range 500 to 700 bars can be inferred. Fluids were moderately saline, mostly 4 to 16 weight percent NaC1 equivalent, nonboiling, and also contain appreciable amounts of carbon dioxide and, in places, fluorine. Such fluids associated with the deposition of gold in these districts largely bridge the fluid composition interval between many other epithermal precious-metal and porphyry coper deposits.</p><p>Approximately 350 compositional analyses obtained from native-gold samples from 20 mines in the Gold Basin district and 48 veins in the Lost Basin district show silver contents that range from 6 to approximately 50 weight percent, and copper from 0.01 to 0.5 weight percent. Metal zonation and possible relation to a porphyry copper system at depth can be inferred from some of these chemical data. The differences in the composition of placer gold from 24 occurrences in the Lost Basin district from that of nearby lode sources suggest that other sources contributed gold to the placers or that locally derived grains were enriched by oxidation and weathering of the lodes.<br></p>","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/ofr821052","usgsCitation":"Theodore,

Underlying the site in descending order are: (1) low permeability glacial till, (2) a moderately permeable fractured rock aquifer--the Lockport Dolomite, and (3) a low permeability unit--the Rochester Shale. The site is bounded on three sides by ground-water drains; the Niagara River Gorge, the Niagara Power Project canal, and the power project conduits. \r\n\r\nA finite element model was used to simulate ground-water flow along an east-west section through the Hyde Park site (from the power project conduits to the Niagara Gorge). Steady-state conditions were simulated with an average annual recharge rate of 5 inches per year. The calibrated model simulated measured water levels within 5 feet in the glacial till and upper unit of the Lockport Dolomite and approximated the configuration of the water table. \r\n\r\nBased on simulation, ground-water flow near the Hyde Park site can be summarized as follows: \r\n\r\n1. Specific discharge (Darcy velocity) ranges from about 0.01 to 0.1 foot per day in the upper unit of the Lockport Dolomite to less than 0.00001 foot per day in the Rochester Shale. Real velocities are highest in the upper unit of the Lockport, ranging from about 1.5 to 4.8 feet per day. \r\n\r\n2. A ground-water divide exists east of the landfill, indicating that all ground water originating near or flowing beneath the landfill will flow toward and discharge in the gorge. \r\n\r\n3. The zone of highest velocities (and presumably greatest potential for transporting chemical contaminants) includes the upper unit of the Lockport and part of the lower unit of the Lockport Dolomite between the landfill and the gorge. The time required for ground water to move from the landfill to the gorge in the Lockport Dolomite is estimated to be 5 to 7 years.","language":"ENGLISH","publisher":"U.S. Geological Survey,","doi":"10.3133/ofr82159","usgsCitation":"Maslia, M., and Johnston, R., 1982, Simulation of ground-water flow in the vicinity of Hyde Park landfill, Niagara Falls, New York: U.S. Geological Survey Open-File Report 82-159, v, 19 p., 5 over-size sheets, ill., (some folded) ;28 cm., https://doi.org/10.3133/ofr82159.","productDescription":"v, 19 p., 5 over-size sheets, ill., (some folded) ;28 cm.","costCenters":[],"links":[{"id":151328,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/1982/0159/report-thumb.jpg"},{"id":49519,"rank":400,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/1982/0159/plate-1.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":49520,"rank":401,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/1982/0159/plate-2.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":49521,"rank":402,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/1982/0159/plate-3.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":49522,"rank":403,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/1982/0159/plate-4.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":49523,"rank":404,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/1982/0159/plate-5.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":49524,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1982/0159/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e49f7e4b07f02db5f24ff","contributors":{"authors":[{"text":"Maslia, M.L.","contributorId":24090,"corporation":false,"usgs":true,"family":"Maslia","given":"M.L.","affiliations":[],"preferred":false,"id":181870,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Johnston, R.H.","contributorId":19536,"corporation":false,"usgs":true,"family":"Johnston","given":"R.H.","email":"","affiliations":[],"preferred":false,"id":181869,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

The range of exponents of simple power-function relations is large, both between different reaches of the river, and among different sections within a given reach. The at-a-station exponents plot in several fields of the b-f-m diagram, suggesting that morphologic and hydraulic changes with increasing discharge vary considerably. Systematic changes in the plotting positions of the exponents with time indicate that in general, the width exponent has decreased, although trends are not readily apparent in the other exponents. Plots of the hydraulic-geometry relations indicate that simple power functions are not the proper model in all instances. For these sections, breaks in the slopes of the hydraulic geometry relations serve to partition the data sets. Power functions fit separately to the partitioned data described the width-, depth-, and velocity-discharge relations more accurately than did a single power function. Plotting positions of the exponents from hydraulic geometry relations of partitioned data sets on b-f-m diagrams indicate that much of the apparent variations of plotting positions of single power functions results because the single power functions compromise both subsets of partitioned data. For several sections, the shape of the channel primarily accounts for the better fit of two-power functions to partitioned data than a single power function over the entire range of data. These non-log linear relations may have significance for channel maintenance.

The method is typically applied to estimate terrain effects for topography near the station, for example within 3 km of the station, although it has been used successfully to a radius of 15 km to estimate corrections in areas where topographic mapping is poor. \r\n\r\nPoints (about 20) that define topographic maxima, minima, and changes in the slope gradient are picked on the topographic map, within the desired radius of correction about the station. Particular attention must be paid to the area immediately surrounding the station to ensure a good topographic representation. The horizontal and vertical coordinates of these points are entered into the computer, usually by means of a digitizer. The computer then fits a multiquadric surface to the input points to form an analytic representation of the surface. By means of the divergence theorem, the gravity effect of an interior closed solid can be expressed as a surface integral, and the terrain correction is calculated by numerical evaluation of the integral over the surfaces of a cylinder, The vertical sides of which are at the correction radius about the station, the flat bottom surface at the topographic minimum, and the upper surface given by the multiquadric equation. \r\n\r\nThe method has been tested with favorable results against models for which an exact result is available and against manually computed field-station locations in areas of rugged topography. By increasing the number of points defining the topographic surface, any desired degree of accuracy can be obtained.

Broad continental uplift associated with Red Sea rifting is symmetric about the Red Sea axis, and geologic and geochronologic evidence indicate that uplift has occurred mainly in the interval 25-13 Ma (mega-annum) ago. Thermal-profile changes in the upper mantle resulting from an influx of hot material associated with rifting yield the correct order of magnitude of uplift, and this mechanism is suggested as the explanation for the regional doming. A lithospheric section, constructed from seismic refraction, gravity, and regional geologic data, provides the framework for construction of thermal models. \r\n\r\nThermal gradient measurements were made in drill holes at five shot points. Geotherms for the Shield, which assume a radiogenic heat-source distribution that decreases exponentially with depth, yield temperatures of about 450?C at a depth of 40 km (base of the crust) for shot points 2 (Sabhah) and 3. The geotherm for shot point 4 (near Bishah) yields a distinctly higher temperature (about 580?C) for the same depth. \r\n\r\nStatic models used to model the heat flow in the oceanic crust of the Red Sea shelf and coastal plain either yield too small a heat flow to match the observed heat flow or give lithosphere thicknesses that are so thin as to be improbable. Dynamic (solid-state accretion) models, which account for mantle flow at the base of the lithosphere, adequately match the observed heat-flow values. In the deep-water trough of the Red Sea, which is presently undergoing active sea-floor spreading, classical models of heat flow for a moving slab with accretion at the spreading center are adequate to explain the average heat-flow level. \r\n\r\nAt shot point 5 (Ad Darb), the anomalous heat flow of 2 HFU (heat-flow units) can be explained in terms of a Shield component (0.8-1.0 HFU) and a component related to heating by the abutting oceanic crust a few kilometers away for periods exceeding 10 Ma. Analytical results are included for: 1) the cooling of a static sheet with an initial temperature distribution characteristic of a moving slab in a sea-floor spreading environment, and 2) the heating of a homogeneous quarter-space at its vertical boundary.","language":"ENGLISH","publisher":"U.S. Geological Survey,","doi":"10.3133/ofr82794","usgsCitation":"Gettings, M.E., 1982, Heat-flow measurements at shot points along the 1978 Saudi Arabia seismic deep-refraction line; Part II, Discussion and interpretation: U.S. Geological Survey Open-File Report 82-794, ii, 43 p., ill. ;28 cm., https://doi.org/10.3133/ofr82794.","productDescription":"ii, 43 p., ill. ;28 cm.","costCenters":[],"links":[{"id":141604,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/1982/0794/report-thumb.jpg"},{"id":36728,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1982/0794/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a69e4b07f02db63c67f","contributors":{"authors":[{"text":"Gettings, M.

Because of the pattern drilling at each shot point, several holes (60 m deep) could be logged for temperature at each site and thus allow a better estimate of the geothermal gradient. Each site was mapped and sampled in detail, and modal and. chemical analyses of representative specimens were made in the laboratory. Thermal conductivities were computed from the modal analyses and single-mineral conductivity data. \r\n\r\nThe resulting heat-flow values, combined with published values for the Red Sea and coastal plain, indicate a three-level pattern, with a heat flow of about 4.5 heat-flow unit (HFU) over the Red Sea axial trough, about 3.0 HFU over the shelf and coastal plain, and an essentially constant 1.0 HFU over the Arabian Shield at points well away from the suture zone with the oceanic crust. At three sites where the rocks are granitic, gamma-ray spectrometry techniques were employed to estimate thorium, potassium, and uranium concentrations. The resulting plot of heat generation versus heat flow suggests that in the Arabian Shield the relationship between heat flow and heat production is not linear. More heat-flow data are essential to establish or reject this conclusion.","language":"ENGLISH","publisher":"U.S. Geological Survey,","doi":"10.3133/ofr82793","usgsCitation":"Gettings, M.E., and Showail, A., 1982, Heat-flow measurements at shot points along the 1978 Saudi Arabia seismic deep-refraction line; Part I, Results of the measurements: U.S. Geological Survey Open-File Report 82-793, iii, 102 p., ill., maps ;28 cm., https://doi.org/10.3133/ofr82793.","productDescription":"iii, 102 p., ill., maps ;28 cm.","costCenters":[],"links":[{"id":141929,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/1982/0793/report-thumb.jpg"},{"id":36727,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1982/0793/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a69e4b07f02db63c289","contributors":{"authors":[{"text":"Gettings, M.

Correlation analysis and R-mode factor analysis indicate that three major factors affect water composition in the spring systems studied: (1) duration of water circulation, (2) depth of water circulation, and (3) partial pressure of carbon dioxide. An examination of factor scores indicates that several types of hydrogeologic systems were sampled. Most of the samples are (1) older water from deeper circulating systems having relatively high salinity, high temperature, and low Eh or (2) younger water from shallower circulating systems having relatively low salinity, low temperature, and high Eh. The rest of the samples are from more complex systems. Any of the systems can have a relatively high or low content of dissolved carbonate species, resulting in a low or high pH, respectively. Uranium concentrations are commonly higher in waters of relatively low temperature and high Eh, and radium concentrations are commonly higher in waters having a relatively high carbonate content (low pH) and, secondarily, relatively high salinity. \r\n\r\nWater samples were collected and (or) measurements were taken at 156 of the 171 mineral-spring sites visited. Various samples were analyzed for radium, uranium, radon, helium, and radium-228 as well as major ions and numerous trace elements. On-site measurements for physical properties including temperature, specific conductance, pH, Eh, and dissolved oxygen were made. All constituents and properties show a wide range of values. Radium concentrations range from less than 0.01 to 300 picocuries per liter; they average 1.48 picocuries per liter and have an anomaly threshold value of 171 picocuries per liter for the samples studied. Uranium concentrations range from less than 0.01 to 120 micrograms per liter and average 0.26 micrograms per liter; they have an anomaly threshold value of 48.1 micrograms per liter. Radon content ranges from less than 10 to 110,000 picocuries per liter, averages 549 picocuries per liter and has an anomaly threshold of 20,400 picocuries per liter. Helium content ranges from -1,300 to +13,000 parts per billion relative to atmospheric helium; it averages +725 parts per billion and has an anomaly threshold of 10,000 parts per billion. Radium-228 concentrations range from less than 2.0 to 33 picocuries per liter; no anomaly threshold was determined owing to the small number of samples. All of the anomaly thresholds may be somewhat high because the sampling was biased toward springs likely to be radioactive. \r\n\r\nThe statistical variance in radium and uranium concentrations unaccounted for by the identified factors testifies to the complexity of some hydrogeologic systems. Unidentified factors related to geologic setting and the presence of uranium-rich rocks in the systems also affect the observed concentrations of the radioactive elements in the water. The association of anomalous radioactivity in several springs with nearby known uranium occurrences indicates that other springs having anomalous radioactivity may also be associated with uranium occurrences as yet undiscovered.","language":"ENGLISH","publisher":"U.S. Geological Survey,","doi":"10.3133/ofr82324","usgsCitation":"Felmlee, J., and Cadigan, R.A., 1982, Radioactivity and geochemistry of selected mineral-spring waters in the Western United States; basic data and multivariate statistical analysis: U.S. Geological Survey Open-File Report 82-324, ii, 107 p. :ill., maps ;28 cm., https://doi.org/10.3133/ofr82324.","productDescription":"ii, 107 p. :ill., maps ;28 cm.","costCenters":[],"links":[{"id":142733,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/1982/0324/report-thumb.jpg"},{"id":36377,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1982/0324/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a60e4b07f02db634cbd","contributors":{"authors":[{"text":"Felmlee, J.K.","contributorId":106114,"corporation":false,"usgs":true,"family":"Felmlee","given":"J.K.","email":"","affiliations":[],"preferred":false,"id":158341,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Cadigan, R.

The orebody, which contains abundant amorphous organic material, is situated on the reduced side of a regional reduction-oxidation (redox) interface. The presence of amorphous organic material suggests the orebody may represent a tabular (primary) deposit, whereas the close proximity of the orebody to the redox interface is suggestive that uranium was secondarily redistributed by oxidative processes from pre-existing tabular orebodies. Uranium contents correlate positively with both organic carbon and vanadium contents. Petrographic evidence and scanning electron microscope-energy dispersive analyses point to uranium residence in the epigentically introduced amorphous organic material, which coats detrital grains and fills voids. Uranium mineralization was preceded by the following diagenetic alterations: precipitation of pyrite (ẟ<sup>34</sup>S values ranging from-11.0 to-38.2 per mil); precipitation of mixed-layer smectite-illite clays; partial dissolution of some of the detrital feldspar population; and precipitation of quartz and adularia overgrowths. Alterations associated with uranium mineralization include emplacement of amorphous organic material (possibly uranium bearing); destruction of detrital iron-titanium oxide grains; coprecipitation of chlorite and microcrystalline quartz, and precipitation of pyrite and marcasite (ẟ<sup>34</sup>S values for these sulfides ranging from -29.4 to -41.6 per mil). After mineralization, calcite, dolomite, barite, and kaolinite precipitated, and authigenic iron disulfides were replaced by ferric oxides and hydroxides. Geochemical data (primarily the positive correlation of uranium content to both organic carbon and vanadium contents) and petrographic observations (epigentically introduced amorphous organic matter and uranium residence in this organic matter) indicate that the Mariano Lake orebody is a tabular-type uranium deposit. Oxidative processes have not noticeably redistributed and reconcentrated primary uranium in the immediate vicinity of the deposit nor have they greatly modified geochemical characteristics in the ore. Preservation of the Mariano Lake deposit may not only be related to its position along the synclinal trough, where oxidative destruction of the orebody has been inhibited by stagnation of oxidizing ground waters by the structure, but also due to the deflection of ground waters (resulting from low orebody porosity) around the orebody.</p>","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/ofr82888","usgsCitation":"Fishman, N.S., and Reynolds, R.L., 1982, Origin of the Mariano Lake uranium deposit, McKinley County, New Mexico: U.S. Geological Survey Open-File Report 82-888, iii, 52 p., https://doi.org/10.3133/ofr82888.","productDescription":"iii, 52 p.","costCenters":[{"id":318,"text":"Geosciences and Environmental Change Science Center","active":true,"usgs":true}],"links":[{"id":141608,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/1982/0888/report-thumb.jpg"},{"id":36405,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1982/0888/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"country":"United States","state":"New Mexico","county":"McKinley County","geographicExtents":"{\"type\":\"FeatureCollection\",\"features\":[{\"type\":\"Feature\",\"geometry\":{\"type\":\"Polygon\",\"coordinates\":[[[-109.0452,36.006],[-108.7687,36.0063],[-108.3738,36.0044],[-108.2646,36.0038],[-108.1559,36.0027],[-108.1468,36.0028],[-108.1411,36.0029],[-108.1224,36.0028],[-107.8738,36.0034],[-107.8351,36.0035],[-107.6776,36.0031],[-107.66,36.0034],[-107.6423,36.0032],[-107.6247,36.0034],[-107.6213,36.003],[-107.6042,36.0032],[-107.5866,36.003],[-107.5718,36.0027],[-107.5541,36.0025],[-107.5513,36.0026],[-107.5161,36.0026],[-107.4421,36.0008],[-107.4068,36.0007],[-107.3875,36.0009],[-107.3397,36.0006],[-107.317,36.0008],[-107.3056,36.0005],[-107.3054,35.991],[-107.3058,35.9765],[-107.3055,35.9311],[-107.3051,35.8744],[-107.3049,35.8295],[-107.3047,35.8168],[-107.3053,35.7864],[-107.3054,35.7573],[-107.3057,35.7419],[-107.3049,35.7301],[-107.3052,35.7151],[-107.305,35.6997],[-107.3053,35.6852],[-107.305,35.6707],[-107.3048,35.6552],[-107.3046,35.6439],[-107.3041,35.6139],[-107.3032,35.5277],[-107.3035,35.4787],[-107.3025,35.4247],[-107.3016,35.3021],[-107.518,35.3036],[-107.5231,35.3036],[-107.6183,35.3059],[-107.6229,35.3059],[-107.6231,35.3159],[-107.6243,35.3485],[-107.7287,35.3489],[-107.7295,35.3366],[-107.7288,35.3062],[-107.7812,35.3063],[-107.8111,35.3063],[-107.8297,35.3065],[-107.8336,35.3064],[-107.9159,35.3065],[-107.9351,35.3066],[-107.9396,35.3065],[-107.974,35.3064],[-107.992,35.3066],[-108.0473,35.307],[-108.143,35.3057],[-108.151,35.307],[-108.2558,35.3077],[-108.364,35.3065],[-108.4661,35.3081],[-108.4644,35.2214],[-108.4659,35.1623],[-108.4661,35.1355],[-108.4673,35.0501],[-108.4678,34.9597],[-108.497,34.96],[-108.52,34.96],[-108.7809,34.9595],[-109.0458,34.9611],[-109.0458,35.166],[-109.0457,35.1796],[-109.0457,35.1941],[-109.0457,35.2078],[-109.0457,35.2228],[-109.0457,35.2359],[-109.0456,35.3531],[-109.0457,35.6637],[-109.0452,36.006]]]},\"properties\":{\"name\":\"McKinley\",\"state\":\"NM\"}}]}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a61e4b07f02db635e15","contributors":{"authors":[{"text":"Fishman, Neil S.","contributorId":106464,"corporation":false,"usgs":true,"family":"Fishman","given":"Neil","email":"","middleInitial":"S.","affiliations":[],"preferred":false,"id":158404,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Reynolds, Richard L. 0000-0002-4572-2942 rreynolds@usgs.gov","orcid":"https://orcid.org/0000-0002-4572-2942","contributorId":139068,"corporation":false,"usgs":true,"family":"Reynolds","given":"Richard","email":"rreynolds@usgs.gov","middleInitial":"L.","affiliations":[{"id":318,"text":"Geosciences and Environmental Change Science Center","active":true,"usgs":true}],"preferred":true,"id":158403,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

Information on hydraulic properties of the basin fill, recharge from bordering mountain ranges, discharge by evapotranspiration, and exchange of water between aquifer and stream was available from previous measurements or estimates. The steady-state calibration procedure and subsequent transient simulations demonstrated that the original conceptualization can be reasonably simulated. An analysis of model sensitivity to increases and decreases in certain hydraulic properties indicated a low sensitivity to aquifer anisotropy and a low to moderate sensitivity to stream leakance and evapotranspiration rate. An analysis to investigate the effects of generalizing aquifer conductivity and recharge showed that flow components and water-level response to stress could be simulated adequately but that steady-state water-level conditions could not. During equilibrium conditions, recharge to and discharge from the basin was about 16,500 acre-feet per year. Modeling results indicated that by 1978 the storage depletion rate had reached 5,600 acre-feet per year resulting from a ground-water withdrawal rate of 10,500 acre-feet per year.

In connection with the proposed reservoirs, the U.S. Geological Survey was requested to define the existing ground-water conditions in the shallow ground-water system of the area and to project the post-construction effects of the reservoirs on the shallow aquifer, especially in relation to aquifer-head changes but also with respect to possible changes in the chemical quality of the ground water.</p>\n<p>The Corps of Engineers' plan includes a total impoundment reservoir (Kiowa Peak Lake on North Croton Creek) with more than 170,000 acre-feet of storage at the 100-year average pool altitude of 1,550 feet. Croton Lake (23,000 acrefeet of storage at the 100-year average pool altitude of 1,760 feet) on Croton Creek and Dove Lake (no permanent storage) on Salt Croton Creek are projected to hold salt water for transfer to the large Kiowa Peak Lake.</p>\n<p>The aquifer in the project area is a shallow water-table system with relatively fresh water (calcium sulfate type), in comparison to the saline streamflow, and contains 2,000 to 5,000 milligrams per liter of dissolved solids. The aquifer consists of Permian rocks with very small permeability and is separated from an even less perneable and deeper brine system (sodium chloride type of up to 200,000 milligrams per liter of dissolved solids) by a thin transition zone. Small quantities of infiltration from precipitation in the drainage area constitute the recharge to the aquifer. Discharge from the aquifer consists of the base flow along creeks; well discharge is negligible.</p>\n<p>Two-dimensional digital-computer models were developed for aquifer simulation of steady and transient conditions in which the density effects of salt water are considered. The models were used to project the effects of the 100- year impoundment of salt water in Kiowa Peak Lake and Croton Lake on the freshwater system. Rises in aquifer head of 10 to 50 feet are projected only for areas near each dan and along each lake shoreline. The maximum migration of salt water downstream from each dam is projected to be about 1 mile. The modeling efforts in this study did not include the effects of hydrodynamic dispersion nor consideration of possible changes in the hydraulic conductivity of the aquifer due to physical and chemical interactions in the salt-water and fresh-water environments.</p>","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Austin, TX","doi":"10.3133/ofr82908","isbn":"pbk","usgsCitation":"Garza, S., 1982, Projected effects of proposed salinity-control projects on shallow ground water; preliminary results for the upper Brazos River basin, Texas: U.S. Geological Survey Open-File Report 82-908, Report: vi, 47 p.; 6 Plates, https://doi.org/10.3133/ofr82908.","productDescription":"Report: vi, 47 p.; 6 Plates","onlineOnly":"N","additionalOnlineFiles":"N","costCenters":[{"id":583,"text":"Texas Water Science Center","active":true,"usgs":true}],"links":[{"id":36613,"rank":400,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/1982/0908/plate-1.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":36614,"rank":401,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/1982/0908/plate-2.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":36615,"rank":402,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/1982/0908/plate-3.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":142384,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/1982/0908/report-thumb.jpg"},{"id":36616,"rank":403,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/1982/0908/plate-4.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":36617,"rank":404,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/1982/0908/plate-5.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":36618,"rank":405,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/1982/0908/plate-6.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":36619,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1982/0908/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a9ae4b07f02db65d9d7","contributors":{"authors":[{"text":"Garza, Sergio","contributorId":88713,"corporation":false,"usgs":true,"family":"Garza","given":"Sergio","email":"","affiliations":[],"preferred":false,"id":158649,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

The study area consists of approximately the southern one-half of the 1? by 3? Nabesna quadrangle in east-central Alaska. The digital geologic data base consists of data compiled under the Alaskan Mineral Resource Assessment Program (AMRAP) as well as digital elevation data and Landsat spectral reflectance data from the Multispectral Scanner System. The digital data base used to develop and implement a conceptual model for porphyry-type copper mineralization consisted of 16 original data types and 18 derived data sets formatted in a grid-cell (raster) structure and registered to a map base in the Universal Transverse Mercator (UTM) projection. Minimum curvature and inverse distance squared interpolation techniques were used to generate continuous surfaces from sets of irregularly spaced data points. Processing requirements included: (1) merging or overlaying of data sets, (2) display and color coding of maps and images, (3) univariate and multivariate statistical analyses, and (4) compound overlaying operations. Data sets were merged and processed to create stereoscopic displays of continuous surfaces. The ratio of several data sets were calculated to evaluate relative variations and to enhance the display of surface alteration (gossans). Factor analysis and principal components analysis techniques were used to determine complex relationships and correlations between data sets. The resultant model consists of 10 parameters that identify three areas most likely to contain porphyry copper mineralization; two of these areas are known occurrences of mineralization and the third is not well known. Field studies confirmed that the three areas identified by the model have significant copper potential.","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/ofr82801","usgsCitation":"Trautwein, C.M., Greenlee, D.D., and Orr, D.G., 1982, Digital data base application to porphyry copper mineralization in Alaska; case study summary: U.S. Geological Survey Open-File Report 82-801, iii, 17 p., https://doi.org/10.3133/ofr82801.","productDescription":"iii, 17 p.","costCenters":[{"id":222,"text":"Earth Resources Observation and Science (EROS) Center","active":true,"usgs":true}],"links":[{"id":145094,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/1982/0801/report-thumb.jpg"},{"id":39332,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1982/0801/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4b32e4b07f02db6b4653","contributors":{"authors":[{"text":"Trautwein, Charles M. trautwein@usgs.gov","contributorId":2861,"corporation":false,"usgs":true,"family":"Trautwein","given":"Charles","email":"trautwein@usgs.gov","middleInitial":"M.","affiliations":[],"preferred":true,"id":163183,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Greenlee, David D.","contributorId":59802,"corporation":false,"usgs":true,"family":"Greenlee","given":"David","email":"","middleInitial":"D.","affiliations":[],"preferred":false,"id":163185,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Orr, Donald G.","contributorId":6454,"corporation":false,"usgs":true,"family":"Orr","given":"Donald","email":"","middleInitial":"G.","affiliations":[],"preferred":false,"id":163184,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

The study evaluated present knowledge and concepts of the ground-water system and the ability of the model to represent the system. Modeling assumptions and generalized physical parameters that were used may have transfer value in the construction and calibration of models of other basins along the lower Colorado River. The aquifer was simulated in two layers to represent the three-dimensional system. Ground-water conditions were simulated for 1940-41, the mid-1960's, and 1980. Overall model results generally compared favorably with available field information. The model results showed that for 1940-41 the Colorado River was a losing stream through out Parker Valley. Infiltration of surface water from the river was the major source of recharge. The dominant mechanism of discharge was evapotranspiration by phreatophytes. Agricultural development between 1941 and the mid-1960 's resulted in significant changes to the ground-water system. Model results for conditions in the mid-1960 's showed that the Colorado River had become a gaining stream in the northern part of the valley as a result of higher water levels. The rise in water levels was caused by infiltration of applied irrigation water. Diminished water-level gradients from the river in the rest of the valley reduced the amount of infiltration of surface water from the river. Models results for conditions in 1980 showed that ground-water level rises of several feet caused further reduction in the amount of surface-water infiltration from the river.

Anomalous concentrations of mostly lithophile elements, particularly niobium, beryllium, lead, yttrium, tin, zinc, manganese, and molybdenum in the magnetic and nonmagnetic fraction of heavy-mineral concentrates derived from stream sediment suggest that late stage, highly differentiated felsic rocks were involved in the eruptive history of the Mount Belknap caldera. Q-mode factor analysis was used to characterize the geochemical assemblages within the survey area, and the areal distribution of high-factor scores associated with mineralization indicates favorable target areas for future exploration.

A finite-element network was designed to represent the topography and vegetative cover of the study reach. Hydrographic data collected for the 1980 flood were used to calibrate the flow model. The finite-element network was then modified to represent conditions prior to roadway construction, and the hydraulic impact of I-10 was determined by comparing ' before ' and ' after ' results. Upstream from the roadway, maximum backwater at the west edge of the flood plain (1.5 ft) is greater than maximum backwater at the east edge (1.1 ft). Backwater ranging from 0.6 to 0.2 ft. extends more than a mile downstream from the Pearl River bridge opening in I-10 at the east edge of the flood plain, and drawdown of 0.2 ft. or more occurs along approximately 2 miles of the west edge of the flood plain downstream from I-10. The capability of the modeling system to simulate the significant features of steady-state flow in a complicated multi-channel river-flood-plain system with variable topography and vegetative was successfully demonstrated in this study.

Multiple-regression techniques were used to define the relationship between a suite of basin and climatic characteristics and flood peaks in three flood-frequency regions at a total of 95 sites. Station flood-frequency data were computed following guidelines in Bulletin I7A of the U.S. Water Resources Council. The frequency analyses are based upon weighted skew values, and adjustments for high and low outliers, and historic peak data. Regression equations for estimation of peak discharges for 0.5, 0.2, 0.1, 0.04, 0.02, and 0.01 exceedance probabilities are provided for ungaged sites. An improved sample of flood peaks and gaging stations and the definition of three flood-frequency regions reduced the standard error of estimate by about 5 percent over those for the 1977 relations. Included in this analysis were the synthetic flood-frequency data at eight sites computed using historic climatic data and 10 parameters optimized by calibration of the U.S. Geological Survey's rainfall-runoff model with storm data observed over II years. The equations are applicable to streams unaffected by regulation where the usable manmade storage is less than 4.5 million cubic feet per square mile, or by diversions or urbanization. The equations are restricted to sites where the basin indices are within a specified range outside of eastern Plymouth, Barnstable, Dukes or Nantucket Counties. In these areas, the available data do not adequately define the influence of high infiltration and storage capacities of drainage basins on floodflows.</p>","largerWorkType":{"id":18,"text":"Report"},"language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/ofr80676","collaboration":"Prepared in cooperation with the

Approximately 275 coal thickness measurements obtained from drill hole data are evenly distributed throughout the area. The Cache coal and associated beds are in the Paleocene Tongue River Member of the Fort Union Formation. The depth from the surface to the Cache bed ranges from 269 to 1,257 feet. The thickness of the coal is as much as 31 feet, but in places the Cache coal bed is absent. Comparisons between hand-drawn and computer-generated isopach maps show minimal differences. Total coal resources calculated by computer show the bed to contain 2,316 million short tons or about 6.7 percent more than the hand-calculated figure of 2,160 million short tons.","language":"ENGLISH","publisher":"U.S. Geological Survey,","doi":"10.3133/ofr82402","usgsCitation":"Schneider, G.B., Crowley, S., and Carey, M., 1982, Application of computer graphics to generate coal resources of the Cache coal bed, Recluse geologic model area, Campbell County, Wyoming: U.S. Geological Survey Open-File Report 82-402, 17 p., ill., maps ;28 cm., https://doi.org/10.3133/ofr82402.","productDescription":"17 p., ill., maps ;28 cm.","costCenters":[],"links":[{"id":142357,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/1982/0402/report-thumb.jpg"},{"id":38801,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1982/0402/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4ac6e4b07f02db67aaac","contributors":{"authors":[{"text":"Schneider, G.

The Minjur was modeled as a confined aquifer recharged by leakage through underlying confining beds. Pumpage was simulated for a 23-year period during which it increased from 2,160 to 220 ,000 cubic meters per day. At Riyadh, the top of the Minjur aquifer is about 1200 meters below land surface. Aquifer thickness within the 40,000-square-kilometer study area ranges from 74 to 138 meters inclusively. Values for aquifer characteristics used in the model are: transmissivity, from 0.001 to 0.0062 square meters per second; storage coefficients, 0.07 for the unconfined, and 0.0004 for the confined sectors of the model area. A value of 0.02 meters per second was used to represent the vertical conductivity of the confining bed. Predictive simulations indicate that if the Minjur aquifer in the Riyadh area is stressed by estimated future pumpages, static water-level declines ranging from 10 up to and including 90 meters, depending on location, will occur from 1980 through 1999. Simulations also demonstrated that pumping levels in the new Buwayb well field will decline substantially from 1980 through 1981.
