Plutonic rocks, mostly granite and granodiorite, are widely distributed in the west two-thirds of the Tonopah 1 degree by 2 degree quadrangle, Nevada. These rocks were systematically studied as part of the Tonopah CUSMAP project. Studies included field mapping, petrographic and modal analyses, geochemical studies of both fresh and altered plutonic rocks and altered wallrocks, and K-Ar and Rb-Sr radiometric dating. Data collected during this study were combined with previously published data to produce a 1:250,000-scale map of the Tonopah quadrangle showing the distribution of individual plutons and an accompanying table summarizing composition, texture, age, and any noted hydrothermal alteration and mineralization effects for each pluton.
\nThe main areas mapped as part of this study, mapped along with collaborators listed in parentheses, were the Paradise Range (N.J. Silberling), north Cedar Mountain (R.A. Armin), the east side of the Toiyabe Range (G. F. Brem and R. A. Armin), and the south end of the Toquima Range (R.A. Armin). Most mapping was done at a scale of 1:24,000. These maps were combined with previously published maps and other maps of the Tonopah CUSMAP project to produce this pluton map
\nThe accompanying table includes the name (if any) of the pluton and its location, the age of the pluton (either a radiometric age or an age inferred from field relations), modal composition, texture, mineralogy, hydrothermal alteration and mineralization related to the pluton, the source of mapping shown on this map, and published references on the pluton. Radiometric ages are either published K-Ar and fission track ages or new whole-rock Rb-Sr ages determined by A. C. Robinson on samples collected either for this study or as part of regional Sr-isotope studies by R.W. Kistler and A.C. Robinson. K-Ar ages published prior to 1977 are corrected using the new I.U.C.S. constants (Steiger and Jager, 1977). Muscovite alteration ages are reported for several plutons and represent minimum ages for emplacement of these plutons. Compositional classification follows the T. J. G.S. system (“Streckeisen, 1976) and is based either on modal analyses of slabs or estimates from hand specimens. All modes, unless otherwise noted, were measured in this study. The number of modes determined is shown in parentheses, and the range in volume percent of major minerals is given. Where no modal data are available, the color index (percentage of mafic minerals) and major mafic minerals are given for most plutons. Data tabulated on hydrothermal alteration and mineralization related to plutons are based on observations made during field studies for this project. Clear genetic relation between granitic plutonism and several mineral deposits previously attributed to granitic plutonism were not substantiated, and these inconsistencies are noted in the table.

When combined with regional gravity-anomaly data, the profiles are adequate for construction of a structural model of the ring complex based on gravity models.
\nThe resulting structural model, based on profile fits to gravity responses of three-dimensional models and excess-mass calculations, gives a depth estimate to the base of the complex of 4.75 km. The contacts of the complex are inferred to be steeply dipping inward along the southwest margin of the structure. To the north and east, however, the basal contact of the complex dips more gently inward (about 30 degrees). The ring structure appears to be composed of three laccolith-shaped plutons; two are granitic in composition and make up about 85 percent of the volume of the complex, and one is granodioritic and comprises the remaining 15 percent. The source area for the plutons appears to be in the southwest quadrant of the Uyaijah ring structure. A northwest-trending shear zone cuts the northern half of the structure and contains mafic dikes that have a small but identifiable gravity-anomaly response. The structural model agrees with models derived from geological interpretation except that the estimated depth to which the structure extends is decreased considerably by the gravity results.

A detailed data base and data management system has been developed to facilitate modeling of the watershed for water quality planning purposes; statistical analysis; plotting of meteorologic, hydrologic and water quality data; and geographic data analysis. The system is Maryland 's prototype for development of a basinwide water quality management program. A key step in the program is to build a calibrated and verified water quality model of the basin using the Hydrological Simulation Program--FORTRAN (HSPF) hydrologic model, which has been used extensively in large-scale basin modeling. The compilation of the substantial existing data base for preliminary calibration of the basin model, including meteorologic, hydrologic, and water quality data from federal and state data bases and a geographic information system containing digital land use and soils data is described. The data base development is significant in its application of an integrated, uniform approach to data base management and modeling.

This map shows only those earthquakes with epicenters located within the boundaries of Vermont, even though earthquakes in nearby states or countries may have been felt or may have caused damage in Vermont.
\nThe data in table 1 were used to compile the seismicity map; these data are a corrected, expanded, and updated (through 1983) version of the data used by Algermissen (1969) for a study of seismic risk in the United States. The locations and intensities of some earthquakes were revised and intensities were assigned where none had been before. Many earthquakes were added to the original list from new data sources as well as from some old data sources that had not been previously used. The data in table 1 represent best estimates of the location of the epicenter, magnitude, and intensity of each earthquake on the basis of historical and current information. Some of the aftershocks from large earthquakes are listed, but not all, especially for earthquakes that occurred before seismic instruments were universally used.
\nThe latitude and longitude coordinates of each epicenter were rounded to the nearest tenth of a degree and sorted so that all identical locations were grouped and counted. These locations are represented on the map by a triangle. The number of earthquakes at each location is shown on the map by the arabic number to the right of the triangle. A Roman numeral to the 1eft of a triangle is the maximum Modified Mercalli intensity (Wood and Neumann, 1931) of all earthquakes at that geographic location. The absence of an intensity value indicates that no intensities have been assigned to earthquakes at that location. The year shown below each triangle is the latest year for which the maximum intensity was recorded.

Before construction of the power project in 1962, the configuration of the potentiometric surface in the upper part of the Silurian Lockport Dolomite generally paralleled the buried upper surface of the bedrock. Ground water in the central and east parts of the city of Niagara Falls flowed south and southwestward toward the upper Niagara River (above the falls), and ground water in the western part flowed westward into Niagara River gorge. The power project consists of two hydroelectric powerplants separated by a forebay canal that receives water from the upper Niagara River through two 4-mi-long, parallel, buried conduits. During periods of nonpeak power demand, some water in the forebay canal is pumped to a storage reservoir for later release to generate electricity during peak-demand periods. Since the power project began operation in 1962, groundwater within 0.5 mi of the buried conduits has seeped into the drain system that surrounds the conduits, then flows both south from the forebay canal and north from the Niagara River toward the Falls Street tunnel--a former sewer that crosses the conduits 0.65 mi north of the upper Niagara River. Approximately 6 million gallons of ground water a day leaks into the Falls Street tunnel, which carries it 2.3 mi westward to the Niagara River gorge below the falls. Daily water-level fluctuations in the forebay canal affect water levels in the drain system that surrounds the conduits, and this , in turn, affects the potentiometric surface in the Lockport Dolomite within 0.5 mi of the conduits. The drains transmit changes in pressure head near the forebay canal southward at least as far as the Falls Street tunnel area and possibly to the upper Niagara River. Some water in the pumped-storage reservoir recharges ground water in the Lockport Dolomite by seepage through bedding joints, which are exposed in the unlined reservoir bottom, and through the grout curtain beneath the reservoir 's dike. Water-level fluctuations in the reservoir cause slight ground-water fluctuations near the reservoir.

Mineral surveys were requested for 31,371 acres of the Fort Piute Wilderness Study Area. In this report the area studied is referred to as \"the study area\". Examination of mines and prospects in the area was accomplished by the U.S. Bureau of Mines in 1981 and 1982. Field investigations of the area were carried out by the U.S. Geological Survey in 1983 and 1985. No mines or prospects, few mining claims, and no identified resources are located within the wilderness study area. Moderate and low potential for gold resources appears limited to outcrops of gneiss and granite exposed along the eastern side of the Piute Range. Available information indicates that there is no potential for energy resources, including oil and gas, uranium, or geothermal, in the study area.

In this report the studied area is called the 'wilderness study area', or simply the 'study area.' No identified mineral or energy resources occur within the study area. The southern part of the area has moderate mineral resource potential for undiscovered gold and silver, and the Woodruff Formation in the southern part of the area has high resource potential for undiscovered vanadium, zinc, selenium, molybdenum, and silver (fig. 1). This assessment is based on field geochemical studies in 1984 and 1985 by the U.S. Bureau of Mines and field geochemical studies and geologic mapping by the U.S. Geological Survey in 1984 and 1985. The remainder of the study area has low resource potential for undiscovered gold, silver, lead, zinc, manganese, tin, and molybdenum. The study area also has low resource potential for undiscovered oil and gas resources.\r\n\r\nThe Antelope Wilderness Study Area is about midway between Tonopah and Eureka, Nev., in the northern Hot Creek Range and southern Antelope Range of central Nevada. It is accessible by unimproved dirt roads extending 20 mi (miles) north from U.S. Highway 6 and 40 mi south from U.S. Highway 50 (fig. 2). Most of the study area consists of rugged mountainous terrain having approximately 2,600 ft (feet) of relief. The mountain range is a block tilted gently to the east and bounded on both sides by normal faults that dip steeply to moderately west and have major displacements. Most of the study area is underlain by a thick sequence of Tertiary volcanic rocks that predominantly consist of silicic ash-flow tuff, the Windous Butte Formation. Paleozoic and lower Mesozoic (see geologic time chart in appendix) marine sediments occur along the southern margin of the study area, and lower Paleozoic rocks are exposed in the northeast corner.\r\n\r\nThe areas of exposed Paleozoic-Mesozoic rocks along the southern margin of the study area have moderate mineral resource potential for gold and silver in sediment-hosted, disseminated, epithermal (low-temperature) gold-silver deposits (fig. 1). These rocks consist of folded and thrust-faulted, fine-grained clastic sediments and limestone and dolomite that locally have been brecciated and hydrothermally altered. The alteration (locally, strong silicification) and geochemical associations of these rocks indicate a favorable environment for such deposits. Exploration for disseminated gold deposits in the same geologic environment is currently being conducted just south of the study area. The remainder of the study area has low resource potential for epithermal gold and silver vein deposits in the Tertiary volcanic rocks. The Cenozoic sedimentary basins adjacent to the fault-bounded mountain block have moderate potential for petroleum resources; the study area itself has low potential for petroleum resources.","language":"ENGLISH","publisher":"U.S. Geological Survey","doi":"10.3133/b1731E","usgsCitation":"Hardyman, R.F., Poole, F.G., Kleinhampl, F., Turner, R.L., Plouff, D., Duval, J.S., Johnson, F.L., and Benjamin, D.A., 1987, Mineral Resources of the Antelope Wilderness Study Area, Nye County, Nevada: U.S. Geological Survey Bulletin 1731, Report: vi, E19; Plate: 24 x 35.5 inches, https://doi.org/10.3133/b1731E.","productDescription":"Report: vi, E19; Plate: 24 x 35.5 inches","costCenters":[{"id":595,"text":"U.S. Geological Survey","active":false,"usgs":true}],"links":[{"id":95956,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/bul/1731e/report.pdf","size":"4055","linkFileType":{"id":1,"text":"pdf"}},{"id":95957,"rank":400,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/bul/1731e/plate-1.pdf","size":"5694","linkFileType":{"id":1,"text":"pdf"}},{"id":164332,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/bul/1731e/report-thumb.jpg"}],"geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -116.41666666666667,38.666666666666664 ], [ -116.41666666666667,39.083333333333336 ], [ -116.16666666666667,39.083333333333336 ], [ -116.16666666666667,38.666666666666664 ], [ -116.41666666666667,38.666666666666664 ] ] ] } } ] }","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a61e4b07f02db6357a5","contributors":{"authors":[{"text":"Hardyman, Richard F.","contributorId":44206,"corporation":false,"usgs":true,"family":"Hardyman","given":"Richard","email":"","middleInitial":"F.","affiliations":[],"preferred":false,"id":210517,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Poole, Forrest G. 0000-0001-8487-0799 bpoole@usgs.gov","orcid":"https://orcid.org/0000-0001-8487-0799","contributorId":1543,"corporation":false,"usgs":true,"family":"Poole","given":"Forrest","email":"bpoole@usgs.gov","middleInitial":"G.","affiliations":[{"id":171,"text":"Central Mineral and Environmental Resources Science Center","active":true,"usgs":true}],"preferred":true,"id":210514,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Kleinhampl, Frank J.","contributorId":105297,"corporation":false,"usgs":true,"family":"Kleinhampl","given":"Frank J.","affiliations":[],"preferred":false,"id":210520,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Turner, Robert L.","contributorId":45283,"corporation":false,"usgs":true,"family":"Turner","given":"Robert","email":"","middleInitial":"L.","affiliations":[],"preferred":false,"id":210518,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Plouff, Donald","contributorId":94657,"corporation":false,"usgs":true,"family":"Plouff","given":"Donald","email":"","affiliations":[],"preferred":false,"id":210519,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Duval, Joe S.","contributorId":41064,"corporation":false,"usgs":true,"family":"Duval","given":"Joe","email":"","middleInitial":"S.","affiliations":[],"preferred":false,"id":210516,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Johnson, Fredrick L.","contributorId":37392,"corporation":false,"usgs":true,"family":"Johnson","given":"Fredrick","email":"","middleInitial":"L.","affiliations":[],"preferred":false,"id":210515,"contributorType":{"id":1,"text":"Authors"},"rank":7},{"text":"Benjamin, David A.","contributorId":108159,"corporation":false,"usgs":true,"family":"Benjamin","given":"David","email":"","middleInitial":"A.","affiliations":[],"preferred":false,"id":210521,"contributorType":{"id":1,"text":"Authors"},"rank":8}]}} ,{"id":80303,"text":"fwsobs82_10_133 - 1987 - Habitat Suitability Index Models: Juvenile English sole","interactions":[],"lastModifiedDate":"2022-01-28T17:23:12.362574","indexId":"fwsobs82_10_133","displayToPublicDate":"1994-01-01T00:00:00","publicationYear":"1987","noYear":false,"publicationType":{"id":18,"text":"Report"},"publicationSubtype":{"id":1,"text":"Federal Government Series"},"seriesTitle":{"id":20,"text":"FWS/OBS","active":false,"publicationSubtype":{"id":1}},"seriesNumber":"82/10.133","subseriesTitle":"Habitat Suitability Index","title":"Habitat Suitability Index Models: Juvenile English sole","docAbstract":"English sole (Parophrys vetulus) is one of the major commercial groundfish species caught along the Pacific coast.

The bulk of this gold was recovered from the western slope of the northern half of the Sierra Nevada between the Merced River in the south and the Feather River to the north, a distance of about 170 mi. Gold was first discovered, in this region, on the American River at Coloma in 1848, triggering the famed California gold rush. Mining was continuously active, somewhere in the area, from the discovery of gold until World War II when mining was legally prohibited. Dramatic increases in gold prices in the past decade coupled with recent advances in extractive techniques have revitalized prospecting, and major deposits are currently being explored and developed.
\nGold has been found in a variety of geologic environments in the region. In addition to production from the complex vein systems of the historically famous Mother Lode and associated East Gold Belt and West Gold Belt, large amounts of gold have also been recovered from the Grass Valley-Nevada City and other isolated lode districts and from Tertiary river channels and Quaternary alluvium.
\nThis oblique map illustrates the relation of the different gold-bearing environments to each other and to the general terrain of the northern Sierra Nevada. The map was derived from the 1970 U.S. Geological Survey 1:500,000-scale topographic map of California and the 1976 U.S. Geological Survey 1:500,000-scale topographic map of Nevada, using an isometrograph, a mechanical instrument that produces an oblique framework by tracing individual contours. Form lines sketched over this framework graphically portray the physiographic configuration of the region. Relief on the oblique map has a 3:1 vertical exaggeration and appears as if viewed from a 30° angle above the horizon.
\nLocations of lode gold prospects and mines shown on the map were obtained from the U.S. Geological Survey's Mineral Resource Data System (MRDS), a computerized mineral-resource information file, and plotted in their respective locations (D.F. Huber, written commun., 1986). Some locations from two northern counties, missing from the MRDS retrival, were added. The twenty lode mines believed to be the most productive are cited in table 1. A total of nearly 4,000 sites, including both prospects and mines, were initially plotted, but about a third of those were obscured by topography on the oblique map. Locations of Tertiary river channels and gold-dredging fields were taken from published general references modified by examining specific sources and by cursory field examination. Seven of the major dredge fields are identified in table 2.

A weighted least-square (WLS) regression model was used to generalize the coefficients of station skewness that resulted in a root-mean-sq error of prediction of 0.35 compared to 0.55 for the skewness map published in Bulletin 17B of the U.S. Water Resources Council. Estimates of generalized skewness were computed for each of 245 streamflow gaging stations with a minimum of 10 years of record and a contributing drainage area of < 20,000 sq mi. The WLS regression model also was used to develop equations for estimating flood magnitude for selected recurrence intervals for ungaged stream locations by using data from 218 of the 245 streamflow gaging stations that had contributing-drainage areas of less than 10,000 sq mi. The errors of prediction of the most reliable WLS equations ranged from 28 to 42%. The WLS equations were compared statistically to previous developed equations and were determined to be different and more accurate than previously published equations. Flood magnitudes and frequencies for 245 streamflow gaging stations, based on data collected through the 1983 water year, are presented along with a summary of the seasonal distribution of annual maximum discharges and an analysis of the maximum observed discharges.

Interpretation of geologic and geophysical information indicates that the main structure of McMullen Valley is a syncline that has been normal faulted on the southeast side. Basin fill that accumulated in the structural depression during late Miocene to Pleistocene time is the main aquifer and is divided into upper and lower units on the basis of lithologic information. The upper unit is a thin layer of coarse-grained sediments and generally is not saturated. The lower unit is 3,000 to 4,000 ft thick, includes a fine-grained facies in the upper 1,000 ft, and is the main source of water. The fine-grained facies is found in the southwest half of the basin and is further divided into upper and lower parts. The lower part of the fine-grained facies has: a higher percentage of silt and clay than the upper part, contains evaporites, does not yield water to wells, and separates the aquifer into shallow and deep systems. A numerical model was used to analyze the groundwater system for both steady-state and transient conditions. The transient model was used to analyze system response to pumping stress. The transient system is one of storage depletion, and water level declines are controlled by pumping and specific yield distributions. Water level declines are also influenced by hydraulic properties and areal extent of the fine-grained facies. Significant water level declines may extend to aquifer boundaries in most of the basin; in one area, impermeable boundary greatly influences declines. The location of the nearby boundary was estimated through gravity data modeling. Several hydrologic components, including hydraulic properties and areal extent of the fine-grained facies , storage properties, and aquifer boundaries, need better definition in order to develop a more accurate model of the groundwater system.

The first model, calibrated prior to this study, had 10-mi grid spacing. The mean difference between the simulated and measured pre-development water levels in this model was +0.28 ft with a standard deviation of 25.8 ft. The second model, calibrated during this study independently of the first model, had 5-mi grid spacing. The mean difference between the simulated and measured pre-development water levels was -0.01 ft with a standard deviation of 44.4 ft. For 1980 water levels, the mean difference was +8.22 ft with a standard deviation of 27.9 ft. The results from the first and second models were compared. The standard deviation of the differences in simulated water levels was 19.0 ft for the pre-development period and 21.8 ft for 1980. There appeared to be no hydrologic significance to the pattern of the differences. A third model, constructed by aggregating the data from the second model, had 10-mi grid spacing. The mean difference in simulated pre-development water levels between the second and third models was +0.86 ft with a standard deviation of 8.9 ft. For the 1980 water levels, the mean difference between the models was +0.39 ft with a standard deviation of 4.4 ft. The study found that the same hydrologic conclusions would have been reached had 5-mi grid spacing or 10-mi grid spacing been used. It was further concluded that the difference in simulated water levels between models with 5-mi grid spacing or 10-mi grid spacing was five to six times smaller than the differences between the simulated and measured water levels.

Most groundwater moves through solution-widened bedding planes, although some moves through vertical joints. The yield of water from 42 wells ranges from 3 to 100 gal/min, averaging 20 gal/min. Groundwater levels in the Onondaga aquifer declined during the fall of 1981 and summer and fall of 1982-85, near a 2.2-mile-long and 800-foot-wide land surface depression in the eastern part of Erie County. More than 60 wells and several wetlands went dry and at least three sinkholes developed. Groundwater levels were measured in 150 wells during a high water level period in April 1984 and a low water period in October 1984. Water levels fluctuated 20 to 50 ft near the depression and near the quarries but fluctuated only 5 to 10 ft elsewhere. The water level decline was caused by the combined effect of groundwater removal by pumpage from a quarry (the water is then discharged to Dorsch Creek) and by the swallets in the 2.2-mile-long depression area, which are recharge points for the aquifer. In 1982, sinkholes formed in a surface depression area in Harris Hill. The enlargement of these sinkholes seems to be unrelated to the water level decline in the eastern part of the county and is probably caused by local drainage alterations.

The study area, known as the Pinon Canyon Maneuver Site, drains into the Purgatoire River, a major tributary of the upper Arkansas River. A multidisciplined hydrologic investigation began in October 1982. The primary aquifer in the Maneuver Site is the Dakota-Purgatoire. Well yields generally range from 10 to 500 gal/min. Dissolved solids concentrations in groundwater ranged from 195 to 6,150 mg/L. Streamflow in the Purgatoire River is perennial. Tributaries draining the Maneuver Site are intermittent or ephemeral and contribute only about 4.4% of the streamflow of the Purgatoire River downstream from the Maneuver Site. Flood frequencies were calculated by using the log Pearson III procedure and compared well with a regional estimating technique that was developed that uses physical drainage-basin characteristics. Calcium and sulfate are the predominant ions in the surface water of the area. Time-series plots indicate that instream water-quality standards for nitrate and metals are exceeded. About 80% of the suspended-sediment load is transported by rainfall runoff, which occurs less than 8% of the time. Ephermal tributaries contributed less than 25% of the suspended-sediment load transported to the Purgatoire River downstream from the Maneuver Site. Historic annual mean sediment yields were measured for 29 small watersheds. Sediment yields were measured for 29 small watersheds. Sediment yields ranged from 9.5 to 1,700 tons/sq mi. Sediment yields were estimated by a multiple-linear-regression model developed by using physical drainage-basin characteristics and by the Pacific Southwest Interagency Committee method.
