This district is one of many located on or near the Melones fault zone, a major regional suture in the Sierra Nevada foothills. The districts along the Melones fault comprise the Mother Lode gold belt (Clark, 1970).\n\nThe Harvard pit is the largest of several open pits mined at the Jamestown site by Sonora Mining Corporation between 1986 and 1994 (Fig. 2; Algood, 1990). It is at the site of an historical mine named the Harvard that produced about 100,000 troy ounces of gold, mainly between 1906 and 1916 (Julihn and Horton, 1940).\n\nSonora Mining mined and processed about 17,000,000 short tons of ore, with an overall stripping ratio of about 4.5:1, yielding about 660,000 troy ounces of gold (Nelson and Leicht, 1994). Most of this material came from the Harvard pit, which attained dimensions of about 2700 ft (830 m) in length, 1500 ft (460 m) in width, and 600 ft (185 m) in depth. The bottom of the pit is at an elevation of 870 ft (265 m). Since mining operations ceased in mid-1994, the open pit has been filling with water. As of November, 2000, lake level had reached an elevation of about 1170 ft (357 m).\n\nWater quality monitoring data gathered after mine closure showed rising levels of arsenic, sulfate, and other components in the lake, with particularly notable increases accompanying a period of rapid filling in 1995 (County of Tuolumne, 1998). The largest potential source for arsenic in the vicinity of the Harvard pit is arsenian pyrite, the most abundant sulfide mineral related to gold mineralization. A previous study of weathering of arsenian pyrite in similarly mineralized rocks at the Clio mine, in the nearby Jacksonville mining district, showed that arsenic released by weathering of arsenian pyrite is effectively attenuated by adsorption on goethite or coprecipitation with jarosite, depending upon the buffering capacity of the pyrite-bearing rock (Savage and others, 2000). Although jarosite would be expected to dissolve in water having the composition of the developing pit lake, iron oxyhydroxide species (ferrihydrite and goethite) would be stable, and strong partitioning of arsenic onto suspended particles or bottom sediments containing these iron phases would be expected. Arsenic release to the lake would not be expected until stratification develops, producing a reducing, non-circulating hypolimnion in which the iron phases would be destroyed by dissolution.\n\nThe fact that arsenic concentrations increased rapidly before the pit lake was deep enough to stratify shows that arsenic may not be attenuated in the ways that the earlier Clio mine area study indicated, and suggested that our understanding of release and transport of arsenic in this environment is incomplete. Therefore, in 1997 we decided to study the chemical evolution of the Harvard pit lake as part of a project on environmental impacts of gold mining in the Sierra Nevada, and in early 1998 we developed a cooperative study with several of the investigators in the Stanford University Department of Geological and Environmental Sciences who had done the Clio study. The U.S. Geological Survey portion of the project has been funded by the Mineral Resources Program.\n\nIt is anticipated that a better understanding of the release and transport of arsenic into the Harvard pit lake and its accumulation there will contribute to more accurate predictions of arsenic release from weathering of sulfide-bearing rocks exposed by mining or other activities or events, and to better forecasts of pit lake evolution in this and similar environments, leading to more effective monitoring and mitigation strategies.\n\nAn accurate predictive model is needed for the Harvard pit lake to forecast trends in metal concentrations, particularly arsenic, and also concentrations of major cations and anions. As the lake approaches pre-mining groundwater levels the lake water could move down the hydrologic gradient to the southeast into domestic wells, and could also affect the surface water of Woods Creek (see Figures 1-3).\n\nThis report presents data for water samples collected from March, 1998 through September, 1999. Selected preliminary data for the pit lake for the 1998 calendar year have been reported (Savage and others, 2000).","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","doi":"10.3133/ofr0174","usgsCitation":"Ashley, R.P., and Savage, K.S., 2001, Analytical data for waters of the Harvard Open Pit, Jamestown Mine, Tuolumne County, California, March 1998-September 1999: U.S. Geological Survey Open-File Report 2001-74, Report: ii, 13 p.; 3 Tables; Data Table, https://doi.org/10.3133/ofr0174.","productDescription":"Report: ii, 13 p.; 3 Tables; Data Table","numberOfPages":"15","temporalStart":"1998-03-01","temporalEnd":"1999-09-30","costCenters":[{"id":312,"text":"Geology, Minerals, Energy, and Geophysics Science Center","active":true,"usgs":true}],"links":[{"id":160560,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/ofr0174.jpg"},{"id":282004,"rank":6,"type":{"id":27,"text":"Table"},"url":"https://pubs.usgs.gov/of/2001/0074/tables2-4.xls","text":"Tables 2-4 Excel format","linkFileType":{"id":3,"text":"xlsx"}},{"id":2803,"rank":8,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/of/2001/0074/","linkFileType":{"id":5,"text":"html"}},{"id":282003,"rank":5,"type":{"id":27,"text":"Table"},"url":"https://pubs.usgs.gov/of/2001/0074/pdf/table4.pdf","text":"Table 4","linkFileType":{"id":1,"text":"pdf"}},{"id":282002,"rank":4,"type":{"id":27,"text":"Table"},"url":"https://pubs.usgs.gov/of/2001/0074/pdf/table3.pdf","text":"Table 3","linkFileType":{"id":1,"text":"pdf"}},{"id":282001,"rank":3,"type":{"id":27,"text":"Table"},"url":"https://pubs.usgs.gov/of/2001/0074/pdf/table2.pdf","text":"Table 2","linkFileType":{"id":1,"text":"pdf"}},{"id":282000,"rank":2,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/2001/0074/pdf/of01-074.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":407176,"rank":7,"type":{"id":36,"text":"NGMDB Index Page"},"url":"https://ngmdb.usgs.gov/Prodesc/proddesc_37339.htm","linkFileType":{"id":5,"text":"html"}}],"country":"United States","state":"California","county":"Tuolumme County","otherGeospatial":"Jamestown Mine","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -120.453,\n              37.955\n            ],\n            [\n              -120.405,\n              37.955\n            ],\n            [\n              -120.405,\n              37.93\n            ],\n            [\n              -120.453,\n              37.93\n            ],\n            [\n              -120.453,\n              37.955\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4acee4b07f02db67fa7f","contributors":{"authors":[{"text":"Ashley, R.

The U.S. Geological Survey designed and operated a streamflow and water quality\nmonitoring network in the basin during the 1999 water year (October 1, 1998, through September 30, 1999) in support of this Remedial Investigation/Feasibility Study. The objective for\nthe network was to quantify the absolute and relative magnitude of hydrologic, trace-element, and nutrient loads transported by numerous stream reaches within the Spokane River Basin. Of the 29 water-quality stations in the network, 19 were in the Coeur d?Alene River Basin, 2 were in the St. Joe River Basin, and the remaining 8 were on the Spokane River downstream from Coeur d'Alene Lake. All stations were sampled for whole-water recoverable and dissolved concentrations of cadmium, lead, and zinc. Nitrogen and phosphorus concentrations were sampled at nine stations to determine loads of nutrients into and out of Coeur d'Alene Lake and transported down the Spokane River into the Columbia River. Mean daily discharge during the 1999 water year was about 120 percent of the long-term average. Trace-element loads to the Columbia River were calculated for the basin's terminal station, Spokane River at Long Lake. For whole-water recoverable cadmium, 2,110 pounds, 92 percent of which was dissolved, was delivered to the Columbia River. The Columbia River received 25,000 pounds of whole-water recoverable lead, 29 percent of which was dissolved, from the Spokane River Basin. The largest trace-element load delivered to the Columbia River by the Spokane River was 764,000 pounds of whole-water recoverable zinc, 76 percent of which was dissolved. The primary source of trace-element loads in the Spokane River Basin was the Coeur d'Alene River Basin. The South Fork Coeur d'Alene River was the largest source of dissolved and wholewater recoverable loads of cadmium and zinc. In contrast, the main stem of the Coeur d'Alene River was the largest source of dissolved and wholewater recoverable loads of lead. Within the South Fork, substantial increases in dissolved loads of cadmium, lead, and zinc were detected in excess of those measured by the monitoring network stations upstream from the terminal station, South Fork Coeur d'Alene River near Pinehurst. Much of the added load was attributed to inflow of traceelement-contaminated ground water. Similarly, increases in whole-water recoverable loads of cadmium, lead, and zinc were detected in the South Fork in excess of measured loads; these were attributed largely to erosion and transport of sediment-associated trace elements during increased stream discharge events. Coeur d'Alene Lake received nearly all its trace-element loads from the Coeur d'Alene River. The lake retained the majority of the dissolved and whole-water recoverable loads of lead input to it, but retained almost none of its dissolved and whole-water recoverable loads of zinc. About one-half of the dissolved and whole-water recoverable loads of cadmium was retained in the lake. Within the Spokane River Basin, the largest loads of total nitrogen, 13,000,000 pounds, and total phosphorus, 677,000 pounds, were measuredat Spokane River at Long Lake, the station closest to the Columbia River. At Coeur d'Alene Lake, total nitrogen loads input to the lake from the Coeur d'Alene and St. Joe Rivers totaled 1,890,000 pounds; the lake discharged 2,430,000 pounds. The lake received 253,000 pounds of total phosphorus and discharged 187,000 pounds; thus, 66,000 pounds was retained by the lake.","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","doi":"10.3133/ofr00441","collaboration":"Prepared in cooperation with U.S. Environmental Protection Agency","usgsCitation":"Woods, P.F., 2001, Concentrations and loads of cadmium, lead, zinc, and nutrients measured during the 1999 water year within the Spokane River basin, Idaho and Washington: U.S. Geological Survey Open-File Report 2000-441, iv, 32 p., https://doi.org/10.3133/ofr00441.","productDescription":"iv, 32 p.","numberOfPages":"38","costCenters":[{"id":343,"text":"Idaho Water Science Center","active":true,"usgs":true}],"links":[{"id":262350,"rank":800,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/2000/0441/report.pdf"},{"id":262351,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/2000/0441/report-thumb.jpg"}],"country":"United States","state":"Idaho","otherGeospatial":"Coeur D'alene River Basin;St. Joe River Basin;Coeur D'alene Lake;Long Lake","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -118.4966,46.753 ], [ -118.4966,47.9947 ], [ -114.9876,47.9947 ], [ -114.9876,46.753 ], [ -118.4966,46.753 ] ] ] } } ] }","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4b16e4b07f02db6a55d6","contributors":{"authors":[{"text":"Woods, P.

A comparison of instantaneous base-flow loads of NO2t+NO3t indicates\r\nthat at base-flow conditions, most NO2t+NO3t discharged by Shoal Creek is from nonpoint sources. Nearly all the base-flow instantaneous\r\nload of total phosphorus as P (Pt) discharged\r\nby Shoal Creek can be attributed to effluent from a municipal wastewater treatment plant. Samples collected from a single runoff event indicate that substantial quantities of Pt can be transported during runoff events compared to base-flow transport. Only minor quantities of NO2t+NO3t are transported during runoff events compared to base-flow transport. Fecal coliform bacteria densities at several locations exceed the Missouri Department of Natural\r\nResources (MDNR) standard of 200 col/100 mL (colonies per 100 milliliters) for whole-body contact recreation. During 13 months of monitoring\r\nat 13 stream sites, fecal coliform densities (median of 277 and 400 col/100 mL) at two sites (sites 2 and 3) on Shoal Creek exceeded the MDNR standard at base-flow conditions. The maximum fecal coliform density of 120,000 col/100 mL was detected at site 3 (MDNR monitoring\r\nsite) during a runoff event in April 1999 at a peak discharge of 1,150 ft3/s (cubic feet per second).\r\nFecal coliform densities also exceeded the MDNR standard in three tributaries with the largest\r\ndensities (median of 580 col/100 mL) detected in Pogue Creek. Results of ribopattern analyses indicate that most Escherichia coli (E. coli) bacteria in water samples from the study area probably are from nonhuman sources. The study area contains about 25,000 cattle, and has an estimated annual production\r\nof 33 million broilers and 300,000 turkeys. Probable nonhuman sources included turkeys, horses, chickens, and cattle; however, wildlife sources such as deer, raccoon, muskrat, and opossum\r\nwere not evaluated. Human waste was an important source of E. coli in water samples collected\r\nat the MDNR monitoring site (site 3) on Shoal Creek and at two tributary sites (Joyce Creek and Woodward Creek). In general, the detection of human ribopatterns was consistent with the detection of organic compounds commonly\r\nassociated with human wastewater such as caffeine, triclosan, or phenol, and the fecal indicators\r\ncholesterol and 3B-coprostanol. Ribopattern analysis indicate that horses were an important source of E. coli in Woodward Creek, which was consistent with horses being pastured immediately upstream from the sampling site on this creek. Pogue Creek contains a large density of turkey barns and five of eight E. coli isolates from one sample from Pogue Creek were matched to turkeys.\r\nWater samples from Pogue Creek generally did not contain detectable concentrations of human wastewater compounds, but one sample did contain detectable quantities of the antibiotics tylosin and lincomycin (widely used in the animal industry), and sulfamethoxazole (human use only). Although promising, the ability of ribopattern\r\nanalyses to positively identify the source of a particular isolate is uncertain because of the small sample size, possible differences between animal source patterns in the study area and database used, lack of native wildlife source patterns, and variation in results depending on the number of possible animal host considered. Results of this study indicate that a trend of increasing fecal coliform densities with increasing time detected by the MDNR is, in part, caused by trends in annual precipitation and stream discharge,\r\nand not necessarily changes in land use or densities of animal operations.

Three of the nine characteristics define the magnitude of stormwater runoff, and the remaining six characteristics describe the shape and duration of a storm hydrograph. Multiple linear regression was used to develop equations to estimate the nine stormwater runoff characteristics from basin and rainfall characteristics. Five basin characteristics and five rainfall characteristics were tested in the regressions to determine which basin and rainfall characteristics significantly affect stormwater runoff characteristics. Basin development factor was found to be significant in equations for eight of the nine stormwater runoff characteristics.

Long-term streamflow data from the Butler Creek streamflow gaging station were used along with several concurrent discharge measurements made at three selected partial-record streamflow stations on Fort Gordon to determine selected low-flow streamflow characteristics. Streamflow data were collected and analyzed using standard U.S. Geological Survey methods and computer application programs to verify the use of simple drainage area to discharge ratios, which were used to estimate the low-flow characteristics for the selected streams. Low-flow data computed based on daily mean streamflow include: mean discharges for consecutive 1-, 3-, 7-, 14-, and 30-day period and low-flow estimates of 7Q10, 30Q2, 60Q2, and 90Q2 recurrence intervals.

The cross sections transect that part of the southern Great Basin that includes Death Valley, the Nevada Test Site, and the potential high-level nuclear waste underground repository at Yucca Mountain. The specific geometric relationships portrayed on the cross sections are discussed in the context of four general sub-regions that have stratigraphic similarities and general consistency of structural style: (1) the Nevada Test Site vicinity; (2) the Spring Mountains, Pahrump Valley and Amargosa Desert region; (3) the Death Valley region; and (4) the area east of the Nevada Test Site. \r\nThe subsurface geologic interpretations portrayed on the cross sections are based on an integration of existing geologic maps, measured stratigraphic sections, published cross sections, well data, and geophysical data and interpretations. The estimated top of pre-Cenozoic rocks in the cross sections is based on inversion of gravity data, but the deeper parts of the sections are based on geologic conceptual models and are more speculative. \r\nThe region transected by the cross sections includes part of the southern Basin and Range Province, the northwest-trending Walker Lane belt, the Death Valley region, and the northern Mojave Desert. The region is structurally complex, where a locally thick Tertiary volcanic and sedimentary section unconformably overlies previously deformed Proterozoic through Paleozoic rocks. All of these rocks have been deformed by complex Neogene ex-tensional normal and strike-slip faults. These cross sections form a three-dimensional network that portrays the interpreted stratigraphic and structural relations in the region; the sections form part of the geologic framework that will be incorporated in a complex numerical model of ground-water flow in the Death Valley region.","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/mf2370","usgsCitation":"Sweetkind, D.S., Dickerson, R., Blakely, R., and Denning, P., 2001, Interpretive geologic cross sections for the Death Valley regional flow system and surrounding areas, Nevada and California: U.S. Geological Survey Miscellaneous Field Studies Map 2370, Three sheets: Sheet 1, 60 by 36 inches; sheet 2, 84 by 36 inches; sheet 3, 71 by 36 inches (all in color).

The index was developed because previous water-quality investigations raised concerns regarding inputs of bacteria, suspended sediment, and phosphorus from nonpoint sources in the watershed. A geographic information system was used to build map overlays and to categorize and rate three factors that affect the transport of water and contaminants-land-surface slope, distance to water, and land use/land cover. Each factor was weighted to reflect its potential contribution to surface-water contamination; the factors then were combined to estimate susceptibility values for the entire watershed. The numerical susceptibility values were categorized to indicate lowest to highest potential for surface-water contamination, and a map was produced showing the spatial distribution of these categories within the watershed.\n\nThe susceptibility index for about 17 percent of the Little Cross Creek watershed is rated in the high or highest category. These areas have high slopes, short distances to the nearest surface water, impervious land cover, and land uses that generate contaminants. About 38 percent of the watershed area is rated as having low or lowest susceptibility to contamination. These areas contain flat terrain, greater distances to water, land cover that promotes infiltration, and land uses that pose little risk for generating contaminants. Approximately 43 percent of the watershed is in the moderate category of susceptibility. Open water, which is not rated, accounts for the remaining area.\n\nThe susceptibility index provides water-resource managers with a tool that can aid in prioritizing areas within the Little Cross Creek Basin for monitoring, protection, and remediation. Previous suspended sediment, total phosphorus, and fecal coliform data collected in the Little Cross Creek watershed support the results of the susceptibility analysis. Although this susceptibility index is specific to the Little Cross Creek Basin, the methods used to develop the index are transferable to other watersheds.","language":"ENGLISH","doi":"10.3133/wri014143","usgsCitation":"Giorgino, M., and Terziotti, S., 2001, Susceptibility index to surface contamination for the Little Cross Creek watershed, Cumberland County, North Carolina: U.S. Geological Survey Water-Resources Investigations Report 2001-4143, 1 over-size sheet., https://doi.org/10.3133/wri014143.","productDescription":"1 over-size sheet.","costCenters":[{"id":13634,"text":"South Atlantic Water Science Center","active":true,"usgs":true}],"links":[{"id":161260,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/usgs_thumb.jpg"},{"id":274640,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/wri/2001/4143/plate-1.pdf"}],"country":"United States","state":"North Carolina","county":"Cumberland County","otherGeospatial":"Little Cross Creek","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a09e4b07f02db5facf7","contributors":{"authors":[{"text":"Giorgino, M.

The provinces are similar in many aspects of their history of development, stratigraphic composition, and petroleum geology characteristics. The sedimentary\r\ncover of the provinces overlies the Archean?Lower Proterozoic\r\nbasement of the Siberian craton. Over most of the area of the provinces, the basement is covered by Vendian (uppermost Proterozoic, 650?570 Ma) clastic and carbonate rocks. Unlike the case in the more northwestern areas of the craton, older Riphean sedimentary rocks here are largely absent and they appear in the stratigraphic sequence only in parts of the Cis-Patom Foredeep province. Most of the overlying sedimentary section consists of Cambrian and Ordovician carbonate and clastic rocks, and it includes a thick Lower Cambrian salt-bearing formation. Younger rocks are thin and are present only in marginal areas.\r\n1\r\nA single total petroleum system (TPS) embraces all three provinces. The TPS is unique in two aspects: (1) its rich hydro-carbon reserves are derived from Precambrian source rocks and (2) preservation of oil and gas fields is extremely long owing to the presence of the Lower Cambrian undeformed salt seal. Discovered\r\nreserves of the TPS are about 2 billion barrels of oil and more than 30 trillion cubic feet of gas. The stratigraphic distribution\r\nof oil and gas reserves is narrow; all fields are in Vendian to lowermost Cambrian clastic and carbonate reservoirs that occur below Lower Cambrian salt. Both structural and stratigraphic traps are known. Source rocks are absent in the sedimentary cover of the provinces, with the possible exception of a narrow zone on the margin of the Cis-Patom Foredeep province. Source rocks are interpreted here to be Riphean and Vendian organic-rich shales of the Baikal-Patom folded region. These rocks presently\r\nare deformed and metamorphosed, but they generated oil and gas before the deformation occurred in Late Silurian and Devonian time. Generated hydrocarbons migrated updip onto the craton margin. The time of migration and formation of fields is constrained by the deposition of Lower Cambrian salt and by the Late Silurian or Devonian metamorphism of source rocks. This time frame indicates that the TPS is one of the oldest petroleum systems in the world.\r\nAll three provinces are exploration frontiers, and available geologic data are limited; therefore, only one assessment unit has been identified. The largest undiscovered hydrocarbon resources are expected to be in Vendian clastic reservoirs in both structural and stratigraphic traps of the Nepa-Botuoba High province. The petroleum potential of Vendian?lowermost Cambrian carbonate reservoirs is smaller. Nevertheless, these reservoirs may contain significant resources. Gas is expected to dominate over oil in the resource base.","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/b2201C","usgsCitation":"Ulmishek, G.F., 2001, Petroleum geology and resources of the Nepa-Botuoba High, Angara-Lena Terrace, and Cis-Patom Foredeep, southeastern Siberian Craton, Russia (Version 1.0): U.S. Geological Survey Bulletin 2201, 16 p., https://doi.org/10.3133/b2201C.","productDescription":"16 p.","costCenters":[],"links":[{"id":161250,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/usgs_thumb.jpg"},{"id":462804,"rank":3,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/bul/2201/C/b2201-c.pdf","text":"Report","size":"3.65 MB","linkFileType":{"id":1,"text":"pdf"}},{"id":3237,"rank":2,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/bul/2201/C/index.html","linkFileType":{"id":5,"text":"html"}}],"edition":"Version 1.0","contact":"<p><a href=\"https://pubs.usgs.gov/contact\" data-mce-href=\"../contact\">Contact Pubs Warehouse</a></p>","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4adce4b07f02db686345","contributors":{"authors":[{"text":"Ulmishek, Gregory F.","contributorId":48971,"corporation":false,"usgs":true,"family":"Ulmishek","given":"Gregory","email":"","middleInitial":"F.","affiliations":[],"preferred":false,"id":209807,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

The province is on the western margin of the Siberian craton east of theYenisey Ridge foldbelt. The province is an exploration frontier\r\nand only a few prospects have been drilled. The oldest sedimentary\r\nrocks of the province, Riphean carbonate and clastic strata of Late Proterozoic age (1,650?650 million years old) that were deposited on the passive margin, cover the Archean?Lower Proterozoic basement. Basal Vendian (uppermost Proterozoic, 650?570 million years old) clastic rocks unconformably overlie various units of the Riphean and locally lie directly on the basement.\r\nYounger Vendian and lowermost Cambrian rocks are primarily dolomites. The Vendian/Cambrian boundary is con-formable, and its exact stratigraphic position has not been identified\r\nwith certainty. The Lower Cambrian section is thick, and it consists of alternating beds of dolomite and evaporites (mostly salt). Middle and Upper Cambrian strata are composed of shale and dolomite. Ordovician-Silurian and upper Paleozoic rocks are thin, and they are present only in the northern areas of the province.\r\nStructural pattern of Riphean rocks differs substantially from that of Vendian-Cambrian rocks.\r\nA single total petroleum system (TPS) was identified in the Baykit High province. Discovered oil of the system is chiefly concentrated in Riphean carbonate reservoirs of the Yurubchen-Tokhom zone that is currently being explored and that has the\r\nAbstract 1\r\npotential to become a giant field (or group of fields). The TPS also contains about 5 trillion cubic feet of discovered recover-able gas in clastic reservoir rocks at the base of the Vendian section.\r\nPetroleum source rocks are absent in the stratigraphic succession over most of the TPS area. Riphean organic-rich shales and carbonates that crop out in the Yenisey Ridge foldbelt west of the Baykit high are probable source rocks. Their areal distribution extends from the foldbelt into the foredeep along the province?s western margin. Potential source rocks also are present in platform depressions in eastern areas of the province. Hydrocarbon generation and migration west of the province started as early as Riphean time, before the beginning of the deformation in the Yenisey Ridge foldbelt that occurred about 820?850 million years ago. However, the presently known oil and gas accumulations were formed after deposition of the Lower Cambrian salt seal.\r\nAvailable data allow identification of only one assessment unit, and it covers the entire TPS area. Undiscovered oil and gas resources are moderate, primarily due to the poor quality of reservoir\r\nrocks. However, the reserve growth in the Yurubchen-Tokhom zone may be large and may exceed the volume of undiscovered\r\nresources in the rest of the province.

The quadrangle, situated in Joshua Tree National Park in the eastern Transverse Ranges physiographic and structural province, encompasses parts of the Hexie Mountains, Cottonwood Mountains, northern Eagle Mountains, and south flank of Pinto Basin. It is underlain by a basement terrane comprising Proterozoic metamorphic rocks, Mesozoic plutonic rocks, and Mesozoic and Mesozoic or Cenozoic hypabyssal dikes. The basement terrane is capped by a widespread Tertiary erosion surface preserved in remnants in the Eagle and Cottonwood Mountains and buried beneath Cenozoic deposits in Pinto Basin. Locally, Miocene basalt overlies the erosion surface. A sequence of at least three Quaternary pediments is planed into the north piedmont of the Eagle and Hexie Mountains, each in turn overlain by successively younger residual and alluvial deposits. The Tertiary erosion surface is deformed and broken by north-northwest-trending, high-angle, dip-slip faults and an east-west trending system of high-angle dip- and left-slip faults. East-west trending faults are younger than and perhaps in part coeval with faults of the northwest-trending set. The Porcupine Wash database was created using ARCVIEW and ARC/INFO, which are geographical information system (GIS) software products of Envronmental Systems Research Institute (ESRI). The database consists of the following items: (1) a map coverage showing faults and geologic contacts and units, (2) a separate coverage showing dikes, (3) a coverage showing structural data, (4) a scanned topographic base at a scale of 1:24,000, and (5) attribute tables for geologic units (polygons and regions), contacts (arcs), and site-specific data (points). The database, accompanied by a pamphlet file and this metadata file, also includes the following graphic and text products: (1) A portable document file (.pdf) containing a navigable graphic of the geologic map on a 1:24,000 topographic base. The map is accompanied by a marginal explanation consisting of a Description of Map and Database Units (DMU), a Correlation of Map and Database Units (CMU), and a key to point-and line-symbols. (2) Separate .pdf files of the DMU and CMU, individually. (3) A PostScript graphic-file containing the geologic map on a 1:24,000 topographic base accompanied by the marginal explanation.

It seems likely that gold deposits along these linear trends were, therefore, controlled by deep regional crustal fault systems.</p><p>Two-dimensional resistivity modeling of the magnetotelluric data generally show resistive (30 to 1,000 ohm-m) crustal blocks broken by narrow, sub-vertical, two-dimensional, conductive (1 to 10 ohm-m) zones that are indicative of large-scale crustal fault zones. These inferred fault zones are regional in scale, trend southeast-to-northwest, and extend to mid-crustal (20 km) depths. The conductors are about 3 to 15 km wide, extend from 1 to 8 km below the surface to about 20 km depth, and show two- dimensional electrical structure with general north to northwesterly strikes. From connecting the locations of the conductors together, a single regional crustal fault zone can be inferred that is about 10 km wide within the upper crust and about 150-km long. It coincides with the Battle Mountain-Eureka mineral trend. The images also show regional changes in the resistive crust from north to south. Most of Reese River Valley and Boulder Valley are underlain by a thick (20 km) southwest-to-northeast section of conductive (1 to 10 ohm-m) rock, suggesting that high-temperature fluids are more pervasive in this area (Battle Mountain Heat-Flow High), which implies that the crust beneath these valleys is more fractured than in the areas surveyed to the south.</p><pre></pre>","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/ofr01346","usgsCitation":"Rodriguez, B.D., and Williams, J.M., 2001, Deep regional resistivity structure across the Battle Mountain-Eureka and Carlin trends, north-central Nevada (Version 1.0): U.S. Geological Survey Open-File Report 2001-346, 165 p., https://doi.org/10.3133/ofr01346.","productDescription":"165 p.","costCenters":[],"links":[{"id":413772,"rank":3,"type":{"id":36,"text":"NGMDB Index Page"},"url":"https://ngmdb.usgs.gov/Prodesc/proddesc_43391.htm","linkFileType":{"id":5,"text":"html"}},{"id":2997,"rank":2,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/of/2001/ofr-01-0346/","linkFileType":{"id":5,"text":"html"}},{"id":159952,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/usgs_thumb.jpg"}],"country":"United States","state":"Nevada","otherGeospatial":"Battle Mountain-Eureka and Carlin trends","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"coordinates\": [\n          [\n            [\n              -115.9,\n              41.2\n            ],\n            [\n              -115.9,\n              39.525\n            ],\n            [\n              -117.217,\n              39.525\n            ],\n            [\n              -117.217,\n              41.2\n            ],\n            [\n              -115.9,\n              41.2\n            ]\n          ]\n        ],\n        \"type\": \"Polygon\"\n      }\n    }\n  ]\n}","edition":"Version 1.0","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4abbe4b07f02db672547","contributors":{"authors":[{"text":"Rodriguez, Brian D. 0000-0002-2263-611X brod@usgs.gov","orcid":"https://orcid.org/0000-0002-2263-611X","contributorId":836,"corporation":false,"usgs":true,"family":"Rodriguez","given":"Brian","email":"brod@usgs.gov","middleInitial":"D.","affiliations":[{"id":211,"text":"Crustal Geophysics and Geochemistry Science Center","active":true,"usgs":true}],"preferred":true,"id":205731,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Williams, Jackie M.","contributorId":11217,"corporation":false,"usgs":true,"family":"Williams","given":"Jackie","email":"","middleInitial":"M.","affiliations":[],"preferred":false,"id":205732,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

The study was conducted near the source area of the Chemical Spill-10 (CS-10) plume, a plume containing chlorinated solvents that underlies the MMR. Ground-water contamination near the source area extends from about 24 m (meters) to 35 m below land surface. The USANG designed two reactive-iron walls to be 12 m long and positioned 24 to 37 m below land surface to intersect and remediate part of the CS-10 plume.Because iron, as an electrical conductor, absorbs electromagnetic energy, the US Geological Survey used a cross-hole common-depth, radar scanning method to assess the continuity and to estimate the lateral and vertical extent of the two reactive-iron walls. The cross-hole radar surveys were conducted in boreholes on opposite sides of the iron injection zones using electric-dipole antennas with dominant center frequencies of 100 and 250 MHz. Significant decreases in the radar-pulse amplitudes observed in scans that traversed the injection zones were interpreted by comparing field data to results of two-dimensional finite-difference time-domain numerical models and laboratory-scale physical models.The numerical and physical models simulate a wall of perfectly conducting material embedded in saturated sand. Results from the numerical and physical models show that the amplitude of the radar pulse transmitted across the edge of a conductive wall is about 43 percent of the amplitude of a radar pulse transmitted across background material. The amplitude of a radar pulse transmitted through a hole in a conductive wall increases as the aperture of the hole increases. The modeling results indicate that holes with an aperture of less than 40 percent of the dominant wavelength of the radar pulse are not likely to be detected.Based on the results of the numerical and physical modeling, the decreases in radar-pulse amplitudes observed in scans traversing the injection zones are interpreted as electrically conductive zones that outline the distribution of iron. The area interpreted as iron in the northern A-wall contains two zones -- an upper zone about 10 m wide, extending from about 25 to 31 m below land surface, and a lower zone about 8 m wide, extending from 31.5 to 34.5 m below land surface. The area interpreted as iron in the southern B-wall is about 9 m wide, extending from about 27 to 34.5 m below land surface. No discrete holes were interpreted in either the A- or B-wall zones.The interpretation of the field data suggests that (1) the hydraulic-fracturing method introduced iron into the subsurface, but not in the dimensions originally proposed; (2) the iron within the treatment zones is distributed in a generally continuous manner; and (3) excluding the discontinuity in the A-wall, holes within the iron treatment zone, if any, exist at scales smaller than about 10 cm, the resolution limit of the radar antennas and acquisition geometry used for this study.
