The quadrangle is dominantly a complex terrane of greenschist- to amphibolitefacies metamorphic rocks that have been intruded by Mesozoic and Tertiary dioritic to granitic rocks and are overlain by Tertiary sedimentary and volcanic rocks. Serpentinized peridotite and associated greenstone, graywacke, and chert crop out in some places. \r\n\r\nThe quadrangle is bisected by the northeastward-trending Shaw Creek fault, which, on the basis of aeromagnetic interpretation and geologic data, is postulated to have left-lateral offset of as much as 48 km. On the northwest side of the Shaw Creek fault, metamorphic rock units have a northwesterly regional trend, and the oldest rocks could be Precambrian in age. Gneiss and schist in the southwestern part of the quadrangle are derived from both igneous and sedimentary protoliths, some of which may be as old as Precambrian. Other rock units, which include calcareous schist and thin-layered marble, black quartzite, semischist, and cataclastic rocks, are considered to be of probable Paleozoic age, although no fossils have yet been found in these rocks. Radiolarians and conodonts in chert associated with greenstone and ultramafic rocks indicate that the chert is of Permian age. \r\n\r\nPotassium-argon ages on igneous rocks of the Big Delta quadrangle fall into two groups: those with biotite, muscovite, hornblende, and sanidine ages between 50 to 69 m.y.; and those with biotite, hornblende, and sanidine ages between 88 to 105 m.y. The younger of these two groups appears to indicate the time of a plutonic event marked by intrusion of mostly small, isolated plutons, including hypabyssal stocks, and the eruption of silicic volcanic rocks. Most of the plutons are quartz monzonite to granite. \r\n\r\nThe older group of ages (88 to 105 m.y.) on igneous rocks includes ages on the largest plutons of the Yukono-Tanana Upland. The rocks range from diorite to quartz monzonite in composition. The potassium-argon ages on the metamorphic rocks of the Big Delta quadrangle, like those obtained elsewhere in the Yukon-Tanana Upland, appear to have been partly or completely reset by subsequent thermal events. \r\n\r\nVein and placer gold deposits have been mined in the Big Delta quadrangle, and although indications of mineralization are widespread, no other mineral deposits have yet been identified. The geologic, geochemical, and geophysical data are compatible with several types of deposits, including porphyry copper, massive sulfide, and skarn deposits. In certain aspects, the geology of the quadrangle is similar to areas in the eastern part of the Yukon-Tanana Upland and Canada where mineral deposits are known.","language":"English","publisher":"U.S. Geological Survey,","doi":"10.3133/cir783","usgsCitation":"Foster, H.L., Albert, N.R., Griscom, A., Hessin, T., Menzie, W., Turner, D.L., and Wilson, F.H., 1979, The Alaskan Mineral Resource Assessment Program: Background information to accompany folio of geologic and mineral resource maps of the Big Delta quadrangle, Alaska: U.S. Geological Survey Circular 783, iii, 19 p., https://doi.org/10.3133/cir783.","productDescription":"iii, 19 p.","costCenters":[{"id":114,"text":"Alaska Science Center","active":true,"usgs":true}],"links":[{"id":31342,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/circ/1979/0783/report.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":139243,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/circ/1979/0783/report-thumb.jpg"},{"id":391117,"rank":3,"type":{"id":36,"text":"NGMDB Index Page"},"url":"https://ngmdb.usgs.gov/Prodesc/proddesc_23992.htm"}],"country":"United States","state":"Alaska","otherGeospatial":"Big Delta quadrangle","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -147,\n              64\n            ],\n            [\n              -144,\n              64\n            ],\n            [\n              -144,\n              65\n            ],\n            [\n              -147,\n              65\n            ],\n            [\n              -147,\n              64\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4b06e4b07f02db69a276","contributors":{"authors":[{"text":"Foster, Helen Laura","contributorId":21936,"corporation":false,"usgs":true,"family":"Foster","given":"Helen","email":"","middleInitial":"Laura","affiliations":[],"preferred":false,"id":148472,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Albert, N.

Constituent concentrations, greatest during initial rainfall runoff, generally peaked midday of snowmelt runoff, corresponding with maximum melting and runoff. Instantaneous loads of constituents were largely a function of discharge. Days since last street sweeping or antecedent precipitation had no apparent effect; snowmelt-runoff loads apparently increased with number of days snow had been on the ground. Urban storm runoff may significantly contribute total ammonia nitrogen, total nonfiltrable residue, total copper, total iron, total lead, and total zinc; and snowmelt runoff may significantly contribute sodium and chloride, to local receiving waters. Data from two basins were used for calibration and verification of U.S. Environmental Protection Agency's Storm Water Management Model II for rainfall-runoff modeling of flow and total nitrogen. The model assumption that land-surface loads of total nitrogen are directly proportional to number of days prior to storm during which accumulated rainfall was less than 1.0 inch was not substantiated.

Sulfide minerals include pyrite, sphalerite, galena, and minor chalcopyrite, and galena-rich samples contain substantial amounts of silver. These minerals occur in a quartz-carbonate gangue along northeast-trending faults and fractures that exhibit (left?) lateral and vertical slip. The sense of fault movement and the northeasterly strike are consistent with predicted conjugate fault sets of the present San Andreas fault system. The sulfide mineralization is younger than the Franciscan rocks of Point Delgada and King Range, and it may have accompanied or postdated the inception of San Andreas faulting. Mineralization largely preceded uplift, the formation of a marine terrace, and the emplacement of landslide-related debris-flow breccias that overlie the mineralized rocks and truncate the sulfide veins. These field relations indicate that the sulfide mineralization and inception of San Andreas faulting were clearly more recent than the early Miocene and that the mineralization could be younger than about 1.2 m.y. \r\n\r\nThe sulfide veins at Point Delgada may be of economic significance. However, prior to any exploitation of the occurrence, economic and environmental conflicts of interest involving private land ownership, the Shelter Cove home development, and proximity of the coast must be resolved.","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/ofr79584","usgsCitation":"McLaughlin, R.J., Sorg, D.H., Ohlin, H., and Heropoulos, C., 1979, Base and precious metal occurrences along the San Andreas Fault, Point Delgada, California: U.S. Geological Survey Open-File Report 79-584, 11 p., https://doi.org/10.3133/ofr79584.","productDescription":"11 p.","costCenters":[{"id":312,"text":"Geology, Minerals, Energy, and Geophysics Science Center","active":true,"usgs":true}],"links":[{"id":408228,"rank":3,"type":{"id":36,"text":"NGMDB Index Page"},"url":"https://ngmdb.usgs.gov/Prodesc/proddesc_11319.htm","linkFileType":{"id":5,"text":"html"}},{"id":34309,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1979/0584/report.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":139555,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/1979/0584/report-thumb.jpg"}],"country":"United States","state":"California","otherGeospatial":"Point Delgada","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -124.082,\n              40.017\n            ],\n            [\n              -124.046,\n              40.017\n            ],\n            [\n              -124.046,\n              40.049\n            ],\n            [\n              -124.082,\n              40.049\n            ],\n            [\n              -124.082,\n              40.017\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a80e4b07f02db6492aa","contributors":{"authors":[{"text":"McLaughlin, Robert J. 0000-0002-4390-2288 rjmcl@usgs.gov","orcid":"https://orcid.org/0000-0002-4390-2288","contributorId":1428,"corporation":false,"usgs":true,"family":"McLaughlin","given":"Robert","email":"rjmcl@usgs.gov","middleInitial":"J.","affiliations":[{"id":312,"text":"Geology, Minerals, Energy, and Geophysics Science Center","active":true,"usgs":true}],"preferred":true,"id":153926,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Sorg, D.

Analyses for 70 elements in plants showed that, statistically, the concentration of 7 environmentally important elements, cadmium, chromium, fluorine, selenium, uranium, vanadium, and zinc, were related to emissions from phosphate-processing operations. Two additional elements, lithium and nickel, show probable relationships. The literature on the effects of these elements on plant and animal health is briefly surveyed. Relations between element content in plants and distance from the phosphate-processing operations were stronger at Soda Springs than at Pocatello and, in general, stronger in sagebrush than in the grasses. Analyses for 58 elements in soils showed that, statistically, beryllium, fluorine, iron, lead, lithium, potassium, rubidium, thorium, and zinc were related to emissions only at Pocatello and only in the A horizon. Moreover, six additional elements, copper, mercury, nickel, titanium, uranium, and vanadium, probably are similarly related along the same transect. The approximate amounts of elements added to the soils by the emissions are estimated. In C-horizon soils, no statistically significant relations were observed between element concentrations and distance from the processing sites. At Soda Springs, the nonuniformity of soils at the sampling locations may have obscured the relationship between soil-element content and emissions from phosphate processing.","language":"ENGLISH","publisher":"U.S. Govt.

The gossans, derived from sulfides, are ordinarily found at contacts between marble lenses and metavolcanic-metasedimentary rocks, but in the southern part of the mined area, gossans are also within marbles. The gossans are generally lensoidal and discontinuous along strike. The same type of metallization, in similar rocks, was found at the Hemair ancient workings, about 3 km southeast. Both deposits are thought to be of epigenetic origin, and ore deposition was controlled by shearing along marble contacts. Drilling is recommended at Farah Garan. \r\n\r\nAl Ashyab is 4 km south of Farah Garan, and similar rocks and structures extend through both areas but there are no ancient workings at Al Ashyab. The dominant geologic feature in the area is a high, narrow, light-colored ridge consisting of intensely silicified quartz porphyry. Pyritized metavolcanic rocks envelope the silicified rock, and geochemical sampling revealed weakly anomalous, erratically spaced concentrations of copper and zinc within these rocks. No further work is recommended for the area.\r\n\r\nQuartz-filled fractures containing gold were mapped at Al Asharfat, Lejourah, and other locations where ancient miners worked the veins. The gold-bearing quartz veins are narrow and have short strike lengths, and potential tonnages are thought to be small. The veins are in younger, more massive rocks than the enclosing metamorphic rocks and are thought to be younger than the adjacent sulfide deposits. No further work is recommended. \r\n\r\nPyritized zones and associated sparse copper oxides extend intermittently about 6 km south of Hemair in metasedimentary rocks of the Jiddah group. Similar zones, associated quartz vein swarms, and minor magnetite and gold are found in mafic metavolcanic rocks adjacent to the contact with quartz porphyry about 1 km west of Al Asharfat. Further study of these areas is recommended.","language":"ENGLISH","publisher":"U.S. Geological Survey,","doi":"10.3133/ofr791659","usgsCitation":"Smith, C.W., and Blank, H.R., 1979, Ancient mines of the Farah Garan area, southwestern Saudi Arabia: U.S. Geological Survey Open-File Report 79-1659, v, 56 p., [5] fold. leaves of plates :maps (2 fold. in pocket) ;28 cm.; (63 p., 7 over-size sheets - PGS), https://doi.org/10.3133/ofr791659.","productDescription":"v, 56 p., [5] fold. leaves of plates :maps (2 fold. in pocket) ;28 cm.; (63 p., 7 over-size sheets - PGS)","costCenters":[],"links":[{"id":144476,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/1979/1659/report-thumb.jpg"},{"id":38966,"rank":400,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/1979/1659/plate-1.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":38967,"rank":401,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/1979/1659/plate-2.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":38968,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1979/1659/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4ac8e4b07f02db67c295","contributors":{"authors":[{"text":"Smith, C.

The holes were drilled on a hexagonal pattern over an area about 50 m wide and 150 m long to obtain detailed information on environment of deposition and distribution of anomalous amounts of copper sulfides visible in outcrop, as well as to obtain samples for study of the geochemistry, isotope geology, mineralogy, and physical properties of the rocks and sulfide occurrences. Preliminary megascopic examination of the cores suggests that the purple and green colors represent original oxidizing and reducing environments of deposition on a relatively stable tidal flat and shallow shelf. Two of the five green beds contain zones of copper sulfides, largely bornite and chalcocite with trace amounts of chalcopyrite and covellite. The zones vary somewhat in thickness and stratigraphic position within the mineralized green beds. This report covers only the preliminary results of the ongoing multiple intensive studies of the drilling site and cores. These studies are part of an attempt to develop a model for green-bed copper- silver occurrences in Belt rocks of Proterozoic age. The model is needed to aid appraisal of the mineral potential of these mineral occurrences that are common in much of the 120,000 km2 of Belt terrane.","language":"ENGLISH","publisher":"U.S. Geological Survey,","doi":"10.3133/ofr79938","usgsCitation":"Harrison, J.E., and Reynolds, M.W., 1979, Preliminary geology of the Blacktail Mountain drilling site, Flathead County, Montana: U.S. Geological Survey Open-File Report 79-938, ii, 36 p., 1 over-size sheet :ill. ;28 cm., https://doi.org/10.3133/ofr79938.","productDescription":"ii, 36 p., 1 over-size sheet :ill. ;28 cm.","costCenters":[],"links":[{"id":151425,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/1979/0938/report-thumb.jpg"},{"id":48708,"rank":400,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/1979/0938/plate-1.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":48709,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1979/0938/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4abce4b07f02db673698","contributors":{"authors":[{"text":"Harrison, Jack Edward","contributorId":49778,"corporation":false,"usgs":true,"family":"Harrison","given":"Jack","email":"","middleInitial":"Edward","affiliations":[],"preferred":false,"id":180558,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Reynolds, Mitchell W. 0000-0002-9966-3896 mwreynol@usgs.gov","orcid":"https://orcid.org/0000-0002-9966-3896","contributorId":4641,"corporation":false,"usgs":true,"family":"Reynolds","given":"Mitchell","email":"mwreynol@usgs.gov","middleInitial":"W.","affiliations":[{"id":318,"text":"Geosciences and Environmental Change Science Center","active":true,"usgs":true}],"preferred":true,"id":180557,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

Detection of altered rocks from Landsat is based on the distinctive spectral reflectance of limonite present at coatings on weathered surfaces Some altered rocks are visible as bleached areas in individual MSS bands; however, they cannot be consistently distinguished from unaltered rocks with high albedo nor from bright areas resulting .from topographic slope. Black-and-white ratio images were generated to subdue .topographic effects, and three ratio images were composited in color to portray spectral radiance differences, forming an image known as a color-ratio composite (CRC). The optimum CRC image for this area has MSS 4/5 as blue, MSS 4/6 as yellow, and MSS 6/7 as magenta, and differs in two respects from most CRC images of arid areas. First, as a result of the increased vegetation cover in the study area, MSS 5/6 was replaced by MSS 4/6 as the yellow layer. Second, 70 mm positive transparencies were replaced by large format images (64 cm), thereby improving the internal registration of the CRC image and the effective spatial resolution. The pattern of limonitic rocks depicted in the CRC closely agrees with the mapped pattern of the alteration zones at the Copper Canyon and Copper Basin porphyry copper deposits. Certain west-facing topographic slopes in the altered areas are depicted as unaltered in the CRC, apparently due to atmospheric scattering, and illustrate the need for atmospheric correction. The disseminated gold deposits at Gold Acres and Tenabo are poorly represented in the CRC because of the general absence of limonite on these deposits. The presence of unaltered limonitic sedimentary and volcanic rocks is the largest obstacle to discriminating altered areas within the mineral belt. Reflectance spectra, made in situ and in the laboratory indicate differences between altered and unaltered rocks in the Spectra region between 1.1 ?m and 2.5 ?m. Such differences may be detectable by a remote scanner with a longer wavelength range than current Landsat MSS (0.6 ?m-1.1 ?m).","language":"ENGLISH","publisher":"U.S. Geological Survey,","doi":"10.3133/ofr78585","usgsCitation":"Krohn, M.D., Abrams, M.J., and Rowan, L.C., 1978, Discrimination of hydrothermally altered rocks along the Battle Mountain-Eureka, Nevada, mineral belt using Landsat images: U.S. Geological Survey Open-File Report 78-585, v, 66 leaves :ill., maps, photos ;28 cm.; (84 p. - PGS), https://doi.org/10.3133/ofr78585.","productDescription":"v, 66 leaves :ill., maps, photos ;28 cm.; (84 p. - PGS)","costCenters":[],"links":[{"id":141211,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/1978/0585/report-thumb.jpg"},{"id":37690,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1978/0585/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4b24e4b07f02db6ae85c","contributors":{"authors":[{"text":"Krohn, M.
