Precambrian rocks are biotite gneiss, the Boulder Creek Granodiorite, granophyre dikes, and quartz veins. The Boulder Creek intrudes the biotite gneiss, and both of these units are cut by north-northwest-trending granophyre dikes and quartz veins. Biotite gneiss contains structure elements of a northwest and a northeast fold system. Lineations and foliations in the Boulder Creek are generally concordant to the northeast fold system . of the gneiss. \r\n\r\nLate Paleozoic to Mesozoic and Mesozoic sedimentary formations, in ascending order and with their approximate thicknesses, are the State Bridge Formation, 15 feet; the Chinle and Chugwater Formations undivided, 0-95 feet; the Sundance Formation, 0?-100 feet; the Morrison Formation, 250 feet; the Dakota Sandstone, 225 feet; the Benton Shale, 340 feet; the Niobrara Formation, 600 feet; and the Pierre Shale. Quaternary deposits are terrace, landslide, and modern flood-plain deposits. \r\n\r\nLaramide rock deformation is related to the Park Range uplift and includes faulting and, in the sediments, some folding. Some of the faults, including the regional Gore fault, are Precambrian structures reactivated in Laramide time.","language":"ENGLISH","publisher":"U.S. Geological Survey],","doi":"10.3133/ofr683","usgsCitation":"Barclay, C.V., 1968, Geology of the Gore Canyon-Kremmling area, Grand County, Colorado: U.S. Geological Survey Open-File Report 68-3, 187 p. ill., maps (some col.) ;29 cm., https://doi.org/10.3133/ofr683.","productDescription":"187 p. ill., maps (some col.) ;29 cm.","costCenters":[],"links":[{"id":145875,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/1968/0003/report-thumb.jpg"},{"id":40791,"rank":400,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/1968/0003/plate-1.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":40792,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1968/0003/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4ac9e4b07f02db67c8f8","contributors":{"authors":[{"text":"Barclay, C.S.

A secondary purpose was to provide an adequate evaluation and calibration of airborne and ground-based instruments used in the survey.\r\n \r\nPisgah Crater and its vicinity was chosen as one of the fundamental test sites for the NASA remote sensing program because of its relatively fresh basaltic flows and pyroclastics. Its typical exposure of basalt also made it a possible lunar analogue. A fundamental test site for the purpose of the program is defined as a readily accessible area for which the topography, geology, hydrology, soils, vegetation and other features are relatively well known. All remote sensor instrument teams, i.e. infrared, radar, microwave, and photography, were obligated to use the fundamental test sites for instrument evaluation and to establish terrain identification procedures. \r\n\r\nPisgah Crater, nearby Sunshine Cone, and their associated lava flows are in the southern Mojave Desert about 40 miles east-southeast of Barstow, California. (See fig. 1.) U. S. Highway 66 skirts .the northern part of the area and provides access via asphalt-paved and dirt roads to the Crater and to the perimeters of the flows. Pisgah Crater, which is a pumiceous cone, is owned and occasionally quarried by the Atchison, Topeka and Santa Fe Railroad. The remaining part of the area to the south is within the boundary of the Marine Corps Base, Twentynine Palms, California and is currently being used as a gunnery, and bombing range. The proximate area to east, west, and north of Pisgah Crater is public domain. \r\n\r\nOriginally, an area totaling 10 square miles was outlined for detailed study. (See plate 1.) This included an 8 mile long strip extending south- east from and including Pisgah Crater to Lavic Dry Lake, and a 2 mile strip aligned to include a portion of the Sunshine lava flow and the dry lake. Additional aerial infrared imagery of the Sunshine and Pisgah flows along the Pisgah fault proved so interesting and informative that this area is included in the discussion. \r\n\r\nInfrared surveys were flown February ii through 13, 1965 and August 5 and 9, 1966. The initial survey was flown by the NASA personnel aboard the NASA 926 Convair 240 aircraft. Because of technical problems with the infrared scanners (4.5-5.5 and 8-14 micron bands) and with certain ground instruments, most of the imagery and ground temperature data obtained during the initial survey period was of little value. However, excellent infrared imagery in the 8-14 micron (?) region of the spectrum was acquired by the Geological Survey during the August 1966 survey. The scanner was mounted in a Beech D-18 aircraft provided by the Survey's Water Resources Division. Likewise, more reliable ground data was obtained at this time owing to improved instrumentation and technique. Ground data were taken by Geological Survey personnel including W. A. Fischer, J. D. Friedman, W. R. Hemphill, D. L. Daniels, G. R. Boynton, Po W. Philbin and the author. C. R. Fross operated the infrared scanner during the August, 1966 survey and R. M. Turner was-responsible for photo processing of the infrared imagery. Their assistance is gratefully acknowledged.","language":"ENGLISH","publisher":"U.S. Geological Survey],","doi":"10.3133/ofr69104","usgsCitation":"Gawarecki, S.J., 1968, Infrared survey of the Pisgah Crater area, San Bernardino County, California - a geologic interpretation: U.S. Geological Survey Open-File Report 69-104, 49 p. :maps ;29 cm., https://doi.org/10.3133/ofr69104.","productDescription":"49 p. :maps ;29 cm.","costCenters":[],"links":[{"id":147296,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/1969/0104/report-thumb.jpg"},{"id":42312,"rank":400,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/1969/0104/plate-1.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":42313,"rank":401,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/1969/0104/plate-2.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":42314,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1969/0104/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4ab0e4b07f02db66daf1","contributors":{"authors":[{"text":"Gawarecki, Stephen J.","contributorId":52189,"corporation":false,"usgs":true,"family":"Gawarecki","given":"Stephen","email":"","middleInitial":"J.","affiliations":[],"preferred":false,"id":168313,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

Channel samples across some of these altered zones have produced anomalous gold values over widths which merit further investigation as potential large tonnage low-grade gold deposits.\r\n\r\nTrace gold gradients have also been detected in the wall rocks adjacent to mineralized veins and in hydrothermal alteration zones in the Pedro Dome-Cleary Summit area. Although most of the gradients may not materially increase the mineable width of the deposit under current economic conditions, such gradients can be used to locate auriferous quartz veins and altered zones by geochemical methods. Gold enrichment is accompanied by anomalous concentrations of arsenic and antimony, and gold bearing quartz veins and altered zones are frequently signaled by peripheral haloes of these metals before trace gold is detectable. Hydrothermally altered and/or sheared zones in both granitic and metamorphic rocks should be carefully prospected, along the trend of the Cleary Antiform.","language":"ENGLISH","publisher":"U.S. Geological Survey],","doi":"10.3133/ofr68101","usgsCitation":"Forbes, R., Pilkington, H., and Hawkins, D.B., 1968, Gold gradients and anomalies in the Pedro Dome-Cleary Summit area, Fairbanks district, Alaska: U.S. Geological Survey Open-File Report 68-101, 49 p. ill., maps ;27 cm., https://doi.org/10.3133/ofr68101.","productDescription":"49 p. ill., maps ;27 cm.","costCenters":[],"links":[{"id":147255,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/1968/0101/report-thumb.jpg"},{"id":42164,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1968/0101/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4abde4b07f02db6741ef","contributors":{"authors":[{"text":"Forbes, Robert B.","contributorId":48984,"corporation":false,"usgs":true,"family":"Forbes","given":"Robert B.","affiliations":[],"preferred":false,"id":168154,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Pilkington, H.D.","contributorId":77942,"corporation":false,"usgs":true,"family":"Pilkington","given":"H.D.","email":"","affiliations":[],"preferred":false,"id":168155,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Hawkins, D.
