The compilation contributes to the U.S. Department of Energy's Yucca Mountain Project, established to determine whether or not the Yucca Mountain Site is suitable for the disposal of high-level nuclear waste. Studies of local and regional faulting and earthquake activity, including the features depicted on the accompanying map, are carried out to help characterize seismic hazard and tectonic processes that may be relevant to the future stability of Yucca Mountain. The Yucca Mountain site lies in the central part of the Beatty 30' by 60' quadrangle and is centered approximately 15 km south of the south edge of the Pahute Mesa quadrangle. Purpose: To provide to the public a digital geologic map database of the faults, lineaments, and earthquake epicenters of the Pahute Mesa 30' X 60' quadrangle, Nevada Time_Period_of_Content: Time_Period_Information: Single_Date/Time: Calendar_Date: 1996 Currentness_Reference: publication date Status: Progress: complete Maintenance_and_Update_Frequency: none planned Spatial_Domain: Bounding_Coordinates: West_Bounding_Coordinate: -117.0 East_Bounding_Coordinate: -116.0 North_Bounding_Coordinate: 37.5 South_Bounding_Coordinate: 37.0 Keywords: Theme: Theme_Keyword_Thesaurus: USGS Thesaurus Theme_Keyword: geology Theme_Keyword: geologic maps Theme_Keyword: bedrock geologic units Theme_Keyword: geologic structure Theme_Keyword: earthquake occurrences Theme_Keyword: geospatial datasets Theme: Theme_Keyword_Thesaurus: National Geologic Map Database Catalog themes, augmented Theme_Keyword: 3100 - Vector Theme_Keyword: 3110 - ESRI Theme_Keyword: 3112 - export Theme_Keyword: 1100 - Geology Theme_Keyword: 1101 - General Theme_Keyword: 3120 - Generate Theme: Theme_Keyword_Thesaurus: ISO 19115 Topic Categories Theme_Keyword: geoscientificInformation Place: Place_Keyword_Thesaurus: Augmented FIPS 10-4 and FIPS 6-4 Place_Keyword: f32023 = Nye Access_Constraints: none Use_Constraints: none Point_of_Contact: Contact_Information: Contact_Person_Primary: Contact_Person: Minor, Scott A Contact_Organization: USGS-GEO-CRG-ESP Contact_Address: Address_Type: mailing and physical address Address: Mail Stop 913, USGS Box 25046, Denver Federal Center City: Denver State_or_Province: CO Postal_Code: 80225-0046 Country: US Contact_Voice_Telephone: 303-236-0303 Contact_Electronic_Mail_Address: sminor@usgs.gov Data_Set_Credit: D.S. Aitken, S.C. Harmsen, Paia Levine, T.M. McCulloch, D.A. Ponce and J.C. Shulters provided invaluable computer and other technical assistance in compiling an earlier preliminary version of this map. H.R. Covington generously provided unpublished fault data and identified faults that have moved in response to recent nuclear weapons testing. M.C. Reheis and K.M. Haller kindly supplied stable-base copies of their published lineament and fault map data, respectively, which allowed for hand digitization of the data by M.F. Duncan. David Vonseggern (Univ. of Nevada, Reno) provided invaluable digital catalogs of historical and SGBSN earthquake events. This compilation benefited significantly from discussions with H.R. Covington, S.C. Harmsen, M.E. Meremonte and P.P. Orkild. We gratefully acknowledge improvements to the map resulting from critical reviews by R.E. Anderson, C.G. Bufe, H.R. Covington, D.W. O Leary, and M.W. Reynolds. Data_Quality_Information: Logical_Consistency_Report: Most of the faults shown on this map are depicted on the previously released, 1:100,000- scale digital geologic compilations of the Pahute Mesa quadrangle (Minor and others, 1993) and the Nevada Test Site (NTS) area (Sawyer and others, 1995). Lineaments shown on this compilation were initially mapped by Reheis (1992) at a scale of 1:100,000 from aerial photographs to help identify and characterize potentially active faults near Yucca Mountain. This compilation shows epicenters for earthquakes occurring in the Pahute Mesa 30' by 60' quadrangle from 1868 through December, 1994. Seismicity data for the period 1868 to August 1978 were derived from a historical catalog of southern Great Basin earthquakes compiled by Meremonte and Rogers (1987). Completeness_Report: Complete Lineage: Process_Step: Process_Description: Details and significance of fault, lineament, and seismicity data used in the current compilation are described in following sections. Each type of data was digitized differently: (1) most fault data were imported from previous 1:100,000-scale digital geologic compilations covering the Pahute Mesa quadrangle (Minor and others, 1993; Sawyer and others, 1995); (2) a few supplemental (newly acquired) fault lines were hand digitized within the GIS program indicated below; (3) selected lineaments originally mapped by Reheis (1992) were hand digitized using GSMAP (Selner and Taylor, 1993); and (4) seismicity data point coordinates were read directly from ASCII tables modified from reported seismicity catalogs (Meremonte and Rogers, 1987; D. Vonseggern, Univ. of Nevada, Reno, digital commun., 1995). A non-edited digital base map of the Pahute Mesa 30’ x 60 quadrangle, which is included with the data files, was obtained by scanning and vectorizing a stable-base copy of the published U.S. Geological Survey 1:100,000-scale base map. Geographic Resource Analysis Support System (GRASS), a public domain GIS developed by the U.S. Army Corps of Engineers, was used to transform all new component data to Universal Transverse Mercator projections, merge data in the appropriate map layers, hand digitize supplemental line data, conduct final editing and modification of map elements, and assign attributes to map line elements. Finally, GRASS was used to convert the data layers to ARC/INFO ASCII and export files.
