Carma San Juan Randall Laczniak David Wood 2007 1.0 vector digital data Geospatial data set for the USGS Mercury Core Library, Nevada NTS_BH_4sep07 Reston, Virginia U.S. Geological Survey https://water.usgs.gov/lookup/getspatial?ds297_NTS_BH_4sep07 Wood, David B. 2007 document U.S. Geological Survey Data Series 297 Henderson, Nevada U.S. Geological Survey In press https://pubs.usgs.gov/ds/2007/297 This geospatial data set represents about 2,500 locations of boreholes, shafts, tunnels, and drifts on and around the Nevada Test Site (NTS) where rock-samples have been collected. Information from the rock-samples is summarized for each hole and includes lithologic descriptions, physical and mechanical properties, fracture characteristics, and hydraulic properties where holes were completed below the water table. The digital data are accessed from the webpage for the NTS U.S. Geological Survey (USGS) Core Library and Data Center, Mercury, Nevada. Links to additional information, such as water-level data from the National Water Inventory System (NWIS), and USGS borehole graphical information are included for some holes. This geospatial data set was developed from information accessed from the USGS Mercury Core Library website to show the spatial distribution of holes having rock-sample information, and to summarize data compiled in separate files. Each hole has a summary of rock-sample information from 5 spreadsheets (rock samples, lithologic descriptions, rock properties, fracture characteristics, and hydraulic properties), and the total interval (depths) samples were obtained from. Additional links to USGS water-level charts and borehole graphics are provided where available. 2007 publication date Complete As needed -116.712560 -115.780318 37.350295 36.446911 American Geological Institute Glossary of Geology borehole core cutting core library drill core fracture charactistic geophysical log hydraulic property lithologic description rock property water level inlandWaters ISO 19115 Topic Category geoscientificInformation inlandWaters environment USGS Metadata Identifier USGS:f6e22ad6-bc97-461a-bb66-7d6fb00aec37 U.S. Board of Geographic Names (BGN) and Geographic Names Information System (GNIS) Mercury Nevada Nevada Test Site Nye County None Data have been checked to ensure the accuracy of the data.

Denver Colorado 80225 USA (303) 236-2450 (303) 236-1811 csanjuan@usgs.gov Spatial data sets supporting the USGS Mercury Core Library data bases were developed in cooperation with the U.S. Department of Energy (DOE) National Nuclear Security Administration/Nevada Site Office (NNSA/NSO) Underground Test Area (UGTA) project of the Office of Environmental Management, the NNSA/NSO Hydrologic Resource Management Program (HRMP), and the NNSA/NSO Maintenance of Test Capability (MTC) program. Microsoft Windows XP Version 5.1 (Build 2600) Service Pack 2; ESRI ArcCatalog 9.2.2.1350 Attribute information derived from the USGS Mercury Core Library spreadsheets, or by summarizing this information, reflect the accuracy of the original source data. These attributes were checked and evaluated as part of the review process associated with the publication of the source report (Larger Work Citation). Attributes added by the data set author were checked routinely by inspection using queries, hardcopy printouts, and visually using a GIS. Points represent the land-surface location of a hole (borehole, shaft, tunnel, or drift) where samples were collected. Coincident points typically represent the location of holes in close proximity, or a hole where samples are retrieved from distinct intervals and (or) depths. With the exception of holes having no latitude and longitude coordinates, all information available at the USGS Mercury Core Library on September 4, 2007 in the core- and cuttings sample spreadsheet; the lithologic-description spreadsheet; the rock-property spreadsheet; the fracture-characteristic spreadsheet; and the hydraulic-property spreadsheet were used to construct this geospatial data set. The accuracy of hole locations vary according to methods used to locate a well. Higher accuracy is associated with high-precision surveying methods, such as spirit level or differential global positioning system (GPS) surveying; and lower accuracy with coordinates determined solely on the basis of a given map. Codes depicting methods used to determine latitude and longitude coordinates are provided in source data spreadsheets. The depths of sample intervals are reported to an accuaracy of 0.1-feet.

Custom macros were developed by USGS staff to extract and summarize the type of information (core, lithologic, etc.) available, and the total interval sampled within each hole. The summarized information was then used to construct a geospatial layer in ArcGIS. New attribute fields containing hyperlinks to additional information not found in the Mercury Core Library, such as water level or borehole graphics, were added where appropriate.

Additonal links to water-level data available at the USGS Nevada website (http://nevada.usgs.gov/doe_nv/ ), and to USGS borehole graphic files were included. Each point feature has 20 attributes. Two attributes are automatically generated by the GIS (ObjectID, Shape) for internal software purposes. The remaining attributes were compiled from the source data or assigned by the authors to summarize data available for each hole. U.S. Geological Survey Michael Ierardi mailing
