Geophysical Characteristics of the Conterminous United States: Lithology - Physical Source Data

This workbook summarizes geophysical data for each lithology contained within the USGS Preliminary Integrated Geologic Map Databases for the United States (Open File Reports 2004-1355, 2005-1305, 2005-1323, 2005-1324, 2005-1325, 2005-1351, and 2006-1272). The geophysical attributes in the “Lith Summary” spreadsheet (tab) are measures of central tendency for all publically available measurements at the time of creation for 251 lithologies, reported as rock uniaxial compressive strength measured in megapascals (MPa) and hydraulic conductivity to water measured in micrometers/second. Further details on how data were summarized and sources for geochemical data are contained in the “ReadMe” spreadsheet (tab).
