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

This workbook summarizes nutrient geochemical 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 geochemical attributes in the “Lith Summary” spreadsheet (tab) are measures of central tendency for all whole rock analyses publically available at the time of creation for 284 lithologies, reported as percent sulfur and nitrogen. Further details on how data were summarized and sources for geochemical data are contained in the “ReadMe” spreadsheet (tab).
