This dataset contains geochemical data for soils collected in the United States and analyzed in the analytical laboratories of the Geologic Division of the U.S. Geological Survey (USGS). These data represent analyses of soil samples collected in support of various USGS programs. The data were originally entered into the in-house PLUTO database which was used by the Geologic Division from the mid- 1970's through the mid-1990's to archive geochemical data. A portion of the PLUTO data base is published as: Baedecker, P.A., Grossman, J.N., and Buttleman, K.P., 1998, National Geochemical Data base: PLUTO geochemical data base for the United States: U.S. Geological Survey Digital Data Series DDS-47. The data presented here are derived from DDS-47.
