Geochemistry of unconsolidated sediments in the US from the PLUTO database

This dataset contains geochemical data for unconsolidated sediments
(stream sediments, lake sediments, etc.) 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 sediment 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.
