Older geochemical databases

Databases containing chemical analyses of sediments and soils that were conducted many years ago; some remain classical work held in high esteem for their time, but all are superseded by later compilations and more precise analytical methods.

Geochemical data [Show descriptions] [Hide descriptions]

Geochemistry of sediments in the US from the PLUTO database

Geochemical data for unconsolidated sediments (stream sediments, lake sediments, etc.) collected in the US and analyzed by the USGS. These data were originally entered in the PLUTO database, which is now merged into the National Geochemistry Database.

Geochemistry of soils in the US from the PLUTO database

Geochemical data for soils collected in the United States and analyzed by the USGS. The data were originally entered into the in-house PLUTO database. This is a subset of DDS-47.

Geochemistry of unconsolidated sediments in the US from the RASS database

Geochemical data for unconsolidated sediments (stream sediments, lake sediments, etc.) collected by USGS personnel and analyzed by USGS. These data were part of the Rock Analysis Storage System and are now merged into the National Geochemistry Database.

Geochemistry of soils in the US from the RASS database

Geochemical data for soils collected by USGS personnel and analyzed by USGS. These data were part of the Rock Analysis Storage System and are now merged into the National Geochemistry Database.

Geochemical landscape of the conterminous US: maps of NURE-HSSR data

Maps derived from a subset of the National Uranium Resource Evaluation Hydrogeochemical and Stream Sediment Reconnaissance data. Samples are from streams, lakes, ponds, springs, playas, and soils. Includes Na, Ti, Fe, Cu, Zn, As, Ce, Hf, Pb, Th, and U.

Chemical analyses of soils and other surficial materials of the conterminous US ("Shacklette" data)

Geochemistry of soils and other regoliths collected and analyzed by Hans Shacklette and colleagues from 1958 until about 1976.
