Study of the distribution of chemical elements and natural compounds on the earth and in the atmosphere and the chemical processes that affect the earth.
This category is also used for chemistry (Earth sciences).
A study conducted collected 57 surface rock samples from nine types of intrusive rock to reexamine the chemistry and metallic content of the major rock units of the Iron Hill complex
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.
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.
Geochemical data for soils collected by USGS personnel and analyzed by the USGS. These data were originally entered into the Rock Analysis Storage System (RASS), a database that is now merged into the National Geochemistry Database.
National-scale geochemical analysis of stream sediments and soils in the US collected and analyzed under the National Uranium Resource Evaluation program.
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.
Analyses to establish the background and baseline geochemistry for bedrock and soil in the region, and to determine terrestrial mercury sources and sinks in the park
