Geochemical analyses of samples to understand which methods best delineate known mineral deposits in this area. Data are provided in CSV and shapefile formats.

Chemical analyses for 46,955 samples collected in the Great Basin Tungsten assessment area, extracted from the USGS National Geochemical Database. Data are provided in Microsoft Access, Microsoft Excel, and tab-delimited text formats.

Chemical data from stream water, groundwater, and soil samples collected in 2019 and 2020 in this area. Data from a tracer study is included as tool for understanding sources and loading rates of metals affecting stream water quality in a watershed affected by legacy mining and natural sulfide-weathering. Data are provided in CSV format.

National-scale geochemical analysis of stream sediments and soils in the US collected and analyzed under the National Uranium Resource Evaluation program.

National-scale geochemical analysis of water samples in the US collected and analyzed under the National Uranium Resource Evaluation program.

Geochemical data for stratigraphic rock sequences containing dominantly fine-grained clastic rocks with appreciable organic carbon (above 0.5 weight percent), usually known as 'black shale facies examples' but including all fine-grained clastic rocks such as argillite, mudstone, claystone, and their low-medium grade metamorphic equivalents. Data are provide in Microsoft Access and tab-delimited text formats.

Geochemical data from selected USGS projects from the 1960s-1980s that were previously not published as digital data. Includes geochemical analyses from 36,498 samples of various types using analytical methods and instruments that were current when those studies were carried out. Data are provided in Microsoft Access, shapefile, and CSV formats.

Geochemistry of concentrates from the National Geochemical Database. Primarily inorganic elemental concentrations, most samples are from the continental US and Alaska.

Chemistry and geologic information for nearly 30,000 historic ore and ore-related rock samples from mineral deposits and mining districts in the United States. Data are provided in Microsoft Access and CSV formats.

Geochemical analysis of rock samples collected and analyzed by the USGS. This dataset includes and supersedes rock data formerly released as "Geochemistry of igneous rocks in the US extracted from the PLUTO database"

Geochemical analysis of sediment samples from the National Geochemical Database. Primarily inorganic elemental concentrations, most samples are of stream sediment in the continental US and Alaska.

Geochemical analysis of soil samples from the National Geochemical Database. Primarily inorganic elemental concentrations, most samples are from the continental US and Alaska.

National-scale geochemical analysis of stream sediments and soils in the US, from existing data, reanalysis of existing samples, and new sampling. Goal for sample density is one per 289 square km.

Reanalysis of existing samples provides more precise and accurate geochemical data because newer methods can be used. Stable isotopes of lead were also included. Data are provided in Microsoft Access, CSV, and shapefile formats.
