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.
Small regional scale geochemical mineral exploration results from field studies in Duncan Canal, Zarembo Island, and western Etolin Island.
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"
Uninterpreted geophysical measurements and geochemical and mineralogical analytical data from samples collected during the summer field seasons from 2007 to 2010. Data are available in a single Geographic Information System (GIS) database.
Overview explaining how and why six different geochemical data sets were produced, and why you might choose to use the data in any one of these instead of the others.
Analyses of about 900 samples by ICP-MS, ICP-AES, and hydride generation-atomic absorption spectrometry. The samples collected in 2005 were also analyzed by a cold vapor-atomic absorption method for mercury.
Analytical results for geochemical samples collected in 2007 from the Pebble deposit and surrounding environs
Chemical analysis of surface samples taken over a well known but concealed deposit to understand metal migration into the surface materials and to assess the power of surface sampling for detecting concealed deposits of this type.
This report summarizes the assembly of pertinent data, determination of its limits, analysis of its properties, and the relations among the different data types in preparation for future modeling.
