Geochemistry of stream sediments in the US from the NURE-HSSR database

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

Info
Geochemistry of water samples in the US from the NURE-HSSR database

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

Info
Results from the analysis of 723 stream-sediment samples from the Stikine Geophysical Survey area within the Petersburg, Sumdum, Bradfield Canal, and Sitka quadrangles, southeastern Alaska

Small regional scale geochemical mineral exploration results from field studies in Duncan Canal, Zarembo Island, and western Etolin Island.

Info
National Geochemical Database: Rock

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"

Info
Reanalysis of Selected Archived NURE-HSSR Sediment and Soil Samples from Arizona, California, Idaho, Montana, Nevada, New Mexico, and Utah (ver. 3.0, October 2018)

Reanalysis, using modern methods, of nearly 60,000 NURE-HSSR archived samples collected over parts of Arizona, California, Idaho, Montana, Nevada, New Mexico, and Utah.

Info
Reanalysis of Selected Archived NURE-HSSR Sediment and Soil Samples from Alaska

New analysis of existing samples from this area, to improve precision and accuracy and consistency of the measurements with those made on newly-collected samples. Data are provided in Microsoft Access, Microsoft Excel, CSV, and shapefile formats.

Info
Reanalysis of Additional Selected Archived NURE-HSSR Sediment Samples from Idaho and Montana

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.

Info
Geophysical and geochemical data from the area of the Pebble Cu-Au-Mo porphyry deposit, southwestern Alaska: Contributions to assessment techniques for concealed mineral resources

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.

Info
History and evaluation of national-scale geochemical data sets for the United States

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.

Info
Major- and trace-element concentrations in soils from two geochemical surveys (1972 and 2005) of the Denver, Colorado, metropolitan area

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.

Info
Geochemical data for samples collected in 2007 near the concealed Pebble porphyry Cu-Au-Mo deposit, southwest Alaska

Analytical results for geochemical samples collected in 2007 from the Pebble deposit and surrounding environs

Info
Geochemical data for samples collected in 2008 near the concealed Pebble porphyry Cu-Au-Mo deposit, southwest Alaska

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.

Info
Geochemical Data Release for Gospel-Hump Wilderness Area, Magruder Corridor and Special Mining Management Zone Additions to the Frank Church River of No Return Wilderness Area, and adjacent areas Idaho and Montana

Geochemical analyses of samples from stream sediments, magnetic heavy-mineral concentrates, nonmagnetic heavy-mineral concentrates, slightly magnetic to nonmagnetic heavy-mineral concentrates, and rocks. All were analyzed by semi-quantitative 6-step emission spectrography. Some of the stream sediment samples were also analyzed by flame-atomic absorption spectrophotometry. Data are provided in Microsoft Access format and as tab-delimited text.

Info
First steps of integrated spatial modeling of titanium, zirconium, and rare earth element resources within the Coastal Plain sediments of the southeastern United States

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.
