In December of 2018, the U.S. Geological Survey (USGS) signed a Technical Assistance Agreement with a third party to reanalyze 2,324 archived sample splits collected as part of the National Uranium Resource Evaluation (NURE) Hydrogeochemical and Stream Sediment Reconnaissance (HSSR) project from selected areas in Idaho and Montana. A small amount (approximately 0.25 grams [g]) of sieved <75-micron sample material was retrieved from the USGS National Geochemical Sample Archive for geochemical analysis. These samples were analyzed for 48 elements by ALS Global laboratories using their ultra-trace four-acid-digestion dual-mode inductively coupled plasma mass spectrometry (ICPMS) (ALS ME-MS61L) method (Ag, Al, As, Ba,...

The geochemical data included here were generated as part of a Technical Assistance Agreement between the U.S. Geological Survey (USGS) and Rio Tinto Exploration based in Salt Lake City, Utah. Beginning in November of 2015, we began a project to reanalyze up to 60,000 archived sample splits originally collected as part of the National Uranium Resource Evaluation (NURE) Hydrogeochemical and Stream Sediment Reconnaissance (HSSR) project from selected areas in Arizona, California, Idaho, Montana, Nevada, New Mexico, and Utah. A small amount (approximately 0.25 g) of sieved <75 micron sample material was retrieved from the USGS National Geochemical Sample Archive for geochemical analysis. These samples were analyzed...

Selected archived sample splits collected as part of the National Uranium Resource Evaluation (NURE) Hydrogeochemical and Stream Sediment Reconnaissance (HSSR) program, were reanalyzed by the U.S. Geological Survey (USGS) as part of a NURE-HSSR Reanalysis project (Smith and others, 2018). A small amount (approximately 0.25 grams [g]) of sieved less than 75-micron sample material was retrieved from the USGS National Geochemical Sample Archive for geochemical analysis. These samples were analyzed for 51 elements under a Technical Assistance Agreement with a third party by ALS Global laboratories using their ultra-trace four-acid-digestion dual-mode inductively coupled plasma-optical emission spectrometry/mass spectrometry...

The data release for Gospel-Hump Wilderness Area and the Magruder Corridor and Special Mining Management Zone Additions to the Frank Church River of No Return Wilderness Area, and adjacent areas Idaho and Montana, contains a subset of previously unpublished geochemical data from the 1979-1984 projects. In the case of Gospel-Hump Wilderness Area study (Lund and Esparza, 1990), the purpose of the project was to determine petrologic and geochemical characteristics and to investigate effects of historic mine drainage in the study area. Data for the Magruder Corridor Addition reflect rock geochemistry to document petrologic and geochemical characteristics (Mosier and others, 1981; Lund and others, 1992). Included in...

This data release contains geochemical data from selected U.S. Geological Survey (USGS) projects from the 1960s-1980s that were previously unpublished as digital data. The objective of those projects was to describe the geology, determine petrologic and geochemical characteristics, or to evaluate the mineral resource potential of Federal Lands and adjacent study areas. These data comprise geochemical analyses from 36,498 samples--27,223 rock samples, 4,091 sediment samples, 2,351 soil samples, 330 heavy-mineral pan concentrate samples, 297 organic material samples, 58 mineral samples, 27 water samples, 11 miscellaneous samples, and 2,110 unspecified media samples. More than 78 percent of these samples were analyzed...
