Site-by-site information on 876 natural occurrences of asbestos reported within the conterminous US. Includes location, mineralogy, geology, and relevant literature for each asbestos site. Data are provided in Microsoft Excel, shapefile, and CSV formats.

Extensive core drilling has delineated a large, deep seated, structurally intact deposit here. Distribution of elements and minerals determined for this study provide a zoning model applicable to similar deposits and useful for resource exploration.

Audiomagnetotelluric (AMT) sounding data collected in 2008 in this area in support of assessments of concealed mineral resources.

Magnetotelluric sounding data collected in 2008 in this area to help USGS understand concealed mineral resources.

Includes all geochemical data generated by each project partnership funded through Earth MRI and will be updated periodically as additional geochemical data from these projects becomes available.

Digital flight-line aeromagnetic and aeroradiometric survey data over of the southeast Mojave Desert, parts of California and Nevada. Data files are provided in CSV as well as Geosoft binary database and grid exchange format (GXF).

Rock property measurements including density, magnetic susceptibility, and radiometric concentrations to understand structural and geophysical relationships associated with rare earth element mineral deposits. Data are provided in CSV format.

Airborne electromagnetic (AEM) and magnetic survey data along 1,637 line-km at a nominal flight height of 30m above terrain (averaging 53m), with nominal line spacing 1 km or 4 km. Data provided are minimally processed AEM and magnetic measurements, fully processed AEM data were used to develop an included resistivity model.

Data to determine the distribution of uranium deposits, breccia pipes, and collapse features and define areas permissible for uranium-bearing breccia pipes in northern Arizona and southeast Utah. Data are provided in shapefile format.

Laboratory reflectance and emissivity spectral measurements of dune sand samples collected from a variety of dune types and mineralogical compositions from eight dune field locations in Alaska, Arizona, California, Colorado, Idaho, Nevada and New Mexico. Data are provided in CSV format.

Data from 102 magnetotelluric (MT) stations collected from 2012 through 2014 in this area to improve regional conductivity models of the western United States.
