This is version 2.0 of Tungsten Deposits in the United States. This data release provides the descriptions of approximately 100 U.S. sites that include mineral regions, mineral occurrences (deposits), and mine features that contain enrichments of tungsten (W). This data release reports on U.S. mines and deposits with greater than or equal to 215 metric tons of tungsten metal (30,000 short ton units of tungsten trioxide). Sites in this database occur in Alaska, Arizona, California, Colorado, Idaho, Montana, North Carolina, New Mexico, Nevada, Texas, Utah and Washington. As a part of the process set forth by Executive Order 13817, the USGS National Minerals Information Center (NMIC) identified W as a critical mineral...

Instrument, standard, and sample data from application of in situ laser ablation-inductively coupled plasma-mass spectrometry (LA-ICPMS) dating of scheelite in thin section, and sample data from isotope dilution thermal ionization mass spectrometry (ID-TIMS) scheelite dating are in this data release. Fractionation factor and ratio data in between NIST glass and natural scheelite as well as isotope dilution Sm-Nd scheelite data are also included. Scheelite is from two ore deposits within the Stibnite-Yellow Pine mining area, and analyses yielded bimodal U-Pb ages with major growth of scheelite in the range of 61.3 ± 4.1 to 55.1 ± 3.8 Ma and a second growth event involving both scheelite and stibnite at 45.8 ± 2.6...
These geospatial files are the essential components for the Geologic Map of the Stibnite Mining Area in Valley County, Idaho, which was published by the Idaho Geological Survey in 2022. Three main file types are in this dataset: geographic, geologic, and mining. Geographic files are map extent, lidar base, topographic contours, labels for contours, waterways, and roads. Geologic files are geologic map units, faults, structural lines meaning axial traces, structural points like bedding strike and dip locations, cross section lines, and drill core sample locations. Lastly, mining files are disturbed ground features including open pit polygons or outlines, and general mining features such as the location of an adit....
