Data

This data release provides digital flight line data for a high-resolution airborne magnetic and radiometric survey over Virginia and North Carolina along and near the eastern U.S. 'Fall Zone', which represents the transitional area between Atlantic Coastal Plain sediments and Piedmont metamorphic and igneous rocks. The airborne data collection was funded by the U.S. Geological Survey (USGS) Earth

This dataset accompanies the proposed publication, 'Geochronology and geochemistry of igneous and metasedimentary rocks of northeast Afghanistan: A refinement of the timing and origin of crustal terranes', which focuses on refining the geochronology and geochemistry of these rocks during multiple time periods of accretion, regional metamorphism, and magmatic activity. The analyses were performed f

This data release provides access to an aeromagnetic survey and magnetization boundaries over Garlock, California and surrounding areas in southern California. The survey extends from the city of Bakersfield across the southern Sierra Nevada and Tehachapi Mountains and west over Indian Wells Valley and the towns of Mojave and Rosamond to just northwest of the town of Barstow. These data were acqui

HySpex by NEO (HySpex) VNIR-1800 and SWIR-384 imaging spectrometer radiance data were acquired on September 14, 2017 at the Cresson Pit of the Cripple Creek & Victor mine in Cripple Creek, Colorado. ASD FieldSpec® NG data were collected on September 13 and 14, 2017 at two calibration sites within the Cresson Pit imaged with the HySpex imaging spectrometers. The HySpex VNIR-1800 imaging spectromete

In response to Executive Order 13817 of December 20, 2017, the U.S. Geological Survey (USGS) coordinated with the Bureau of Land Management (BLM) to identify 36 nonfuel minerals or mineral materials considered critical to the economic and national security of the United States (U.S.) (https://pubs.usgs.gov/of/2018/1021/ofr20181021.pdf). Acquiring information on possible domestic sources of these c

This data release includes laser ablation inductively coupled plasma mass spectrometry (LA-ICPMS) U-Pb zircon geochronology data to determine the ages of Challis igneous rocks in the Thunder Mountain volcanic field and dikes west of the volcanic field, especially in and near the Stibnite-Yellow Pine mining district, ID. These efforts were made to help understand the stratigraphy and lithologic cha

Surface electrical resistivity tomography (ERT), time-domain electromagnetics (TEM), nuclear magnetic resonance (NMR), magnetics, and gravity data were acquired in 2016, 2017 and 2018 in the greater East River Watershed near Crested Butte Colorado with a focused effort in Redwell Basin. Five ERT profiles were acquired within Redwell Basin and Brush Creek to map geologic structure at depths up to 4

The data release for the geologic map of the Butte 1 degree x 2 degrees quadrangle, Montana, is a Geologic Map Schema (GeMS)-compliant version that updates the GIS files for the geologic map published in Montana Bureau of Mines and Geology Open File Report MBMG 363 (Lewis, 1998). The updated digital data present the attribute tables and geospatial features (points, lines and polygons) in the forma

This U.S. Geological Survey (USGS) data release presents a digital database of geospatially enabled vector layers and tabular data transcribed from the geologic map of the Lake Owen quadrangle, Albany County, Wyoming, which was originally published as U.S. Geological Survey Geologic Quadrangle Map GQ-1304 (Houston and Orback, 1976). The 7.5-minute Lake Owen quadrangle is located in southeastern Wy

This U.S. Geological Survey (USGS) data release provides the descriptions of the only U.S. sites-including mining districts, mineral occurrences, and mine features-that have reported production and (or) resources of indium (In). This dataset contains the Bingham and West Desert deposits in Utah, and the Chino site in New Mexico. Indium is considered a critical and strategic mineral because of its

These data include geochemical analyses of rock, mine waste, sediment, soil, and water samples collected from the Hajigak iron deposit, Bamyan and Wardak Provinces, Afghanistan in 2019.

This dataset includes TIFF (Tagged Image File Format) images of graphic drill core logs showing associated drill core information, a TIFF image of the explanation for the lithology and structure sections of the logs, an Esri shapefile of the locations of the drill holes, and 17 individual .csv files of tabular data that were compiled from handwritten drill core logs. The drill core is from the Mou
