Data

This U.S. Geological Survey (USGS) data release provides a digital geospatial database for the Geologic map of Precambrian rocks of the Sierra Madre, Carbon County, Wyoming, and Jackson and Routt Counties, Colorado (Houston and Graff, 1994). Attribute tables and geospatial features (points, lines and polygons) conform to the Geologic Map Schema (USGS NCGMP, 2020) and represent the...

Mine waste, including mill tailings, could host substantial critical mineral resources. Developing an understanding of the mineral hosts and occurrence of critical minerals in mine waste is essential to evaluating their resource potential. Volcanogenic massive sulfide (VMS) and sedimentary-exhalative (SEDEX) deposits are important global sources of copper, zinc, lead, gold, and silver...

This U.S. Geological Survey (USGS) data release contains data from stream water, groundwater/springs, and sediment samples collected from legacy mine land (LML) sites in central Colorado. The sites were selected using a GIS-based approach that integrated regional geological and geochemical datasets with known mine features and satellite data identifying hydrothermal alteration (ASTER) to...

This dataset consists of 529 areas of identified nickel laterite in southern Oregon and northern California, compiled in vector shapefile format from six historical publications from 1956 to 1983. Sources include state and federal projects for geologic mapping and critical mineral exploration purposes and are attributed to each polygon. Five original, georeferenced maps are included in...

Gravity data were collected in 2022-2024 to assist in mapping surface and subsurface geology in the Medicine Bow Mountains of southern Wyoming. This data release provides principal facts for 738 new gravity stations that were acquired to supplement existing public gravity data coverage.

This data release includes laser ablation inductively coupled plasma mass spectrometry (LA-ICPMS) U-Pb zircon geochronology data from four samples collected from rock units located in the Spinney Mountain Quadrangle and the Guffey NW Quadrangle in Park County, Colorado. Samples were collected from gniess and granite rocks, and age data was used to support publication of updated maps by...

This U.S. Geological Survey (USGS) data release provides a digital geospatial database for the geologic map of the eastern part of the Challis National Forest and vicinity, Idaho (Wilson and Skipp, 1994). Attribute tables and geospatial features (lines and polygons) conform to the Geologic Map Schema (USGS NCGMP, 2020) and represent the geologic map as published in U.S. Geological Survey...

This U.S. Geological Survey (USGS) data release updates the digital geospatial database for the southern portion of the geologic map of the western part of the Cut Bank 1 degree x 2 degrees quadrangle, northwestern Montana (Harrison and others, 1998). Attribute tables and geospatial features (points, lines, and polygons) conform to the Geologic Map Schema (USGS NCGMP, 2020). The 899,246...

This U.S. Geological Survey (USGS) data release accompanies planned publication ‘Geochemistry and radiogenic isotopes constrain the mantle source region of the Mountain Pass Intrusive Suite, California' and planned data release 'Whole-rock geochemical and isotopic data for the Mountain Pass Intrusive Suite, California'. The data release includes laser ablation multi-collector inductively...

Airborne electromagnetic (AEM) and magnetic survey data were collected during November 2017 over a total distance of 1,980 line kilometers in the southwestern San Joaquin Valley of California adjacent to the Elk Hills, North and South Coles Levee, and Buena Vista oil fields. These data were collected in support of groundwater salinity mapping and hydrogeologic framework development as...

Airborne electromagnetic (AEM) and magnetic survey data were collected during November 2018 over a total distance of 1,480 line kilometers in the Maricopa Flats and surrounding areas of southwestern San Joaquin Valley of California adjacent to the Buena Vista, Midway Sunset, Yowlumne, Los Lobos, Pioneer, Landslide, San Emidio Nose, Rio Viejo, and White Wolf oil fields. These data were...

This U.S. Geological Survey (USGS) data release accompanies planned publication ‘New constraints on location and timing of the Great Lakes tectonic zone, central Upper Peninsula, Michigan, USA. The data release includes laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) U-Pb zircon data and/or U-Pb apatite data for two samples from the Upper Peninsula, Michigan, USA...
