Data

This data release provides Geologic Map Schema (GeMS)-compliant GIS data for new geologic mapping of the Bison Range and surrounding area on the Flathead Reservation, northwestern Montana. The database represents the geology for the 150 square kilometer, geologically complex map area, at a publication scale of 1:24,000. The map covers parts of Sanders and Lake Counties, Montana. All...

This data release provides digital flight line data for a high-resolution airborne magnetic and radiometric survey over parts of Montana in the vicinity of the Boulder Batholith. The airborne survey was funded by the Earth Mapping Resources Initiative and was designed to meet complementary needs related to geologic mapping and characterization of mineral resource potential. A total of 45...

This data release is a collection of quantitative and qualitative data for fluid inclusions in samples from the Bear Lodge alkaline complex, Wyoming. The dataset includes:microthermometry, Raman spectroscopy, noble gas spectroscopy, laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS), and energy dispersive X-ray analyses of fluid inclusions. For spatial context and...

This U.S. Geological Survey (USGS) data release provides a digital geospatial database for the geologic map of the central part of the Northern Park Range, Jackson and Routt Counties, Colorado (Snyder, 1980). Attribute tables and geospatial features (points, lines, and polygons) conform to the Geologic Map Schema (USGS NCGMP, 2020) and represent the geologic map as published in USGS...

This U.S. Geological Survey data release is a collection of Raman spectra, electron probe microanalytical results, and images for burbankite [(Na,Ca)3(Sr,Ba,Ce)3(CO3)5] from the type locality at the Rocky Boy stock, Bears Paw Mountains, Montana. Burbankite was described by Pecora and Kerr (1953) for the first time from samples collected in the Bears Paw Mountains (in their publication...

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...
