Data

    This data release presents geologic map data for the surficial geology of the Wheeler Peak, Raton, Springer, and Taos 30-minute by 60-minute quadrangles, New Mexico. This 1:100,000 scale geologic mapping incorporates new interpretive contributions and compilation from 1:24,000 to 1:250,000 scale published geologic map data sources. Much of the geology incorporated from previous...

This data release presents U-Pb LA-ICP-MS ages for eight volcanic and plutonic rocks located in the Wallace and Sandpoint 1° x 2° quadrangle region of in northern Idaho and northwestern Montana. The samples were collected by Jeffery L. Mauk and Micah A. Hernandez in 2021 and were analyzed via LA-ICP-MS in 2023 in the Denver Radioisotope Lab. The weighted mean age from all concordant...

The Emmons Lake volcanic center is a spatially clustered group of stratovolcanoes and calderas on the Alaska Peninsula near Cold Bay, Alaska. The volcanic center is characterized by several ice- and snow-clad stratovolcanoes located within and along the margins of a nested-caldera complex that includes Emmons Lake. A shieldlike ancestral edifice (ancestral Mount Emmons) is truncated by...

Much of the southeastern United States, including all of Florida, is covered by flat-lying sedimentary strata of the Atlantic and Gulf Coastal Plains which have accumulated since Middle Jurassic time. The pre-Middle Jurassic rocks that underlie these coastal plains in Florida, here collectively referred to as “basement,” are known only from a relatively small number of boreholes. This...

This data release provides digital flight line data for a high-resolution airborne magnetic and radiometric survey over the Laramie Mountains region of Wyoming. The airborne survey was funded by the Earth Mapping Resources Initiative (Earth MRI). The survey was designed by the USGS in collaboration with the Wyoming State Geological Survey and contracted by the USGS. The survey was...

This data release provides a Geologic Map Schema (GeMS, USGS NCGMP, 2020) version of the State Geologic Map Compilation (SGMC) geodatabase of the conterminous United States (Horton and others, 2017). The SGMC provides spatial data for 48 state geologic maps that range from 1:50,000 to 1:1,000,000 scale. The GeMS version of the SGMC provides updated data for Arkansas, Mississippi...

This U.S. Geological Survey (USGS) data release provides a digital geospatial database for the preliminary geologic map of the Greeley 1 degree x 2 degrees quadrangle, Colorado and Wyoming (Braddock and Cole, 1978). 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...

This U.S. Geological Survey (USGS) data release provides a digital geospatial database for the geologic map of the mineral resource potential of the Savage Run Wilderness, Carbon and Albany Counties, Wyoming (McCallum and Kluender, 1983). Attribute tables and geospatial features (points, lines and polygons) conform to the Geologic Map Schema (USGS NCGMP, 2020) and represent the geologic...

This file geodatabase contains a GeMS-compliant 1:24,000-scale digital geologic map of The Geysers geothermal field and surrounding region in the northern California Coast Ranges and the Mayacamas Mountains. The database includes geologic map unit polygons, contacts, faults, geologic linework, structural orientation data, overlays, and supporting tables such as DataSources...

This U.S. Geological Survey (USGS) data release provides a digital geospatial database for the geologic map of the Craig 1 degree x 2 degrees quadrangle, northwestern Colorado (Tweto, 1976). 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 the USGS Miscellaneous...

This U.S. Geological Survey (USGS) data release provides a digital geospatial database for the geologic map of the central Pioneer Mountains, Blaine and Custer counties, central Idaho (Dover, 1983). 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 Miscellaneous

This U.S. Geological Survey (USGS) data release provides a digital geospatial database for the geologic map of the northernmost Park Range and southernmost Sierra Madre, 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...
