Data

This data release presents geologic map data for the surficial geology of the Blanding, Dove Creek, Cortez, and Bluff 30-minute by 60-minute quadrangles, Utah and Colorado. 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 provides digital flight line data for a high-resolution airborne magnetic and radiometric survey over much of the Upper Peninsula of Michigan and nearby parts of northern Wisconsin. The airborne survey was funded by the Earth Mapping Resources Initiative (Earth MRI). The survey was designed by the USGS in collaboration with the Michigan Geological Survey and contracted...

Surficial geologic mapping in Nebraska has been conducted primarily at the 1:24,000 scale since the mid-1990s, although there have also been limited efforts to map generalized Quaternary and surficial geology within the state and the region. We compiled and evaluated disparate maps (1:24,000 to 1:1,000,000) and datasets—including geologic, soil and soil parent material, and geomorphic...

This GeMS dataset depicts the age and type of geologic materials (rock or sediment) at or near the surface of Hollidaysburg, Pennsylvania and includes additional interpretive data pertaining to geological engineering properties in GeMS format.

This data release provides digital flight line data for a high-resolution airborne magnetic survey over the Cuyuna Iron Range in central Minnesota. The airborne survey was funded by the Earth Mapping Resources Initiative (Earth MRI). The survey was designed by the USGS in collaboration with the Minnesota Geological Survey, the University of Minnesota Natural Resources Research Institute...

    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...
