Data

The area of study is restricted to the northern Appalachian region between latitudes 38N and 48N and longitudes 66W and 77W in the U.S. states of Maine, New Hampshire, Vermont, New York, Massachusetts, Connecticut, Rhode Island, Pennsylvania, and Delaware. This study (Wintzer and others, 2025) integrates data from several sources, including geologic, geochemical, geophysical, watershed...

This project has inventoried and produced a digital database of Late Miocene through Holocene micropaleontologic slides and data available in the USGS collections along the lower Colorado River corridor, Imperial Valley, and Gulf of California. The digital database includes the location of samples, content of the samples, results of analyses, and other information in a format that can be...

NOAA’s Assessment Technical Support Unit (TSU) created a suite of temperature and precipitation metrics of extremes and threshold exceedance variables based on the Climate Model Intercomparison Program Phase 6 CMIP6 Localized Constructed Analogs (CMIP6-LOCA2) data set to support the Fifth National Climate Assessment (NCA5). Following the v20240915 revision of the CMIP6-LOCA2...

California’s wildfires are setting historic records for length, size, and severity (Safford and others, 2022, Kreider and others, 2024). These wildfires are altering soil processes like infiltration rates and carbon cycling over increasingly large areas (Staley and others, 2017; Kelly and others, 2020; Baur and others, 2024; Dow and others, 2024). In northern California, it is unclear...

Mineralized breccias at Hicks Dome, Illinois host abundant fluorspar, Pb-Zn sulfides, barite, rare earth elements (REE), and high field strength elements (HFSE). The REE+HFSE mineralogy of breccias between 600 and 900 meters were examined and mineral compositions were determined by electron probe microanalysis (EPMA), using a JEOL 8530F Plus field emission electron microprobe at the U.S

A terrain-based map of a large area of Franciscan Complex delineates varied areas of erosionally resistant topography and contrasting subdued topography distinguished using differences in the detailed shapes of individual topographic elements that in these rocks indicate relatively intact rock or mélange. Most of the line work in the map is based on interpretation of small-scale aerial...

This data release provides digital flight-line and gridded data for a high-resolution airborne magnetic and radiometric survey over a part of west central Utah. The survey was acquired as part of the UGSS Earth Mapping Resource Initiative (Earth MRI) to improve our understanding of the fundamental geologic framework of the region with applications to evaluating natural resources and...

This data release contains principal facts of gravity measurements by previous studies and collected by the U.S. Geological Survey in 1994-2023 and a compilation of existing and new density and magnetic susceptibility data in northeastern California. Gravity data are processed to isostatic anomalies using reduction densities of 2670 and 2200 kilogram/cubic meter. This region is at the...

The report titled "Field Trip to a Laramide Low-Angle Subduction Channel: Orocopia Schist in the Gavilan Hills, Southeasternmost California with Incidental Localities for Three Blue Minerals", which is associated with this Data Release, describes a one-day field trip to examine a latest Cretaceous subduction channel exposed in a readily accessible area of southeasternmost California, 40...
