Data

We report rock and mineral K-Ar isotopic dates from 55 Cenozoic rocks and 49 pre-Cenozoic rocks from the eastern Mojave Desert in southeastern California, Nevada, and Arizona and 3 pre-Cenozoic rocks from the southern Sierra Nevada, California. For many of the samples two separate minerals were dated. We also report Ar-Ar dates from 7 pre-Cenozoic rocks in the eastern Mojave Desert.

This data release contains three comma separated value (.csv) tables describing data from alluvial cobbles collected from a Pleistocene alluvial deposit on the noerth side of Poncha Pass, near Salida, Colorado. Tables "DryUnion_Burial_Isochron_Aluminum26_Cyr.csv" and "DryUnion_Burial_Isochron_Beryllium10_Cyr.csv" contain aluminum-26 and beryllium-10 data, respectively, for samples...

This is a data release of a .csv file that provides measurements of structural features in the Grand Canyon region. These data document structural attitudes, used to describe the orientations of geologic features in three dimensions. Included fields describe the type of geologic feature mentioned, the azimuth and inclination of the measurement (for planar data these correspond to the...

This data release presents point data associated with studies to understand the crustal structure of the 2019 Ridgecrest earthquakes epicentral region and the interaction of the northeast-to-east-striking Garlock fault with the northwest-striking faults of the Eastern California Shear Zone and Walker Lane. Data include principal fact information for new gravity measurements collected by...

Roads and bridges are vulnerable to a range of stressors, such as flooding, heat waves, and other extreme events. The probability of these stressors impacting roads and bridges cannot be exactly calculated due to various uncertainties related to the scientific understanding of future environmental conditions. Resilient design methods find ways to account for the uncertainty in various...

The diatom biochronology of ODP Holes 682A and 688E provides a nearly complete offshore reference section to correspond with onshore studies of the Miocene age materials of the East Pisco Basin of Southern Peru, which is known for its excellent preservation of fossil vertebrates. From these holes a nearly complete sequence of low latitude and northeastern Pacific diatoms has been...

This data release summarizes and documents the results of computations in support of the enhanced geothermal systems (EGS) fact sheet estimating electric-power resource potential for the Great Basin, USA (Burns and others, 2025b). All computations use the equations and best estimate values of parameters given in Burns and others (2025a). Temperature at each depth from Burns and others...

This data release includes digital geographic information system (GIS) data which was extracted from the U.S. Geological Survey Professional Paper 1300, volumes 1 and 2. Included are 14 shapefiles comprised of points, lines, and polygons representing the items shown in the page size figures from the reports, and one .lyrx symbology file for use in ArcGIS Pro. Also included are 364...

This dataset includes geochemical analytical results of rock samples sourced from drill core and hand specimens from the South Kawishiwi, Bald Eagle, Crocodile Lake, Cucumber Lake intrusions, and the Logan Sills, in the Duluth Complex, Minnesota. The dataset includes whole-rock and elemental geochemistry information with analysis methods used and qualifier (filtered) information where...

This dataset contains mineral chemistry data collected for bastnasite and other rare earth carbonate minerals from the Mountain Pass rare earth element deposit, California, USA. See related primary publication for a detailed description of this dataset.

This data release presents point data associated with studies to understand the crustal structure of the Blythe region, where strands of the pre-Quaternary Eastern California Shear zone project across this region in California and Arizona. Data include principal fact information for new gravity measurements collected by the U.S. Geological Survey from 2020 to 2025, previously unpublished...

International manganese samples in this collection were acquired from various countries, typically by geoscientists and university professors of the corresponding region. Manganese samples from the United States were collected in the field primarily by other USGS scientists noted in the dataset. The dataset corresponds to Hewett's physical collection of manganese-bearing samples re...
