Data

A mineral resource assessment for lithium was carried out by the U.S. Geological Survey (USGS) for the southern Appalachian region, between latitudes 31N and 40N and longitudes 75W and 89W, in the following states: Maryland, Virginia, North Carolina, South Carolina, Tennessee, Georgia, Alabama. This study (Rosera and others, in press) integrates data from several sources, including...

This data release includes control point locations, depths, stratigraphic context, and reference information used to constrain the sedimentary and tectonic history of Chehalis Basin

This digital database is an inventory of microfossil samples in units or formations containing mottled mudstones and units or formations stratigraphically above and below units containing mottled mudstones. This database contains detailed information about each sample (e.g., USGS laboratory number, field number, collector and date collected, location quadrangle etc.) and database entries...

Rock physical property measurements were collected on outcrops to help understand the causative sources of gravity and magnetic survey anomalies in the southern Medicine Bow Mountains of Wyoming. A total of 539 magnetic susceptibility measurements and 318 density measurements have been conducted. The resulting data aid in interpretation of gravity and airborne magnetic data that are...

This data release provides digital geospatial data related to the three-dimensional geologic model (Hosford Scheirer, 2013) that was used as a framework for conducting the 2003 oil and gas assessment of the San Joaquin Basin province, California (Gautier and others, 2004; Hosford Scheirer, ed., 2007). The data release includes raster GeoTIFF files of the tops of the 15 composite geologic...

This data release provides vector flight-line (point) and raster data for a high-resolution airborne magnetic and radiometric survey over a part of the eastern Great Basin, Nevada. 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...

This release of whole-rock geochemical data for northwestern Utah and adjacent states is for volcanic rocks sampled and analyzed from 1977 to present. The rocks range from Eocene to Quaternary in age and represent lava flows, tuffs, and subvolcanic intrusions. The data release includes new, previously unpublished data as well as results for USGS-processed samples that are publicly...

Presence/absence data for Erodium pollen in a sediment core taken from the Morro Bay Salt Marsh.

This release of whole-rock geochemical data for northwestern Utah and adjacent Idaho and Nevada is for unaltered intrusive rocks sampled and analyzed from 1980 to 2023. The rocks range in age from Archean to Cenozoic. Most samples represent plutons, stocks, and dikes of Mesozoic and Cenozoic age. A few older igneous and metamorphic rocks are included. The data support several map...

Microplastics (MPs) are an environmental concern. They can interact with other contaminants and pose new threats to organisms. We assessed the effect MPs on silver (Ag) bioaccumulation in the filter-feeding zooplankton Daphnia magna exposed to Ag nanoparticles at environmentally relevant concentrations.

This data release provides annual values for the 19 standard bioclimatic variables (BIO1–BIO19) for the Contiguous United States, computed from the downscaled CMIP6-LOCA2 temperature and precipitation dataset for 1950–2100. Daily maximum temperature, minimum temperature, and precipitation from 27 CMIP6-LOCA2 GCMs were processed using the Python xclim library to generate bioclimatic...

Geochemical data include major, minor and trace element results for alkaline silicate igneous rock samples from the Bear Lodge alkaline complex. Samples were collected during field work from natural exposures/outcrops and drill core. Samples were analyzed by the GeoAnalytical Lab at Washington State University and U.S. Geological Survey contract laboratories, AGAT Labs and SGS Labs...
