Data

Airborne electromagnetic (AEM) and magnetic survey data were collected during November 2022 over a total distance of 2,372 line kilometers over two study areas in the Pleasant Valley near the city of Coalinga, California and the region surrounding the Pyramid Hills. These data were collected adjacent to areas of oil and gas production in support of groundwater salinity mapping and...

This U.S. Geological Survey (USGS) data release contains analytical data from a suite of mineral samples collected from the Mount Weld carbonatite complex, western Australia. This complex hosts the largest producing rare earth element (REE) mine outside of China. The REEs are mined from the weathered material, a laterite, derived from an underlying carbonatite. Samples were collected...

This dataset consists of eight sandstone samples and four ash samples collected from the Bidahochi basin that were analyzed for U-Pb zircon ages. The dataset accompanies the publication "Late Miocene Colorado River arrival in Bidahochi basin permits spillover origin of Grand Canyon". Samples were collected from the field by Ryan Crow (USGS) and John Douglass (Paradise Valley Community...

This data release provides digital flight line data for a high-resolution airborne magnetic and radiometric survey over the Hartville Uplift and Shirley Mountains regions of Wyoming. The survey is split into two blocks, one covering the Hartville Uplift region (Block A), and the other covering the Shirley Mountains region (Block B). The airborne survey was mainly funded by the State of...

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 encompasses whole rock geochemical data determined on iron ore and host rock samples collected in California, Nevada, and Utah from March 2023 through June 2024. Whole rock geochemistry was conducted on 269 samples. Major element oxides were determined by borate fusion and wavelength dispersion X-ray fluorescence; 61 elements were determined by sodium peroxide fusion...

These data are for a geochronologic study of Cretaceous Elkhorn Mountains Volcanics and several discrete satellite plutons adjacent to the Cretaceous Boulder batholith of western Montana. Zircon from the two volcanic units of the Elkhorn Mountains Volcanics and four samples of satellite plutons of the Boulder batholith were dated by sensitive high resolution ion microprobe (SHRIMP). When...

This dataset presents a recalculated compilation of geochronology ages of Cretaceous-Miocene intrusive rocks and volcanic plugs in the northern Rocky Mountains USA, with a focus on Montana and Idaho. Mineral assessments and prospectivity mapping requires detailed spatiotemporal understanding of magma systems in the upper crust to predict when and where ore deposits may have formed...

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...

The data set contains geochemical data for 1,524,014 rock, sediment, soil, and mineral samples collected by the U.S. Geological Survey within US state, territory or Economic Exclusive Zone (EEZ) boundaries, and analyzed from 1962 through 2023 either in the analytical laboratories of the Geologic Discipline of the USGS or by contract with commercial analytical laboratories. These data...

This U.S. Geological Survey (USGS) data release is a collaborative geospatial database compiled by the USGS and participating State geological surveys, with support from the Earth Mapping Resources Initiative (Earth MRI) program. The database represents the first phase of cataloging above-ground mine waste features —such as tailings and waste rock piles— that are remnants of historical...

We present isotopic and geochemical data for several Archean and Paleoproterozoic metamorphic rocks in the Penokean orogen, USA. These data include new U-Pb and trace element analyses of apatite, titanite, and monazite; bulk rock major and trace element compositions; and whole rock and garnet Lu-Hf and Sm-Nd isotope compositions.
