Data

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...

This data release documents sixteen 5-year simulations using the USGS SUTRA groundwater flow modeling software and includes the full output from one 5-year simulation for verification that the model code runs properly. The most recent version of SUTRA (version 4.0) was used to evaluate aquifer (ATES) and reservoir (RTES) thermal energy storage performance to support economic analyses by...

This dataset consists of zircon uranium-lead (U-Pb) isotopic compositions, ages, and trace-element compositions in addition to whole-rock chemical compositions from plutons within the Sierra Nevada, California. These samples primarily collected from 2015 to 2023, although some legacy data are included. Zircon crystals were analyzed using the Sensitive High-Resolution Ion Micro-Probe...

A rockfall occurred between the night of January 5 and the morning of January 6, 2025 on the Point Bonita Trail in the National Park Service Golden Gate National Recreation Area, California. The rockfall originated from a granodiorite rock face in the Franciscan Formation and deposited approximately 25 cubic meters of rock on the pedestrian trail below. The U.S. Geological Survey...

This data release contains P- and S-wave velocity data from logs of nine wells in three large sedimentary basins in the San Francisco Bay region. The logs were collected between 2000 and 2006 for the U.S. Geological Survey under contract by R.A. Steller of GeoVision using an Oyo suspension logging system. Well depths range from 215 to 407 meters and sample spacing in the wells ranges...

This dataset contains geochemical data collected for melt inclusions and rocks of the McDermitt caldera, Oregon, USA. See related primary publication for a detailed description of this dataset. https://doi.org/10.1130/G53140.1

This dataset consists of 529 areas of identified nickel laterite in southern Oregon and northern California, compiled in vector shapefile format from six historical publications from 1956 to 1983. Sources include state and federal projects for geologic mapping and critical mineral exploration purposes and are attributed to each polygon. Five original, georeferenced maps are included in...

This data release is companion to a manuscript entitled: "Carving North America’s Deepest Gorge: Constraints on the Timing and Mechanism of forming Hells Canyon". Here, we report cosmogenic age data analyzed from sediments deposited within caves within the Hells Canyon region, as well as the knick point locations mapped out from topographic analysis and detrital zircon U-Pb ages derived...

The dataset includes .csv spreadsheets which provide whole rock geochemical data for the alkaline silicate rock and carbonatite rock samples for the Mountain Pass Intrusive Suite that were analyzed as part of this study, as well as whole rock Rb-Sr and Sm-Nd isotopic data for whole rock alkaline silicate samples. The .csv files containing this data are associated with individual data...

We measured the magnetic fabric of 205 oriented paleomagnetic specimens, subsampled from 97 samples collected from 15 dikes of the Monument dike swarm. Anisotropy of magnetic susceptibility is the directionally dependent response of a specimen to an induced magnetization and is a function of the magnetic mineral properties (e.g., size, shape, mineralogy, domain state, orientation). We...

These datasets include photographic images of thin sections created from hand samples and drill core collected from mafic to ultramafic rocks from different locations across the U.S., shapefiles representing the locations of the hand samples and/or drill core collars, and images showing examples of the approximate scale on the images. The samples were collected in order to help define...

Three different CMIP6-LOCA2 based climate projection data sets are spatially averaged for the contiguous United States using National Park Service administrative units to provide time series for analysis. The primary data set is the statistically downscaled CMIP6-LOCA2 (Localized Constructed Analogs, v20220519 version, Pierce et al. 2023), which includes temperature and precipitation...
