Surfaces representing the basal mineralized zone in the South Kawishiwi, Bathtub, and Partridge River Intrusions, Duluth Complex, Minnesota

This dataset includes five Esri grids representing the copper-nickel-platinum group element (Cu-Ni-PGE) mineralized zone found in the South Kawishiwi, Bathtub, and Partridge River intrusions, Duluth Complex, Minnesota. The data are also presented in .csv format to provide an open-source file type. We are using the term "basal mineralized zone" (bmz) as an informal term representing the mineralized

Gravity data and geophysical gradient data of the Stockton 30 x 60 minute quadrangle, California

This data release presents point data associated with the geologic and geophysical maps of the Stockton 30 x 60 minute quadrangle, California. Data include principal fact information for new gravity measurements collected by the U.S. Geological Survey from 2015 to 2018 and for existing gravity data. Gravity and magnetic gradients were also calculated in the Stockton 30 x 60 minute quadrangle, Cali

Aeromagnetic Data and horizontal gradient maxima of Garlock, California, and Surrounding Areas in California

This data release provides access to an aeromagnetic survey and magnetization boundaries over Garlock, California and surrounding areas in southern California. The survey extends from the city of Bakersfield across the southern Sierra Nevada and Tehachapi Mountains and west over Indian Wells Valley and the towns of Mojave and Rosamond to just northwest of the town of Barstow. These data were acqui

Magnetotelluric data across the Southern San Andreas Fault Zone, California

The Southern San Andreas fault (SSAF) poses one of the largest seismic risks in California. However, structural properties around Coachella Valley remain enigmatic. In 2019, we collected magnetotelluric soundings (MT) to help inform depth-dependent fault zone geometry, fluid content and porosity. This project was led by the Institute of Geophysics and Planetary Physics at the University of Califor

Digital photographs using a remotely piloted unoccupied aerial system and derived point clouds for bluffs in Ludington, MI, July 11, 2019, and July 14, 2021

Images were collected using a remotely piloted unoccupied aerial system (UAS) over the bluffs of the eastern shore of Lake Michigan in Ludington rural area, Mason County, MI. Images were collected in two separate surveys conducted on July 11, 2019, and July 14, 2021, using a DJI Phantom 3 and 4 PRO commercial UAS respectively operated by the University of Toledo. The images cover an extent between

Short vs intermediate-term fate of glucose and oxalic acid in surface and subsurface soils of a coastal grassland near Santa Cruz California

Though the primary sources of organic matter to soil are plant inputs, the role of microorganisms as mediators of soil organic carbon preservation is increasingly recognized in the context of biological contributions to long-lived soil organic matter. However, current knowledge of sub-soil processes is insufficient to model microbial-derived carbon flow particularly at depth. Using a previously st

Digital database of geologic units, contacts, and faults for Mineral Resource Potential Map of the Turtle Mountains Wilderness Study Area, San Bernardino County, California (U.S. Geological Survey Bulletin 1713-B, 1988, Plate 1)

This map geodatabase digitally represents the general distribution of bedrock geologic map units in the Turtle Mountains area, California, as portrayed in Plate 1 of USGS Bulletin 1713-B, Mineral resources of the Turtle Mountains Wilderness Study Area, San Bernardino County, California (1988), https://doi.org/10.3133/b1713B. The map covers parts of the Rice, Turtle Mountains, and Savahia Peak 15’

Stillwater Complex, Montana: Logs of core drilled by Chrome Corporation of America in the Mountain View area, 1988 to 1990

This dataset includes TIFF (Tagged Image File Format) images of graphic drill core logs showing associated drill core information, a TIFF image of the explanation for the lithology and structure sections of the logs, an Esri shapefile of the locations of the drill holes, and 17 individual .csv files of tabular data that were compiled from handwritten drill core logs. The drill core is from the Mou

Structural measurements and their calculated surface traces, South Kawishiwi area, Duluth Complex, Minnesota

This dataset includes a point shapefile representing structural measurements taken from a study area near the South Kawishiwi Intrusion in the Duluth Complex, Minnesota and a line shapefile representing the surface traces of the structural measurements. The structural measurements point file consists of a compilation of data from multiple published and unpublished sources. The surface trace file w

Deep (15-second) seismic reflection profiles CC-1 and CC-2 extending from the eastern California Coast Ranges across the Great Valley into the Sierran foothills at about latitude 37.25 Degrees N

This data release contains deep seismic reflection profiles CC-1 and CC-2, which extend eastward from within the California Coast Ranges across the Great Valley and into the Sierran foothills, with a combined east-west length of about 140 km at about the latitude of the town of Merced (37.25° north latitude). The records are processed to 15 seconds two-way time and thus extend deep into the lithos

Electrical Conductance Maps of the Great Basin, USA

Images of subsurface electrical conductivity are useful for locating fluids and other electrically conductive phases at depth in the Earth. This data release presents electrical conductance maps estimated from a 3D model of the Great Basin, USA, at five different depth ranges, spanning 2 to 200 km depth. Electrical conductance is the integration of electrical conductivity in a depth range. Great B

X-ray Fluorescence Geochemistry of Columbia River Basalt Group Rocks in the Western Columbia River Gorge

This table contains geochemical data collected for whole-rock samples from the Columbia River Basalt Group in the western Columbia River Gorge in Oregon and Washington. Most samples were collected by Russell C. Evarts and Richard M. Conrey from 2002 to 2014. Samples were collected during traverses along roads, streams, ridgecrests, and other areas as part of ongoing geologic mapping. Additional sa
