Data

Gravity data were collected in 2022 and 2023 to assist in mapping surface and subsurface geology in the central Upper Peninsula of Michigan. This data release provides principal facts for 666 new gravity stations that were acquired to supplement existing public gravity data coverage.

The U.S. Geological Survey (USGS) collected rock physical property measurements to help understand causative sources of gravity and magnetic survey anomalies in the central Upper Peninsula of Michigan. A total of 1,460 measurements of magnetic susceptibility and density from 61 outcrops and 37 boreholes have been conducted on Precambrian rocks. The measurements aid in interpretation of...

This dataset consists of seven lava samples that were analyzed for Pb, Sr, and Nd isotopes. The dataset accompanies the planned publication, ‘The geochemical and petrogenetic evolution of Þingmúli central volcano: Insights to magma processes in Iceland’, as well as planned future publications on this volcanic complex. Pb, Sr, and Nd isotope data were used for this study to determine...

This dataset accompanies proposed publication, "Tectonic disruption of the Proterozoic Yavapai-Matzatzal Province boundary near Sierra Hornaday, northwest Sonora", to be published in a Geological Society of America publication, which will report zircon SHRIMP-RG U-Pb ages and Sm-Nd whole rock isotope analyses to map the path of the Yavapai-Matzatzal province boundary across southwest...

These U-Pb zircon geochronology and whole rock geochemistry data were collected as part of a bilateral campaign of the U.S. Geological Survey (USGS) with the Uzbekistan Ministry of Mining, Industry, and Geology (MinGeology; formerly GOSCOMGeology) to support a new quantitative/qualitative mineral resource assessment for tungsten, gold, rare-earth elements, graphite, and uranium in the...

This U.S. Geological Survey (USGS) data release provides a digital geospatial database for the geologic map of the White Rock Canyon quadrangle, Carbon County, Wyoming (Hyden and others, 1968). Attribute tables and geospatial features (points, lines and polygons) conform to the Geologic Map Schema (GeMS, 2020) and represent the geologic map as published in USGS Geologic Quadrangle Map GQ...

The data release for geologic maps of Ravalli Group and other Mesoproterozoic Belt Supergroup strata in northern Idaho and northwestern Montana is a digital, Geologic Map Schema (GeMS)-compliant version of maps published in U.S. Geological Survey (USGS) Open-File Report 2001-438 (Boleneus and others, 2001). The new digital data present attribute tables and geospatial features (points...

The Yukon-Tanana Upland airborne magnetic geophysical data merge provides a merged raster grid of magnetic data for the Yukon-Tanana Upland (YTU), Alaska. This dataset provides a regionally consistent magnetic grid while retaining as much detail as possible of the originating data by leveling all the region's magnetic grids to one another. This 100-m cell-size magnetic grid of the YTU...

This data release provides digital flight line data for a high-resolution airborne magnetic and radiometric survey over the Medicine Bow Mountains in southern Wyoming. The airborne survey was jointly funded by the Earth Mapping Resources Initiative and the Wyoming State Geological Survey (WSGS). The survey was designed to meet complementary needs related to geologic mapping and...

This U.S. Geological Survey (USGS) data release provides a digital geospatial database for the geologic map of the Bayhorse area, central Custer County, Idaho (Hobbs and others, 1991). Attribute tables and geospatial features (points, lines, polygons) conform to the Geologic Map Schema (GeMS, 2020) and represent the geologic map as published in the USGS Miscellaneous Investigations...

This dataset includes thin section images, automated mineralogy mineral maps, whole-rock geochemical data, and whole-rock Nd-Sr-Pb isotopic analysis of samples collected from nine mafic-ultramafic outcrops in the Wet Mountains, southern Colorado, during the summer of 2022. These data will accompany an upcoming journal publication and are intended to supplement recently collected airborne...

This data release provides digital flight-line and gridded data for a high-resolution airborne magnetic and radiometric survey over the southwestern portion of the Colorado Mineral Belt, southwestern Colorado. The Colorado Mineral Belt is a broad, northeast-southwest trending alignment of historic mining districts that have produced multiple types of commodities, including critical...
