GIS Data for Geologic Map of Precambrian Rocks of the Sierra Madre, Carbon County, Wyoming and Jackson and Routt Counties, Colorado

This U.S. Geological Survey (USGS) data release provides a digital geospatial database for the Geologic map of Precambrian rocks of the Sierra Madre, Carbon County, Wyoming, and Jackson and Routt Counties, Colorado (Houston and Graff, 1994). Attribute tables and geospatial features (points, lines and polygons) conform to the Geologic Map Schema (USGS NCGMP, 2020) and represent the...

Laser-ablation inductively-coupled-plasma mass spectrometry and electron probe microanalyses of pyrite and pyrrhotite in tailings and ores from volcanogenic massive sulfide and sedimentary-exhalative deposits

Mine waste, including mill tailings, could host substantial critical mineral resources. Developing an understanding of the mineral hosts and occurrence of critical minerals in mine waste is essential to evaluating their resource potential. Volcanogenic massive sulfide (VMS) and sedimentary-exhalative (SEDEX) deposits are important global sources of copper, zinc, lead, gold, and silver...

Visible and Near Infrared (VNIR) and Short Wavelength Infrared (SWIR) Spectra of Select Altered Mafic and Ultramafic Rock Samples from the Josephine Peridotite in CA and OR, the Yukon-Tanana region in Alaska, and from the Southern Appalachians in VA, NC,

These data are laboratory reflectance measurements conducted on a suite of altered mafic and ultramafic rocks. Visible-Near InfraRed (VNIR) and Short-Wave InfraRed (SWIR) reflectance measurements were made (~0.4 – 2.5 microns) using an artificial light source connected to an Analytical Spectral Devices (ASD) spectrometer. Spectra from a total of 91 samples were measured and analyzed...

Geochemical and Mineralogical Data from Legacy Mine Land Sites in Central Colorado, 2019 - 2020

This U.S. Geological Survey (USGS) data release contains data from stream water, groundwater/springs, and sediment samples collected from legacy mine land (LML) sites in central Colorado. The sites were selected using a GIS-based approach that integrated regional geological and geochemical datasets with known mine features and satellite data identifying hydrothermal alteration (ASTER) to...

Principal facts of regional gravity data in the Medicine Bow Mountains, Wyoming, 2022-2024

Gravity data were collected in 2022-2024 to assist in mapping surface and subsurface geology in the Medicine Bow Mountains of southern Wyoming. This data release provides principal facts for 738 new gravity stations that were acquired to supplement existing public gravity data coverage.

U-Pb zircon geochronology data for Spinney Mountain and Guffey NW Geologic Maps, Park County, CO

This data release includes laser ablation inductively coupled plasma mass spectrometry (LA-ICPMS) U-Pb zircon geochronology data from four samples collected from rock units located in the Spinney Mountain Quadrangle and the Guffey NW Quadrangle in Park County, Colorado. Samples were collected from gniess and granite rocks, and age data was used to support publication of updated maps by...

GIS Data for Geologic Map of the Eastern Part of the Challis National Forest and Vicinity, Idaho

This U.S. Geological Survey (USGS) data release provides a digital geospatial database for the geologic map of the eastern part of the Challis National Forest and vicinity, Idaho (Wilson and Skipp, 1994). Attribute tables and geospatial features (lines and polygons) conform to the Geologic Map Schema (USGS NCGMP, 2020) and represent the geologic map as published in U.S. Geological Survey...

GIS Data for Selected Data from the Geologic Map of the Western Part of the Cut Bank 1 Degree x 2 Degrees Quadrangle, Northwestern Montana

This U.S. Geological Survey (USGS) data release updates the digital geospatial database for the southern portion of the geologic map of the western part of the Cut Bank 1 degree x 2 degrees quadrangle, northwestern Montana (Harrison and others, 1998). Attribute tables and geospatial features (points, lines, and polygons) conform to the Geologic Map Schema (USGS NCGMP, 2020). The 899,246...

LA-MC-ICP-MS Hf isotopes in zircons from the Mountain Pass Intrusive Suite, California

This U.S. Geological Survey (USGS) data release accompanies planned publication ‘Geochemistry and radiogenic isotopes constrain the mantle source region of the Mountain Pass Intrusive Suite, California' and planned data release 'Whole-rock geochemical and isotopic data for the Mountain Pass Intrusive Suite, California'. The data release includes laser ablation multi-collector inductively...

LA-ICP-MS U-Pb Geochronology Data for Igneous Rocks Constraining the Timing of the Great Lakes tectonic zone, central Upper Peninsula, Michigan, USA

This U.S. Geological Survey (USGS) data release accompanies planned publication ‘New constraints on location and timing of the Great Lakes tectonic zone, central Upper Peninsula, Michigan, USA. The data release includes laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) U-Pb zircon data and/or U-Pb apatite data for two samples from the Upper Peninsula, Michigan, USA...

Argon data for samples from Kenya and Ethiopia

Ar/Ar data are for 12 samples that record the eruption age of tephra. The geochronology provides time constraints for the ages of tephra and interbedded sediments and fossils from Kenya and Ethiopia. Samples were collected by Erin Dimaggio (Pennsylvania State University), who brought them to the USGS Denver Argon Geochronology Laboratory for Ar/Ar analysis. Samples were analyzed in...

Gravity data in the Upper Peninsula, Michigan for geophysical profile modeling of the Midcontinent Rift System and associated structures

Gravity data were collected from 2022 through 2024 to provide more detailed data for geophysical profile modeling of the Midcontinent Rift System and associated structures. This data release provides the complete Bouguer anomaly gravity data for 256 new gravity stations to supplement existing data and replace erroneous existing data.
