Airborne electromagnetic and magnetic survey data, Silverton, Colorado, 2019

Airborne electromagnetic (AEM) and magnetic survey data were collected during April and May 2019 along 1,467 line-kilometers in the San Juan-Silverton Caldera complex, Colorado, in the Southern Rocky Mountain Volcanic Field. Data were acquired by Geotech, Ltd. with the versatile time-domain electromagnetic (VTEM-ET) system together with a Geometrics optically pumped cesium vapor magnetometer. The

GIS Data for Geologic Map of Precambrian Metasedimentary Rocks of The Medicine Bow Mountains, Albany and Carbon Counties, Wyoming

This U.S. Geological Survey (USGS) data release provides a digital geospatial database for the geologic map of Precambrian metasedimentary rocks of the Medicine Bow Mountains, Albany and Carbon Counties, Wyoming (Houston and Karlstrom, 1992). Attribute tables and geospatial features (points, lines and polygons) conform to the Geologic Map Schema (GeMS, 2020) and represent the geologic map plates a

Gravity data in the Wet Mountains area, southcentral Colorado, 2021 to 2022

The U.S. Geological Survey (USGS) collected gravity data in the Wet Mountains, CO from September 2021 to July 2022 to compliment newly collected airborne magnetic data for surface and subsurface geologic mapping. A total of 261 measurements were collected across two Ediacaran-Ordovician alkaline complexes (Gem Park and McClure Mountain) and gabbroic outcrops suspected Ediacaran-Ordovician in age.

Magnetic susceptibility measurements in the Wet Mountains, Colorado, 2021 to 2022

The U.S. Geological Survey (USGS) collected rock magnetic susceptibility measurements to understand the causative sources of airborne magnetic survey anomalies in the Wet Mountains, Colorado. A total of 808 measurements were collected over 50 locations from August 2021 to June 2022 on rocks ranging from Paleoproterozoic to Oligocene age. These measurements aid the interpretation of newly collected

Geochemical data for carbonatite samples from the Mountain Pass rare earth element deposit, southeast California

This data release contains whole-rock major, minor, and trace element geochemical data for carbonatite samples from the Mountain Pass rare earth element (REE) deposit located in southeastern California. The Mountain Pass deposit is the largest REE deposit in the United States and in 2021, produced 43,000 metric tons (expressed as rare-earth-oxide equivalent; U.S. Geological Survey, 2022). Samples

Airborne magnetic and radiometric survey, Virginia and North Carolina Fall Zone, 2021

This data release provides digital flight line data for a high-resolution airborne magnetic and radiometric survey over Virginia and North Carolina along and near the eastern U.S. 'Fall Zone', which represents the transitional area between Atlantic Coastal Plain sediments and Piedmont metamorphic and igneous rocks. The airborne data collection was funded by the U.S. Geological Survey (USGS) Earth

U-Pb and Ar-Ar age data and whole rock geochemistry data of igneous and metasedimentary rocks of northeast Afghanistan

This dataset accompanies the proposed publication, 'Geochronology and geochemistry of igneous and metasedimentary rocks of northeast Afghanistan: A refinement of the timing and origin of crustal terranes', which focuses on refining the geochronology and geochemistry of these rocks during multiple time periods of accretion, regional metamorphism, and magmatic activity. The analyses were performed f

HySpex by NEO VNIR-1800 and SWIR-384 imaging spectrometer radiance and reflectance data, with associated ASD FieldSpec® NG calibration data, collected at Cripple Creek Victor mine, Cripple Creek, Colorado, 2017

HySpex by NEO (HySpex) VNIR-1800 and SWIR-384 imaging spectrometer radiance data were acquired on September 14, 2017 at the Cresson Pit of the Cripple Creek & Victor mine in Cripple Creek, Colorado. ASD FieldSpec® NG data were collected on September 13 and 14, 2017 at two calibration sites within the Cresson Pit imaged with the HySpex imaging spectrometers. The HySpex VNIR-1800 imaging spectromete

U-Pb zircon geochronology data from Eocene igneous rocks in the Stibnite-Yellow Pine mining district and vicinity, Idaho

This data release includes laser ablation inductively coupled plasma mass spectrometry (LA-ICPMS) U-Pb zircon geochronology data to determine the ages of Challis igneous rocks in the Thunder Mountain volcanic field and dikes west of the volcanic field, especially in and near the Stibnite-Yellow Pine mining district, ID. These efforts were made to help understand the stratigraphy and lithologic cha

Alaska permafrost characterization: Geophysical and related field data collected in 2021

Geophysical measurements were collected by the U.S. Geological Survey (USGS) at five sites in Interior Alaska in September 2021 for the purposes of imaging permafrost structure and quantifying variations in subsurface moisture content in relation to thaw features. Electrical resistivity tomography (ERT) measurements were made along transects 110-222 meters (m) in length to quantify subsurface perm

Surface electrical resistivity tomography, magnetic, and gravity surveys in Redwell Basin and the greater East River watershed near Crested Butte, Colorado, 2017

Surface electrical resistivity tomography (ERT), time-domain electromagnetics (TEM), nuclear magnetic resonance (NMR), magnetics, and gravity data were acquired in 2016, 2017 and 2018 in the greater East River Watershed near Crested Butte Colorado with a focused effort in Redwell Basin. Five ERT profiles were acquired within Redwell Basin and Brush Creek to map geologic structure at depths up to 4
