GeoDAWN: Airborne magnetic and radiometric surveys of the northwestern Great Basin, Nevada and California

Description

This submission encompasses the airborne magnetic and radiometric survey data from the northwestern Great Basin in Nevada and California, collected under the GeoDAWN initiative: Geoscience Data Acquisition for Western Nevada. Included in the dataset are all flight details, geophysical data, and metadata gathered during the surveys. The U.S. Geological Survey (USGS) and the Department of Energy (DOE) have collaborated to acquire high-resolution airborne magnetic and radiometric data, over northern and western Nevada and eastern California, to support geologic and geophysical mapping and modeling that will assist geothermal and critical mineral studies. The surveys, referred to as GeoDAWN, span areas of major resource potential associated with the Walker Lane and western Great Basin. They were conducted under the USGS's Earth Mapping Resource Initiative (EarthMRI), with support from the DOE's Geothermal Technologies Office (GTO), and involved acquisition of aeroradiometric and aeromagnetic data that provide key information on surface geology and soil composition, and subsurface structure and geology, respectively.
