Releases airborne survey data, resistivity cross-sections and depth slices derived from data inversion. Resulting resistivity models confirm geologic framework, constrain hydrostratigraphy and depth to basement, and reveal fault and fold distribution.

Geological, geophysical, geochemical, or lidar data acquisition projects funded by the Earth Mapping Resource Initiative (Earth MRI) pertaining to the study of critical mineral resources in the US.

Geologic map units, faults, structural lines meaning axial traces, structural points like bedding strike and dip locations, cross section lines, drill core sample locations, open pit polygons or outlines, and general mining features such as the location of an adit. Data are provided in shapefile format.

A planned partnership between the USGS, the Association of American State Geologists, and other Federal, State, and private organizations to collect scientific information useful for finding and exploiting critical mineral resources in the US.
