Digital flight-line and gridded data for a high-resolution airborne magnetic and radiometric survey of this area. A total of 17,032 kilometers were flown along the lines, covering a 2,200 square-kilometer irregular area.

Data from 261 measurements of gravity measured in this area to compliment newly collected airborne magnetic data for surface and subsurface geologic mapping and to aid the subsurface interpretation of mapped and concealed Ediacaran-Ordovician alkaline intrusions related to rare earth element (REE) mineralization. Data are provided in CSV format.

Rock magnetic susceptibility measurements collected to understand the sources of airborne magnetic survey anomalies in this area. A total of 808 measurements were collected over 50 locations to identify concealed Ediacaran-Ordovician alkaline igneous features and potential rare earth element deposits. Data are provided in CSV format.
