Geophysical surveys
Airborne magnetic and radiometric surveys will be collected by Earth MRI over areas that have potential for critical mineral resources as a companion dataset to the geologic mapping and topographic (lidar) data. Such geophysical surveys help to identify buried rock types and geologic structures associated with mineral, energy, and groundwater resources and buried geohazards such as seismogenic faults. New Earth MRI-funded data are currently being collected. Please see available data through the geophysical data portal.
