Assess whether integrated multiscale electromagnetic surveys can reliably resolve structural and stratigraphic information at depth for geological mapping and mineral exploration in sedimentary basins.
Applied 1D inversion modeling to regional TEMPEST airborne electromagnetic survey data.
Applied 3D inversion modeling to coinciding magnetotelluric survey data integrated with downhole electrical property measurements.
Demonstrated that the Johnson Cairn Formation is anomalously conductive, enabling identification of faults, folds, and stratigraphic thickness variations to depths of several kilometers.
Identified that the resistive Juderina Formation produces distinct electromagnetic responses, indicating the need for substantial revisions to regional published geological maps.
