Geophysical exploration holds paramount importance in the discovery of new mineral deposits at progressively greater depths. Rapid reconnaissance is most effectively achieved through airborne geophysical methods, whereas ground-based methods excel in delineating intricate targets.
Electromagnetic (EM) techniques, both airborne and ground-based, are particularly well-suited due to the pronounced conductivity contrast between host rocks and certain ore deposits or associated secondary alteration.
We compare the geophysical signatures of two theoretical airborne natural-source EM systems with those derived from ground-based magnetotellurics for a realistic resistivity model of an ore deposit. This comparative analysis underscores the advantages of integrating airborne and ground measurements.
