Airborne AFMAG EM and Ground MT Survey Comparisons Over the Pampa Lirima Geothermal Field in Northern Chile

The ZTEM results appear to correlate well with previous geophysics and the known geology, including known fault structures and contacts, as well as a prominent conductivity high over the Lirima hot spring field. 2D-3D inversions of the airborne ZTEM appear to agree quite well with 3D inversion of ground MT for shallower depths (<2km), in particular the conductive clay-cap attributed to the deep 3D MT conductive heat source and a resistive NE-SW lineament that extends between the Lirima and San Andres hot springs.
