Magnetotelluric investigation complement multi-disciplinary geophysical data

Abstract

As part of the Australian Government?s Onshore Energy Security Program, Geoscience Australia has acquired magnetotelluric data along 12 deep crustal seismic reflection transects in Australia. The magnetotelluric projects, which total more than 640 stations over 3700 km in distance, have been undertaken by Geoscience Australia in collaboration with state and territory geoscience agencies. Broadband and long period MT data have been acquired for investigating geological structures from the shallow surface to upper mantle. These data, along with the deep seismic reflection, magnetic, gravity and geological data form the basis for multi-disciplinary investigations of crustal architecture, and energy and mineral potential, providing precompetitive information to industry and researchers.
