Geoscience Australia has actively applied the method to provide multiscale world-leading datasets to improve the understanding of geology and resource potential. We demonstrate the value of scaled MT data acquisition starting from mapping large-scale conductivity structures in the lithosphere utilising long-period MT datasets through to the resolution of finer scale structures in the crust suitable for camp scale targeting. Integration of data from multiscale surveys provides an effective way to narrow the search space and to identify ‘targets’ of mineral potential in covered terranes. Our work has helped to increase explorers’ investment confidence for new mineral discoveries in greenfield regions. {"type": "Polygon", "coordinates": [[[112.0, -44.0], [154.0, -44.0], [154.0, -9.0], [112.0, -9.0], [112.0, -44.0]]]} 112.0 154.0 -44.0 -9.0 EARTH SCIENCES Published_External Wednesday Seminar magnetotelluric methods Link to YouTube video documentDigital Link to YouTube video HTML
