Abstract
As part of the Australian Government's Energy Security Program (2006-2011), Geoscience Australia (GA) has acquired magnetotelluric (MT) data (more than 3000 km in distance) in conjunction with deep crustal seismic reflection along 12 transects in Queensland, South Australia, Northern Territory and Western Australia. These data, along with total magnetic intensity, gravity and geological data form the basis for multi-disciplinary investigations of energy and mineral potential and crustal architecture, providing pre-competitive information to industry and researchers. These MT projects have been undertaken by GA in collaboration with relevant state and territory geological surveys and The University of Adelaide. MT data were collected using AusScope MT instrumentation through ANSIR (National Research Facility for Earth Sounding) agreement and by a contractor with different equipment. Different survey design and acquisition parameters were used for different projects. While processing, analysis and modelling of data are ongoing, preliminary results of two dimensional models confirm the complementary value of MT to seismic interpretations. However, electrical resistivity of Earth materials is a complex property and MT responses represent a more complex Earth than one or two dimensions.
