Abstract
The Australian earth sciences have been recognized as part of Australia's key scientific capability to understand the structure and evolution of the Australian continent. Over the last five years, Geoscience Australia, through its Onshore Energy Security Program (OESP), in conjunction with the State and Territory Geological Surveys, the Predictive Mineral Discovery Cooperative Research Centre (pmd*CRC), the AuScope Earth Imaging (under Australian Government's National Collaborative Research Infrastructure Strategy) and the Australian National Seismic Imaging Resource has acquired over 6,500 line kilometres of new world-class seismic reflection data and over 3,700 kilometres of magnetotelluric (MT) data from more than 640 stations. Geoscience Australia acquires high quality deep seismic reflection data in most of Australia's economically significant geological regions, by collecting at least one deep seismic reflection traverse across the key structures. The acquisition parameters for regional vibroseis surveys have been selected from broad experience in hard rock environments and experimental programs prior to seismic acquisition. Three IVI HEMI-50 or 60 peak force vibrators are used with three 12 s varisweeps with 80 m between vibration points, 40 m group interval, and 20 s listening time to image down to approximately 60 km in depth. Geoscience Australia continues to provide expertise in deep crustal seismic reflection processing and mineral province interpretation to collaborative research programmes which focus on understanding the 3D crustal architecture and mineral systems within `hard-rock' mineral provinces. As part of this program , broadband and long period MT data have been acquired along 12 deep seismic reflection transects across potential mineral provinces and frontier sedimentary basins.
