Program 3 - Geophysical and Geochemical Surveys
Airborne Magnetic and Radiometric Surveys
Prior to implementing the EIS, only 70 per cent of the State was covered by medium resolution airborne magnetic and radiometric surveys.
New airborne magnetic and radiometric surveys undertaken under the EIS will complete medium resolution airborne magnetics and radiometrics coverage of the State.
Deep Crustal Seismic Traverses
This activity, adding to a network of deep seismic traverses, will improve the understanding of the crustal structure of Western Australia.
Integrated geophysical and geological transects across the West Australian, North Australian and South Australian cratons and their margins in Western Australia, as well as the intervening Neoproterozoic and Phanerozoic Basins, will provide a key to the geological evolution of the Australian lithosphere over the Earth’s past 4 billion years. They will also provide an understanding of the crustal infrastructure hosting large mineral systems.
Regional Gravity and Geochemical Surveys
The objective of implementing regional gravity surveys is to provide 3D geological information to complement GSWA’s geological mapping programs in selected greenfield exploration areas.
Regional geochemical surveys will provide multi-element geochemical coverage of under-explored parts of the Yilgarn Craton to stimulate mineral exploration.
Data collected from the surveys will then be incorporated into GSWA’s web-based geochemical database. Regional ground gravity surveys and regional geochemical surveys will be completed simultaneously when they cover the same geographic area.
