PR – Datasets from five new airborne magnetic and radiometric surveys and three new ground gravity surveys have been released since November 2008. The data from these surveys can be interpreted to reveal the sub-surface geology of these areas and will be a valuable tool in assessing the mineral potential of the respective survey areas and will assist mineral exploration.
The South Kimberley airborne magnetic and radiometric survey covers the area in Western Australia where the Early Proterozoic Halls Creek Province meets the younger sediments of the Canning Basin. The Dumbleyung airborne magnetic and radiometric survey covers the soils and geology of the Waging, Dumbleyung, Kukerin, Kojonup and Katanning areas in southern Western Australia. This survey was funded by the South West Catchments Council (SWCC) in partnership with the Western Australian Department of Mines and Petroleum.
The Cooper Basin East & West airborne magnetic and radiometric surveys cover the Early Permian to Early Triassic Cooper Basin that underlies the Mesozoic Eromanga Basin in southern Queensland. The Normanton airborne magnetic and radiometric survey covers the Karumba Basin in northern Queensland.
The Westmoreland – Normanton gravity survey covers the Carpentaria and Karumba Basins, the Windimurra gravity survey covers the northern Yilgarn Province in Western Australia and the Central Arunta gravity survey covers the area where the Arunta Block meets the Amadeus and Georgina Basins in the Northern Territory.
All of these surveys were managed by Geoscience Australia on behalf of the relevant state geological survey. The data have been incorporated into the national geophysical databases. The point-located and gridded data for the surveys can be obtained free online using the Australian governments’ Geophysical Archive Data Delivery System (GADDS).
