A gravity survey being undertaken in eastern Western Australia will significantly enhance the quality of pre-competitive data available for mineral exploration companies, researchers and resource managers.

The survey is being carried out in the Eucla region by Geoscience Australia on behalf of the Geological Survey of Western Australia to collect data from a total of 14 700 new gravity stations.

The project is part of the Western Australian Exploration Incentive Scheme which is funded under the Western Australian Royalties for Regions program.

With the aid of a helicopter, the survey team will obtain measurements at 2.5 kilometre spacing on a north-south/east-west grid from 3800 stations in the Naretha, Culver and Balladonia area, 5700 stations in the Loongana and Madura area and 5200 in the Forrest and Eucla region.

The surveys will provide geoscientists with new gravity data for improved understanding of sub-surface geology and mineral potential of an area extending over 90 400 square kilometres in the Eucla Basin region of Western Australia.

The information will result in important context also for a range of land-use investigations, including soil mapping, groundwater and hydrogeology as well as for mineral resource exploration programs.

The survey data will be added to the Australian National Gravity Database which is maintained by Geoscience Australia and contains data from surveys conducted throughout Australia and on its Remote Offshore Territories.
