Geoscience Australia and the Office of Minerals and Energy Resources SA announce the release of digital point located and gridded gravity data from recent gravity surveys over the South Olympic, Lake Harris and Mulgathing regions of the Gawler Craton in South Australia. The data were acquired by Primary Industries and Resources South Australia (PIRSA) as part of its Targeted Exploration initiative South Australia (TEiSA) in collaboration with Geoscience Australia's Gawler Craton Mineral Promotion Project. Data collected during the survey provide the framework necessary for government and industry to assess resource potential, determine land use and environmental management policies, and aid in the planning of more detailed exploration activities. The survey comprises 3533 new gravity stations acquired over various station spacings. For the South Olympic region, stations were acquired on irregular 4 x 4 and 2 x 2 km grids. A regular 4 x 2 km grid was used in the Mulgathing region. In the Lake Harris region, data were acquired on a 4 x 1 km grid with a portion being infilled at 2 x 1 km, over the outcropping Lake Harris greenstone belt. Data were acquired over the period April to May 2001. The digital data are available from Geoscience Australia on CD-ROM. Contact the Sales Centre.

Full-colour map summarises the major Proterozoic mafic-ultramafic magmatic events in the NT and SA. Eighteen events are recognised with three of these (~1810 Ma, ~1130 Ma,~520 Ma or younger) mineralised (Ni, Cu, Co, PGEs). Inset maps show the distribution of Proterozoic and Archaean rocks, mineral occurrences, large igneous provinces, time-space-event chart, and geophysical-elevation imagery.
