The almost complete absence of basement outcrop or surface expression of mineralisation is the prime impediment to mineral exploration in the Gawler Craton of South Australia, and large areas elsewhere in Australia (Fig. 1). To explore in these covered terranes, we need high quality regional information, plus tools and techniques that allow us to better utilise the limited direct geological information from buried rocks. Analysis of potential-field data is one of the most common and cost-effective ways of inferring hidden geology. There are high quality aeromagnetic data available over most of the actively explored areas of Australia, and it is hoped that more closely-spaced ground gravity measurements, together with improvements in airborne gravity and airborne gravity gradiometer methods, will in the future raise the standard of gravity coverage to that of the magnetics.
