3D inversion of potential field data from the Olympic Cu-Au province

The absence of basement outcrop and the nearly complete lack of surface expression of mineralisation in the Olympic Cu-Au province is the major impediment to mineral exploration in the province. In such circumstances, analysis of potential field data is one of the usual ways of inferring hidden geology, as high-quality datasets, especially aeromagnetic data, are available for most of the actively explored areas of Australia. Quantitative interpretation of potential field data principally involve 2D forward modelling of profiles, or sections, by skilled interpreters but it can be difficult, and time-consuming, to correctly track structure and geology from one section to the next should one wish to create a 3D model of the geology. To alleviate this problem, we have used a modification of the methods of Li and Oldenburg (1996 & 1998), constrained by known geological information, to give geologically and geophysically consistent solutions to the possible distributions of sources giving the magnetic and gravitational fields observed in a region about Olympic Dam.
