Composition, structure and evolution of the lithospheric mantle beneath southern Africa: improving area selection criteria for diamond exploration

The project will provide new insights into the detailed structure of the deep Earth (to about 250 km) and identify and predict zones of weakness that could focus kimberlite magmas that carry diamonds to the surface. A better understanding of the nature and location of these structures will lead to improved models for diamond exploration, enhancing the prospect of finding new deposits in Australia and abroad. Innovations in integrating information from geochemistry and geophysics, development of 3D imaging techniques, and extrapolation to past geological scenarios will provide new exploration tools, and also maintain our high international profile in research relevant to the National Priority on Developing Deep Earth Resources.
