Aiding the Search for Diamonds in South Australia: Source and origin of Mesozoic kimberlite dyke swarms and their mantle samples.

Because of significant, yet tantalising, alluvial diamond discoveries in the Adelaide Hills and Flinders Ranges over more than 100 years, South Australia can be viewed to have considerable potential as a diamond producer. Yet this potential is unresolved because little is known about the occurrence and diamond content of the kimberlite source rocks that have carried the diamonds to the near surface and shed them into the weathering environment. This collaborative research project will use new uncommonly available samples provided by commercial diamond exploration to determine the structure , geochemistry and history of the mantle that underlies the Flinders Ranges and Adelaide Hills at depths between 40 and 250km.
