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.

由于100多年来在阿德莱德山和弗林德斯山脉发现了大量的、诱人的冲积钻石，南澳可以被视为具有相当大的钻石生产潜力。然而，这一潜力尚未得到解决，因为人们对金伯利岩源岩的产状和金刚石含量知之甚少，金伯利岩源岩将金刚石带到近地表，并将它们带入风化环境。这项合作研究项目将使用商业钻石勘探提供的罕见新样本，以确定弗林德斯山脉和阿德莱德山地下40至250公里深处的地幔的结构、地球化学和历史。
