Progress in the exploration and research of primary diamond deposits in China
The"National Diamond Exploration Field Seminar"held by China Geological Survey in Suzhou,Anhui in 2013 kicked off a new round of primary diamond deposits exploration in China.In the past decade,a series of new progress in the exploration and research of primary diamond deposits have been made:the new batch of primary diamond resources identified in Langan,Anhui and Wafangdian,Li-aoning further enhanced domestic supply ability of diamond resoureces.The Ⅵ diamond mineralization belt in Liaoning,the Pingyi-Feixian diamond mineralization belt in Shandong and new prospecting clues in other regions will expand the exploration spaces of primary diamond deposits.The comprehensive explora-tion methods such as tectonic analysis-3D modeling-engineering verification,and high-resolution remote sensing information extraction are new exploring ideas for deep exploration and the discovery of hidden rock bodies.New insights in the genesis of diamond-bearing rock bodies,the emplacement model of kim-berlite(potassium magnesium lamprophyre),and the study of diamond source area have been acquired.The chronological studies have shown that the mineralization of diamond-bearing parent rock in China ex-tends from the Paleozoic to the late Mesozoic,which embodies the feature of multi-stage metallogenesis.Based on the progress and new problems in diamond exploration and research in the past decade,the sug-gestions for future exploration and research of primary diamond deposits is also proposed in the paper.
