The paper pertains to the studies carried out on the eclogitic xenoliths of KL-2 kimberlite of Kalyandurg kimberlite cluster in south India. Petrographic studies revealed bi-mineralic and kyanite-bearing eclogitic xenoliths in KL-2 kimberlite. The bimineralic and kyanite-bearing eclogites of Kalyandurg KL-2 kimberlite pipe show variation in modal proportion of garnet, omphacite, clinopyroxene and kyanite. The paper reports discovery of native gold grains and Au-Pt alloy in the kyanite-bearing eclogite xenoliths of KL-2 kimberlite. The flaky gold grains occurring in the matrix of kyanite-bearing eclogite are homogeneous and two grains of Au-Pt alloy with Au and Pt in the proportion of 9.8:1.2 are also present. This is the first report of gold and gold-platinum alloy specs from eclogitic xenoliths of Indian kimberlites.

该论文涉及对印度南部 Kalyandurg 金伯利岩群 KL-2 金伯利岩的榴辉岩包体进行的研究。岩石学研究揭示了 KL-2 金伯利岩中的双矿物和含蓝晶石的榴辉岩包体。Kalyandurg KL-2 金伯利岩管的双矿物和含蓝晶石榴辉岩显示石榴石、绿辉石、单斜辉石和蓝晶石的模态比例变化。该论文报道了在 KL-2 金伯利岩的含蓝晶石榴辉岩包体中发现了天然金颗粒和 Au-Pt 合金。含蓝晶石榴辉岩基体中出现的片状金颗粒是均质的，还存在两种Au和Pt比例为9.8:1.2的Au-Pt合金颗粒。这是关于来自印度金伯利岩榴辉岩捕虏体的金和金铂合金规格的第一份报告。
