被麻粒岩相岩石(紫苏花岗岩—孔达岩群)所复盖的印度地盾高级变质区(大于30亿年),类似于澳大利亚和南部非洲的高级变质区,没有很丰富的矿产。在印度地盾已确定了三个原始大陆,即达瓦尔、辛格布姆和阿拉瓦利。达瓦尔的高级变质区具有很好的矿产潜力。喀拉拉和泰米尔纳德的条带状石英—磁铁矿床,是代表太古宙含铁建造的最早岩相,可与西格陵兰伊苏阿最老的条带状含铁建造对比。已注意到一些地方,有金和 The high-grade Indian metamorphic zone (more than 3 billion years) covered by granulite facies rocks (peridotite-kundafushi group), similar to the high-grade metamorphic zones of Australia and southern Africa, is not very rich in minerals. In the Indian Shield, three primitive continents have been identified: Daval, Singhbum and Aravali. The advanced metamorphic zone of Davar has good mineral potential. The banded quartz-magnetite deposits of Kerala and Tamil Nadu, the earliest lithofacies that represent Archean iron, are comparable to the oldest banded iron-bearing constructions in Issoua, West Greenland. Some places have been noticed, with gold and gold
