The rocks of Dharwar system are found over the rocks of Archean era. In some regions, two types of rocks – Archean as well as Dharwar are found nearby each other. The metamorphism and eroison of the rocks of Archean age has been taking place. During the process of this erosion, the deposits which took place, changed into the rocks of Dharwar system. Some of the rocks are badly deformed and transmuted, while others are formed by recently deposited alluvium that has yet to undergo diagenesis. Minerals deposits of great variety are found in the subcontinent in huge quantity.
