Basement. The Vindhyan Supergroup is classified into two fundamental strata, lower and upper Vindhyan, with a large unconformity representing 500 million years interval between the strata. Within each stratum, it is further categorized into major groups. The lower Vinhydan comprises the Semri Group while the upper Vinhyan consists of the Kaimur Group, Rewa Group, and Bhander Group. The earliest sedimentation forming the lower Vindhyan can be traced back to Paleoproterozoic and stopped somewhere around early Mesoproterozoic (~1,721 Ma to 1,600 Ma). Sedimentation forming the upper Vindhyan resumed again in the Mesoproterozoic and ceased in Neoproterozoic. Vindhyan Supergroup portrayed transitional to shallow marine depositional environment, such as

Similar to other Purana basins, the Marwar Supergroup is less deformed and unmetamorphosed. The Marwar Supergroup is classified into three major groups: the lower Jodhpur Group, the middle Bilara Group, and the upper Nagaur Group.

The
Vindhyan Basin is located on the southeastern side of the Aravalli Mountain Range where its formation is believed to be associated to the large downwarp of the crust after Delhi Orogeny. It spans an area of about 104,000 km in the northwestern part of India overlying on the Archean Bhilwara
