The geological setting of the Cairn oil discovery in Mangla, Rajasthan, is characterized by the Thar Desert's sedimentary basins, specifically the Barmer Basin. This area primarily consists of sedimentary rocks formed during the Jurassic to Cretaceous periods, which contain significant hydrocarbon reservoirs. The presence of source rocks, reservoir rocks, and sealing formations in this region has contributed to the successful extraction of oil by Cairn Energy.
