It is subdivided into Maharashtra Plateau, Karnataka Plateau, and Rayalaseema & Telangana Plateau. The Deccan Traps in the north west were formed by multiple layers of igneous rocks laid down by basaltic lava flows following a massive volcanic eruption that occurred during the end of the cretaceous period. The underlying bed consists of granite and sedimentary rocks formed during the precambrian era and the formation of Gondwana.
