The Deccan Plateau (/ˈdɛkən/ DEK-ən ) or Peninsular Plateau, is a plateau that extends over an area of 422,000 km (163,000 sq mi) on the southern part of the Indian subcontinent. The plateau forms the bulk of the Deccan Peninsula, and stretches from the Satpura and Vindhya ranges in the north to the northern fringes of Tamil Nadu in the south. It is bound by the Eastern and the Western Ghats mountain ranges on the sides, which separate the region from the Eastern and Western Coastal Plains respectively. The plateau covers most of the Indian states of Andhra Pradesh, Karnataka, Maharashtra, and Telangana, excluding their coastal regions, and includes minor portions of Kerala and Tamil Nadu.
The plateau is marked by rocky terrain with an average elevation of about 600 m (2,000 ft). It is subdivided into Maharashtra Plateau, Karnataka Plateau, and Rayalaseema and Telangana Plateau. The Deccan Traps in the northwest were formed by multiple layers of igneous rock deposited by basaltic lava flows following a massive volcanic eruption occurred at the end of the Cretaceous period (66 mya). The underlying bed consists of granite and sedimentary rocks formed during the Precambrian era and the formation of Gondwana.
