The 'Chotanagpur Plateau' is rich in mineral resources and is composed primarily of which rock formations?

💡 Solution & Explanation

The Chotanagpur Plateau is composed predominantly of ancient Archean granites and gneisses, interspersed with Dharwarian rock systems that host massive deposits of coal, iron ore, mica, and bauxite. Recent sedimentary alluvial deposits characterize the Indo-Gangetic plains to the north. Cretaceous basaltic lava flows form the Deccan Traps plateau region further west and south. The plateau covers parts of Jharkhand, Chhattisgarh, and West Bengal.
