Examine the physiographic divisions and mineral wealth of the Chota Nagpur Plateau: Statement I: The Chota Nagpur Plateau is a prime example of an uplifted peneplain composed largely of ancient Precambrian crystalline rocks. Statement II: It is exceptionally rich in metallic and non-metallic mineral resources, earning it the title of the mineral heartland of India. Which of the following is correct?

💡 Solution & Explanation

Both statements correctly describe the structural evolution and economic prominence of the Chota Nagpur Plateau spanning Jharkhand, Odisha, and West Bengal. Long-term erosion reduced this ancient continental block into a rolling peneplain before tectonic uplift rejuvenated its relief features. The region hosts massive deposits of iron ore, coal, mica, bauxite, and copper within its complex Dharwarian rock systems. This mineral concentration drives heavy industrial manufacturing across eastern India.
