Major Mineral Belts & The Chota Nagpur Plateau
India's non-fuel mineral resources are geographically distributed across distinct metallogenic provinces associated with Pre-Cambrian crystalline shields. The Chota Nagpur Plateau, spanning Jharkhand, Odisha, and West Bengal, is known as the 'Ruhr of India' due to its immense reserves of high-grade hematite iron ore, bauxite, copper, and metallurgical coal. The South-Western belt encompasses Karnataka and Goa, rich in Dharwar system iron ores (such as Kudremukh and Bellary-Hospet) and manganese. The North-Western belt along the Aravalli range in Rajasthan holds major reserves of non-ferrous polymetallic deposits, including lead-zinc ores at Zawar, marble, gypsum, and copper at Khetri. Additionally, the Central belt covering Madhya Pradesh, Chhattisgarh, and Maharashtra yields vital bauxite, manganese, and limestone.
Key Concepts & Examination Highlights
- The Chota Nagpur Plateau is often termed the 'Ruhr of India' because of its concentration of coal, iron ore, and heavy mineral industries.
- The Singhbhum Shear Zone in Jharkhand is renowned for copper deposits and uranium mining at Jaduguda.
- The Zawar mines in the Udaipur district of Rajasthan are India's principal source of lead, zinc, and silver ores.
- Bailadila in the Dantewada district of Chhattisgarh produces exceptionally high-grade hematite iron ore exported via Visakhapatnam port.
