Indian Geography ā Indian Geography ā RESOURCES & ECONOMIC GEOGRAPHY ā RESOURCES & ECONOMIC GEOGRAPHY ā Mineral Resources | Author: admin | Feb 11, 2026
1. Introduction Unit 5.1 covers the distribution of metallic and non-metallic mineral belts in India. Metallic minerals include iron ore, manganese, bauxite, copper, and others, while non-metallic include limestone, mica, gypsum, and others. These minerals are concentrated in specific geological belts due to ancient rock formations and tectonic history. This unit focuses on major belts, mining locations, and their economic importance for industries and exports.
2. Significance This unit is crucial for 2026 exams ā it carries 6ā10 marks in Prelims (MCQs on mineral belts, states, major mines) and 8ā12 marks in Mains (analytical on distribution, industrial linkage, import dependence). SSC/RRB/JE test factual recall (belts, mines). Linkages to current: Critical minerals push (lithium, rare earths), Make in India/PLI schemes, mining reforms 2025ā2026. Master for high scores in GS1 (resources) and GS3 (economy, industry).
3. Chronological/Geological Timeline
- Precambrian (Archaean-Proterozoic): Major metallic deposits form (iron ore in Singhbhum, Bailadila).
- Gondwana period: Coal and some non-metallics (limestone) deposited.
- 19th century: British colonial mining begins (iron ore, manganese).
- Post-1947: National Mineral Policy; PSUs formed (SAIL, NMDC).
- 1990sā2010s: Liberalization; FDI in mining.
- 2020sā2026: Critical Minerals Mission; mining reforms; auctions for lithium/rare earths.
4. Concept Deep Dive Metallic belts: Formed in ancient shields (Dharwar, Singhbhum, Bailadila).
- Iron ore: Singhbhum (Jharkhand), Bailadila (Chhattisgarh), Bellary-Hospet (Karnataka).
- Manganese: Odisha, Karnataka, Maharashtra.
- Bauxite: Odisha, Gujarat, Maharashtra. Non-metallic: Sedimentary/metamorphic rocks.

- Mica: Bihar, Jharkhand, Rajasthan. Distribution controlled by geology: Archaean rocks ? iron/manganese; sedimentary ? limestone. (Ref: NCERT Class 10 Contemporary India Ch. 5 "Minerals & Energy"; Majid Husain Ch. 5 "Mineral Resources"; Savindra Singh Ch. 14 "Mineral Deposits"; Oxford Atlas for mineral belts).

- Non-Metallic Minerals: Non-metal (limestone, mica, gypsum).
- Ore: Mineral deposit with extractable metal.
- Singhbhum Belt: Major iron ore belt in Jharkhand.
- Bailadila Range: High-grade iron ore in Chhattisgarh.
- Bellary-Hospet: Iron ore belt in Karnataka.
- Mica Belt: Bihar-Jharkhand-Rajasthan.
- Limestone Belt: Rajasthan, MP, AP.
