Distribution of India's minerals and energy for UPSC — mineral belts, ores, coal types, oil fields, nuclear minerals, renewables and critical minerals.
SyllabusGS I · Distribution of key natural resources across the world, including South Asia and the Indian subcontinent
Prerequisites: Physiography of India · Geomorphology
The Hook: Lithium in the Hills of Reasi
In February 2023, the Ministry of Mines announced that the Geological Survey of India had established lithium inferred resources (G3 stage) of 5.9 million tonnes in the Salal-Haimana area of Reasi district, Jammu and Kashmir. Lithium is the heart of the batteries that power electric vehicles and store solar energy. Months later, in June 2023, the Ministry released a list of 30 critical minerals, and in January 2025 the Union Cabinet approved a National Critical Mineral Mission.
Why are some minerals found in the Himalayas, others only in the Peninsula, and oil only in certain basins? The answer lies in the rocks.
The Core Concept
A mineral is a naturally occurring substance with a definite chemical composition. An ore is a mineral deposit rich enough to be mined profitably. Geology decides the location:
| Rock / setting | Minerals typically found | Indian example |
|---|---|---|
| Ancient igneous and metamorphic rocks (Dharwar, Cuddapah systems) | Metallic ores — iron, manganese, copper, gold; mica | Peninsular plateau |
| Gondwana sedimentary basins | Coal (most of India’s reserves) | Damodar, Mahanadi, Godavari, Son valleys |
| Tertiary sedimentary rocks | Petroleum and natural gas (in anticlines and fault traps); tertiary coal | Assam, Gujarat, Mumbai High, Rajasthan |
| Weathering (residual) deposits | Bauxite (in laterite) | Amarkantak plateau, Odisha hills |
| Placer deposits (beach and river sands) | Monazite (thorium), ilmenite | Coasts of Kerala and Tamil Nadu |

| Mineral | Key facts | Major areas |
|---|---|---|
| Iron ore | Magnetite — finest, up to 70% iron, magnetic; haematite — most important industrial ore, 50–60% iron (NCERT) | Odisha–Jharkhand belt (Badampahar in Mayurbhanj and Kendujhar; Gua and Noamundi in Singhbhum); Durg–Bastar–Chandrapur belt (Bailadila hills, Chhattisgarh — high-grade haematite exported via Visakhapatnam); Ballari–Chitradurga–Chikkamagaluru–Tumakuru belt (Kudremukh — ore slurry sent by pipeline to Mangaluru port); Maharashtra–Goa belt (exported through Marmagao) |
| Manganese | Used in making steel and ferro-manganese alloy | Odisha, Karnataka, Madhya Pradesh (Balaghat), Maharashtra (Nagpur, Bhandara) |
| Bauxite | Ore of aluminium; formed by decomposition of rocks rich in aluminium silicates — found in laterite | Amarkantak plateau, Maikal hills, Bilaspur–Katni plateau; Panchpatmali deposits in Koraput (Odisha) |
| Copper | Good conductor; used in electrical and electronics industries | Malanjkhand (Balaghat, MP), Khetri (Jhunjhunu, Rajasthan), Singhbhum (Jharkhand) |
| Gold | — | Kolar (Karnataka; closed), Hutti (Karnataka) |
Non-metallic minerals
| Mineral | Key facts | Major areas |
|---|---|---|
| Mica | Splits into thin sheets; excellent di-electric strength — used in electrical and electronic industries | Northern edge of the Chotanagpur plateau — the Koderma–Gaya–Hazaribagh belt; Ajmer (Rajasthan); Nellore (Andhra Pradesh) |
| Limestone | Basic raw material of the cement industry; also used in iron-smelting | Sedimentary rocks in most States |
Conventional energy
Coal — types by carbon content (highest to lowest):
| Type | Features |
|---|---|
| Anthracite | Highest-quality hard coal; highest carbon |
| Bituminous | Most widely used commercially; high-grade bituminous (coking) coal is used in iron-smelting |
| Lignite | Low-grade brown coal; high moisture — Neyveli (Tamil Nadu) |
| Peat | Decaying plants; low carbon, low heat |
| Coal formation | Age (NCERT) | Where |
|---|---|---|
| Gondwana coal | About 200 million years | The bulk of reserves; Damodar valley (Jharia, Raniganj, Bokaro), and the Godavari, Mahanadi, Son and Wardha valleys |
| Tertiary coal | About 55 million years | North-east — Meghalaya, Assam, Arunachal Pradesh, Nagaland |
Petroleum and natural gas: found in anticlines and fault traps in sedimentary rocks.
| Region | Fields |
|---|---|
| Assam | Digboi (India’s oldest oil-producing region), Naharkatiya, Moran |
| Gujarat | Ankleshwar, Kalol |
| Offshore Maharashtra | Mumbai High |
| Rajasthan | Barmer basin (Mangala field) |
| East coast | Krishna–Godavari basin (natural gas) |
Nuclear minerals and India’s three-stage programme:
- Uranium occurs in the Dharwar rocks — the Singhbhum copper belt (Jaduguda, Jharkhand) and parts of Rajasthan, Chhattisgarh and Maharashtra.
- Thorium comes from monazite in the beach sands of the Kerala and Tamil Nadu coasts. India’s large thorium reserves explain its strategy.
- Three stages (Homi Bhabha): (1) pressurised heavy water reactors using natural uranium; (2) fast breeder reactors using plutonium; (3) reactors using thorium. The Prototype Fast Breeder Reactor is at Kalpakkam, Tamil Nadu.
Non-conventional energy
| Source | Favourable locations |
|---|---|
| Solar | High-insolation, low-cloud regions — Rajasthan (Bhadla Solar Park, Jodhpur), Gujarat |
| Wind | Coastal and pass locations — Tamil Nadu (Muppandal), Gujarat, Maharashtra, Karnataka, Rajasthan |
| Tidal | Large tidal range — Gulf of Khambhat, Gulf of Kachchh, Sundarbans |
| Geothermal | Hot springs — Puga valley (Ladakh), Manikaran (Himachal Pradesh) |
| Biomass / biogas | Rural areas with crop residue and dung |
Targets: at COP26 (Glasgow, November 2021) India announced the Panchamrit, including 500 GW of non-fossil electricity capacity by 2030 and net zero by 2070. India’s updated NDC (August 2022) commits to about 50% of cumulative installed electric power capacity from non-fossil sources by 2030.
Policy framework
- Mines and Minerals (Development and Regulation) Act, 1957 — the core law. The 2015 amendment made auction the method of allotting mineral concessions and created District Mineral Foundations for mining-affected people. The 2023 amendment removed six minerals, including lithium, from the list of atomic minerals (opening them to private exploration) and empowered the Centre to auction concessions for specified critical and strategic minerals.
- Critical minerals: list of 30 released by the Ministry of Mines (June 2023); National Critical Mineral Mission approved in January 2025.
- Rights and consent: in Orissa Mining Corporation v. Ministry of Environment and Forests (April 2013), the Supreme Court left it to the gram sabhas of the Niyamgiri hills to decide whether bauxite mining would affect their religious and cultural rights; they rejected the project.
Memory Anchors
Iron ore belts: “Old Dogs Bark More” → Odisha–Jharkhand · Durg–Bastar–Chandrapur · Ballari–Chitradurga · Maharashtra–Goa.
Coal by quality: “A Big Lump of Peat” → Anthracite > Bituminous > Lignite > Peat.
Copper trio: “Kings Make Swords” → Khetri (Rajasthan) · Malanjkhand (MP) · Singhbhum (Jharkhand).
Nuclear pairing: Jaduguda = Jharkhand uranium; Kerala sands = thorium (monazite); Kalpakkam = fast breeder.

Practice
Prelims
Consider the following pairs:
| Mining area | Mineral |
|---|---|
| 1. Khetri | Copper |
| 2. Kudremukh | Bauxite |
| 3. Jaduguda | Uranium |
| 4. Koderma | Manganese |
How many of the pairs given above are correctly matched?
Solution
Pair 1 is correct — Khetri (Rajasthan) is a copper area. Pair 3 is correct — Jaduguda (Jharkhand) is India’s best-known uranium mine. Pair 2 is wrong — Kudremukh (Karnataka) is an iron ore area. Pair 4 is wrong — Koderma (Jharkhand) is famous for mica. So two.
Answer: B
Consider the following statements:
- Most of India’s coal reserves occur in the Gondwana formations of the Peninsula, such as the Damodar valley.
- Tertiary coal is found mainly in the north-eastern States.
- Lignite is mined at Neyveli in Tamil Nadu.
Which of the statements given above are correct?
Solution
All three are correct. Gondwana coal (about 200 million years old) forms the bulk of India’s reserves in the Damodar, Mahanadi, Godavari, Son and Wardha valleys. Tertiary coal (about 55 million years old) occurs in Meghalaya, Assam, Arunachal Pradesh and Nagaland. Neyveli is India’s best-known lignite field.
Answer: D
India’s thorium resources are associated mainly with
Solution
Thorium is extracted from monazite, a placer mineral concentrated in the beach sands of Kerala and Tamil Nadu. India’s large thorium resources are the reason the third stage of its nuclear programme is designed around thorium. Bauxite, coal and mica are unrelated to thorium.
Answer: A
Mains
Why is India’s mineral wealth concentrated in the Peninsular plateau? Examine why this wealth has often failed to bring prosperity to the regions where it is found.
Solution
Introduction: India’s metallic minerals and most of its coal lie in the Peninsular plateau — in Jharkhand, Odisha, Chhattisgarh, Karnataka and Goa — while the alluvial plains have few minerals.
Body — why the Peninsula:
- Ancient igneous and metamorphic rocks (Dharwar and Cuddapah systems) host iron ore, manganese, copper, gold and mica.
- Gondwana sedimentary basins in rift valleys (Damodar, Mahanadi, Godavari) hold most coal.
- Long weathering formed laterite with bauxite.
- The Northern Plains, by contrast, are buried under thick alluvium.
Body — why prosperity has lagged:
- Resource curse: raw minerals are exported out of the region; value addition happens elsewhere.
- Displacement: mining overlaps with forests and Scheduled Areas; rehabilitation has been weak.
- Environment: deforestation, water pollution, dust and health costs fall on locals.
- Governance: illegal mining, weak local institutions, conflict and Left-wing extremism in parts of the belt.
Body — corrective steps:
- District Mineral Foundations (MMDR Amendment, 2015) to fund local welfare.
- Gram sabha consent in Scheduled Areas — the Niyamgiri judgment (2013); PESA and the Forest Rights Act.
- Auction-based allocation for transparency; local processing and skilling.
Conclusion: Geology made the Peninsula mineral-rich; only inclusive governance — local benefit-sharing, consent and environmental safeguards — can make its people prosperous.
