🪨 I. What are Minerals?

Minerals are naturally occurring substances with a definite chemical composition.

📌 Characteristics:

• Found in varied forms (solid, liquid, gaseous)

• Non-renewable

• Unevenly distributed across the Earth

---

🧭 II. Modes of Occurrence of Minerals

1. In igneous and metamorphic rocks – e.g., granite, where minerals occur in cracks and crevices

2. In sedimentary rocks – Formed through deposition (e.g., limestone)

3. In alluvial deposits – e.g., gold, tin, platinum (found in riverbeds)

4. As ocean water – e.g., common salt, magnesium

🧱 III. Types of Minerals

A. Metallic Minerals

• Contain metal elements

• Further divided into:

  • Ferrous Minerals (contain iron): Iron ore, manganese

  • Non-Ferrous Minerals (do not contain iron): Copper, bauxite

B. Non-Metallic Minerals

• Do not contain metals

• Examples: Mica, limestone, gypsum

⛏️ IV. Major Minerals and Their Distribution

🪨 1. Iron Ore

• Backbone of industrial development

• Types: Magnetite (best quality), Hematite (most used)

• Found in Jharkhand, Odisha, Chhattisgarh, Karnataka

⚙️ 2. Manganese

• Used in making steel and fertilizers

• States: Odisha, Maharashtra, Karnataka, MP

🟠 3. Bauxite

• Main ore of aluminium

• Found in Odisha, Gujarat, Jharkhand, Maharashtra

🔋 4. Copper

• Used in electrical industries

• States: Rajasthan, MP, Jharkhand

🌟 5. Mica

• Excellent insulator; used in electricals

• Found in Jharkhand, Andhra Pradesh, Rajasthan

⚡ V. Energy Resources: Types and Importance

🔌 A. Conventional Sources

• Widely used and exhaustible

1. Coal

• Most abundant fossil fuel in India

• Types: Peat, Lignite, Bituminous, Anthracite

• Found in Jharkhand, WB, Odisha, Chhattisgarh

2. Petroleum

• Used for transport, industry, etc.

• Major oil fields: Mumbai High, Assam, Gujarat, Digboi

3. Natural Gas

• Cleaner fuel than coal or petroleum

• Found in Mumbai High, KG Basin (AP)

4. Electricity

• Two types:

  • Hydel Power (dams): Himachal, Uttarakhand, Kerala

  • Thermal Power (coal/oil based): Jharkhand, UP, Maharashtra

---

🔋 B. Non-Conventional Sources

• Renewable and environment-friendly

---

🛡️ VI. Conservation of Minerals and Energy Resources

✅ Need for Conservation:

• Minerals are non-renewable

• Energy demand is increasing rapidly

• Prevent environmental degradation

🌿 Methods:

• Use of alternative energy sources

• Recycling of metals

• Promoting energy-efficient practices

• Strict implementation of mining regulations

---

📝 VII. Important Terms

---

📌 Summary

• Minerals and energy are vital for development but are limited in supply.

• India is rich in diverse mineral resources, unevenly spread.

• Rising energy needs demand conservation and eco-friendly alternatives.

• Emphasis on renewables is the way forward.
