Rajasthan is India’s mineral powerhouse, rich in lead-zinc, marble, limestone, petroleum, lignite and dimensional stones. For RAS 2026, understanding mineral distribution, mining economy, and sustainable governance is crucial for both Prelims and Mains.

Rajasthan is one of India’s leading mineral-producing states, owing to its diverse geological formations such as the Aravalli Range (Archaean rocks), Proterozoic belts, Vindhyan sedimentary basins, and Thar desert structures. The state is rich in metallic minerals (lead-zinc, copper, silver), non-metallic minerals (marble, limestone, gypsum, phosphorite), energy minerals (lignite, petroleum, natural gas), atomic minerals (uranium), and dimensional stones. This mineral diversity makes Rajasthan a key pillar of India’s mining economy.

Mining is one of the major contributors to GSDP, royalty payments, the industrial sector, and the export sector of Rajasthan in the cement, ceramics, marble, granite, and metal industries. In the case of RPSC RAS 2026, the topic has been essential in the exam of Rajasthan Geography, Economic Development, Public Finance, Industrial Location, Environmental Governance, and Sustainable Development, hence being of great importance to both Prelims and Mains.

Mining plays a crucial role in:

• Rajasthan’s Gross State Domestic Product (GSDP)
• Royalty and non-tax revenue generation
• Employment creation (direct & indirect)
• Cement, ceramic, stone-processing and metal industries
• Export-oriented dimensional stone sector

For RPSC RAS 2026, Mineral Resources of Rajasthan is highly important under:

• Rajasthan Geography
• Economic Development of Rajasthan
• Industrial Location & Raw Material Base
• Public Finance (royalty revenue)
• Environmental Governance
• Sustainable Development

1. Geological Structure & Mineral Formation in Rajasthan

The mineral endowment in Rajasthan is highly linked to its complicated geological development that comprises Archaean crystalline rocks, Proterozoic formations, Vindhyan sedimentary basins and the Western desert basin. These rock systems control the distribution of metallic minerals, non-metallic minerals, energy resources, and building stones across the state. Understanding this geological framework is essential for Rajasthan Geography, mineral distribution mapping, and economic geology topics in RAS 2026.

Major Geological Systems of Rajasthan

1. Archaean & Aravalli System

• Oldest rock system.
• Composed of metamorphic and igneous rocks.
• Rich in copper, lead, zinc, silver and iron ore.
• Major metallic mineral belt of Rajasthan.

2. Dharwar Type Rocks

• Contain significant metallic mineral deposits.
• Economically important due to copper and lead-zinc ores.

3. Vindhyan Rock System

• Sedimentary rocks.
• Associated with limestone, sandstone, Kota stone.
• Important for the cement and building stone industry.

4. Western Desert Sedimentary Basin

• Hosts lignite, gypsum, petroleum, and natural gas.
• Economically important for energy resources.

RAS Insight: The Aravalli belt has predominantly metallic minerals, with non-metallic and energy minerals being predominantly found in the sedimentary formations.

2. Classification of Minerals in Rajasthan

The mineral resources of Rajasthan are quite diversified and economically important as they sustain the industry of cement, ceramics, metallurgy, energy, and construction. Minerals found in Rajasthan fall under the general group of metallic, non-metallic, energy, atomic, and building or dimensional stones based on their physical characteristics, their use in industry as well as their economic significance. It is a classification of RAS 2026 of Rajasthan Geography, economic development, and industrial location.

Major Categories of Minerals in Rajasthan

1. Metallic Minerals

• Contain metal content and are used for the extraction of metals.
• Include copper, lead, zinc, silver, iron ore, manganese, and gold.
• Mainly concentrated in the Aravalli belt.
• Form the backbone of base metal mining and smelting industries.

2. Non-Metallic Minerals

• Do not yield metals, but are industrially important.
• Include gypsum, phosphorite, limestone, feldspar, mica, fluorite, talc, and clay minerals.
• Used in cement, fertiliser, ceramic, chemical, and glass industries.
• Rajasthan ranks among the leading producers of several non-metallic minerals in India.

3. Energy Minerals

• Used as fuel or for power generation.
• Include lignite, petroleum, and natural gas.
• Found mainly in the Western Desert Basin (Barmer, Jaisalmer, Bikaner region).
• Critical for energy security and thermal power production.

4. Atomic Minerals

• Used in nuclear energy and strategic industries.
• Include uranium, thorium, and beryllium.
• Found in limited but important pockets across the state.
• Relevant for national energy policy and strategic mineral resources.

5. Building & Dimensional Stones

• Used in construction and decorative purposes.
• Include marble, granite, sandstone, Kota stone, and slate.
• Rajasthan is internationally famous for Makrana marble, Jalore granite, and Dholpur sandstone.
• Major contributor to export revenue and the stone-processing industries.

To prepare RAS, this classification can be useful in arranging the data on minerals to work on Prelims (objective questions on the types of minerals and their distribution) and to write structured answers in Mains about the utilisation of the minerals in industrial development, resource utilisation, and regional development.

3. Metallic Minerals of Rajasthan

The mining economy of Rajasthan is based on its metallic minerals, which are largely focused in the Aravalli-Delhi Fold Belt. The state is nationally significant in the base metals such as lead, zinc, silver and copper and also has deposits in iron ore, tungsten and gold. They are extremely relevant in RAS 2026 since these minerals support the metallurgical industries, electrical manufacturing, defence production, and alloy-based industries.

Major Metallic Minerals – Quick Overview

Key Analytical Points for RAS

• Lead–Zinc Belt is globally significant and operated largely by Hindustan Zinc Limited (HZL).
• Silver production occurs mainly as a by-product of lead-zinc processing.
• Khetri Copper Belt is one of India’s prominent copper zones.
• Degana Tungsten has strategic importance for defence manufacturing.
• Gold deposits in Banswara remain under exploration and limited extraction.

In the case of RAS Prelims, emphasis was made on major mining districts and mining-district maps. In the case of Mains, associate metallic minerals to the industrial location, export potential, royalty revenue and challenges to sustainable mining.

4. Non-Metallic Minerals of Rajasthan

Rajasthan cement, ceramic, fertilizer and building stone industries are based on non- metallic minerals. India is a major producer of marble, limestone, gypsum, rock phosphate, feldspar and various decorative stones, which are mainly produced by the state.
