India is blessed with a varied range of mineral resources owing to its diverse geological structure. These mineral resources form the essential bedrock for the industrial development of the country. Throughout India, minerals exhibit concentration in three extensive belts, with occasional isolated occurrences in certain regions.

MINERAL DISTRIBUTION

• India stands among the world's wealthiest nations in terms of mineral resources. 
• Its internal structure, composed of ancient hard rocks, hosts a diverse array of minerals, particularly in the Gondwana rocks. 
• The majority of metallic minerals in India are situated in old crystalline rocks on the peninsular plateau. 
• Notably, over 97 percent of coal reserves are concentrated in the Damodar, Sone, Mahanadi, and Godavari valleys. 
• Additionally, petroleum reserves are found in the sedimentary basins of Assam, Gujarat, and Mumbai High, located offshore in the Arabian Sea. 
• Recent discoveries of new reserves have been made in the Krishna-Godavari and Kaveri basins. 
• The major mineral resources are predominantly situated east of a line extending from Mangalore to Kanpur.

The North Eastern Plateau Region:

• The North Eastern Plateau Region encompasses Chhotanagpur (Jharkhand), the Odisha Plateau, West Bengal, and parts of Chhattisgarh. 
• This region is rich in a diverse range of minerals, making it a significant contributor to India's mineral wealth. 
• Notable minerals found in this belt include iron ore, coal, manganese, bauxite, and mica. 
• The presence of these resources has played a pivotal role in the industrial development of the region, particularly in sectors such as steel production, energy generation, and manufacturing.

The South-Western Plateau Region:

• Stretching through Karnataka, Goa, and the uplands of Tamil Nadu and Kerala, the South-Western Plateau Region is characterized by abundant deposits of bauxite and ferrous metals. 
• This belt also boasts high-grade iron ore, manganese, and limestone resources.
• However, it is devoid of coal deposits, with Neyveli lignite being the exception. 
• While the mineral deposits in this region are not as diverse as those in the north-eastern belt, they have significantly contributed to the economic development of the states involved. Kerala, in particular, stands out with monazite and thorium deposits alongside bauxite clay, while Goa is renowned for its iron ore deposits.

The North-Western Region:

• The North-Western Region, aligned with the Dharwar system of rocks along the Aravali in Rajasthan and parts of Gujarat, is characterized by its rich mineral deposits. 
• Copper and zinc, historically important minerals, are found in abundance in this region. Rajasthan stands out for its wealth in building materials such as sandstone, granite, and marble. 
• Additionally, large deposits of gypsum and Fuller's earth contribute to the mineral diversity of the region. 
• The cement industry in this area relies on dolomite and limestone as crucial raw materials. Gujarat, on the other hand, is recognized for its significant oil and gas reserves, while both Gujarat and Rajasthan are endowed with abundant salt reserves, further adding to the mineral richness of the North-Western Region.

Other Belts:

1. The Himalayan Belt:

• The Himalayan Belt, while generally deficient in metallic minerals, harbors valuable mineral pockets within its vast expanse. 
• In the Himalayas, one can find minerals such as copper, lead, zinc, bismuth, bauxite, antimony, nickel-cobalt, tungsten, precious stones, gold, silver, gypsum, limestone, and dolomite. 
• Despite its overall scarcity in metallic minerals, the Himalayan Belt stands out for its unique pockets of diverse and economically significant mineral resources.

2. The Central Belt:

• The Central Belt of India comprises the states of Chhattisgarh, Madhya Pradesh, Andhra Pradesh, Telangana, and Maharashtra. 
• This belt is characterized by a diverse array of minerals, making it the country's second-largest mineral belt. 
• Bauxite, manganese, limestone, marble, uranium, coal, gems, and mica are among the rich mineral resources found in this region. 
• The presence of such a wide range of minerals contributes significantly to the industrial and economic development of the states within the Central Belt, playing a crucial role in various sectors, including mining, manufacturing, and construction.

3. Indian Ocean Belt:

• The Indian Ocean Belt, situated along the continental shelf of the Arabian Sea and the Bay of Bengal, is a region abundant in mineral oil and natural gas. 
• The seabed in this belt holds high-grade nodules containing manganese, phosphate, barium, aluminum, silicon, iron, titanium, sodium, potassium, chromium, monazite, ilmenite, magnetite, and garnet. 
• These mineral resources, extracted from the depths of the ocean, contribute to India's energy security and industrial needs. 
• The exploration and utilization of minerals from the Indian Ocean Belt represent a unique and technologically advanced facet of India's mineral resource management.
