Mineral Distribution in India
• India is one of the most mineral-abundant countries in the world and has vast quantities of an ample diversity of minerals.
• The old hard rocks characterise the Indian subcontinent, and the orogenic architecture is prominent, which has enabled the development of practically all mineral types.
• The Gondwana rocks become the richest source in this setting, containing virtually all the known mineral species.
• Metal mineral deposits are mainly found on the crystalline basement of the peninsular plateau, with the non-metallic deposits being abundant in the alluvial plains.
• Its coal reserves are concentrated in the Damodar, Sone, the Mahanadi and Godavari valleys, with over 97 % of the reserves found there.
• The concentration of petroleum resources is no exception, as 40 per cent is found in Assam, 35 per cent in Gujarat, and 25 per cent in Mumbai High, all of which are offshore deposits in the basin of sediments in the Arabian Sea.
• Recent hydrocarbon discoveries were reported within the Krishna-Godavari and Kaveri basins.
