India is fortunate to have fairly rich and varied mineral resources.
(i) In peninsular plateau the reserves of coal, metallic minerals, mica and many other non-metallic minerals are found.
(ii) In the sedimentary rocks of Gujarat and Assam most of the petroleum deposits are found.
(iii) Rajasthan with the rock systems of the peninsula, has reserves of many nonferrous minerals.
(iv) The alluvial plains of north India are almost devoid of economic minerals.
(v) These variations in the distribution of minerals exist due to differences in the geological structure, process and the time involved in the formation of minerals.
