India is fortunate to have fairly rich and varied mineral resources. However, these are unevenly distributed.
(i)Broadly speaking, peninsular rocks contain most of the reserves of coal, metallic minerals, mica and many other non-metallic minerals.
(ii)Sedimentary rocks on the western and eastern flanks of the peninsula, in Gujarat and Assam have most of the petroleum deposits.
(iii)Rajasthan with the rock systems of the peninsula, has reserves of many non-ferrous minerals.
(iv)The vast alluvial plains of north India are almost devoid of economic minerals.
(v)These variations exist largely because of the differences in the geological structure, processes and time involved in the formation of minerals.
