Consider the following statements: 1. The peninsular rocks of India contain most of the reserves of coal, metallic minerals, mica and many other non-metallic minerals. 2. Sedimentary rocks on the western and eastern flanks of the peninsula, in Gujarat and Assam have most of the petroleum deposits. 3. Rajasthan with the rock systems of the peninsula, has reserves of many non-ferrous minerals. Which of the above statement are correct?

The correct answer is 1, 2 a nd 3 only . Key Points Minerals Distribution in India India is richly endowed with mineral resources. Explorations have found over 20,000 known mineral deposits and recoverable reserves of more than 60 minerals. 11 states account for 90 % of the total number of operational mines (Andhra Pradesh, Orrisa, Chhattisgarh, Jharkhand, West Bengal, Maharashtra, Tamil Nadu, Gujarat, Madhya Pradesh, Rajasthan, and Karnataka). India is fortunate to have fairly rich and varied mineral resources. The peninsular rocks of India contain most of the reserves of coal, metallic minerals, mica and many other non-metallic minerals. Hence, Statement 1 is correct. Sedimentary rocks on the western and eastern flanks of the peninsula, in Gujarat and Assam, have most of the petroleum deposits. Hence, Statement 2 is correct. Rajasthan with the rock systems of the peninsula has reserves of many non-ferrous minerals. Hence, Statement 3 is correct. The vast alluvial plains of north India are almost devoid of economic minerals. These variations exist largely because of the differences in the geological structure, processes and time involved in the formation of minerals.
