Which of the following mineral resources is extracted in commercial quantities from the Makum coalfield located in the Tinsukia district of Assam?

💡 Solution & Explanation

The Makum coalfield in Assam contains extensive reserves of Tertiary-age coal characterized by high sulfur and low ash content, mined extensively for industrial applications. Other resources such as metallic iron ore and bauxite are predominantly found in peninsular Indian cratonic formations rather than Assam's sedimentary basin. Coal mining in this region dates back to the British colonial era with the establishment of the Assam Railway and Trading Company.
