Mineral Wealth of India

• Chota Nagpur Plateau: This vast plateau in eastern India is exceptionally rich in various minerals, earning it the moniker 'Treasure Trove of Minerals'. It accounts for a significant portion of India's mineral production. Key minerals found here include coal, iron ore, copper, mica, bauxite, manganese, limestone, and dolomite.
• Formation of Petroleum: Petroleum (crude oil) and natural gas are primarily formed from the remains of ancient marine organisms (plankton and algae) that were buried under layers of sediment and rock over millions of years. This process occurs under conditions of high temperature and pressure, typically within sedimentary rocks. Therefore, the statement that petroleum is formed from igneous rocks is incorrect. Igneous rocks are formed from molten magma or lava.
• Jharkhand as a Mineral-Rich State: Jharkhand is indeed one of India's most mineral-rich states. It holds substantial reserves of coal (particularly the Jharia coalfield), iron ore, copper, mica, bauxite, uranium, and other valuable minerals. Its mineral resources play a crucial role in the country's industrial landscape.
