Mining activities take place in all of the above (depending on the mineral).
The Shivalik Hills are a mountain range in northern India and Pakistan. They are part of the Himalayas and are made up of sedimentary rocks. The Shivalik Hills are a major source of coal, limestone, and sandstone.
The Aravalli Range is a mountain range in northwestern India. It is the oldest mountain range in India and is made up of metamorphic rocks. The Aravalli Range is a major source of iron ore, bauxite, and manganese.
The Indo-Gangetic Plains are a vast plain in northern India and Pakistan. They are formed by the Indus and Ganges rivers and are made up of alluvial deposits. The Indo-Gangetic Plains are a major source of coal, iron ore, and natural gas.
The type of mineral that is mined in a particular area depends on the geology of the area. For example, the Shivalik Hills are a major source of coal because they are made up of sedimentary rocks that contain coal deposits. The Aravalli Range is a major source of iron ore because it is made up of metamorphic rocks that contain iron ore deposits. The Indo-Gangetic Plains are a major source of coal because they are made up of alluvial deposits that contain coal deposits.
