The Vindhyan system of rocks is known for the production of which of the following?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. Limestone.
The Vindhyan system of rocks, stretching from Rajasthan to Bihar, is primarily composed of sedimentary rocks like limestones, sandstones, and shales. It is the most significant source of high-quality limestone in India, which is the backbone of the cement industry. These rocks are also famous for yielding ornamental building stones (like those used in the Red Fort) and are unique for being largely devoid of metalliferous minerals but rich in industrial raw materials.
Other options:
-
Manganese: Primarily found in the Dharwar system and Sausar series of rocks, notably in regions like Odisha, Karnataka, and Madhya Pradesh.
-
Iron ore and coal: Iron ore is mostly associated with the Dharwar system, while coal is found in the Gondwana rock system of the Damodar valley.
-
Bauxite: This ore is typically found in tertiary deposits and laterite rocks associated with plateau regions like Amarkantak and the Panchpatmali hills.
