RAS question
Kota Stone, a fine-grained limestone used for flooring, is quarried in:
Correct answer: (B) Kota and Jhalawar.
Kota Stone is a fine-grained limestone quarried mainly in the Kota and Jhalawar districts of Rajasthan.
Explanation
Kota Stone is a fine-grained variety of limestone used widely for flooring because it is durable, naturally textured and relatively affordable. The cited Rajasthan State Pollution Control Board document supports the location point directly: it describes Kota and Jhalawar districts of Rajasthan as areas with abundant splittable decorative-grade flooring limestone, and adds that the major deposits are in Kota district, which is why the stone is known as Kota Stone. That is why the Rajasthan geography answer is not simply a generic limestone belt, but specifically Kota and Jhalawar, with Kota carrying the stronger identity of the deposit.
Why the other options are wrong
- (A) Makrana is associated with marble, so it does not identify the main quarry belt for Kota Stone.
- (C) Jodhpur is known for sandstone, whereas Kota Stone is the flooring limestone linked to Kota and Jhalawar.
- (D) Dholpur is known for red sandstone, not for the main Kota Stone quarrying area.
Concept
This tests Rajasthan's mineral-resource geography, especially the district-wise association of building stones. It recurs in RAS because such questions connect physical resources with well-known regional industrial identities.
