RAS question
Calcite deposits in Rajasthan are found in which areas?
Correct answer: (B) Udaipur and Rajsamand.
Calcite deposits in Rajasthan are found in Udaipur and Rajsamand, within the Aravalli region noted for this mineral occurrence.
Explanation
The correct pair is Udaipur and Rajsamand because Rajasthan's calcite deposits are associated with the Aravalli region across Udaipur, Rajsamand and Sirohi districts. Important deposits include Dhinkali, Gayphal and Rabcha in Udaipur district, and Belka Pahar and Khila in Sirohi district. The Rajsamand District Industrial Potential Survey, 2018-19 also lists calcite among the district's important minerals. Therefore, Udaipur and Rajsamand is the correct pair among the options.
Why the other options are wrong
- (A) Jaipur may have minor calcite occurrences, but Rajasthan's principal Aravalli calcite area includes Udaipur, Rajsamand and Sirohi, not Tonk.
- (C) Jodhpur and Jaisalmer are more closely associated with sandstone, whereas the mineral asked about here is calcite.
- (D) Kota and Bundi fall outside the principal Aravalli calcite area, and Kota is associated with limestone rather than calcite.
Concept
RAS questions on Rajasthan geography often use district-mineral pairings. To answer them, candidates need to know the spatial distribution of non-metallic minerals in the Aravalli region, not merely the mineral names.
