RAS question
Rajasthan is the largest producer of feldspar in India. Major deposits are found in:
Correct answer: (B) Ajmer and Bhilwara.
Rajasthan's major feldspar deposits are found in Ajmer and Bhilwara, with Ajmer identified by the state Mines Department as the leading feldspar producer and Bhilwara among the other important producing districts.
Explanation
Rajasthan is the key state to remember for feldspar in the RAS mineral geography syllabus. The official Mines Department mineral profile says the state is a major producer of feldspar and has about 87.94 million tonnes of resources. Within Rajasthan, Ajmer is named as the leading producer, while Bhilwara is listed among the other important producing districts. This directly supports option B: Ajmer and Bhilwara. Major deposits are also placed in Ajmer, Bhilwara, Udaipur and Pali, and feldspar is used in ceramics, glass manufacturing, and as a filler in paints and plastics. So the logic is not just district recall; it links Rajasthan's mineral resource base with its industrial uses.
Why the other options are wrong
- (A) Kota and Bundi are associated with sandstone and basalt, not with the main feldspar-producing districts named for Rajasthan.
- (C) Ganganagar and Hanumangarh are alluvial-plain districts with no feldspar deposits, so they do not fit this mineral-deposit question.
- (D) Barmer and Jaisalmer are linked with petroleum rather than significant feldspar production, so they are not the relevant feldspar belt here.
Concept
This tests Rajasthan's mineral distribution, especially district-wise associations of non-metallic minerals. RAS repeats such questions because they connect physical geography with resource-based industries and district-level economic geography.
