RAS question
In Rajasthan mineral geography, which district is identified as the leading producer of marble?
Correct answer: (A) Rajsamand.
Rajsamand is identified as Rajasthan's leading marble-producing district, with the official Rajasthan Tourism page calling it the largest marble-producing district in the country.
Explanation
Marble is treated in the mineral notes as a building-stone mineral and as a metamorphic rock formed from limestone. The question is not asking for every marble-bearing area or for a famous marble variety; it asks for the district identified with leading production. On that point, Rajsamand is singled out. The official Rajasthan Tourism page describes Rajsamand as "The marble Land of Rajasthan" and says it is well known for marble production and is the largest marble-producing district in the country. Rajsamand stands apart because the largest number of marble production units operate there. Jalore, Jodhpur, and Nagaur are genuine mineral locations, but they do not answer this specific production-leadership question.
Why the other options are wrong
- (B) Jalore is linked mainly with granite stone, so it does not match the production-based identification of the leading marble district.
- (C) Jodhpur is associated here with badami marble and maximum limestone production, not with being the leading marble-producing district.
- (D) Nagaur contains Makrana, noted for white marble, but the highest overall marble output is assigned to Rajsamand.
Concept
This tests Rajasthan's economic geography of minerals: not just where a mineral occurs, but which district leads in production. RAS repeats such questions because Rajasthan's building-stone minerals are a core part of state geography and resource-based industry.
