Degana , the tungsten mining centre of Rajasthan, is in which district?
- A.Nagaur
- B.Bikaner
- C.Tonk
- D.Bundi
Correct answer
Explanation
The correct answer is A, Nagaur. Tungsten, in the form of the ore wolframite, is mined at the Rewat hill near Degana in Nagaur district, which has long been the main tungsten occurrence of the country. Nagaur district is a favourite of examiners because three different answers live in it: Makrana marble, Degana tungsten and the potash bearing Nagaur Ganganagar basin, besides gypsum at Gotan and limestone.
Option B is wrong because Bikaner district is the gypsum and lignite district, with Jamsar and Gurha. Option C is wrong because Tonk is known for garnet and for the Bisalpur dam. Option D is wrong because Bundi lies in the Chambal belt and is associated with limestone and sandstone. Examiners also ask for the name of the ore, which is wolframite, and for the use of tungsten, which is in filaments, cutting tools and hard alloys.
