Jhamarkotra , the largest rock phosphate deposit of India, is located in which district?
- A.Jaisalmer
- B.Udaipur
- C.Banswara
- D.Pali
Correct answer
Explanation
The correct answer is B, Udaipur. Jhamarkotra, a short distance from Udaipur city, is the largest rock phosphate deposit in the country and the main domestic source of raw material for phosphatic fertiliser, which India otherwise imports in large quantity. The same district also holds the Zawar lead and zinc mines and the green marble of Rishabhdeo.
Option A is wrong because Jaisalmer district is known for the Sanu limestone, for natural gas and for smaller rock phosphate occurrences such as Birmania. Option C is wrong because Banswara district is the manganese district of the state. Option D is wrong because Pali district is associated with the Jawai dam and with textile and stone work rather than phosphate. A second line of questions asks what Jhamarkotra ore is used for, and the answer is phosphatic fertiliser, which links this mine to the fertiliser plants of the state.
