RAS question
Zawar mines in Rajasthan are famous for which mineral?
Correct answer: (A) Lead-Zinc.
Zawar mines near Udaipur in Rajasthan are famous for lead-zinc deposits.
Explanation
Zawar is identified with lead-zinc, not with iron ore, copper or mica. The mines are near Udaipur, are one of the world's oldest zinc mining sites, and are operated by Hindustan Zinc Limited. The Rajasthan Department of Mines and Geology also lists Zawar (Udaipur) under the State's important lead-zinc-silver deposits, and its table names the Zawar group of mines with Pb and Zn grades. Lead-Zinc is the precise association for Zawar. Rajasthan is India's largest lead-zinc producer, so Zawar is a standard location-mineral association for Rajasthan Geography.
Why the other options are wrong
- (B) Iron ore is not the primary mineral associated with Zawar; the official minerals page places Zawar under lead, zinc and silver, while iron ore is listed separately.
- (C) Copper is not the Zawar association; copper mining is linked with Khetri in Jhunjhunu instead.
- (D) Mica does not fit Zawar because mica is placed mainly in Bhilwara and Ajmer districts, whereas Zawar is tied to lead-zinc near Udaipur.
Concept
Rajasthan Geography requires matching major mineral deposits with their locations. Mineral-location pairs recur in RAS because they are quick, high-yield factual checks in state geography.
