| Grade of Limestone | Prominent Region/District |
|---|---|
| A. Steel Grade (SMS) | i. Sanu (Jaisalmer) |
| B. Chemical Grade | ii. Gotan (Nagaur) |
| C. Cement Grade | iii. Nimbahera (Chittorgarh) |
| D. Yellow Limestone (Decorative) | iv. Jaisalmer City region |
Explanation
Sanu in Jaisalmer is the primary source for high-grade steel melting shop (SMS) limestone. Gotan in Nagaur is famous for high-purity chemical-grade limestone used in various industrial processes. Nimbahera in Chittorgarh is a major center for cement-grade limestone. The Jaisalmer city region is known for its beautiful yellow decorative limestone, frequently used in local and historical architecture.
Q333. What is the most appropriate central focus of the Rajasthan Mineral Policy concerning the socioeconomic conditions of mine workers?
Explanation
A central focus of the Rajasthan Mineral Policy is the welfare of mine workers, particularly ensuring their occupational health and safety. The policy emphasizes mitigating the risks of respiratory diseases like silicosis, which is common in stone carving and mining. It aims to improve working conditions and provide medical support, recognizing the socioeconomic importance of the mining labor force.
Q334. The Degana mines in the Nagaur district are geographically associated with which specific hill feature known for tungsten deposits?
Explanation
The tungsten deposits in the Degana area of Nagaur district are geographically located on Rewat Hill.
Q335. Read the given statements and select the correct answer from the options provided:
Statement I: The Khetri Copper Complex was established by Hindustan Copper Limited (HCL), a public sector enterprise.
Statement II: The complex relies solely on imported copper concentrates and does not process ore from the local Singhana mines.
Statement I: The Khetri Copper Complex was established by Hindustan Copper Limited (HCL), a public sector enterprise.
Statement II: The complex relies solely on imported copper concentrates and does not process ore from the local Singhana mines.
Explanation
The Khetri Copper Complex was established by the public sector undertaking Hindustan Copper Limited to process local copper ore. While it may occasionally use imported concentrates to supplement production, it was fundamentally designed to process ore from the nearby Khetri and Singhana mines. The assertion that it does not process any local ore is incorrect and factually baseless.
Q336. Identify the correctly matched pair regarding the specific color of Marble and its famous source district in Rajasthan:
Explanation
Bhainslana in Jaipur district is the most famous source for high-quality black marble in Rajasthan. Pink marble is primarily associated with regions like Jalore and Banswara, while Makrana is world-renowned for white marble. Green marble is famously found in Rikhabdev in the Udaipur district. These distinct colors are the result of specific mineral impurities present during the rock’s formation.
Q337. In the context of Rajasthan’s mineral wealth, why is the state often categorized as having a monopolistic advantage in certain sectors?
Explanation
Rajasthan is described as having a monopolistic advantage because it is the sole or dominant producer of certain minerals in India. It accounts for almost 100% of the national production of lead, zinc, and wollastonite. This unique geological endowment makes the state a critical supplier for these minerals, which are essential for various industrial applications ranging from metallurgy to ceramics.
Q338. The rock phosphate deposits in the Jaisalmer district are geographically heavily concentrated in which of the following prominent areas?
Explanation
In Jaisalmer district, rock phosphate deposits are found in the Birmania and Fatehgarh areas. These are typically sedimentary deposits. While Jhamarkotra and Maton are the most famous rock phosphate sites in the state, they are located in the Udaipur district. Zawar is associated with lead and zinc, and Morija-Banol is known for iron ore, distinguishing these geographical regions clearly.
Q339. Which of the following statements regarding Granite in Rajasthan is incorrect?
Explanation
Granite is an intrusive igneous rock, not a sedimentary one. It forms from the slow cooling of magma beneath the earth’s surface and is found across several districts in the Aravalli range and surrounding regions. While it is processed in arid districts like Jalore, its geological origin is igneous. The other statements about its strength, processing industries, and colors are accurate.
Q340. Match the items in List I with those in List II and select the correct answer using the options provided:
| Iron Ore Mining Area | District |
|---|---|
| A. Morija-Banol | i. Udaipur |
| B. Nathra-Ki-Pal | ii. Dausa |
| C. Neemla-Raisela | iii. Jaipur |
| D. Chomu-Samod | iv. Jaipur (Rural/Region) |
Explanation
Morija-Banol is the most significant iron ore deposit in the Jaipur district. Nathra-Ki-Pal is a well-known iron ore site located in Udaipur. Neemla-Raisela is a prominent mining area in the Dausa district. Chomu-Samod is another region near Jaipur where iron ore deposits are found. These sites together contribute to the state’s total production of hematite-grade iron ore deposits.Answer key for these questions

Key facts from Rajasthan Geography
- The RPSC syllabus lists Rajasthan’s location, extent and physiography, rivers and lakes, climate, vegetation, biodiversity, soils, agriculture, livestock, irrigation, population, urbanisation and tribes.
- Many questions ask for a number or a name: the area of the State, a district’s density, the length of a canal, the home district of a mine.
- Rajasthan is the biggest State of India by area, and several chapters test the contrast between the arid west and the humid south-east.
- Minerals, irrigation and wildlife are the chapters with the most name-based questions, so keep a list of districts and projects.
- Population questions use Census 2011 figures.
