Q351. Read the given statements and select the correct answer from the options provided: Given below are two statements, one labelled as Assertion (A) and the other labelled as Reason (R): Assertion (A): Beneficiation plants for Rock Phosphate have been established at Jhamarkotra in Udaipur. Reason (R): The locally extracted rock phosphate ore contains high levels of silica and dolomite impurities that must be removed to upgrade it for fertilizer grade.
Explanation
Beneficiation plants are essential at Jhamarkotra because the raw rock phosphate ore often contains high levels of silica and dolomite. These impurities must be removed to produce a high-grade concentrate suitable for fertilizer manufacturing. By processing the low-grade ore locally, the industry ensures the efficient utilization of the resource and improves the economic viability of the operations in Udaipur.

Q352. Which of the following statements regarding silver mining in Rajasthan is incorrect?
Explanation
Rajasthan does not have any independent, large-scale pure silver mines. All significant silver production in the state is derived as a by-product during the smelting of lead and zinc ores from mines like Zawar and Rajpura-Dariba. While the state is the top silver producer in India, this production is entirely linked to the processing of polymetallic base metal ores.

Q353. Match the items in List I with those in List II and select the correct answer using the options provided:
Famous Mining Area
Corresponding Mineral
A. Jhamarkotra
i. Marble
B. Makrana
ii. Copper
C. Rampura-Agucha
iii. Rock Phosphate
D. Khetri
iv. Zinc
Explanation
Jhamarkotra is the leading site for rock phosphate. Makrana is synonymous with high-quality white marble. Rampura-Agucha is a world-class source for zinc and lead. Khetri is the heart of copper mining in Rajasthan. These associations are fundamental to understanding the state’s economic geography, as each location is a primary national center for its respective mineral, contributing to growth.

Q354. The sandstone deposits of Rajasthan, particularly from districts like Jodhpur, Bundi, and Dholpur, are structurally classified as which type of rock?
Explanation
Sandstone is a classic example of a sedimentary rock, formed from the accumulation and cementation of sand-sized mineral grains or rock fragments over millions of years. In Rajasthan, extensive sandstone formations in districts like Jodhpur, Bundi, and Dholpur provide a variety of building stones. These rocks are characterized by their layered structure and are widely used in construction due to durability.

Q355. Consider the following statements about Gypsum deposits in Rajasthan: I. Rajasthan produces over 80% of India’s total gypsum output. II. The Got-Manglod area in Nagaur is a prominent site for gypsum mining. III. Gypsum is heavily utilized in the manufacturing of Plaster of Paris and Portland cement. Which of the above statement(s) is/are correct?
Explanation
Rajasthan dominates India’s gypsum production, contributing over 80% of the total output. The Got-Manglod area in Nagaur is a well-known mining site for this mineral. Gypsum’s industrial utility is vast, serving as a primary component in manufacturing Plaster of Paris and as a retarder in cement production. Its agricultural use for soil reclamation further enhances its economic and strategic significance.

Q356. Identify the odd one out concerning the typical spatial distribution of these minerals in Rajasthan:
Explanation
Copper, iron ore, and lead-zinc deposits in Rajasthan are primarily found in the Aravalli range and its associated hard-rock geological formations. These are typically metallic minerals formed through igneous or metamorphic processes. In contrast, the gypsum deposits in the Bikaner-Nagaur basin are marine evaporite deposits found in western sedimentary basins, making their geological setting and spatial distribution entirely distinct.

Q357. Consider the following statements about the physical and chemical properties of Mica found in Bhilwara and Ajmer: I. It has excellent basal cleavage, allowing it to be split into very thin, flexible sheets. II. It is a highly efficient conductor of electricity. III. It can withstand very high temperatures without significantly degrading. IV. It is completely soluble in ordinary water. Which of the above statement(s) is/are correct?
Explanation
Mica is renowned for its perfect basal cleavage, which allows it to be split into extremely thin, flexible sheets. It also has high thermal stability, enabling it to withstand high temperatures. However, it is an excellent electrical insulator, not a conductor, which is why it is used in electronics. Additionally, mica is chemically inert and insoluble in water, making other statements incorrect.

Q358. The strategic utility of Tungsten extracted from the Degana mines stems directly from which physical effect when alloyed with steel?
Explanation
The strategic value of tungsten lies in its incredible hardness and high melting point. When alloyed with steel, it creates "high-speed steel" that retains its hardness and structural integrity even at very high temperatures. This property is crucial for manufacturing cutting tools, drill bits, and specialized military equipment that must endure extreme heat and friction without failure, justifying the mineral’s strategic importance.

Q359. Consider the following statements regarding the characteristics of Iron Ore in Rajasthan: I. The deposits are heavily concentrated and are the largest single unbroken iron ore belt in India. II. Hematite is the most commonly extracted form of iron ore in the Jaipur-Dausa regions. III. The scattered and limited nature of deposits restricts the establishment of massive integrated steel plants in the state. IV. Micaceous hematite is found in some southern districts. V. The overall quality of most deposits is of medium to low grade. Which of the above statement(s) is/are incorrect?
Explanation
Iron ore deposits in Rajasthan are actually scattered and relatively small compared to the massive, unbroken belts found in states like Odisha. This fragmented nature is a primary reason why the state lacks large integrated steel plants. While hematite is the main ore and the quality is generally medium-grade, the claim that Rajasthan has the largest unbroken iron ore belt is false.

Q360. Which of the following districts is NOT generally associated with significant commercial production of Granite in Rajasthan?
Explanation
Jalore, Barmer, and Sirohi are all major centers for commercial granite production in Rajasthan, with Jalore being the most famous. Jaisalmer, however, is better known for its vast deposits of yellow limestone, sandstone, and gypsum. While some granite may exist in the region, Jaisalmer is not categorized as a significant commercial hub for granite production compared to the mentioned districts.

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.
