Correct Option
The correct option is 1 and 3 only.
Explanation
The North-Western Mineral Belt of India primarily extends along the Aravallis in Rajasthan and parts of Gujarat. This region is geologically distinct from the peninsular plateau and is characterized by non-ferrous minerals, building stones, and significant energy resources.
Statement-wise Analysis
- Statement 1 is Correct: The region is well-known for its deposits of building stones, including sandstone, granite, and marble. It also holds extensive reserves of gypsum and fuller’s earth. Furthermore, the dolomite and limestone found here serve as critical raw materials for the cement industry.
- Statement 2 is Incorrect: The region is a major producer of salt, not devoid of it. The low rainfall and high evaporation rates in the arid zones of Rajasthan (e.g., Sambhar Lake) and the coastline of Gujarat facilitate significant salt production.
- Statement 3 is Correct: The North-Western region possesses substantial energy resources. Gujarat and Rajasthan are known for rich reserves of petroleum and natural gas, found in sedimentary basins such as the Barmer and Cambay basins.
Key Takeaway
The North-Western Mineral Belt is distinguished by its richness in non-ferrous metals (copper, zinc), industrial minerals (gypsum, salt), building stones, and hydrocarbon energy resources, contrasting with the ferrous-rich North-Eastern Plateau.
