Consider the following statements:1. Natural gas occurs in the Gondwana beds.2. Mica occurs in abundance in Kodarma.3. Dharwars are famous for petroleum.Which of the statements given above is/are correct ?
✓ Correct answer: b) 2 only
ExplanationStatement 1 is incorrect: The Gondwana beds are pri- marily famous for containing coal reserves, with nearly 98% of India’s coal reserves found in them.They are not significant for natural gas reserves.Natural gas in India is more common- ly associated with other formations such as sedimentary basins such as the Cambay Basin or the Krishna-Godavari Basin.Statement 2 is correct: Kodarma in Jharkhand is a well-known region for mica production, which has been an important min- eral in India’s mineral resources.Mica is found abundantly here and Kodarma is often referred to as the “mica capital” of India.Statement 3 is incorrect: The Dharwar system of rocks is not known for petroleum production.The Dharwar rocks are partic- ularly valuable for metallic minerals like high-grade iron ore, manganese, and copper.Petroleum is not found in the Dhar- war rock system but in other formations like the Cambay Basin or the Rajasthan Basin.101
