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?

1. Statement 1 is incorrect. Gondwana beds in India are primarily known for their vast coal deposits. Major conventional natural gas reserves in India are mainly found in younger Tertiary rock formations in offshore basins (like Mumbai High, KG basin) and onshore fields (Assam, Gujarat). While Coal Bed Methane (CBM) can be associated with Gondwana coal seams, these beds are not the primary source of conventional natural gas occurrences. 2. Statement 2 is correct. Kodarma, located in Jharkhand, has historically been one of the world's largest producers of high-quality sheet mica and is often referred to as the 'Mica Capital of India'. Mica occurs in abundance in this region. 3. Statement 3 is incorrect. The Dharwar system rocks are ancient, highly metamorphosed geological formations known primarily for being rich sources of metallic minerals like iron ore, manganese, gold, and copper. They are not associated with petroleum reserves, which are typically found in younger, unmetamorphosed sedimentary basins.
