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 [2013]

Consider the following statements:

Gondwana beds are known for coal deposits and Natural gas is typically found in marine sedimentary rocks.

Around 98% of India’s coal reserves and 99% of coal production are from Gondwana fields.
Because of its much younger age, the carbon content in Gondwana coal (250 million years old) is less than that of carboniferous coal (350 million years old—almost absent in India).
Gondwana coal is free from moisture, but it contains sulphur and phosphorus.
Coking, as well as non-coking coal and bituminous coal, are obtained from Gondwana coal fields. EG-MR – 20
Anthracite is generally not found in the Gondwana coal fields.
The Damuda series (i.e. Lower Gondwana) hosts the most productive coalfields (80% of India’s total coal production.

Kodarma, in Jharkhand, has rich mica deposits. It’s a major source of mica, particularly muscovite.
Major mica-bearing pegmatites occur in states including Andhra Pradesh, Bihar, Jharkhand, Maharashtra, Odisha, Rajasthan, and Telangana.

The Dharwar craton in Karnataka, India, is known for its mineral resources like iron ore and gold, not petroleum.
