Q1. Which of the following statements is not correct about Gondwana coal?
A The Gondwana coal belongs mainly to the Permian period.
B It is found in the Damodar, Mahanadi, Godavari and Narmada valleys.
C It is mainly peat and lignite type of coal. Correct
D Raniganj, Jharia, Tata Pani and Himgiri are some of the important coal mines of Gondwana formation.
Explanation
Gondwana coal in India is mainly associated with Permian-age Gondwana formations, and it is generally high-grade bituminous coal, not mainly peat or lignite. Peat is the earliest, poorly carbonised stage, and lignite is a low-grade brown coal, so that description does not fit Gondwana coalfields. The Damodar, Mahanadi, Godavari and Narmada valley belts are associated with Gondwana deposits. Raniganj, Jharia, Tata Pani and Himgiri are also recognised coalfield or mine areas linked with the Gondwana formation.
