उत्तर
The distribution of coal in India is more abundant on the eastern side of the country. In India, coal occurs in rock series of two main geological ages—Gondwana and tertiary. While Gondwana coal is about 200 million years old, tertiary deposits are approximately 55 million years old. The major resources of Gondwana (metallurgical) coal are located in the Damodar valley (West Bengal, Jharkhand), Jharia, Raniganj and Bokaro. The Godavari, Mahandi, Son and Wardha valleys also contain coal deposits. Tertiary coals occur in the northeastern states of Meghalaya, Assam, Arunachal Pradesh and Nagaland.
