Many fissures were formed in peninsular India during the Carboniferous period. Basin-like troughs were formed due to the submergence of the land through these cracks. In these pits, coal was formed due to vegetation suppression and the action of heat and pressure on it. Presently coal is present in the river basins of India like Damodar, Son, Mahanadi, Godavari and Wardha etc.
Bituminous coal is found in India and is considered second-grade coal. The first-grade coal is called anthracite. Most of the coal of India is found only in the rocks of the Gondwana order.
