While Gondwana coal is about 200 million years old, tertiary deposits are approximately 55 million years old. Classification of Coal . The coal of India may be classified under two categories: (I) Gondwana coal, and (II) Tertiary coal. Gondwana coal. Gondwana coal belongs to the carboniferous period (570 million years to 245 million years back).

Gondwana coal accounts for 98 % of India's total coal reserves and 99 percent of its coal production. Gondwana coal is moisture-free and high in phosphorus and sulfur. When compared to Carboniferous coal, Gondwana coal has a lower carbon content (that is 350 million years old which is almost absent in India because of its much younger age).
