How is Gondwana coalfield different from tertiary coalfield

Tertiary coalfields are found in Assam, Arunachal Pradesh, Meghalaya, Nagaland, Kashmir and in the coastal areas of Tamil Nadu, Gujarat and inland basin of Rajasthan. This coal is free from moisture and contains sulphur and phosphorus in small variable quantities. This coal has a higher moisture content and more sulphur, with less calorific value.

The Road to Gondwana: In Search of the Lost Supercontinent

The mountains, deserts, and other landscapes that existed on Gondwana can still be found on the continents that it makes up, and the coal deposits formed from the ancient Glossopteris continue to be a major source of energy globally. The break-up of Gondwana also had a profound effect on the global distribution of species.

What are the types of coal? | U.S. Geological Survey

There are four major types (or "ranks") of coal. Rank refers to steps in a slow, natural process called "coalification," during which buried plant matter changes into an ever denser, drier, more carbon-rich, and harder material. The four ranks are:Anthracite: The highest rank of coal. It is a hard, brittle, and black lustrous coal, often referred to as hard coal, …
