How coal is formed. Coal is formed when dead plant matter submerged in swamp environments is subjected to the geological forces of heat and pressure over hundreds of millions of years. Over time, the plant matter transforms from moist, low-carbon peat, to coal, an energy- and carbon-dense black or brownish-black sedimentary rock.
The major coalfields in India are located in the eastern and central regions of the country, and the coal found in India is primarily bituminous and sub-bituminous in nature.
