Anthracite also called hard coal the most highly metamorphosed form of coal It contains more fixed carbon 86 percent or greater on a dry ashfree basis than any other form of coal and the least amount of volatile matter 14 percent or less on a dry ashfree basis and it has calorific values near 35 megajoules per kilogram
Coal is a hard rock which can be burned as a solid fossil is mostly carbon but also contains hydrogen sulphur oxygen and is a sedimentary rock formed from peat by the pressure of rocks laid down later on top Peat and therefore coal is formed from the remains of plants which lived millions of years ago in tropical wetlands such as those of the late Carboniferous
