The degree of change undergone by a coal as it matures from peat to anthracite is known as coalification. Coalification has an important bearing on coal's physical and chemical properties and is referred to as the 'rank' of the coal. Ranking is determined by the degree of transformation of the original plant material to carbon.

Coal - Simple English Wikipedia, the free encyclopedia

Coal is a hard rock which can be burned as a solid fossil fuel.It is mostly carbon but also contains hydrogen, sulphur, oxygen and nitrogen.It is a sedimentary rock formed from peat, by the pressure of rocks laid down later on top.The harder forms of coal, such as anthracite, are metamorphic rocks, which means they were changed by very high temperature and pressure.

Coal Formation [Athro, Limited: Geology: Gubik Trip]

Lignite typicaly transforms to bituminous coal as it is compressed further and heated to between 100 and 200°C. This drives much of the water and other volitiles from the coal. Longer exposure to elevated temperature will further drive volatiles from the coal, and drive chemical reactions that produce anthracite.
