Coal, Rocks and Minerals, Kentucky Geological SurveyCoal is formed from peat, which is an accumulation of decayed vegetation usually associated with swamps. The process of the transformation from peat to coal is called coalification. In the stages of coalification, peat is altered to lignite, lignite is altered to sub-bituminous coal, sub-bituminous coal is altered to bituminous.coal facts, information, pictures | Encyclopedia articles about coalBituminous: Soft coal; a form of coal with less heat content and pure carbon content than anthracite, but more than lignite. .

In vitrinite these compounds are connected by cross-linking oxygen, sulfur, and molecules such as methylene. During coalification, volatile phases rich in hydrogen and oxygen (e.g., water, carbon dioxide, and methane) are produced and escape from the mass; hence, the coal becomes progressively richer in carbon.
