Coal - Wikipedia

Coal is a combustible black or brownish-black sedimentary rock, formed as rock strata called coal seams.Coal is mostly carbon with variable amounts of other elements; chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of years.

What is coal? | World Coal Association

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 coals physical and stone 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.

Vitrinite - Wikipedia

Vitrinite is a type of maceral, where "macerals" are organic components of coal analogous to the "minerals" of rocks. Vitrinite has a shiny appearance resembling glass (vitreous). It is derived from the cell-wall material or woody tissue of the plants from which coal was formed. Chemically, it is composed of polymers, cellulose and lignin.
