Coal Rank Classification | SpringerLink

The rank of a coal is characteristic of the stage reached by it in course of coalification. The development from peat through the stages of lignite, subbituminous, and bituminous coals to anthracite and meta-anthracite is termed coalification. Coalification or coal metamorphism is a function of heat and pressure acting over a period of time.
