  • Origins and Composition of Coal
DEF

A coal whose attritus is composed mainly of transparent humic degradation material.

OBS

Depending on the origin, coals have been grouped in to (a) sapropelic coal, and (b) humic coals ... Unlike sapropelic coals the humic coals are banded in character and the constituent bands are distinct in their physical appearance. Humic coals have a series of rank starting from wood-peat-lignite-bituminous coal to anthracite. In humic coals, the remains of wood and bark predominate. Over time, geological processes apply pressure to peat, which is transformed successively into the following ranks: lignite, ... subituminous coal, ... bituminous coal [and] anthracite.
