The remains of ancient plants are transformed into solid combustible minerals through coal-forming, with an ash content generally less than 40%. The remains of higher plants are formed in swamps through peatification, forming a loose, water-rich organic deposit. The remains of aquatic lower plants and plankton are deposited in lakes, lagoons, bays and other environments, forming organic mud rich in water and asphalt through sapropelism. The original material for coal formation includes the process of accumulation and transformation of the remains of higher plants, lower plants and plankton into coal.

Definition and explanation
A kind of humic

saprophetic coal
a kind of coal with low coalification degree transformed from peat or sapropel through diagenesis. Its appearance is mostly brown, with dull luster, and contains high internal moisture and different amounts of humic acid. Bituminous coal; bitu-minite anthracite hard coal stone-like coal natural bonite; native mineral coke. The coal with a coalification degree lower than anthracite but higher than lignite is transformed from lignite through metamorphism. Its volatile matter yield range is wide. When coking alone, it ranges from no coking to strong coking. It produces smoke when burning. Bituminous coal is transformed from metamorphism into coal with a high coalification degree. It has low volatile matter, high density, high ignition temperature, no adhesiveness, and does not emit smoke when burned. It is a general term for bituminous coal and anthracite. It is mainly a solid combustible mineral with low calorific value and high coalification degree that is transformed from the remains of fungi and algae in shallow seas, lagoons, bays and other environments in the Early Paleozoic Era through sapropelization and coalification. Generally contains a large amount of minerals, and is named after its appearance of black rock.
