Carbonaceous sediments and rocks. Carbonaceous sediments and rocks, primarily coal, have been classified in two ways: by rank (content of carbon and caloric value) and by petrographic characteristics. In order of increasing rank, the classes of coal are (1) lignite; (2) subbituminous coal; (3) bituminous coal; and (4) anthracite.silt and micrite.

The middle unit (209 m {690 ft} thick) is a light olive-gray to medium light gray, very thick-bedded to massive cherty limestone. It is primarily a silty and sandy pelsparite, pelmicrite, wackestone, and grainstone sequence which was deposited in restricted circulation in shelf, shelf lagoon with open circulation, and tidal flat environments. This unit interfingers southward with (2) less fossiliferous, color-mottled biomicrite. An oolite-pelletoid facies (3) composed of oosparite, oomicrite, pelsparite, and pelmicrite overlies the biomicrite and mottled biomicrite facies. An algal mound complex composed of phylloid algal biomicrite is present in the southern part of the outcrop belt.Micrite is lime mud, carbonate of mud grade. In the Folk classification micrite is a carbonate rock dominated by fine-grained calcite. Carbonate rocks that contain fine-grained calcite in addition to allochems are named intramicrite, oomicrite, biomicrite or pelmicrite under the Folk classification depending on the dominant allochem.Micrite is lime mud, carbonate of mud grade. Micrite as a component of carbonate rocks can occur as a matrix, as micrite envelopes around allochems or as peloids. The origin of micrites is still a problem in carbonate sedimentology due to the non-uniqueness of the processes generating it. [3] Micrite can be generated through multiple processes ...
