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.Sample 5 is a pelmicrite (Folk 1959) or a mudstone.

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.

(D) Abraded gastropod shell fragment in aggregate-bearing pelsparite. Gastropod shells are preserved as moulds filled by blocky calcite cement.For example, a limestone comprising pellets in a mud matrix is called a ‘pelmicrite’, and a limestone comprising shell fragments with a sparry calcite cement is a *‘biosparite’. It is possible to combine the prefixes of several allochems where appropriate, e.g. ‘oobiosparite’.

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.

A third assemblage consisting of an encrusted grain microfacies, a pelmicrite, a delicately laminated shaly micrite, and a thinly bedded black shale, is found in the thickest ...Micrite is a limestone constituent formed of calcareous particles ranging in diameter up to four μm formed by the recrystallization of lime mud. [1] [2] The term was coined in 1959 by Robert Folk for his carbonate rock classification system. [2] Micrite is derived from MICRocrystalline calcITE.
