It is the product of a poorly sorted accumulation of shell fragments and mud. Source for information on biomicrite: A Dictionary of Earth Sciences dictionary.Apr 1, 2023 · Biomicrite with lithoclastes (MFJ): It is made up of metric benches of limestone with Mudstone to Wackestone Textured. It is very rich in lithoclasts ( Fig. 3 : R), the biophase is not abundant and very little diversified, with in particular Crinoids and benthic Foraminifera (Alveolina, Lenticulina ( Fig. 3 : S)). 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.It represents fossiliferous biomicrite in Falk classification.
