Pelmicrite: This microfacie has less than 10% grains; the dominating non-skeletal grain is peloid. The dominating matrices are the micritic muds which are essentially greyish in colour. At the upper left hand corner is the dark patches of mud which is suggesting a re-deposition from another environment.Mar 1, 1975 · The evaporite minerals in the Main Limestone rocks seem to be overwhelmingly early diagenetic in origin in the light of the following observations: (1) calcite or dolomite pseudomorphs after gypsum crystals associated with a fine pelmicrite matrix; (2)associa- tion of such pseudomorphs with oolitic pelsparite; and (3) evaporite solution breccia ...

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.Using the pelmicrite facies that formed in deeper wetlands, we interpret a lower temperature zone (35–40°C) to reflect warm season water temperatures.
