WitrynaWhat is fine grained limestone? Fine grained limestone (micritic) (ID:053) Fossils are mainly fragments of thin pelecypod pellet shells. Pelecypod fragments are made up of calcite crystals and measure a few millimetres. The size of the calcite matrix varies between 1 and 5 microms because the micrite is recrystallized at some points.
