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.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. ….
