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. Laminated, thin-bedded pelmicrite The bed shown below appears on a fresh-cut surface to be a very fine-grained calcilutite, but displays complex textural properties as well as a coarser-grained lithology. The rollover image highlights the development of what can be called a turbidite. Average warm season water temperatures of 41.1 ± 3.6°C and 37.8 ± 2.5°C are preserved by the palustrine pelmicrite (∼113–112 Ma) and lacustrine micrite (∼112–103 Ma), respectively.
