These fabrics are: (1) pseudofibrous calcites that are believed to have replaced acicular/fibrous cements with original aragonite and/or Mg-calcite mineralogy, (2) pelmicsparite-pelmicrite areas, (3) stromatolite-like crusts, and (4) early micritic cements.Interpretation.-We interpret the mottled micrite facies as deposition in a similar palustrine environment to that of the pebbly pelmicrite facies, although the mottled micrite likely experienced ...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.

Micrite is lime mud, carbonate of mud grade. In the Folk classification micrite is a carbonate rock dominated by fine-grained calcite. Carbonate rocks that contain fine-grained calcite in addition to allochems are named intramicrite, oomicrite, biomicrite or pelmicrite under the Folk classification depending on the dominant allochem.
