Kendall, 2005 (after Folk 1959)The term “micrite” is a contraction of the words “microcrystalline calcite” and was introduced by Folk ( 1959, p. 8) as an aid in the classification of limestones. Initially, Folk applied the term to microcrystalline calcite ooze in the size range of 1–4 μm. Adding a prefix, he coined terms such as “biomicrite” to refer to ...

Majority of the carbonate grains, in the present case, are <0.004 mm in size. Some grains are rounded and have reached up to 0.01 mm. In his original classification Robert L. Folk defined three main components to limestones. These are allochems, comprising various grains and particles; micrite ( micr ocrystalline calc ite mud matrix); and sparite ( spar ry calc ite cement). The main allochems are bioclasts (‘bio-’, see below), pellets (‘pel-’), intraclasts (‘intra ...
