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.

Abstract . The Permian Phosphoria Formation is a reservoir for oil and gas in the western United States, as well as a major source of phosphate.Significant volumes of rock are in the process of being converted to biomicrite and pelmicrite by massive biological erosion and cementation by Mg-calcite micritic cement. Many rocks also display textures similar to some attributed to recrystallization or replacement in ancient limestones.The shallow water association is a gray-green silty shale, a breccia, a clastic limestone, an encrusted grain (oncolite) microfacies, and a massive pelmicrite.

The rock is characterized by well-stratified grain fabric.pelmicrite. [ ′pel·mə‚krīt] (geology) A limestone containing less than 25% each of intraclasts and ooliths, having a volume ratio of pellets to fossils greater than 3 to 1, and with the micrite matrix more abundant than the sparry-calcite cement.

Thus a pelmicrite is composed of pellets with a micrite matrix, and an oosparite consists of ooliths with a sparry calcite cement. Carbonate rocks undergo mineralogical changes (diagenesis) during burial and lithification. For example, aragonite is frequently converted to calcite.
