Limestone ( calcium carbonate CaCO3) is a type of carbonate sedimentary rock which is the main source of the material lime. It is composed mostly of the minerals calcite and aragonite, which are different crystal forms of CaCO3. Limestone forms when these minerals precipitate out of water containing dissolved calcium.

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.里氏词典提供oolitic pelmicrite 的意思,oolitic pelmicrite的解释,oolitic pelmicrite的翻译,方便你的学习和生活.

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. Family I includes respectively intrasparite, oosparite, biosparite, and pelsparite; family II includes intramicrite and oomicrite (both rare), biomicrite, and pelmicrite.
