Limestone composition

Micrite is a limestone constituent formed of calcareous particles ranging in diameter up to four μm formed by the recrystallization of lime mud. The term was coined in 1959 by Robert Folk for his carbonate rock classification system. …

Limestone areas are predominantly affected by chemical weathering when rainwater, which contains a weak carbonic acid, reacts with limestone. This causes the limestone to dissolve. Carbon dioxide from the respiration of animals (and ourselves) is one cause of increased carbon dioxide in the atmosphere. Burning fossil fuels also contributes to this.Apr 23, 2023 · Limestone is primarily composed of calcium carbonate (CaCO3) in the form of the mineral calcite. It may also contain other minerals such as dolomite (CaMg (CO3)2), clay minerals, and other impurities.
