Limestone consists of 80 percent calcite and Dolomite with more than 50% calcium carbonate.Caves form in limestone (calcium carbonate), and occasionally in dolomite (calcium magnesium carbonate), when water containing dissolved carbon dioxide (carbonic acid) seeps into rock crevices and joints.
Calcium enters the soil in several ways. One way is by degrading minerals like calcite, limestone, and dolomite. These and other soil parent materials release calcium into the soil. Calcium is a base cation critical in cation exchange. Cation exchange capacity is the number of cations the soil could hold.High-calcium limestone contains a high concentration of calcium carbonate, while dolomitic limestone contains a significant amount of magnesium carbonate. The high-calcium and dolomitic...…
