mostly of calcium carbonate (CaCO. 3), but to geologists, limestone is only one of several types of "carbonate rocks." These rocks are composed of more than 50% carbonate minerals, generally the minerals calcite (pure CaCO. 3) or dolomite (calcium-magnesium carbonate, CaMg[CO. 3] 2) or both. Most carbonate rocks were depos-ited from seawater.

Limestone is a relatively common sedimentary rock formed from remains marine organisms such as coral or other invertebrates, and composed largely of calcium carbonate and other carbonates. Limestone can be defined as having 90% or more of calcite (CaCO3), the other 10% usually being a mixture of dolomite (CaCO3.MgCO3) and various impurities,
