It may also contain other minerals such as dolomite (CaMg (CO3)2), clay minerals, and other impurities. The purity of limestone depends on the geological conditions under which it formed. Travertine limestone and calcareous tufa consist of calcium carbonate deposited from hard water. Stalactites and stalagmites in caves are formed in the same way. Limestone rock is often riddled with caves because water and carbon dioxide dissolve the limestone. Chalk is a soft, white limestone containing the shells of foraminifera.
