From the geological perspective, limestone formation takes place in two different environments, sedimentation in marine waters and by water evaporation during cave formation. Marine Environment to Form Limestone Most limestones form in clear, shallow marine waters - an environment where organisms can form calcium carbonate shells."Limestone" means any rock formed 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.
