How Limestone is Formed

While you might think limestone is limestone, there are many different types of carbonate rock. Chalk is a fine-grained, porous limestone while travertine is a freshwater, more sedimentary limestone that has thin layers. Marble is also a carbonate rock that has been squeezed down and formed into a different material with heat and pressure.

Limestone: The Calcium Carbonate Chemical Sedimentary Rock

"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.
