Limestone is a sedimentary rock composed largely of the mineral calcite (calcium carbonate, CaCO 3 ). It makes up about ten percent of the total volume of all sedimentary rocks. A unique feature of this rock is that its main constituent, calcite, is produced chiefly by shell-producing and coral-building living organisms.
