Limestone is a sedimentary rock composed largely of the minerals calcite and aragonite, which are different crystal forms of calcium carbonate (CaCO 3).
Limestone represents roughly 10 percent of all sedimentary rock in the world. Limestone generally forms on the shallow floors of tropical waters when seashells, sand and other sediment are compressed together. Limestone can be called a young marble. Crystals of cement grow around the young marble from grains that are made from animal seashells. A famous architectural marvel created with limestone is the Great Pyramid of Giza.
