Limestone, or calcium carbonate, is the common rock found throughout the world. Oldest and perhaps slightly overlooked, limestone is very much part of our everyday life. It may be hidden with your walls, in the water you drink, the food you consume, or in the cosmetics.
What is Limestone? Limestone is a sedimentary rock composed primarily of calcite, a calcium carbonate mineral with a chemical composition of CaCO 3.It usually forms in clear, calm, warm, shallow marine waters. Limestone is usually a biological sedimentary rock, forming from the accumulation of shell, coral, algal, fecal, and other organic debris.
The Importance of Calcium Carbonate. Calcium carbonate (CaCO3) comprises more than 4% of the earth's crust and is found worldwide. Its most common natural forms are chalk, limestone, and marble (produced by the sedimentation of small fossilized shellfish, snails, and coral over millions of years).
