How Does Organic Limestone Form?
It can be formed with the help of living organisms and by evaporation. Ocean-dwelling organisms such as oysters, clams, mussels and coral use calcium carbonate (CaCO3) found in seawater to create their shells and bones. … The water pressure compacts the sediment, creating limestone.
How is limestone formed and where is it found?
Most fresh water and sea water contain dissolved calcium carbonate. All limestones are formed when the calcium carbonate crystallizes out of solution or from the skeletons of small sea urchins and coral. … Such evaporation takes place in the hot lagoons of many coral reefs, and in most shallow tropical seas.
