Origins of calcium carbonates
Calcium carbonate is one of the most abundant minerals found on the earth. Almost all calcium carbonates originated from the remains of organic skeletal material produced in a marine environment. A much smaller quantity originated from reaction of calcium salts with carbon dioxide. There were several different sub-environments within this marine environment. These were reef formations (such as coral), shallow water organisms (such as oysters and mussels found in lagoons), and the continental shelf where skeletal sediments formed the main sea bed building mechanism. Over a period of millennia, the environment of the deposit changed. ...
