Calcium carbonate precipitated; CaCO3; Molar mass 100.0869 g/mol Also known as calcite; aragonite; chalk; Lime (material); Limestone; marble; oyster; pearl It is a chemical compound used in agricultural lime and as an antacid. It is derived from a number of different rocks including  limestone,  chalk,  marble and travertine but these are just part of the calcium cycle. MARTYN F. CHILLMAID/SCIENCE PHOTO LIBRARY
