The vast majority of carbonate sediments are . In warm, shallow, clear marine waters, organisms extract calcium and carbonate ions from seawater to build their protective shells and skeletons. When these organisms die, their remains accumulate on the seafloor, becoming buried and eventually lithified into limestone. As the Manchester University Carbonates project explains, “carbonate rocks are biogeochemical precipitates, made up primarily of calcium carbonate, which forms the shells of numerous marine organisms, such as corals, molluscs and plankton.” Cenozoic carbonates)
