Plants and animals absorb calcium carbonate in water, where it usually exists dissolved in the form of calcium hydrogen carbonate Ca(HCO 3) 2, and use it to build up their skeletons and shells. After their death, mussels, coccoliths, algae and corals form sedimentary deposits on sea beds and the rockforming process is set in motion.

Dec 10, 2008· Calcium is an alkaline material widely distributed in the earth. It is the fifth most abundant element (by mass), usually found in sedimentary rocks in the mineral forms of calcite, dolomite and gypsum. [1] We often see it as marble or limestone, which is formed by calcium carbonate rock dissolved in water containing carbon dioxide.
