The calcium carbonate is a sedimentary rock which is mainly composed of calcite mineral (calcium carbonate: CaCo). The calcium carbonate is often composed of various quantities of silica mineral in the form of chert or flint, as well as various amounts of clay, silt, and sand, as intercalations, nodules or interbedded layers. The main source of calcite in limestone is usually marine organisms, so that their shells deposit on the ocean floor. As well, the secondary calcite may be deposited by supersaturated meteoric waters (ground waters that cause the deposition in caves), and consequently cave deposited layers such as stalagmite and stalactite are formed.

The Calcium carbonate is especially used in architecture, and many historical masterpieces all around the world, especially in North America and Europe are made from this combination. Many buildings in Kingston, Ontario of Canada are made of calcium carbonate, so they are also called calcareous cities. Among the most important artworks of the world, the Abraham Lincoln Statue in Washington, the Parthenon Building in Athens, the Church ceiling of Kraków in Poland, and the Great Lion Statue of London’s Trafalgar Square are made of the calcium carbonate. Another feature of the calcium carbonate is that it could be easily crushed into smaller pieces. Meanwhile, its durability is long-lasting and could be well exposed on the surface. The application of the calcium carbonate in buildings was common in the early

ساختار اندام دام دارای ذخایری از منیزیم است. که بخش عمده ای از آن در است.خوان های مهره ها و دنده نگهداری می شود. و هنگامی که در دام ها کمبود منیزیم اتفاق می افتد،به منظور جبران آن از ذخیره منیزیم است.خوان‌هایشان است.فاده می‌کنند. که این حالت در دام های جوان اتفاق می افتد  در حالی که دام های بالغ به علت کمبود منیزیم در اثر بروز Tetany تلف می شوند.
