Limestone is a sedimentary rock composed primarily of calcite, a calcium carbonate mineral with a chemical composition of CaCO 3. It usually forms in clear, calm, warm, shallow marine waters. Limestone is usually a biological sedimentary rock, forming from the accumulation of shell, coral, algal, fecal, and other organic debris.


2.5 Most of the calcite precipitated by marine organisms contains a certain percentage of magnesium. Such calcite is called magnesian calcite; it's subdivided into low-magnesium calcite and high-magnesium calcite at 4% MgCO3 content. Generally the more advanced the organism, the less magnesium in the calcite.In the case of red algae, an important sediment producer, the
