Limestone formation
Limestone is a carbonate sedimentary rock that consists predominantly of calcite [CaCO 3 ]. Limestones are the commonest rocks that contain non-silicate minerals as primary components and, even if they represent only a fraction of all sedimentary rocks (about 20 – 25%), their study is fundamental to understand past environments, climate, and ...

The rock forms from accumulated organic debris from shells, corals, algae, and fecal matter. Some reserves are also formed by chemical sedimentary processes such as calcium carbonate precipitation from lake or ocean water. Biological limestone usually forms in clear, warm, and peaceful shallow marine waters.
