Theories of carbonate deposition

Theories of carbonate deposition explain how carbonates, like limestone, form in aquatic environments. One major theory suggests that these deposits occur when marine organisms, such as corals and shellfish, produce calcium carbonate for their structures. Another theory highlights the role of chemical processes, where dissolved carbon dioxide in water forms calcium carbonate under certain conditions, often in warmer, shallower seas. These processes contribute to the creation of diverse geological formations over time, shaping landscapes and influencing ecosystems. Both biological activity and chemical reactions are essential in understanding how these rich deposits accumulate.
