Most carbonate sediments are produced in what geologists call the "carbonate factory" The Origin of Carbonate Sedimentary Rocks: A Comprehensive
In certain environments, carbonate crystals can precipitate directly from the water column without biological intervention. This occurs when water becomes supersaturated with respect to calcium carbonate, often due to changes in temperature, pressure, or CO₂ content. The most famous example is the formation of : small, sand-sized spherical grains that form by the layered accretion of calcite or aragonite around a tiny nucleus in high-energy, shallow-water settings like the Bahamas. While the origin of fine-grained carbonate mud (micrite) is a topic of ongoing scientific debate, leading hypotheses point to a combination of direct water-column precipitation and the physical and biological breakdown of algal skeletal components. The most famous example is the formation of
Structureless, fecal or microbial aggregates of fine-grained carbonate mud.
