Deposition of limestone
Most limestone is formed from the deposition of the hard remains of marine life, but can also form from the direct precipitation of calcium carbonate out of warm water. The calcium carbonate, usually in the form of calcite, is then buried, compacted, and eventually cemented together to form limestone.
