Carbonate rocks are made of particles composed >50% carbonate minerals embedded in a cement. Most carbonate rocks result from the accumulation of bioclasts created by calcareous organisms. Therefore carbonate rocks originate in area favoring biological activity i.e. in shallow and warm seas in areas with little to no siliciclastic input.

The carbonate–sili e geochemical cycle also known as the inorganic carbon cycle describes the long-term transformation of sili e rocks to carbonate rocks by weathering and sedimentation and the transformation of carbonate rocks back into sili e rocks by metamorphism and volcanism. Carbon dioxide is removed from the atmosphere during burial of weathered minerals and returned to the
