抄録

Global geochemical cycle has been described with boxes which indicate carbon reservoirs and fluxes between the boxes. Carbonate rock is one of the most important reservoirs because about 75% of carbon on the surface of the Earth is fixed in it. It is necessary to formulate processes related to carbonate precipitation and dissolution to reconstruct a dynamical system of an ancient climate. Carbon cycle models in the different three time scales (carbon productions in the Recent coral reef; carbonate deposition in the Quaternary; carbonate deposition in the Phanerozoic) were examined. Photosynthesis and calcification of communities are the primary processes in the Recent coral reefs, while the dissolution of the carbonate and weathering of silicate by CO₂ control the cycle in the geologic time.
