Carbonate has played an important role on global carbon cycle. The fossil carbonate component of deep-sea sediments provides much of our knowledge of its fluctuation as well as paleoclimatic change. The compiled data on the distribution, preservation, and accumulation of carbonate on the seafloor indicate that depth of sedimentary lysocline has fluctuated markedly in conjunction with late Quaternary climate cycles and that carbonate sedimentation is much affected by the fluctuation of the abyssal carbonate ion concentration. Also it is suggested that the fluctuations of the dissolution are largely controlled by changes in the global mass balance of carbonate and ocean circulation, which have a close relationship with climatic conditions.
