A possible geochemical mechanism of the conjugation of the carbon and calcium cycles in the ocean

The geochemical balance of carbon in the ocean is considered for the conditions of constant carbonate alkalinity. It is shown that the intrabasin processes result in the annual transformation of 487 million t of organic carbon into calcium-magnesium carbonates, which is accompanied by the extraction of 1628 million t of calcium from silicates. It is concluded that the hypothesis of the reverse weathering based upon the notion of the inversion of the mineral formation processes in the ocean against the overland weathering processes requires a substantial correction.
