Continental-pelagic carbonate partitioning and the global carbonate-silicate cycle.

  title={Continental-pelagic carbonate partitioning and the global carbonate-silicate cycle.},
  author={Ken Caldeira},
A carbonate-silicate geochemical cycle model is developed and used to explore dynamic and climatic consequences of constraints on shallow-water carbonate burial and possible carbon loss to the mantle associated with sea-floor subduction. The model partitions carbonate deposition between shallow-water and deep-water environments and includes carbon fluxes between the mantle and lithosphere. When total lithospheric carbonate mass is constant, there are two stable steady states, one in which the… CONTINUE READING
