Carbon mantle fluxes

Coupled Sulfur and Carbon Cycles and the Net Mantle Flux... [Pg.62]

Sano, Y. and Williams, S.N. (1996) Fluxes of mantle and subducted carbon along convergent plate boundaries. Geophy.s. Res. Udt., 23, 2749-2752. [Pg.428]

Hydrothermal reactions between seawater and young oceanic crust have been proposed as an influence on atmospheric O2 (Walker, 1986 Carpenter and Lohmann, 1999 Hansen and Wallmann, 2002). While specific periods of oceanic anoxia may be associated with accelerated hydrothermal release of mantle sulfide (i.e., the Mid-Cretaceous, see Sinninghe-Damste and Koster, 1998), long-term sulfur and carbon isotope mass balance precludes substantial inputs of mantle sulfur to the Earth s surface of a different net oxidation state and mass flux than what is subducted at convergent margins (Petsch, 1999 Holland, 2002). [Pg.4412]
