英文摘要	Previous studies have estimated that mantle serpentinization reactions generate H-2 at a rate of 10(10)-10(12) mol/yr along the global mid-ocean ridge (MOR) system. Here we present results of 3-D geodynamic simulations that predict rates of additional mantle serpentinization and H-2 production at oceanic transform faults (OTF). We find that the extent and rate of mantle serpentinization increases with OTF length and is maximum at intermediate slip rates of 5 to 10 cm/yr. The additional global OTF-related production of H-2 is found to be between 6.1 and 10.7 x 10(11) mol/yr, which is comparable to the predicted background MOR rate of 4.1-15.0 x 10(11) mol H-2/yr. This points to oceanic transform faults as potential sites of intense fluid-rock interaction, where chemosynthetic life could be sustained by serpentinization reactions.
