这些微生物通过生命代谢过程,使渗漏系统中的CH4被氧化转变为CO2,同时孔隙水中的SO4~(2-)还原成H2S,与Ca和Fe离子结合沉淀冷泉碳酸盐岩。
These bacteria collaborate to oxidize venting methane to CO2 and reduce seawater sulfate to H2S by their metabolism in the seeping system . The abundance of COi and HaS , causes the seep carbonate to be deposited .

渗漏晚期,天然气渗漏速度很慢(q<0.55kg/m2a),在海底附近没有水合物沉淀,主要以冷泉碳酸盐岩发育为主,水合物产于海底之下一定深度的沉积层中。
The venting rates are slow ( gas flux q < 0.55 kg / m ~ - a ) in the later stage , hydrate crystallization will not reach the sea floor , seep carbonate will be occurred on the seafloor .
