介绍了用含有溶解二氧化碳的海水对大洋岩心进行水解的过程。结果表明,此水解过程可导致生成非生物成因的甲烷和氢。在含铁超基性岩的蛇纹岩化作用过程中,通过二价铁氧化为三价铁、二氧化碳还原,可以生成大量的甲烷。同时,海水经二价铁的分解,释放出氢。大洋岩石中甲烷的生成速度可达9×106t/a,氢的生成速度达9.7×106t/a.其中,大量的甲烷和氢因细菌的作用而发生酸化,除一部分气体散布到大气中之外,其余以热液或天然气水合物形式在大洋中储(沉)积下来。
The process of hydrolyzing oceanic cores with seawater containing dissolved carbon dioxide is described. The results show that this hydrolysis process can lead to the formation of non-biological methane and hydrogen. In the process of serpentinization of iron-bearing ultramafic rocks, a large amount of methane can be generated through the oxidation of ferrous iron to ferric iron and carbon dioxide. At the same time, seawater is decomposed by ferrous iron to release hydrogen. The generation rate of methane in oceanic rocks is up to 9 × 106t / a and the hydrogen generation rate is 9.7 × 106t / a, in which a large amount of methane and hydrogen are acidified by the action of bacteria, except some of the gas is dispersed outside the atmosphere , And the rest is stored (sunk) in the ocean as hydrothermal or gas hydrate.
