【摘要】 超基性岩蛇纹石化为化能自养微生物群落提供了所需要的能量和初始物质,是生命起源最重要的变质水化反应。研究显示,蛇纹石化橄榄岩中有两种来源的有机化合物,一是蛇纹石化期间,在还原和高浓度H₂条件下,通过费-托合成反应产生的非生物成因有机化合物;另一是海洋有机质热降解和/或包含微生物活动残留的有机化合物。但要确定后者与生命演化的相关性和同生性,尚缺乏必要和充分的证据。更多还原

【Abstract】 The serpentinization of ultramafic rocks could provide necessary energy and raw materials to support chemosynthetic microbial communities. It is the most crucial metamorphic hydration reaction in the formation of life. Organic compounds in serpentinized peridotite could be sourced either from abiogenic organic compounds generated through the FTT type reaction under condition of reduction and high hydrogen concentration during serpentinization of peridotite,or from biogenic organic compounds originated from Thermal degradation of oceanic organic matter and/or from residual organic matter of microbial activity. However,there is still lack of sufficient evidences to confirm the relationship between the biogenic organic compounds in serpentinized peridotite and the evolution of life.更多还原
