摘　　要：现代海洋环境中超基性岩广泛发生蛇纹岩化,导致富氢气(H2)和无机成因甲烷(CH4)的流体渗漏活动和化能自养生物群的发育,该过程常伴有自生碳酸盐岩和水镁石沉积的形成。本文综述了现代不同海洋环境(洋中脊、弧前泥火山与海沟等)与海底蛇纹岩化有关的碳酸盐岩的地质地球化学及标志性生物特征,介绍了自生碳酸盐岩及其中生物标志物研究无机成因CH4记录的研究现状以及古代蛇纹岩化相关的碳酸盐岩的地质地球化学特征,指出了该领域存在的关键问题以及研究重点。Serpentinization of ultramafic rocks,occurred widely in the modern ocean,results in the venting of hydrogen and abiogenic methane-rich fluids,thedevelopment of chemosynthetic communities,and the formation of authigenic carbonates and brucite.This paper has comprehensively reviewed the geological,geochemical and biomarker characteristics of authigenic carbonates associated with the serpentinization of ultramafic rocks in different modern oceanic settings（mid-ocean ridges,forearc of subduction zones and trench slope）,introduced the research status of record of abiogenic methane in the authigenic carbonates and their biomarkers,and the geological and geochemical characteristics of the carbonates associated with the acient serpentinization,and finally pointed out some critical problems and key issues of the research in this discipline.
