摘　　要：冷泉是指以甲烷、硫化氢及其他碳氢化合物为主要成分的渗漏流体穿过海水-沉积物界面,到达海水甚至大气圈的现象。冷泉碳酸盐岩是冷泉微生物活动的直接产物,是冷泉流体及沉积环境信息的忠实记录者。主要回顾了冷泉自生碳酸盐岩各地球化学指标在冷泉系统微生物活动中的变化机制,这为还原古海洋氧化还原环境提供一个新的视角。Cold seeps represent the phenomenon where seepage fluids,primarily composed of methane,hydrogen sulfide,and other hydrocarbons,traverse the interface between seawater and sediments,reaching into the oceans and even the atmosphere.Cold seep carbonates stand as direct products of microbial activities within cold seep environments,faithfully recording the information embedded within the seep fluids and sedimentary settings.This review delves into the mechanisms of how various geochemical markers within cold seep authigenic carbonates undergo changes due to microbial activities within the cold seep systems,offering a novel perspective on reconstructing ancient marine redox environments.
