摘　　要：综述了表生地质体的Ce异常及其影响因素。指出除了氧化还原条件等因素之外,微生物和有机质也是引起表生地质体Ce异常的重要因素。Ce异常在研究全球变化、古环境演化、流体来源、环境污染和地下核废料演变过程等方面的示踪作用是重要的研究动向。This paper summarizes Ce anomalies in supergene geological bodies and its effecting factors. Besides redox condition, microorganisms and organisms are also considered as the main factors effecting on the Ce anomalies in supergene geological bodies. Potential applications of Ce anomalies in tracing global changes, paleoenvironmental evolutions, fluid origins, environmental pollutions and behaviours of fission reactor waste in underground medium are considered as the important studying trends in the field.

关 键 词：稀土元素 Ce异常 微生物 有机质
