REE是了解和研究地球表生过程的一个重要手段。通过REE的化学性质、物源和在表生水中的迁移和分配,综述了REE在表生过程水中的独特行为和再分配的全过程,同时利用表生水作用的代表产物——页岩,讨论了REE在水与古沉积物中的作用和指示意义。由于REE测试方法中存在的问题,指出了过去研究中可能错误的结论和当前重新评估REE在水和岩石圈演化中分配及其地质意义的重要性。

Rare Earth Elements (REEs) play an important role on understanding and studying hypergene processes.As of the chemical characteristics,input resources,migration and fractionation of REE in hypergene water,the complete process of REE′s activation and re fractionation is summarized,and the significance of REE in natural water and paleo sediments is also discussed by shale relative to deeper sea sediments.Considering the mistake found in the analytical means,it is necessary to recorrect the past wrong conclusions and to re estimate the geological significance of REE in water and evolution of lithosphere as well as other sediments.
