韧性剪切变形过程中稀土元素的变异——对“稀土元素在剪切带中的含量变异及其变异机制”一文的讨论

The Variation of REE in the Process of Ductile Shearing: A Discussion on the Paper of “Variation of REE Content in Shear Zone and Its Mechanism”

本文通过对周建波等人 1998年发表在本刊上的有关韧性剪切带稀土元素稳定性一文的讨论 ,结合国内外有关稀土元素在各地质环境中的活动性和韧性剪切带流体渗滤作用对体系中元素迁移影响的研究成果 ,探讨了韧性剪切变形过程中稀土元素的可变性质及其控制因素。

The paper gives detailed comment on the paper of “Variation of REE content in shear zone and its mechanism——Exemplified by the ductile shear zone on the northern margin of Jiaonan orogenic belt”, published in this magazine in 1998. Combined with the results of mobility of REE in various geological environments and the element migrations effected by fluid flowing in the ductile shear zones, the author expounds that fluid infiltration and rock volume loss are controlled factors of REE variation in the process of ductile shearing.
