江西大吉山花岗岩风化壳稀土矿床稀土元素地球化学

Geochemical Study of REE from Granite Weathering Crusts in Dajishan of Jiangxi Province

本文系统采集分析了江西大吉山花岗岩体及其风化壳样品，通过研究其不同类型花岗岩风化壳的矿物组成、稀土元素组成和稀土元素的分配，得出了风化壳中稀土元素的分布特征和规律，讨论了风化作用过程中稀土元素的迁移机制。

By systematic sampling on the different granites and their weathering crusts and analysis on the samples,the paper studies the compositions of minerals of the different granite weathering crusts and their REE.The mechanism of REE migration during weathring has been discussed.
