REE GEOCHEMICAL FEATURES OF WOXI Au-Sb-W DEPOSIT IN WESTERN HUNAN

沃溪金锑钨矿床稀土元素的研究表明：在成矿作用过程中，近矿脉围岩及矿层较远矿脉围岩发生了重稀土的迁出流失，稀土元素从赋矿围岩向含矿断裂带内定向迁移，断裂构造岩稀土元素的总含量与其构造破碎程度及所受的构造应力应变强度成正相关。

This paper studies the REE geochemical feature of the Woxi deposit in Western Hunan. The results show, during mineralization, HREE in the adjoining veins‘ wall-rocks and ore-layers was migrated or lost as compared with HREE in the faraway veins' rocks, REE migrated directionally from the adjoining ore-bearing wall-rocks into ore -forming fault zones, the total REE contents of the structural rocks are positively related to the level of the rocks fragmenting and strength of their structural stress deformation, ore-forming material came mostly from the ore-bearing strata rocks.
