湖南川口白水矿区钨矿成矿机制研究

Study on the metallogenic mechanism of tungsten deposits in Baishui ore district,Chuankou,Hunan Province

白水钨矿是川口钨矿田新近发现的一重要钨矿区。文章通过对该矿区成矿地质特征的综合研究,分析了矿化富集规律和控矿条件,对成矿机制进行了探讨。研究认为白水钨矿受高涧群架枧田组板岩及中侏罗世道士仙单元中-细粒白云母花岗岩控制明显,是在深部高温幔汁或岩浆沿断裂构造减压带向上侵入后,所产生的构造空间内富集成矿。

The white water tungsten deposit is an important tungsten deposit area recently discovered in the kawaguchi tungsten field.Based on the comprehensive study of the ore-forming geological characteristics,the paper analyzes the mineralization enrichment rules and ore-controlling conditions,and probes into the ore-forming mechanism.It is concluded that the control of the SLATE of ganjiantian formation of gaojian group and the fine-grained Muscovite granite of daoxian element in the middle Jurassic is obvious,and the mineral enrichment in the structural space is generated after the deep hightemperature mantle or magma intruding upward along the pressure relief zone of fault structure.
