浙江青田县半寮萤石矿床地质特征及成因探讨

Geological characteristics and genesis discussion of Banliao fluorite deposit,Qingtian county in Zhejiang Province

文章对该区的萤石矿矿床成因进行了探讨,认为该区属于次火山低温热液充填脉型矿床。火山构造洼地周围的环状的张性断层和放射状的压性断层,为矿液运移提供了良好的通道。而后期的压扭性断裂为矿床的形成提供了有利的空间。

The genesis of fluorite deposits in this area is discussed in this paper.They are considered to be be-longed to the low temperature hydrothermal fluid filling vein type deposit.The cyclic tension and radial pres-sure faults of the volcanic structures provide the good channel for the transport of the ore fluid.The pres-sure-shear faults of late period provided the favorable space for the formation of ore deposits.
