摘　　要：松溪寺坑矿区萤石矿矿体整体受断裂构造控制,均呈脉状或长透镜状贮存于硅化破碎带中。萤石矿微量元素、Sr同位素、H-O同位素与流体包裹体测温显示成矿流体来源于同期岩浆作用,具有中低温、低盐度特征,且明显受到大气降水的混合,分析认为寺坑萤石矿的成因类型属于低温热液充填型。The fluorite ore body of Sikeng mining area in Songxi county is controlled by fault structure,and is stored in the silicate crushing zone in a pulse body or a long lens.Fluorite ore trace elements,Sr isotopope,H-O isotopope and fluid wrap shows that the metallogenic fluid comes from synchronous magma,which is characterized by low temperature and low salinity,and is obviously mixed by atmospheric precipitation.The analysis shows that the origin type of Sikeng fluorite mine belongs to the low-temperature hydrothermal filling type.
