和平县金山堂萤石矿位于湘东—赣南—粤东萤石矿矿集区的中部,通过对矿区开展地质勘查工作,在深部控制了萤石矿体的规模、产状、形态和空间位置.萤石矿体呈脉状产于F1断裂构造破碎带中,矿体形态、产状受断裂构造所控制,产状与其基本一致.矿脉为复脉型,局部有分支复合现象.矿石类型主要为石英—萤石型、萤石型、萤石—石英型,多呈致密块状构造、角砾状、网脉状构造及少量梳状构造.根据矿体产出特点,结合区域类似矿床的成矿地质特征,认为矿床成因类型为热液充填型脉状萤石矿床.%The Jinshantang fluorite ore is located in the central area of the fluorite ore mine of east Hunan-south Jiangxi-east Guangdong. By geological exploration in the mining area, deep engineering have controlled the scale, orientation, shape and spatial location of the ore bodies. Fluorite deposit is formed in Fl fault fracture zone. The shape and orientation of the ore bodies is under the control of the fault fracture structure. So its occurrence is in basic agreement with the fault fracture structure. The veined ore bodies are complex and have branch composite phenomenon in some parts. The ore types are mainly quartz-fluorite type, fluorite type, fluorite-quartz type, mostly of a dense block structure, brecciated structure, nets pulse shape structure and a few comb structure. According to the ore body output features, and combined with the geological characteristics of the metallogenic area of similar deposits, we think that the ore desposit is the vein-type fluorite deposit of hydrothermal filling origin.
