摘 要:山西萤石矿产地分布少,地质工作程度较低;浑源董庄萤石矿床现为山西仅有的具有可开采利用价值的萤石矿产地。董庄萤石矿体主要产于石英斑岩和黑云斜长片麻岩硅化断裂破碎带中,并严格受NW-SE走向张-张扭性断裂(带)控制;矿石类型主要为石英-萤石型,主矿体有用组分CaF2含量在53.20%~59.56%;矿床成因类型属于硅酸盐中典型的中-低温热液充填型脉状矿床。The distribution of fluorite minerals in Shanxi is small and the degree of geological work is low;the fluorite deposit in Dongzhuang,Hunyuan is the only one with Exploitable value in Shanxi.Dongzhuang fluorite ore body is mainly produced in silicified fracture zone of quartz porphyry and biotite plagioclase gneiss,and strictly controlled by NW-SE strike Tensional-torsional fault(zone);the ore type is mainly quartz-fluorite type,with CaF2 content of 53.20%~59.56%as the useful component of the main ore body;the genetic type of the deposit belongs to typical medium-low temperature hydrothermal solution in silicate.Filling vein deposit.
