摘　　要：工作区处在桐柏-大别褶皱带上,基本构造格架表现为高压超高压变质带被低缓伸展滑脱片麻理带所改造的片麻岩穹窿带,后期岩浆活动及混合岩化作用强烈,地质构造比较复杂。萤石矿化体主要赋存于东西向断裂中,围岩主要为片岩、片麻岩、花岗岩及大理岩。矿床成因以低温热液充填型为主。共圈定萤石矿脉6条;初步估算两矿脉（333）＋（334）？CaF2资源量46.36万吨。The workspace in tongbai- dabie fold belt, the basic tectonic framework show the high ultrahigh pressure metamorphic zone are relatively low stretch slippage transformation by MIT take pills Ma Yan Qiong with it, in the late magmatic activity and migmatization, strong geological structure is complicated. Fluorite mineralization mainly occurs in the east-west fracture, the surrounding rock are mainly schist and gneiss, granite and marble. Genesis is given priority to with low temperature hydrothermal filling type. A total of delineating fluorite veins 6; Preliminary estimates two veins（333） ＋（334）？ Ca F2 463600 tons of resources.
