摘　　要：河南方城莫沟萤石矿地处豫南萤石矿矿集区,成矿条件优越。为研究该矿床地质特征及矿床成因,为本地区找矿提供可靠资料,通过对莫沟萤石矿地质特征及成矿背景的分析,认为本区含矿地层为栾川群煤窑沟组大理岩,矿体赋存于断裂构造内,严格受断裂构造控制,呈陡倾斜脉状。萤石类型为方解石—石英—金云母—萤石型,萤石的成矿年龄为141Ma,其成矿时代为早白垩世。初步认为研究区萤石矿成因为中低温热液充填型萤石矿床。Mogou Fluorite Mine in Fangcheng county, Henan province is located in the fluorite ore collection area of southern Henan, with superior mineralization conditions. In order to study the geological characteristics and causes of the deposit, and to provide reliable data for prospecting in the region, through the analysis of the geological characteristics and mineralization background of the Mogou fluorite mine, it is believed that the mineral-bearing strata in this area is marble of the Luanchuan fromation, and the ore body is stored in the fault structure, strictly controlled by the fault structure, and shows a steep inclined vein. The fluorite type is calcite-quartzgolden mica-fluorite type, and the mineralization age of fluorite is 141 Ma, and its mineralization age is early Cretaceous. It is believed that the genesis of fluorite ore in the study area is medium and low temperature hydrothermal filled fluorite deposits.
