摘　　要：文章以河南南阳地区某萤石矿为研究对象,系统分析了矿区成矿地质条件,总结了萤石矿的找矿标志。根据勘查工作区矿物组合、矿石结构构造、围岩蚀变及控矿条件特征,发现矿体产状与断裂构造基本一致,勘查区的萤石矿化严格受断裂构造控制,在F_(1)、F_(2)、F_(6)和F_(7)断裂构造带中共圈出四个萤石矿体。矿体内部结构比较简单,矿石类型为萤石—石英型,萤石品位较稳定。对勘查区内的萤石矿潜在矿物资源量进行了初步估算,估算潜在资源量(CaF_(2)矿物)8.3万吨,矿石总量22.9万吨,CaF_(2)矿物量平均品位为36.24%,平均厚度为1.58 m。希望该研究可以为该地区后续的矿产资源开采提供一定参考。To take a fluorite deposit in Nanyang,Henan Province as the research object,this article systematically analyzes the geological and metallogenic condition of the mining area,and summarizes the prospecting indicator for the fluorite deposit.Based on the mineral composition,ore texture and structure,rock alteration,and ore-controlling condition in the exploration work area,it is found that the occurrence of the ore body is basically consistent with the fault structure.The fluorite mineralization in the exploration area is strictly controlled by the fault structure,and four fluorite ore bodies are circled out in F_(1),F_(2),F_(6),and F_(7)fault zones.The internal structure of the ore body is relatively simple,and the ore type is fluorite quartz type.The fluorite grade is relatively stable.A preliminary estimation of the potential mineral resources of fluorite ore body is made for the exploration area,with an estimated potential resources of 83000 tons(CaF_(2)mineral)and a total ore amount of 229000 tons.The average grade of CaF_(2)mineral content is 36.24%,and the average thickness is 1.58 m.It is hoped that this study can provide some reference for the subsequent development of mineral resources in the area.
