摘要
汞铅锌矿是湖南凤凰地区的优势矿种。介绍了该区汞铅锌矿的地质特征及类型,结合实际地质资料,综合分析了该区构造控矿因素,初步提出了该区汞铅锌矿的构造控矿规律:区内汞铅锌矿床成因类型主要有层控叠加(沉积改造)型矿床和断层破碎带低温热液充填型脉状矿床;导矿构造为NNE向和NE向区域性大断裂——保靖—铜仁断裂;控矿构造为NNE向和NE向背斜核部及两翼,以及背斜与向斜转折部位;容矿构造为NW向小断裂、容矿层中节理裂隙、层间裂隙及破碎带。
Mercury-lead-zinc deposit is the dominant mineral in Fenghuang area of Hunan Province. Combined with the actual geological data,this paper introduced the basic geological characteristics and types of mercury-lead-zinc deposit. In addition,the tectonic control factors of mineralization were analyzed,and structural orecontrolling regularity was initially proposed. Mineralization types of mercury-lead-zinc deposit in the study area are stratabound superimposed( sedimentary reformation) deposit and mesothermal-epithermal filling of fault fracture zone vein deposit. The structure as the passageway for ore fluids of mercury-lead-zinc deposit is the NNE and NE regional faults( Baojing-Tongren fracture),and the controlled ore structure is the NNE and NE anticlinal core,two wings and the turning parts of anticline and syncline. Besides,the ore-hosting structure is NW small faults,let seam joints,interlayer fracture and fracture zone.
