中文摘要:
      六安金矿位于广西大瑶山金成矿带中部,矿区出露地层主要为寒武系,主要赋矿层位为寒武系小内冲组和黄洞口组浅变质细碎屑沉积岩。矿化带受北东向和北西西向断裂控制,并产于次级断层及层间破碎带中。该矿区的矿石属于贫金属硫化物的破碎带蚀变岩型金矿石。矿石中金主要以裸露与半裸露自然金的状态存在。近矿围岩蚀变有硅化、黄铁矿化、绢云母化、绿泥石化和褐铁矿化等,沿断层破碎带及其旁侧发育。六安金矿控矿因素可归纳为构造因素、地层因素、岩浆岩因素和区域变质作用因素。大瑶山地区金矿化类型丰富多样,可归为一个成矿系列。
英文摘要:
      Liuan gold deposit is located in the middle area of Dayaoshan gold metallogenic belt, Guangxi. The emergence stratum mainly is Cambrian, and the epimetamorphic microclastic sedimentary rock of Xiaoneichong group and Huangdongkou group are the main hosting ledges. The mineralized zone are controlled by the NE trend faults and the NWW trend faults, and the ore bodies occurs mainly in the secondary faults and the interlayer fracture zones. The ore type belongs to altered rock type ore in fault crushed zone, and metal sulfide is poor. The wall rock alteration includes silication, pyritization, sericitization, chloritization, limonitization, which distributed along the fault fracture zones and side. The ore-controlling factors of Liuan gold deposit can be concluded as structural factor,formation factor, magmatic factor and regional metamorphism factor. The gold mineralization types in Dayaoshan area are various and abundant and can be classified as a metallogenic series.
