中文摘要:
      湘西金矿沃溪大断层是一条张剪性正断层,具不顺层性质,有蚀变、矿化和成矿活动,以及多阶段活动特征。断层倾角大于层状矿脉系,估计在深部会切错矿体,因此在断层深部上盘应存在着找寻工业矿体的远景。
英文摘要:
      In Xiangxi gold mine,Woxi fault was generally believed as a bedding and reversed fault and is of overthrust and nappe characters.Accoring to relation among the fault and stratum and ore bed,the features of tectonites,and interrelation of the fault and ore body,it is a tensile shear normal fault.It is characterized by high metallogenic elements and high heavy minerals and altered fractural rock type Au ore body(Yuershan).Isotopic age determination shows multistage and multiphase activities. The dip angle of Woxi tensile shear normal fault is steeper than bedded ore vein systems.It may cut the ore body in deep position so that there is the foreground of looking for ore body in hanging wall at depth.In addition,there are the foregrounds to look for ore deposits in Yuershan and Hongyanxi districts,etc.,in western sector of Woxi fault,and Dongzichong Xiaotaoyuan zone of northern part as well.
