摘　　要：梭罗沟金矿区构造较为发育,从晚二叠世开始至晚三叠世末为扬子被动大陆边缘的构造活动带和洋内裂谷带,经历了板块碰撞拼贴及长期陆内改造作用,印支期末至喜山期为松潘-甘孜造山带与扬子板块的碰撞接合带与陆内造山带,发生了复杂的构造-沉积-火山作用事件,是三江地区岩浆活动和沉积作用最活跃的场所之一,也是成矿作用的重要地区之一。梭罗沟金矿构造形迹以断裂为主,形成近东西向、近南北向、北西向、北东向四组断裂构成的构造格架,尤以与金矿关系最为紧密的近东西向主干断裂F1最为活跃,其具有多期活动性及继承性复合特征。通过对梭罗沟金矿区断裂特征及其与成矿关系的研究,以期对矿区下一步深部开采及增储勘查工作提供有利的地质依据。The structure of Suoluogou gold deposit is relatively developed.From the late Permian to the end of the Late Triassic,the Yangtze passive continental margin tectonic active belt and intracontinental rift belt experienced plate collision collage and long-term intracontinental transformation.From the end of the Indosinian to the Himalaya period,the Songpan-Ganzi orogenic belt and the Yangtze plate collided and intercontinental orogenic belt,where complex tectonic-sedimentation-volcanic events occurred.It is one of the most active places of magmatic activity and sedimentation,and one of the important areas of mineralization in Sanjiang Area.The main structural trace of the Suoluogou gold deposit is faults,which form a tectonic framework composed of four groups of faults near east-west,near south-north,north-west and North-East.Particularly,the near east-west main fault F1,which is most closely related to the gold deposit,is the most active and has multi-phase activity and inheritance compound characteristics.The studying on the fault characteristics and its relationship with mineralization in the Suoluogou gold deposit provides favorable geological basis for further deep mining and reserve-increasing exploration.
