摘　　要：谢家沟金矿是近年来在胶东半岛新发现的一个大型韧性剪切带型金矿。通过分析该金矿的控矿构造特征,对剪切变形与金矿化关系进行了探讨,认为金矿体大多数产在主剪切带中,其容矿构造往往为韧性剪切带或脆性构造破碎带内的片理化带。研究表明,该金矿的形成与早期的韧性剪切活动以及后期的脆性改造都有成因联系。Xiejiagou Gold deposit, a large ductile shear Zone hosted gold deposit, was discovered newly in recent years in Jiaodong peninsula. The characteristics of ore - controlling structure in the gold deposit were analyzed, and the relations between the shear distortion and gold mineralization were discussed. It was considered that gold orebodies generally occur in main shear zones, the ore -bearing structures are usually ductile shear zones or schistosity zones in brittle fracture zones. The formation of the gold deposit is related to earlier ductile shearing activity and later brittle reformation.
