摘　　要：文中论述了谢家沟金矿床矿区地质构造演化特征;谢家沟金矿床主要矿脉体特征及矿化类型;厘定了谢家沟金矿床的成因类型为同韧性剪切带蚀变岩型金矿;确定了张家庵—谢家沟—铁夼韧脆性剪切带控矿构造系统的存在,并对其地质特征、控矿模式及成矿远景进行了论述。Jiaodong gold deposit cluster is the most important gold mineralization area in north China. The research works on Linglong goht-bearing quartz-vein type deposit are the base of gold deposit research of China; the discovery of Jiaojia cracking-altered rock gold deposit is a great breakthrough in the area of gold deposit research and prospecting. Xiejiagou gold deposit is an alteration-rock type deposit, which is controlled by ductile shear belt, and its discovery initiates a new way to prospect gold deposit in Jiaodong gold deposit cluster. The paper reveals the geological tectonic evolution features of Xiejiagou gold deposit. The characteristics of goht veins, its mineralization type and origin are discussed in detail, it is believed that Xiejiagou gold deposit is an alteration-rock type deposit which is controlled by ductile shear belt. The paper makes sure the existence of ZhangjiaanXiejiagou-Tiekuang ductile shear belt ore-controlling system. The geologic features, the ore-controlling model and the mineralizing perspective of the system are also discussed.
