摘　　要：排山楼金矿床位于华北陆块北缘阜新地区金多金属成矿区,该矿床赋存于太古宙建平群深成变质岩中,受东西向韧性剪切构造控制。矿化蚀变由中心向外依次为黄铁矿-绢云母化-硅化蚀变带、钾长石化蚀变带、碳酸盐化蚀变带和绿泥石化蚀变带。矿床成因类型属于韧性剪切型金矿。The Paishanlou gold deposit is situated at the margin of the North China craton occurs in metallogenic zoning of Fuxin area gold and multi-metal deposits. The ore body forms are strictly controlled by EW trending ductile shear zone and hosted in mylonite of Archeozoic Jianping Group. Alteration can be divided into four altered zones from inside to outside,according to the strength of the alteration：pyritization-sericitization- silicification,K-feldspar,carbonation and chloritization. Genetic type of ore deposit belongs to ductile shear zone gold deposit.
