摘　　要：南台子金银矿床是由1∶50000水系沉积物测量异常发现的,地处华北地台北缘上黄旗构造岩浆隆起带上,该区内具备地层、构造、岩浆岩等优越成矿地质条件;侏罗系张家口组中酸性火山碎屑岩、火山熔岩,爆破角砾岩,NE向断裂、近EW向断裂,与成矿关系密切;爆破角砾岩蚀变发育,深部钻探工程验证发现2个金矿体。本文在梳理区域成矿背景和矿区地质特征的基础上,分析了矿区控矿因素和找矿潜力,提出了找矿方向。Nantaizi Au-Ag deposit is discovered by tracing anomaly delineated during river sediment survey at scale 1∶50000.It occurs in the Shanghuangqi structure-magma up heaval belt where metallogenic condition is superior,such as intermediate-acidic volcanic pyroclastic rock,lava and blasting breccia of Jurassic Zhangjiakou formation and NE fault and nearly EW fault which are closely related to formation of the deposit.The blasting breccia is developed with alteration and 2 Au ore bodies are hit by drilling to its depth.This paper comb the regional metallogenic background,geological characteristics and ore-control factors of the deposit and points out the prospecting potential and direction.
