摘　　要：竹园北金矿处于秦岭造山带北带临潭—宕昌断裂带上,金矿体主要受NW向断裂构造控制,围岩蚀变以硅化、黄铁矿化、褐铁矿化、毒砂化、绢云母化为特征,载金矿物为褐铁矿、黄铁矿、黄铜矿、毒砂、黄钾铁钒。断裂构造及侵入岩是基本控矿因素,近NW向构造蚀变带和化探异常发育部位是找矿有利地段。Located in Lintan-Dangchang fault zone of Qinling orogenic belt, Zhuyuanbei gold deposit is mainly controlled by NW trending faults, the wall rock alteration have silicification, pyritization, limonitization,arsenopyrite, sericitization, gold is hosted in minerals, limonite, pyrite, arsenopyrite, chalcopyrite, yellow ferric potassium alum of. Faults and intrusions are the basic ore controlling factors, nearly NW tectonic alteration zone and geochemical anomaly development area is the favorable area for prospecting.
