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。 The Zhuyuan North Gold Mine is on the Lintan-Dangchang Fault Belt in the north of the Qinling orogenic belt. The gold ore body is mainly controlled by the NW-trending fault structure. Surrounding rock alteration is dominated by silicification, pyrite mineralization, limonite mineralization, arsenopyrite It is characterized by sericification and micritization. The gold-bearing minerals are limonite, pyrite, chalcopyrite, arsenopyrite and jarosite. The fault structure and intrusive rock are the basic ore-controlling factors. The tectonic alteration zone near NW and the abnormal geochemical exploration site are the favorable prospecting areas.
