福建武平悦洋银多金属矿床特征及成因探讨

On the Characteristics and Genesis of the Yueyang Silver Polymetallic Deposit in Wuping County,Fujian Province

武平悦洋银多金属矿床受基底与火山岩系不整合面附近发育的一组铲式断裂裂隙带控制,以独特的石英+冰长石+银(金)和绢云母+银铜蚀变矿化组合区别于紫金山矿区石英+明矾石+铜(金)组合,与紫金山地区五子骑龙铜矿床、罗卜岭斑岩型铜矿床共同构成与中酸性次火山斑岩有关的浅成低温斑岩铜金银矿成矿(亚)系列。

The Yueyang silver polymetallic deposit in Wuping County is controlled by a group of shovel-shaped faults and fractured zones distributed over the unconformity surface between the basement and volcanic series. It has an unique alteration and mineralization assemblage of quartz＋ kalifeldspath＋ silver and sericite ＋ silver （gold） and copper, which is quite different from the quartz ＋ alunite ＋ copper assemblage in the Zijinshan mining. All the deposit, the Wuziqilong copper deposit and the Luopuling porphyry copper deposit in the Zijinshan area are made up of a metallogenic series of epizonal low-temperature porphyry copper-gold-silver deposits which are relative to the intermediate and acidic subvolcanic porphyry.
