福建宁德市蕉城区贵村银多金属异常区地球化学特征及其找矿远景分析

Geological Characteristics and Ore-finding Perspective of the Guicun Silver-polymetallic Anomalous Zone in Jiaocheng District,Fujian Province

蕉城区贵村银多金属异常产于侏罗系上统南园组第二段流纹质晶屑凝灰熔岩和燕山晚期第一阶段第三次侵入钾长花岗岩内外接触带上。与北东向、近南北向断裂带以及石英细脉带关系密切。区内银多金属异常范围较大,已见5条矿化蚀变脉和若干老洞,找矿远景良好。

Guicun silver-polymetallic anomalous zone of Jiaocheng district lay in the out-inside contact zone of the rhyolitic crystal tuff lava of Upper Jurassic Nanyuan Formation and feldspar granite in the first phase of third intrusive in the waste Yanshan Movement and has a close relation with the northeast and the northsouth trends and quartz veinlet belt.The larger silver-polymetallic anomalous zone is discovered five mineralization alteration veins and several ancient mining holes in the surveyed area,which has a good ore-finding perspective.
