摘要
宁德下洋伊利石矿呈脉状产出,贮存于晚侏罗世南园组火山碎屑岩石中,共发现有3个矿体。矿石可分为石英-伊利石型及叶蜡石-伊利石型。矿体受北东向断裂控制,由火山碎屑岩经过热液交代形成。
The Xiayang illite ore acts like a veiny and exists in the late Jurassic Nanyuan Formation volcanic clastic rock. Three orebodies are found. The orebody can be divided into quartz-al bite and pyrophyllite-illite type. The orebody is controlled by NE trending faultes. The ore- bodies formed from volcaniclastic rock by hydrothermal metasomatic formation.
