福建尤溪沉积-改造型矿床地质特征及找矿方向

On sedimentary transformation geological properties and ore exploration in Youxi County of Fujian

主要讨论了福建尤溪县沉积-改造型矿床的地质特征,总结出3种矿床模式:梅仙式层状铅锌(银)多金属矿床、肖坂式脆韧性剪切带型金矿床和龙门场式铅锌(金银)多金属矿床。结合元素特征,论述其构造演化特征和成矿机理,提出了尤溪县沉积-改造型矿床的找矿方向。

The authors discussed the geological properties of sedimentary transformation deposit in Youxi County of Fujian Province, summarized three types of deposit modes： Meixian-type stratiform Pb-Zn （Ag） polymetallic deposit; Xiaoban-type Au deposit of brittle- ductile shear zone ruode and Longmenchang type Pb-Zn （Au-Ag） polymetallic deposit. In combination with element properties, the au- thors depicted the structural evolution properties and metallogenic mechanism, put forward the ore exploration orientation for sedimenta- ry transformation deposit in Youxi County.
