【摘要】 杨林坳钨矿是以白钨矿为主的岩浆期后高-中温热液充填交代矿床,白钨矿主要产于上古生界泥盆系杨林坳组砂岩和板溪群板岩中,受断裂构造和不整合面控制明显,岩浆活动为成矿提供了物质来源。文章在分析控矿因素的基础上,对成矿规律进行了探讨,并提出了下一步找矿预测的方向。更多还原

【Abstract】 The Yanglin’ao W deposit,most mineralization of which is scheelite,is a post magmatic deposit formed by high-middle temperature hydrothermal filling and metasomatism.The scheelite deposit mainly occurred in sandstones of the Yanglin’ao Formation and slates of the Banxi Group in Devonian of Upper Paleozoic,which is obviously controlled by fault structures and unconformity surfaces with the ore-forming matters provided by magmatic movements.Based on analyzing ore-controlling factors,it has discussed the ore-forming rules and put forward the predicting direction for further prospecting.更多还原
