摘　　要：杨林坳钨矿床为岩浆热液石英细脉带型,发现了新类型的岩脉型钨矿。主要容矿岩石为花岗斑岩。通过对岩脉与矿(化)体时间关系、空间关系及其成因关系的讨论,岩浆活动在钨矿成矿过程中不仅提供了热能,还提供了成矿物质和容矿岩石,得出杨林坳矿区花岗斑岩岩脉是成矿有利部位,是该地区找矿的重要新标志。Yanglinao tungsten deposit is a magmatic hydrothermal fluids quartz fine vein band type mine,it is a new dike-type tungsten ore.The host rock is granite porphyry.It is discussed the time relationship,spatial relationship and its genetic relationship of dikes and mineralized bodies,and it is concluded that magmatic activity not only provide the heat energy,but also provide the metallogenic materials and host rocks to tungsten mineralization process,therefore,granite porphyry dike of Yanglinao mining area is a advantageous parts for mineralization,it is an important new mark for mineral exploration of the area.
