摘　　要：元坑钨锡多金属矿区位于佐坑幅北部,位于武夷成矿带粤东段,紫金-博罗大断裂与莲花山断裂带西带夹持区域。该区为一个受断裂构造控制的岩浆热液充填交代型矿床。矿体赋存于与岩体接触带附近且受断裂构造改造的下侏罗统青坑组变浅海潮坪相砂岩中,北东向断裂及北西向断裂构造,具有硅化、角岩化、绿泥石化等地段是重要的找矿方向。The Yuankeng tungsten tin polymetallic mining area is located in the northern part of the Zuokeng area,in the eastern part of the Wuyi metallogenic belt in Guangdong Province,sandwiched by the Zijin Boluo fault and the western belt of the Lianhuashan fault zone.This area is a magmatic hydrothermal filled metasomatic deposit controlled by fault structures.The ore body is located in the shallow tidal flat sandstone of the Lower Jurassic Qingkeng Formation near the contact zone with the rock mass and has been altered by fault structures.The northeast and northwest trending fault structures have important prospecting directions,such as silicification,ceratopsization,and chloritization.
