摘　　要：康定大厂沟金多金属矿点赋存在志留系茂县群中,受左行走滑体系内的剪切裂隙控制,为硅化-金多金属硫化物型矿点。成矿与区内海西期基性岩浆活动有关,矿(化)体在空间分布上受"非典型"Reidel剪切系统模式控制。区内基性岩脉两侧或附近的P,R和R’型剪切裂隙或蚀变破碎带是找矿重点地段。The Dachanggou gold polymetallic occurrences occur in Silurian Maoxian Group and are con- trolled by left slip shear crack system. They are silicified gold polymetallic sulfide mineral occurrences and considered to be related to Hercynian basic magmatism. Spatially the （mineralization） ore bodies are con- trolled by non--typical Reidel shearing model. Based on the above mentioned metallogenic model of the occurrences is built and targets are pointed out at P. R R＇ type shearing fractures or altered eataclastic zones on both sides of or near the basic dykes.
