摘　　要：锡钨矿体产于志本山岩体外接触带、上寒武统核桃坪组下段砂板岩层间破碎带的蚀变闪长—辉长岩脉带中,少数矿体产于岩体内接触带上。矿床成因属于与混合岩化后期派生岩浆有关的高—中温热液矿床。The Sn - W ore body is in the altered diorite - gabbro vein zone in fracture zone of Upper Cambrian Hetaoping Formation Lower Member sandy slate of outer contact of Zhibenshan rock body. A few ore bodies are in the inner contact of the rock body. It belongs to the high - middle T hydrothermal deposit in relation to the later derived magma of migmatization.
