摘　　要：宁蒗白牛厂矿区位于区域性牛窝子－罗卜地帚状构造的内旋断裂带——白牛厂弧形断裂的拐折部位。由白牛厂弧形断裂伴生的低级次白牛厂帚状断裂构造带，为本区矿液运移和矿体赋存提供了良好通道和有利空间。在白牛厂喜马拉雅期含矿隐伏斑岩体与其围岩（Ｐ１灰岩）的外接触带的构造叠合地段，有望形成斑岩体外接触带热液型铅锌（银）多金属矿床。矿区铅锌矿化主要受控于白牛厂背斜轴部及其以西的白牛厂帚状构造的各弧形断裂带（以ｆ３、ｆ４、ｆ５为主），尤其是其弧形拐折至收敛地段。AbstractThe Bainiuchang ore field of Ninglang is located in the turn part of the inner rotation fault zone(Bainiuchang arc-form fault) of the regional Niuwozi--Lobudi broom-like structure. The associated secondary Bainiuchang broom-like fault structure zone of Bainiuchang arc-form fault provides the good channel and advantageous space to the ore liquid moving and ore body occurrence in this area. And the hydrothermal Pb-Zn(Ag) polymetallic deposit in the outer contact of porphyry body can be formed in the structural superimposed section of the outer contact between the Bainiuchang Himalayan ore-bearing blind porphyry body and its wall rock(P1 limestone). The Pb-Zn metallogenesis in the ore field is mainly controlled by the axis of Nainiuchang anticline and the arc-form fault zone (mainly f3,f4,f5) of the west Bainiuchang broom-like structure, particularly the section from its arc-form turn to convergence.
