摘　　要：扬子地块西缘灯影组层控铅锌矿床是该区最重要的一类矿床。成带分布，受构造控制，具明显的后生特征。所有矿体均产在灯影组碳酸盐建造顶部，并靠近下寒武统砂页岩建造。受岩相组合（地球化学障）的控制，属多源混合后生热液成因层控矿床。根据矿床成因和成矿规律的研究，本区灯影组具备形成超大型矿床的潜力。The stratabound Ph-Zn deposit in Sinian Dengying Formation of the west margin of Yangzi massif is one of the most important types of ore deposits in this area.,It shows zonal distribution, structure controlling, clear epigenetic characteristics, all ore bodies occurred in the top of the carbonate formation of Dengying Formation and near Lower Cambrian sandstone-shale formation, lithofacies (geochemical barrier) controlling and belongs to the polygenetic mixed epigenetic hydrothermal stratabound deposit. According to the study of the deposit origin and metallogenetic rule, the Dengying Formation in thin area has the potentiality of forming super--large ore deposit.
