摘要
昆阳裂谷系铜矿成矿系列可归结为两期火山—喷流—沉积成矿和两期改造、再造成矿。原生喷流—沉积成矿作用是矿化富集的主要因素，也是后期改造、再造成矿作用的基础和前提。矿化富集中心（带）受多期活动的同生断裂（带）控制，表现为多期多类型矿化发育、同位多阶成矿的特点。
The Cu metallogenetic series of Kunyang rift system can be reduced to two Periods of volcanic-effusive-depositional metallogenesis and two periods ofreformatlon metallogenesis.And the primary effusive-depositional metallogenesis is not only the main factor of ore enrichment but also the basis and prerequisite of laterreformation metallogenesis.The ore enrichment centre(zone)is controlled by the cogenetic fault(zone)with polyph8SE activities,which shows the characteristics of the development of polyphase polytype metallogenesis and the Polyphase metallogeneslsat the same site.
