摘要 坎萨希（Kansanshi）铜矿位于赞比亚北部赞比亚铜矿带西部,为大型铜金铀等多金属矿。矿床产于新元古界含膏岩碳酸盐岩变质地层中,成矿期为晚寒武世（513~511 Ma）。在古封闭海和海湾环境下形成了铜的预富集层位,新元古代达马拉—卢菲利安（Damalan-Lufilian）弧造山活动后期的退变质作用及热液作用形成铜的矿化,铜矿化主要产于前寒武纪片岩的构造发育部位。 Kansanshi is a large Cu-Ag-U deposit located in the western part of the copper belt.It occurs in the gypsum-bearing carbonate stratum and was formed in Late Cambrian（513~511 Ma）during which retrograde metamorphosed and hydrothermal filling mineralization took place based on pre-enriched copper strata at Neo-proterozoic Damalan-Lufilian arc.Mineralization is mainly developed in Pre-cambrian schist.
