摘　　要：上杭盆地是形成于中生代期间的陆相走滑拉分盆地。上杭拉分盆地的形成与演化与紫金山金铜矿床的控矿断裂和铜金矿化的形成密切相关,盆地边界主断裂和控矿断裂均经历了挤压—拉张—挤压的构造过程。紫金山金铜矿床的成矿物质、成矿流体的物质来源与上杭盆地早白垩世火山岩相同,具有壳幔混熔特征。Shanghang basin formed in Mesozoic is terrestrial strike-slip pull-apart basin. It is considered that formation and evolution of the basin is closely associated with ore-controlling faults and mineralization of Zijinshan copper-gold deposit. The main fault of basin boundary and ore-controlling faults underwent compressional-extensional-compressional evolution. And the source of ore-forming material and fluid are the same with the one of early cretaceous volcanic rock in the basin, which has characteristic of the mixed-meltinz of Crust-Mantle.
