兰坪盆地的演化受控于盆地所处的构造背景,经历了中三叠世至早侏罗世的陆内裂谷盆地、中—晚侏罗世的拗陷盆地、白垩纪的前陆盆地、古新世—中新世的走滑盆地。盆内成矿流体特征与盆地性质密切相关,陆内裂谷盆地及拗陷盆地阶段成矿流体沿同生裂断活动,以垂向运移为主;前陆盆地阶段为喜山期的成矿作了物质准备;走滑盆地阶段,由于推覆构造活动强烈,深部流体和浅部红层中的盆地流体的混合,提供了大量的矿物质,并就位于构造圈闭中,形成如金顶铅锌矿等大型矿床。
The evolution of the Lanping Basin was controlled by the tectonic setting of the basin, experienced intra-triassic to early Jurassic intracontinental rift basins, middle-late Jurassic depression basins, and Cretaceous foreland basins , Pliocene-Miocene slip-basin. The characteristics of ore-forming fluids in the basin are closely related to the nature of the basin. The ore-forming fluid in the intracontinental rift basin and the depression basin is mainly composed of vertical migration, and the foreland basin is mainly Himalayan In the stage of strike-slip basin, due to strong nappe structure activity, the mixing of fluids in the deep fluid and the shallow red beds provided a large amount of minerals and was located in the structural trap to form a gold- Top lead-zinc and other large deposits.
