摘　　要：通过对兰坪陆相盆地地质资料的综合分析,可将兰坪陆相盆地的演化分为碰撞后裂谷盆地演化阶段、坳陷盆地演化阶段、前陆盆地演化阶段和走滑拉分盆地演化4个阶段。同时对这些演化阶段对应的金属矿床进行了研究,结果发现,兰坪盆地内几乎每一个重要的演化阶段都形成了不同程度的矿化作用,并以此为基础形成了喜山期大规模成矿作用。Based on synthetic analysis of the geological data concerning the Lanping Basin, its evolution procedure was divided into four phases, i.e., the basin acted as a rifting, depressional, foreland or strike-slipping one at its different development stages, respectively. This paper studied the basin evolution of Lanping and its corresponding metal deposits. The results show that metallogeny to a certain degree occurred at almost all evolution stages, and large-scale mineralization took place in the Himalaya period.
