地幔柱构造与成矿作用——以兰坪盆地为例

ON THE PLUME TECTONICS AND METALLOGENES——Taking Lanping Basin as an Example

以兰坪盆地为例, 根据地幔柱构造特征及地幔柱与陆内矿床间的关系和地幔柱构造对盆地中矿床形成、分布的控制理论, 对兰坪盆地的各种矿床类型与冷、热地幔柱的发展、演化的关系进行分析,认为正由于大陆岩石圈与大洋岩石圈构造体制的相互转化、大陆的分裂与聚合,导致了在地幔柱构造的控制下一系列不同成矿作用的矿床的形成。

Taking Lanping basin as an example, we analyse the relationship between the type of ore deposits and the evolution of mantle plume basing upon the characteristics of plume tectonics, relation ship between plume and inland ore deposits and the theory about plume controlling the formation and distribution of ore deposits. And we believe that the transformation between continental and oceanic lithosphere each other and the opening and closing of continent cause a series different metallogenesis to form ore deposits under the control of plume tectonics.
