摘要
通过对中、新生代兰坪—思茅地洼盆地东、西部沉积特征、岩浆活动、地球物理场和卫星影像资料的综合研究与对比分析,论证了盆地内中轴断裂带的地质特征;讨论了中轴断裂带对盆地演化和成矿作用的重要意义。它是该区深部动力作用的主导构造 ,又是该区超大型、大型矿床形成的主要控制因素。
Comprehensively studying and comparing the features of the sedimentary and magmatic activities, geophysics and Landsat imagery in the eastern and western parts of the Lanping-Simao Mesozoic-Cenozoic Oiwa Basin,this paper infers the characteristics of the longitudinal axial fracture zone in this basin。The authors also point out that the longitudinal axial fracture zone is significant to the development of the basin and the metallogenic process, and is also the major structure controlling the deep dynamic process and the mantle-crust compound mineralization.
