摘要
通过对南盘江盆地不同时期沉积体系构型的时空演化和不同时期沉积组合特征分析 ,南盘江盆地是在扬子地台南缘基础上 ,发展起来的断陷盆。三叠纪 ,盆地演化经历了一个由拉伸作用形成的断陷盆、构造挤压形成的扰曲盆地和挤压隆升暴露于海面之上的完整构造旋回过程。盆地演化可分为稳定阶段、拉伸阶段和反转挤压三个大的演化阶段。
The Napan River Basin is a rift basin along the southern margin of Yangzi Platform, which is shown by the analysis of time-space evolution of system configuration and combination features of the sediments in different periods and the structural evolution stage.In Triassic,the evolution of this basin experienced a complete structural cycle from extended rift basin to compressed flexure one,then rising above the sea level.Therefore,it can be divided into three stagesie,the stable stage;the extended stage and compressed inversion stage.
