| 摘 要： | 在详细研究组成内陆叠合型盆地的各个单型盆地的沉积体系三维构成的基础上 ,采用动态成因地层和层序地层分析方法 ,恢复了叠合型内陆盆地的成因地层格架 ,并根据各类等时地层界面的构型 ,将盆地地层序列划分为 7个沉积幕、3个构造沉积幕。进而分析了内陆盆地在同生裂陷和衰减坳陷等不同阶段的充填过程。

| Abstract: | On the basis of detailed study of the tri-demension configuration of the depositional system of every single-stype basin which make up the overlapped-stype inland bain,we recover the genetic stratigraphic framwork of the inland basin by the means of the dynamic genetic stratigraph and sequence stratigraph analysis and divide the stratigraphic sequence of the inland basin into seven depositional episodes,three tectono-depositional epsisodes according to the configuration of all kinds of chronostractigraphic interface ,and then,aualyse the filling course of the inland basion on the different developing stages,such as followillg fissuve-collapse and weaking downwarp. |
