摘    要:构造沉降是陆相盆地层序形成和演化的关键因素,不同序次的结构幕控制不同序次的层序地层单位的形成和演化,根据构造沉降及其可容空间变化特点,重点论述陆相坳陷盆地和裂盆盆地的在拉张挤压和热沉降背景条件下层序的基本构成样式及其沉积特点,同时提出了构造层序和层序的几种可能的成因机制。

关 键 词:陆相盆地  构造层序  幕式构造  层序构成

Abstract:Tectonic subsidence is a key factor controlling the formation and evolution of sequences in continental basin.The formation and evolution of different stratigraphic units of different sequences are controlled dominatly by different scales of tectonic epsodes.Based on the characteristics of tectonic subsidence and accumulation in continental basin,the basic patterns of sequences and their depositional characteristics under extensional,compressional and thermal subside setting in the flexural and rifting basins have been discussed,and some possible geneses of tectonic sequence and sequence are pointed out.
Keywords:continental basin  tectonic sequence  sequence  accumulation model
