摘要
构造沉降是陆相盆地层序形成和演化的关键因素，不同序次的构造幕控制不同序次的层序地层单元的形成和演化．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陷盆地在拉张、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。
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.
