塔里木盆地自震旦系—第四系可划分为3个巨层序组,6个Ⅰ级层序(巨层序),16个Ⅱ级层序(超层序)和42个Ⅲ级层序(层序)。3个巨层序组反映了区域构造发展的3个大地构造旋回及其相应的区域大地构造事件在其巨层序组演化过程中的影响。其中,Ⅰ级层序属于同一构造运动体制的产物;Ⅱ级层序属于同一构造背景下的同一期盆地演化或属于同一较长周期海平面变化旋回的产物;Ⅲ级层序属同一期盆地中同一构造演化阶段或受短周期的海平面旋回性变化、沉积物供给速率变化控制。层序地层的研究表明,构造作用在大部分层序形成中起着决定性的作用,表现在不但高级别的层序地层单元主要受大区域性构造作用的控制,许多较低级的层序地层单元也受小区域构造作用的控制。全球海平面的变化往往在某些盆地稳定演化时期起着重要的作用。
The Tarim Basin from the Sinian - Quaternary can be divided into three giant sequence group, six Ⅰ-level sequence (giant sequence), 16 Ⅱ-level sequence (super-sequence) and 42 Ⅲ sequence (Sequence). The three meso-sequence groups reflect the influence of three tectonic cycles of regional tectonic evolution and their corresponding regional tectonic events in the evolution of its meso-sequence group. Among them, the first-order sequences belong to the same tectonic movement system; the second-order sequences belonged to the same basin evolution in the same tectonic setting or belong to the same long-period cyclic sea level cycles; The same tectonic evolution stage or by the short cycle of the sea level cyclical changes in sediment supply rate control. The study of sequence stratigraphy shows that tectonism plays a decisive role in the formation of most of the sequences. It shows that not only the high-level sequence stratigraphic units are mainly controlled by the large regional tectonics, but many lower sequence stratigraphy Cells are also controlled by the tectonics of small areas. Changes in the global sea level often play an important role in the steady evolution of some basins.
