塔里木盆地晚泥盆世—石炭纪为远离陆棚边缘的陆棚内部碎屑岩和碳酸盐岩陆表海沉积环境,在层序地层分布模式上与Vail等根据被动大陆边缘盆地提出的层序地层分布模式有所不同。共将上泥盆统—石炭系划分出五个层序,十四个体系域。其中,第I层序是在快速的海平面上升和陆源碎屑物质快速补偿条件下形成的;第Ⅱ层序代表陆源物质补给由快变慢的条件下形成的;第Ⅲ层序代表海面由慢速上升至快速下降过程中且陆源物质补给相对稳定条件下形成的;第Ⅳ层序代表海平面快速上升与陆源物质补给相对稳定的条件下形成的;第Ⅴ层序是在快速海平面上升及陆源物质供给补偿不足的条件下形成的。塔里木盆地晚泥盆世—石炭纪的沉积史是在相对海平面呈阶段性上升的海侵过程中发生的,可将这一时期的海平面变化划分为五个二级周期旋回。其中构造作用对第I、I、V周期的形成起了重要的作用。
The Late Devonian-Carboniferous in the Tarim Basin is a continental shelf clastic rock and carbonate sedimentary environment far away from the shelf margin. Based on the sequence stratigraphic distribution model and Vail et al., The sequence stratigraphy sequence proposed by the Passive Continental Marginal Basin Distribution patterns are different. The Upper Devonian-Carboniferous is divided into five sequences and fourteen systematic domains. Among them, the first sequence is formed under the condition of rapid sea level rise and rapid compensation of terrigenous clastic matter; the second sequence represents the terrestrial material recharge from fast to slow; the third sequence represents the sea surface from Slowly rising to rapid descent and relatively stable terrestrial material supply conditions; the fourth layer represents the rapid rise of sea level and the terrestrial material supply is relatively stable conditions formed; V sequence is rapid sea level rise And the lack of compensation for the supply of terrestrial material formed. The Late Devonian-Carboniferous sedimentary history in the Tarim Basin occurred during the transgressive process with a period of relative sea level rise. The sea level changes during this period can be divided into five secondary cycle cycles. The tectonic effect plays an important role in the formation of the I, I and V cycles.
