Nonmarine sequence stratigraphy is used to analyze Jurassic depositional sequences in Tu-ha basin, and three sequences and one supersequence are divided in this paper.

本文应用陆相层序地层学方法对吐哈盆地侏罗层序进了综合，出三套层序和一套超层序。

Compared to supersequence boundaries, the depositional hiatus at sequence boundaries is shorter and sequence boundaries are not compatible with lithostratigraphic unit boundaries.

层序界面处间断的时间相对超层序界面要短，与岩石地层单位界面往往不一致。
