supersequence

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.

本陆相层序地层学方法对吐哈盆地侏罗系沉积层序进行了综合分析，划分出三套层序和套超层序。

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

沉积层序界面处沉积间断的时间相对超层序界面要短，与岩石地层单位界面致。
