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断的时超层序界面要短，与岩石层单位界面往往不一致。

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.
