It is emphasized that the first flooding surface (FFS) is used as a standard or useful marker in optimizing chronostratigraphic and lithostratigraphic boundaries.

在年地方面，进一步强调以初始海泛面(FFS)作年地“”标准。

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

沉积序界面处沉积间断时间相对超序界面要短，与岩石地单位界面往往不一致。
