维尔等人(1988,1989)提出的层序地层立体模式,可以说是他们的层序地层学新概念立论的基础,也是他们赖于进行地层和岩相解释的依据。然而,这一模式的实质,仍未超越传统地质概念的范畴。除了术语上的差别外,它与经典的海进-海退旋回性层序模式没有根本的差别。

The 3-D pattern on sequential stratigraphy proposed by Vail et. al (1988, 1989) can be considered as a basis on which their new idea of sequential stratigraphy is established. It is the same pattern relying on which they make stratigraphic and lithologic interpretations. As a matter of fact, such a pattern does not go beyond the scope of the conventional geological concepts yet, and it also does not substantially differ from the classic cycle sequence pattern of marine onlap and regression with the exception of terminology.
