最近开发的软件（OpendTect SSIS）使我们能够通过地震数据的惠勒变换来研究年代地层框架内地震地层表面的时间属性。在构造域和惠勒域研究地层表面，增强了我们对这些表面的时间属性的理解。最大洪泛面标志着海侵的结束和正常海退的开始，是一个高度等水位的事件。强迫海退的基面对应于强迫海退开始时的海底。这是一个高度均衡的事件，与高位沉积顶部的侵蚀开始和陆上不整合的形成相一致。陆上不整合是一个高度历时性的事件，它开始于强迫海退的开始，当强迫海退的基面形成时，停止于强迫海退的结束，这与相关整合一致。相关整合对应于强迫海退的结束和高度等渗。最大海退面标志着正常海退的结束和海侵的开始。在我们的例子中，这个表面是中等等厚的。
Recent software developments (OpendTect SSIS) enable us to study the time attributes of seismic stratigraphic surfaces within a chronostratigraphic framework by means of Wheeler transformation of seismic data. Studying stratigraphic surfaces in the structural and the Wheeler domain enhances our understanding of time attributes of these surfaces. The maximum flooding surface marks the end of transgression and the onset of normal regression and is a highly isochronous event. The basal surface of forced regression corresponds to the seafloor at the onset of forced regression. This is a highly isochronous event that coincides with the start of erosion at the top of the high stand deposits and the formation of the subaerial unconformity. The subaerial unconformity is a highly diachronous event that starts at the onset of forced regression, when the basal surface of forced regression is formed and stops at the end of forced regression, which coincides with the correlative conformity. The correlative conformity corresponds with the end of forced regression and highly isochronous. The maximum regressive surface marks the end of normal regression and the onset of transgression. This surface is in our case moderately isochronous.
