河流三角洲的地质学长期以来都基于这样的概念，这里称为“平衡响应假设”，即稳定的外部动力强迫产生稳定的地层构造。尽管这种平衡响应在物理上是可能的，但该假设通常并不成立，并且可能导致对地层记录的严重误解。自动地层学采取了完全不同的观点，它充分考虑了非平衡响应和伴随的确定性自生，表明（1）稳定的动态外强迫通常会导致不稳定的地层响应，（2）稳定的地层构造可能是由不稳定的动态外强迫引起的。进一步探索河流三角洲对外强迫的非平衡响应将使其地层学更加清晰。
The geology of river deltas has long been based on the notion, here referred to as the ‘hypothesis of equilibrium response’, that steady external dynamic forcing gives rise to steady stratigraphic configuration. Though this equilibrium response is physically possible, the hypothesis does not hold true in general and can cause serious misinterpretation of the stratigraphic record. Autostratigraphy takes a totally different view which takes full account of non‐equilibrium responses and accompanying deterministic autogenesis, suggesting that (1) steady dynamic external forcing generally results in unsteady stratigraphic response and (2) steady stratigraphic configuration can result from unsteady dynamic external forcing. Further exploration of non‐equilibrium responses of river deltas to external forcing will bring more clarity to their stratigraphy.
