塔里木盆地实际资料表明:滑脱层与沉积层序之间存在着密切的关系,泥、页岩型滑脱层大致相当于沉积层序中的密集段;膏盐型滑脱层大致相当于沉积层序中低水位体系域部分。在特定条件下,利用两类滑脱层可以帮助识别密集段、低水位体系域和划分沉积层序。

Geological data collected from Tarim Basin indicate that detachment beds are closely related to depositional sequeces.Mudstone-shale detachment is generally corresponding todense section of the depositional sequence; gypsum-salt detachment is roughly equivalent to low-water level system reaml of the sequence. Under certain condition, the two kinds ofdetachment could be used to identify dense section and low-water level system domain and toclassify depositional sequence
