The difference of depositional supply of near thrust belt and far thrust belt made the depositional filling and stacking patterns of parasequences different.

Parasequences are usually too thin to discern on seismic data, but when added together, they form sets called parasequence sets that are visible on seismic data.

Based on the method of parasequences identification with the salt rhythm characteristics, the sequence division accords with the practice in salt formation in Dongpu Depression.
