Abstract
The concept of depositional accommodation has been applied to sequence genesis analysis and sequence di- vision for continental rift basins with examples from Paleogene, Bohaiw an basin.The developing process and its major characteristics of a sequence, a qarasquence set and a parasequence in a continental rift basin can be in- terpretted respectively according to the changing of new space added during the 2nd, the 3rd and the 4th order episodic tectonic subsidence in corresponding to the volume of sediments supplied.Conditions to fo rm bounded surfaces of sequences and systems tracts can also be described and understood through an analysis of deposi- tional accommodation changes.As a result of accommodation evolution analysis, a new concept, the turn - round surface of accom modation variation, has been introduced and applied to recognize boundaries of se- quences and systems tracts.
