Abstract:

 This article introduces the theory of lakebasin filling type classification, which was proposed by Bohacs. and Carroll. They had summarized many lakebasin lithofacies, and differentiated them into three typical associations: fluviallacustrine, fluctuating profundal and evaporative. Corresponding to these three lithofacies associations, we also differentiated the lakebasin into three filling types: overfilled lakebasin, balancedfilled lakebasin and underfilled lakebasin. By summarizing the lithofacies and sequencestratigraphic characteristics of QuantouNenjiang Formations of  Songliao Basin, China in the MidLate Cretaceous period, we compared Songliao Basin to this classification of lakebasin filling types proposed by Bohacs and built up a primary framework of Songliao lakebasin filling types in that period, so that we can go deeper to analyze and summarize the characteristics of their source rock distribution and organic matter burial.

Key words: Key words: Songliao Basin; QuantouNenjiang Formations; lakebasin filling type; terrestrial lacustrine sequence stratigraphy; lithofacies association; organic matter burial
