Abstract: Songliao basin has experienced several structural movements in its southeast uplift area. And the important impact on hydrocarbon accumulation is the regional uplifting caused by reversal tectonic movement in and after late period of Nenjiang formation. However, the inferior seismic data from shallow strata lead to no clear cognition of its tectonic evolution since uplifting. It is recognized from the marginal facies characteristics in shallow strata in southern Songliao basin that under the process of the compressional tectonic movement by the end of Late Cretaceous to paleogene, Songliao basin appeared features in form of uplift in its east and drop in its west while its uplifting as a whole, and the southeast uplift area is in uplifting situation for a long term.

Key words: Songliao basin, marginal facies, tectonic evolution, uplift process
