Seven dopositional systems, i.e. the alluvial fan, fluvial,complex delta,beachbar,fan-delta, nearshore subaqueous fan and axial gravity flow channel systems, havebeen recognized in the Paleogene,of the Dongpu depression by means of integrat-ing the geologica, logging, seismic and laboratary data. These depositional systemswere controlled not only by the tectonic activities but also by the paleogeograph-ic settings such as paleotopography, paleoclimate, paleobathymetry and paleosa-linity. Furthermore, the sedimentary settings, petrological, mineralogical and paleo-ntological features,log-probability curves, C. M diagrams, SP curves, seismic reflec-tion features, shapes and distribution of sandbody and sedimentary structure ofthe 7 typas of the depositional systems are introduced. It is pointed out that thestudy area is characterized by complex Paleogene source rocks, stable drainagesystems, obvious fluvial and gravity flow actions. asymmetric distribution of thedepositional systems in plan and inherited vertical evolution of the depositionalsystems. This paper finally summarizes the relation of the fan-delta and axialgravity flow channel sandbody and oil-gas accumulation and points out the direc-tion in petroleum exploration in the futuro.
