Abstract The Middle and Upper Hanjiang Formation in the Pearl River Mouth Basin contains large scale siliciclastic deep-water,gravity-flow deposits. Gravity-flow deposits of the Middle and Upper Hanjiang Formation comprise a regional transgressive-regressive megacycle,which can be further classified into six sequences bounded by unconformities and their correlative conformities. A series of incised valleys or canyons and erosional-depositional channels are identifiable as marks of the major sequence boundaries which might have been formed as the result of global sea-level falls. Besides, prograding clinoform, bottom boundaries of fan lobes and relative low content of calcareous nannofossils are conducive to identification of sequence boundary. Not only the sequence architecture but also the depositional unit is different at various basin locations. Five gravity-flow depositional elements in the slope have been identified as follows: Turbidite channel complexes,lower slope fans,submarine canyon,prograding clinoforms and pelagic sediments. Turbidite channel complexes are divided into five depositional elements: Basal lags,channel and levee system,slumps,lateral accretion packages and telophase filling. Three types of channels are classified: Erosional,erosional-aggradational and aggradational,geometries of which changing along with gradient.
