Abstract

Abstract

The studies of tectonics and deposition of depression in the middle part of northern continental slope in the South China Sea were dealt with,based on the sequence stratigraphy and depositional facies interpretation of seismic profiles acquired by cruises of "China and Germany Joint Study on Marine Geosciences in the South China Sea" and "The formation,evolution and key issues of important resources in China marginal sea",and combining with the previous studies in the study area.It is shown that the tectonic evolution of continental slope depressions can be divided into rifting,rifting-depression transitional and depression stages,while their depositional environments change from river to shallow marine and abyssal,which results in different topography in different stages.The topographic evolvement in the study area includes three stages,that is,Eogene,middle stage of early Miocene to middle Miocene and late Miocene to present,in which the infill of depressions during the second stage results in the crucial change of slope shape,and forms the present style of the slope.
