Abstract
Four slope breaks including three ramp breaks in the northeastern part and one steep slope break in the southwestern part of the basin have been distinguished on the basis of the integration of tectonic setting,sedimentary background,palaeobathymetry,stratigraphic thickness,sedimentary facies and seismic profiles.These slope breaks have exerted an influence on the distribution of delta-front sandstones and turbidity sandstones.
