英文摘要Postglacial stratigraphy and environmental evolution onshore and offshore the modern Yellow River Delta were investigated and analyzed through similar to 1200-km high-resolution seismic profiles and four bore holes together with previous publications. Four seismic units (SU 1-4, top-to-bottom) that are bounded by seismic surfaces (T-1-T-4) were identified in seismic profiles, while four depositional units (DU 1-4, top to-bottom) were recognized in representative boreholes. These seismic units and depositional units exhibit good correlation. We interpreted SU 1/DU 1 as the modern Yellow River Deltaic deposits, SU 2/DU 2 as the Holocene neritic sediments, SU 3/DU 3 as a Pleistocene-Holocene transitional layer, and SU 4/DU 4 as the lowstand fluvial sediments. Apart from T-1 (seafloor), T-2 (deltaic base), T-3 (shoreface ravinement) and T-4 (transgressive surface) all dip seaward, but their dipping gradients reduced from T-4 to T-2. Therefore, the thicknesses of SU 2-3 were observed seaward-thicker trends presumably in relationship with different spatial sedimentation rates. Additionally, down-core distributions of environmental proxies (e.g. grain size, microfossils and geochemical characteristics) reveal the transgression system (DU 2 and 3) can be further subdivided into 5 intervals associated with sharp environmental changes.
