摘要

Abstract

Sedimentation of fine-grained deposits on coastal zones and continental shelves are important because of the association with chemical pollutants

and the implication to the impact on biological processes

the stratigraphic correlations

and changes in sedimentary environments. The Yellow Sea continental shelf receives large quantities of sediment from the Huanghe (Yellow) River. Unfortunately

little attention has been yet paid to the sedimentation on the shallow shelf and its features

and the vertical sediment flux in the area is poorly understood. In this study

nine cores were collected in northern Yellow Sea by theR/V Science 1 in September

1998 and 1999 to examine the sedimentation rate

sediment flux and the provenance with210Pb analysis. The210Pb activity profiles showed that the vertical sediment flux ranged from 0.06 to 1.18 g/cm2·a in the region. In central part of the area

there was a patch of fine-grained mud

with the flux below 0.33 g/cm2·a. Most profiles were featured in two-segment model. Differences in the profiles reflected spatial and temporal variations in hydrodynamic and sedimentary processes. In order to determine the provenance and sedimentary setting in the area

the geochemistry of Ca

Ti and Rb in 11 surficial sediment samples were studied

which showed that in the central northern Yellow Sea

the mud deposit was from multi-source but mainly from the Huanghe River.
