【摘要】 根据测定岩芯中^２１０Ｐｂ放射性活度，南黄海东部泥区最高现代沉积速率为１．６５ ｃｍ／ａ，泥区边缘沉积速率为０．１２ｃｍ／ａ。表层沉积物中的化学成分ＣａＣＯ_３，Ｃｕ，Ｓｒ，Ｔｉ和Ｒｂ的 含量表明黄河物源对该泥区没有影响，长江物源对该区贡献较小。更多还原

【Abstract】 The sedimentation rates in the east part of the South Yellow Sea were determined based on profiles of 210Pb in the cores. It ranges from 0. 12 to 1. 65 cm/a. In order to discuss material sources of fine-grained mud in the eastern South Yellow Sea, Chemical elements CaCO3,Sr,Cu,Ti and Rb have been determined. The contents of CaCO3 and Sr showed that the Huanghe River materials could hardly be transported to the eastern South Yellow Sea. The contents of Cu,Ti and Rb showed that parts of terrigenous materials from the Changjiang River were transported to the mud areas. This research was supported by the National Natural Science Foundation of China and Korea.更多还原
