GEOCHEMICAL CHARACTERISTICS OF TRACE ELEMENTS IN THE SURFACE SEDIMENTS OF THE SOUTH YELLOW SEA

Qingdao Institute of Marine Geology, Qingdao 266071, China

摘要

摘要: 分析了在南黄海采集的295个站位的表层沉积物样品的微量元素含量和500个站位的粒度参数,研究了南黄海沉积物微量元素含量、平均粒径和判别函数的分布特征及微量元素、沉积物类型和平均粒径的相关性。南黄海沉积物微量元素分布由于物质来源和与沉积物类型相关性的不同,表现出明显不同的分布规律:Sr分布与黄河、长江和生物碎屑碳酸盐的贡献有明显关系;Ba分布与黄河、锦江物质供给有关;东部Rb元素分布反映了韩国河流沉积物对南黄海东部的影响;Co分布反映了长江物质的运移方向。Ba和Cu与沉积物类型相关性不明显,不受沉积物粒度控制;Sr、Co、Rb则可以用于区分黄河、长江和韩国河流沉积物的来源。

Abstract: The trace element contents of surface sediment samples collected from 295 stations and the grain-size parameters for 500 stations in the South Yellow Sea were analyzed and the distribution characteristics of trace elements contents, average grain sizes, differential functions of sediments in the South Yellow Sea and correlation analysis between trace elements and sediment types were studied. According to the differences of the material sources and correlation between elements and sediment types of sediments in the South Yellow Sea, trace elements have obviously different distribution patterns. The distribution of Sr clearly has something to do with the Yellow River,Yangtze River and biodetritus carbonate. Ba is supplied by the Yellow River and Keum River. Rb element in the eastern South Yellow Sea suffers from the Korean rivers influence. Co distribution reflects transporting direction of matter from the Yangtze River. The distributions of Ba and Cu are not obviously correlated with sediment types and not controlled by the sediment granularity. Sr,Co and Rb can discriminate sediment sources of the Yellow River,Yangtze River and Korean rivers.
