南黄海沉积物的物质来源及运移研究

MATERIAL SOURCES AND TRANSPORTATION OF SEDIMENTS IN THE SOUTHERN YELLOW SEA

依据南黄海沉积物中粘土矿物和地球化学等方面的资料,对南黄海沉积物的物质来源及运移作了深入的探讨。南黄海中、西部主要物质来源为黄河输送的物质,但该区域也不排除来自于黑潮系统所带来的远洋物质。南黄海南端北纬33°以南区域沉积物来源主要为长江源沉积物;南黄海东部沉积物明显受来自朝鲜半岛物质的影响,但南黄海东部泥质区地球化学表明长江物质在该区域也有一定贡献,也包含部分被海水侵蚀的朝鲜半岛沿岸基岩和海底基岩及黑潮物质。

Base on the clay minerals and geochemical data for the southern Yellow Sea, the material sources and transportation of sediments are researched in this paper. While the main material sources of the central and western parts of the southern Yellow Sea are of matter from the Yellow River some are of deep-Sea materials transported by the Kuroshio system. For the area south of 33°N in this region, the sediments mainly come from the Changjiang River. Sediments in the eastern region in the southern Yellow Sea are obviously influenced, by the Korean peninsula, But materials from the Changjiang River also make a contribution to this area, as shown by the geochemistry of the mud there, which also contains seawater eroded coastal and seafloor basement rock of the Korean Peninsula and materials from the Kuroshio.
