摘要

摘要: 研究样品由“向阳红16”号于1992年6～7月间取自冲绳海槽中部.对表层沉积物的地球化学数据的因子分析和典型化学组分的相关分析结果表明,冲绳海槽中部表层沉积物主要包括陆架来源、生物源和火山热液源组分,且以陆源组分为主;运用修正的富集团子(EF)分析结果表明,沉积物中陆源、生物源、火山热液源组分在不同区域的相对分布是显着不同的.

Abstract: The study samples were collected from the central Okinawa Trough during R/V Xiangyanghong No.16 cruise on June to July 1992.The geochemical data of the surface sediments of the central Okinawa Trough are studied by factor analysis and typical components' correlation analysis.The results show that the surface sediments of the central Okinawa Trough are basically made up of terrestrial source, biological source and volcanic and hydrothermal source components.The results of revised EF indicate that terrestrial source, biological source and volcanic and hydrothermal source components vary from area to area.
