冲绳海槽是介于东海大陆架和西北太平洋之间的一个现代沉积凹地,其特殊的地理位置吸引着众多的中外学者争相研究。近年来我们曾对冲绳海槽进行了一系列的海洋地质调查研究工作,本文即为该海槽沉积物地球化学特征的初步总结(调查站位见图1)。
The Okinawa Trough is a modern depositional depression between the East China Sea continental shelf and the northwest Pacific Ocean. Its special geographical location attracts many Chinese and foreign scholars competing for research. In recent years, we conducted a series of marine geological survey and research work on the Okinawa Trough. This paper is a preliminary summary of the geochemical characteristics of the sediment in the trough (survey site shown in Figure 1).
