南海是西太平洋边缘海之一,研究其海底表层沉积物中元素的地球化学分布特征,将有助于了解南海的沉积模式和元素从大陆到海洋的运移与沉积规律,以及新生代以来南海地区沉积作用的演化。本文将通过因子、点群及趋势面分析,对南海北部的沉积环境进行分区,并初步研究一些有代表性元素的空间分布规律,探讨南海的物质来源。 The South China Sea is one of the marginal seas in the western Pacific Ocean. Studying the geochemical distribution of the elements in its surface sediments will help to understand the depositional pattern of the South China Sea and the migration and deposition of elements from the mainland to the oceans, and the South China Sea Regional evolution of sedimentation. In this paper, the sedimentary environment in the northern South China Sea will be zoned by factor, point group and trend surface analysis, and the spatial distribution of some representative elements will be preliminary studied to explore the material source of the South China Sea.
