海洋沉积物中磷的地球化学特征

本文通过中太平洋西部海区、黄海和苏北海域沉积物中磷含量的分布变化,探讨不同海域沉积物中磷含量与水深、沉积类型、悬浮体,水动力、有孔虫化石等因素之间的关系,并初步探讨大洋、近海、河口等沉积物中磷含量分布的模式。

GEOCHEMICAL CHARACTERISTICS OF THE PHOSPHORUS IN MARINE SEDIMENTS

This paper inquires into the relation of sediment phosphoric contents with water depth, sedimentary type, suspended material, hydrodynamics, and fossils of foraminifera fete by analying, its distribution variation in the sediment samples taken from the western Central Pacific Ocean, the Yellow Sea, the East China Sea, and the offshore area of Northern Jiangsu. The distribution models of phosphoric contents in the oceanic, offshore, and estuarine sediments are diseu--ssed. Meanwhile, the analysis of the core sample shows that vertical distribution variation o?" phosphorus can be used as one of the indexes of paleoclimate.
