摘要
本文基于30余种化学元素的分析,提出了黄海沉积物元素区域分布的5类格局;划分出5种地球化学区;论述了构成区域分布格局的5个主要因素。
More than 30 major and trace elements in sediments from the Yellow Sea have been determined by means of atomic absorption spectrophotometer and X-ray fluorescence analyzer. Based on a detailed study of regional distribution of the elements, 5 kinds of distribution patterns have been proposed and five geochemical provinces can be classified. Except for 'transition' region. there are Ca-Sr-high and Rb-low, K-Rb-high and Ca-low, Fe-Zn-high and Sr-low, Mn-high, and Ca-Fe-moderate provinces. Each one is in accordance with a certain sedimentary environment. Factors causing the distributions of elements are mainly sediment type, hydrodynamic condition, material source, physical-chemical environment and biological action.
