| Abstract: |
| 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. |
