珠江三角洲平原区第四纪沉积物地球化学特征及其控制因素
Element geochemical characteristics and controlling factors of the Qua-ternary Sediments in the Pearl River Delta plain
摘要
Abstract
Based on multi-purpose regional geochemical survey in Pearl River Delta Economic Zone, quaternary sediments of 44 cores were emplaced in the Pearl River delta plain. Totally 39 elements and indicators for soils and sediments were determined. According to the characteristics of this area, we firstly carried out the study of geochemical characteristic of delta formation evolution. The results indicate that the average concentrations of most elements in sediment were significantly enriched, the heavy metal elements Cd、Hg、Cu、Pb、Zn、Ni、As have accumulated remarkably, especially. Element type and enrichment degree are distinguishing in different area of the Pearl River delta pain. The main enrichment areas are West River and North River alluvial, Tan River and East River alluvial are the background area;the main factors that control the element contents of sediments in this area are the source material and the change of sedimentary environment.关键词
