海河平原北部地区山前-滨海表层土壤地质地球化学特征

Geologic and geochemical evolutive feature of topsoil in northland of Haihe River piedmont plain to coastal plain, China

摘要: 对海河平原北部地区不同地质地貌类型的表层土壤粒度、矿物成分和元素地球化学进行了研究，结果显示，从山前至滨海表层土壤地质地球化学特征与原生沉积环境的相关关系，在空间上表现出随着地质地貌和沉积环境特征的变化而演变的规律。

Abstract: This article is based on the analysis of top soil powder size, mineral composition and element geochemistry character in the different types of geomorphology in northland of Haihe plain. The result shows that the geologic and geochemical characteristics of top soil from piedmont plain to coastal plain are controled by depositional environment, and the characteristics chang with the geomorphology and sedimentary environment.
