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

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.
