In Han-Xing plain of Hebei Province, the authors used multistage classification principles of the form-causes-lithology to study the Quaternary geomorphologic unit. The geomorphology of the study area was divided into two primary units, nine secondary units and twenty-six grade three units. By using the multi-target geochemical data in Hebei Province, with SiO₂, Al₂O₃, Fe₂O₃, w(Na)/w(Rb), homogenization accumulation of Rb, U and Ga as the indices for Quaternary geomorphologic geological unit division, the division of Han-Xing plain in Hebei Province was conducted. Research proves that these geochemical indicators have an obvious effect in dividing ancient river channel, Zhanghe alluvial proluvial fan, even the stage of Hutuo River fan and the zoning of flood plain area. There is a clear proof in identifying Ningjinbo, Daliuze and Yongnianwa depositional depressions. The experiment based on the element geochemistry for studying geological units has been successfully conducted.
