Pedological and stratigraphic observations indicate that there is one paleosol layer on the Holocene loess profile in DPG site,Co. Xiangfen of Shanxi province. CaCO₃ , TFe and clay analysis prove that pedological process started at the beginning of the Holocene Magathermal. The major pedological process developed between 4450～3100aB.P, when climate was humid and stable, ancient people cultivated here and created the splendid culture of Taosi . The leaching of CaCO₃ existed during the pedological process . The illuvial depth of CaCO₃ is about 1.1m . The pedogenesis is not intense overall due to deep slope on palaeo-alluvial-pluvial fans. The type of paleosol here can be regarded as the one of Heilutu soil.
