Abstract:
      Based on the Holocene loess-soil profile in eastern Guanzhong, we analyzed the content and distribution of Ni, Mn, Cu, Zn, Nb, As, Ti, V, Co and Pb at TSG site and compared with magnetic susceptibility and Rb/Sr. The results showed that the changes of Ni, Cu, As, V, Mn, Zn and Nb were affected by climate change and its pedogenesis environment, Co was contacted closely with soil parent materials, and the sensitivity of Pb into its pedogenesis environment was poor. In the stag e of paleosol period in eastern Guanzhong, the content of soil heavy metals was increased significantly, the warm and humid climate during this period, strong p edogenesis making some soluble elements migration and leaching, leading to relative enrichment of heavy metals in the paleosol.
