Abstract This paper studied element distribution in aqueous phase, sulfate phase and carbonate phase in the vertical profiles of soil for the salt section along the Tuwu-Yandong metallogenic belt in Eastern Tiansan. The authors revealed the mode of the influence of alkaline geochemical barrier composed of alkaline salts on the distribution of elements in the soil. The existing forms and distribution of elements in the supergene zone is obviously influenced by the alkaline geochemical barrier. Ca, K, Na are in different positions of salt deposition, and the sections of the alkaline geochemical barrier have different types, so that the distribution of elements differs in the vertical profile of soil.
