| Abstract: | From an analysis of the contents of geochemical elements and their vertical distribution of the core samples from Yinchuan Basin and the stratigraphic lithologies a zonation of the geochemical elements has been determined. Combining this with spare-pollen data,a discussion of the paleoclimate and paleoenvironment and their evoluation in the basin. Since the middle and late Quaternary has been maded. |

| Keywords: | Yinchuan Basin distribution of geochemical elements sedimentation environment and paleoclimate |
