| Abstract: | Based on the oxide content of macroelements in paleosoil and sandy loess, maingeological features and sporopollen data along the loess profile, the paleoclimate environment of 1. 19Ma.B.P. when the loess formed and its evolution later on, and the relationship between paleoclimateevolution and variation of element content have been described. |
