This paper deals mainly with the content and distribution of chemical elements in different types of paleosol in loessial section of Luochuan, and the geochemical characteristics of elements in their translocation or accumulation process during process of soil formation from loess to paleosol. Comparing with parent material (loess), the average contents of Al, Fe³⁺ and K of the paleosol are higher than those of loess; whereas the average contents of Ca, Fe²⁺ and Na are lower than those of loess. The contents of AI, Fe³⁺, K in paleosol profile increase from bottom upward, and the highest value appears in the argillic layer, but the CaCO₃ content is lowest and caliche horizon is evident.
