1. Weathering and pedogenesis of rocks are important sources of mineral elements for ecological systems, and key processes of global biogeochemical cycling of mineral elements.

2. But, low sedimentary rate in many profiles, especially in S1, and following strong pedogenesis and eluviation would have effect on those climate records.

3. It's found that there is either difference or corresponding relations between soil taxonomy and pedogenesis classification.

4. In the warmer and wetter climate conditions, the paleosol layer grows with strong pedogenesis and abundant rainfall.

5. The fine sands in the Onqin Daga Sandy Land may be in part caused by the pedogenesis occurring under the relatively humid conditions.

6. It was observed that the magnetic susceptibility profile in soils related to the latitude, magnetic base of the parent materials, climatic condition, soil pedogenesis and ripening.

7. The ancestors have done a large number of studies about climate changes and soil pedogenesis of the Loess Plateau, and have obtained wealth of research results.

8. T analysis can sensitively reflect magnetic transformation during heat treatment, and this transformation is closely related with strength of pedogenesis of the samples.
