摘要

The measured anisotropy of magnetic susceptibility (AMS)was compared to theoretically derived magnetic fabrics occuring in airflow conditions from Baicaoyuan, Xifeng, Yichuan, Lingtai and Shilou profiles. While for the underlying red clay, the measured AMS apparently reveals that the maximum susceptibilities group in the NW quadrant and the minimum susceptibilities are clustered in the SE quadrant. It evidently shows that westerly jet still played a major role for the formation of the AMS ellipsoid orientation before the Pleistocene.
