MAGNETIC SUSCEPTIBILITY VARIATION IN SEMI-ARID REGION OF NORTHWESTERN CHINA

Our recent study in northwestern China indicates that the variation of magnetic susceptibility does not coincide with the role in the Chinese I.oess Plateau. The environment magnetism investigation in the northeastern margin of the Qilian Mrs shows that there is no obvious difference in ferri-magnetic minerals between Chinese Loess Plateau and semi-arid region of northwestern China. Here we suggest the grain size of magnetic particles may be the potential contributor to the variation difference.
