摘要
In this paper, various measurements of magnetic parameters from MWC were carried out, comparison was made with those of Luochuan profile, which lies in the Central Chinese Loess Plateau (CLP). The types of magnetic minerals are similar to the CLP: magnetite, maghemite, limonite and hematite. However, the magnetic properties of Australian aeolian sediment show quite different. Furthermore this proportion increases along with the depth. Maghemite is more sensitive than magnetite under pedogenic condition of experiencing humid and stagnant watered environment. Maghemite increases along with enhancement of magnetic susceptibility in Luochuan section.
