【 摘 要 】

Applications of the magnetic properties of rock continue to be developed because of its ability to integrate the understanding of the variation patterns of minerals and chemical elements in the process of soil formation and also their influence due to external factors . The primary objective of this study is to knowlege how the trends of variations of the magnetic properties and chemical elements on soil profile in landslide area, and how the association between the element as welpalal as the association between chemical elements and magnetic properties. Eleven soil profiles are the focus for the study of magnetic properties (parameter of magnetic susceptibility) and their elemental content (i.e., using the X-Ray Fluorescence, XRF). From the soil profiles studied, one hundred and twenty-four samples were taken and analyzed for their magnetic properties and elemental content. The results of this finding show that the trend of variation in magnetic susceptibility and chemical elements in soils differs from the normal soils and soils affected by human activity. The linear correlation between χLF and χFD values indicates that the soil profile in this study is a natural soil profile even though it has undergone changes due to landslides.
