Abstract:
Taking brown soil as research object,through measurement and analysis of magnetic susceptibility of brown soil profile and morphologically different iron oxides，the influence of iron oxides with chemically different morphologies on magnetic susceptibility of brown soil were studied.The results showed that magnetic susceptibility changing trended of brown soil profile generally was that surface soil magnetic susceptibility was the highest，magnetic susceptibility of deposition layer was locally greatened，in the parent material layer soil susceptibility was relatively low.The average frequency magnetic susceptibility of brown soil was 9.08%，so brown soil contains a lot of ultrafine paramagnetic particle produced by weathering pedogenesis.Free iron oxides and amorphous iron oxides were highly significantly correlated with magnetic susceptibility；total iron was significantly correlated with magnetic susceptibility on 60～200 cm layer.In terms of magnetic susceptibility of brown soil，the content of free iron oxides had more influences than that of amorphous iron oxides and organic combination iron oxides.
