摘要：
Mossbauer spectroscopy was used in order to identify iron oxides responsible for soil magnetism and for changes of the shape of the magnetic susceptibility curves obtained in the thermomagnetic measurements. The chemical composition of the soil samples was transformed due to the thermal treatment through dehydration/dehydroxylation and than oxidation/reduction process. The largest content of the magnetite has been observed for samples annealed up to T (a) = 700 degrees C, which indicates that conversion process occurred under reduction conditions.
