Mineralogical alternation of thermally treated siderite in air atmosphere has been systematically analyzed by Mossbauer effects. It was preliminarily estimated from the area of sub-spectra that 4% , 39% and 62% of magnetite were formed at 410℃, 490℃ and 510℃ respectively. After being incrementally heated at 530℃ the spectra consist of two sextets of Fe3O4. Sextet of γ-Fe2O3 with hyperfine field of 50T was observed at 550℃. Spectra at 580℃ consisted
