英文摘要	Rock-magnetic properties were systematically measured on thermal oxidation products of siderite samples that were collected from Dalizi iron deposit, Jilin province. It was revealed that the isothermal remanent magnetization (IRM), remanence coercivity (H-cr) and Curie temperature (T-c) of siderite samples varied with different thermal treatment temperatures. Maghemite (gamma-Fe2O3) was found to be one of the intermediate products during siderite oxidation in air atmosphere, and with relatively high thermal stability. The mineral transformations indicated by rock-magnetic methods were proved by the X-ray diffraction (XRD) and Mossbauer effect experiments. The crystalline structure transitions during the siderite oxidation processes might affect the magnetic properties of oxidized siderite samples.
