| 中文摘要 | 利用吉林大栗子铁矿纯菱铁矿样品，系统测量了菱铁矿在空气环境的的磁化特征，揭示出其饱和曙剩磁（ＳＩＲＭ）、剩磁矫顽力（ＨＣＲ）和居里温度（ＴＣ）随加热温度升高而秘珠系列变化，菱放氧化中准稳定态性矿物磁赤铁矿是中间产物之一，并且具有较高的热稳定性，Ｘ射线衍射和穆斯堡尔效应等分析结果证实了岩石磁学研究所揭示的菱铁矿氧化中磁性矿物转变过程，菱铁矿氧化过程中结晶结构的转变可能会影响其氧化产物的磁性特性。 |
| 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. |
