| 摘 要： | 从~（57）Fe和~（119）Sn无反冲共振吸收谱分析,配合x射线衍射分析等方法,获知华南某铁矿-多金属矿区,两种铁矿石中磁铁矿的组份。从穆斯堡尔谱峰面积法,推算出非正分的磁铁矿晶体结构式,并由此算出其中Fe~（2+）和Fe~（3+）的含量比。综合矿石产状及铁的氧化态分析,获得不同铁矿石的成因信息。

| Abstract: | The 57Fe and 119Sn recoilless resonance absorption techniques and X-ray diffraction were applied to the study of two kindsof magnetites from a certain mining area of iron-polycomponent metals in South China to realize their constituents. From the peak area method of Mossbauer spectrum, we have deduced the non-stoichiometric crystal structure formulae of magnetites, and subsequently we have calculated the ratio Fe2+/Fe3 + . From the above results and the occurrences of ores, we have obtained the information of the origin of different magnetites. |
