南丹铁陨石样品的X射线荧光微区扫描研究

Study of Nandan iron meteorite by X-ray fluorescence micro-scanning analysis

利用同步辐射和转靶X光机的X射线荧光微区扫描装置对南丹铁陨石的一些特征区域进行微区X射线荧光扫描分析,给出了As、Au、Ca、Co、Cr、Cu、Fe、Ga、Ge、Mn、Ni、Os、Pt、S、Se、Ti、V和Zn等元素的微区分布和定量结果,对实验方法作了讨论。

The X - ray fluorescence micro-scanning analysis of some typical regions in the Nandan iron meteorite was made by means of a synchronous radiation device and a rotating target X-ray generator. The micro -region distributions and quantitative results of As,Au, Ca, Co, Cr, Cu, Fe, Ga, Ge, Mn, Ni, Os, Pt, S, Se, Ti, V and Zn were given. The related expe -rimental technique was discussed.
