摘要用电子探针微区成分分析(EPMA)方法来测定矿物岩石的微区成分已经是当前岩矿分析的常用方法,但EPMA不能直接测定矿物中的FeO和Fe2O3。通过探讨电子探针分析中影响氧和铁峰位的一些主要因素,结合计算机峰形拟合软件的应用,提出了峰形拟合直接测铁法测定FeO和Fe2O3质量分数的方法。本方法适用于硅酸盐矿物中Fe2+和Fe3+的定量分析,通过实例详细地介绍了本方法的使用过程,并讨论了本方法的可靠性。 Electron probe microanalysis（EPMA） method has been commonly used to determine compositions of rocks and minerals,but the contents of FeO and Fe2O3 in minerals cannot be directly measured by EPMA.The effect of oxide species and accelerating voltage on peak positions of O-kα and Fe-kα is discussed in this paper.The peak shape fitting method for quantitative determination of FeO and Fe2O3 by electron probe microanalysis was proposed with computer software applications of peak shape fitting.This method is suitable for quantitative analysis of Fe3＋ and Fe2＋ in silicate minerals.These examples on content determination of FeO and Fe2O3 in iron pyrope and andradite garnet are described in detail by using the method.The measurement results show good reliability.
