Magnesium K X-ray emission spectra of Mg, MgO, and olivine [(Mg,Fe)2(SiO4)] are measured using an electron probe X-ray microanalyzer (EPMA) and an X-ray fluorescence spectrometer (XRF). It is demonstrated that the fine structures in the low energy side of the Kα X-ray emission spectra resemble the genuine X-ray absorption spectra which are measured using a soft X-ray synchrotron radiation beam line. Radial distribution of atoms in metallic magnesium is obtained by the Fourier transform of the measured XRF spectrum. Based on the above experimental results, we propose a convenient X-ray absorption spectroscopic method using an EPMA. Using this method, X-ray absorption spectra of a local area as small as a diameter of a few tens of μm is observable within a few hours of measuring time.
