Abstract: Elemental analysis by measurement of muonic X-rays shows great potential for analyzing the elemental composition of a bulk material at a specific depth without sample destruction. For quantitative analysis, muon capture probability is the most important parameter. In this work, the muon capture ratios and muonic X-ray intensity patterns of metal oxides for geochemically and cosmochemically important compounds, MgO, CaO, MnO and Fe<subscript>3</subscript>O<subscript>4</subscript>, were determined. The muon capture ratios of Ca/Mg and Fe/Mn were proportional to the mixing ratios of CaO/MgO and Fe<subscript>3</subscript>O<subscript>4</subscript>/MnO. From this relationship, the elemental composition can be determined from the muonic X-ray intensity ratio alone. [ABSTRACT FROM AUTHOR]
