 note = {Recent mineralogical studies of lunar mare meteorites have revealed that most crystalline basalts (i.e. Apollo samples) do not represent primary magma compositions but only represent Fe-rich upper layer of the basalt flow. In contrast, basaltic breccias tend to represent the average (approximately true) basalt composition because they consist of mixtures of Mg-rich lower layer and Fe-rich upper layer of the basalt flow. Thus, basaltic breccias are more suitable to estimate the true basalt composition. The thickness of the basalt included in lunar meteorite MET 01210 is estimated to be 50-100 m. Spectral analysis of a Mg-rich basalt breccia and an Fe-rich crystalline basalt shows that they can be spectroscopically distinguished by lateral shift of reflectance spectra and the associated individual absorption bands. This indicates that the SELENE (SELenological and ENgineering Explorer) multispectral data with high spatial resolution can be utilized to understand vertical compositional variation within a basalt unit and estimate the true basalt composition., 資料番号: AA0063505025},
