Spectral interpretation of late-stage mare basalt mineralogy unveiled by Chang’E-5 samples

open access: yesNature Communications, 2022
Laboratory spectroscopic and X-ray diffraction analyses on the Chang’E-5 lunar soil samples have demonstrated that the spectral features of lunar late-stage mare basalts are representative of iron-rich high-Ca pyroxene rather than olivine.
