Fig. 6: Maximum water contents of anorthites (this study) and other NAMs from ungrouped achondrite meteorites²³, angrites⁵⁷, the Moon^33,56,58,68 and the Earth^11,69.

Anorthites of ABL 001 and ON 001 were simultaneously analyzed by FTIR, see Supplementary Figs. 6, 7. Three ungrouped achondrite olivines are from three individual parent bodies. Two lunar feldspars (K-feldspar and anorthites) from ferroan anorthite and Mg-suite troctolite were analyzed by Mills et al. 2017 and Hui et al. 2017^33,58and the feldspar and olivine from CE5 lunar soil were reported by Zhou et al. 2022⁶⁸.
