摘要：98% plagioclase) have large chemical variations in Mg number (Mg# = molar 100 × Mg/(Mg Fe)) of each coexisting mafic mineral.The variations imply that these pure anorthosites underwent complex formation processes and were not formed by simple flotation of plagioclase.The lunar highland samples with pure anorthosite and the PAN observed by Kaguya suggest that pure anorthosite is widely distributed as lunar crust lithology over the entire Moon.
