a Mg# of orthopyroxene vs. An# in plagioclase for Arguin 002, Apollo norites/alkali norites/gabbronorites, atypical Apollo-15 Fe-norites, Mg-suite-related clasts in meteorites, and the compositional ranges of typical Apollo Mg- and alkali-suite, and ferroan anorthosites (FANs). Results from thermodynamic calculations for partial melts of Mg-suite analog sources with varying amounts of KREEP are represented by colored curves (Elardo2023:31; Prissel2020:21). b The bulk-rock rare-earth element (REE) pattern of Arguin 002, compared with those of typical Apollo norites/alkali norites/gabbronorites and atypical Apollo-15 Fe-norites. c–e The REE patterns of silicate minerals (clinopyroxene, orthopyroxene, plagioclase) in Arguin 002, compared with the compositional ranges of Apollo Mg-suite, FANs, and Mg-suite-related clasts in meteorites. The typical Apollo data in (a, b) and (c–e) are from4 and12 respectively. The Apollo-15 Fe-norite data are from17. Data of Mg-suite-related clasts in meteorites are from15,18,20,27. The compositional ranges (colored shades) in (a) are from Ref. 31.
