Fig. 3: Representations of bulk compositional spaces for lunar samples.

From: Genesis and timing of KREEP-free lunar Mg-suite magmatism indicated by the first norite meteorite Arguin 002

a Sm vs Sc diagram; b FeO vs Th diagram. The bulk composition of Arguin 002 is highlighted using orange pentagrams. Compositional spaces (FHT, PKT, maria) defined by returned lunar samples and the compositional data points of 278 lunar meteorites71 and Apollo-15 Fe-norites17 are plotted for comparison. A number-density plot technique is employed, where brighter colors indicate higher concentrations of data points, reflecting a greater number of meteorites in those regions. The diagrams are adapted from71,72.
