Description:
Mg-suite is a series of ancient plutonic rocks from the lunar crust with ages and com-positions indicating that they represent the first post-differentiation crust-building magmatism [1, 2]. Sam-ples of Mg-suite materials were found at every Apollo landing site except 11 and all exhibit geochemical characteristics indicating the involvement of KREEP in their petrogenesis [3-5]. This has led to the sugges-tion that the KREEP reservoir under the nearside was responsible for Mg-suite magmatism [e.g., 5, 6]. The lack of readily identifiable Mg-suite rocks in meteoritic regolith breccias sourced from outside the Procellarum KREEP Terrane (PKT) seemingly supports this interpretation.
