The lunar Mg\u2010suite is part of this sample collection and ubiquitously have geochemical characteristics indicating the involvement of KREEP in their petrogenesis and seemed to be linked to the Procellarum KREEP Terrain. However, it is unclear if KREEP is necessary for Mg\u2010suite magmatism, or whether Mg\u2010suite magmatism was a global event that occurred without significant KREEP contribution and thus, Mg\u2010suite rocks outside of the PKT region may exist without containing a significant KREEP\u2010signature. Here, we investigate lunar meteorite NWA 10401, an anorthositic troctolitic breccia with a granulitic texture. NWA 10401 shares many characteristics of Apollo Mg\u2010suite rocks: both its bulk rock composition and alumina content, as well as its mineralogy and mineral chemistry, are more consistent with typical Apollo Mg\u2010suite rocks, rather than ferroan anorthosites. In addition, olivine\u2010spinel equilibria calculations indicate that NWA 10401 is consistent with being derived from a common parent to the Apollo Mg\u2010suite troctolites. However, despite these many shared characteristics, NWA 10401 is strongly depleted in REE, starkly separating it from the typical Apollo Mg\u2010suite of the PKT. This indicates that NWA 10401 (and pairs) could represent a Mg\u2010suite component outside the PKT, and thus, KREEP\u2010poor Mg\u2010suite magmatism may have been a global phenomenon on the Moon.”<\/p>\n","protected":false},"excerpt":{"rendered":"
