Arguin 002, the first whole-rock meteorite classified as a lunar norite, offers a unique opportunity to explore the genesis and timing of Mg-suite rocks. Here we investigated the petrology, mineralogy, geochemistry, and chronology of Arguin 002, revealing it to be an evolved, KREEP-free Mg-suite rock with chemical similarities to atypical Apollo-15 Fe-norites. It likely formed through plutonic magmatism originating from low-degree partial melting of a deep, KREEP-free mantle source and has a 207Pb\/206Pb age of 4341.5 \u00b1 9.3 Ma. The potential source of Arguin 002 is within the South Pole-Aitken basin, near the Chang\u2019e-6 landing site. These findings indicate that Mg-suite magmatism was a global and nearly synchronous event, potentially driven by rapid global mantle overturn.&#8221;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Zilong Wang, Wei Tian, Wei-RZ Wang, Tabb C.
