Abstract: The article focuses on the identification and analysis of a seifertite-bearing norite clast (EGP15-G32) found in the lunar soil returned by China’s Chang’E-6 (CE6) mission from the Apollo Basin within the South Pole–Aitken Basin. Through integrated petrographic, geochemical, and shock metamorphism studies, the clast is characterized as a highly shocked Mg-suite norite, distinct from local mare basalts, with shock pressures estimated at 24–40 GPa indicated by the coexistence of maskelynite and seifertite (a high-pressure silica polymorph). Combining mineralogical data with impact modeling and regional geology, the study constrains the Chaffee S crater as the likely source of this exotic ejecta, providing insights into material transport and crustal diversity on the lunar farside. This approach demonstrates the utility of high-pressure mineralogy in tracing the provenance of non-mare components in lunar samples. [Extracted from the article]
