A joint research team from the Institute of Geochemistry of the Chinese Academy of Sciences (IGCAS) and Shandong University has for the first time identified crystalline hematite (α-Fe2O3) and maghemite (γ-Fe2O3) formed by a major impact event in lunar soil samples retrieved by China’s Chang’e-6 mission from the South Pole–Aitken (SPA) Basin. This finding, published in Science Advances on November 14, provides direct sample-based evidence of highly oxidized materials on the lunar surface.
