What is Ubiquitous and progressively increasing ferric iron content on the lunar surfaces revealed by the Chang’e-5 sample about?
Although ferric iron indisputably exists on the highly reducing surface of the Moon, its formation mechanism and evolution are still under debate. Here we show that micrometeorite impact-induced charge disproportionation of iron could have produced the large amounts of ferric iron (average Fe 3+ /∑Fe > 0.4) in agglutinate melts returned by China's Chang'e-5 mission. The charge disproportionation reaction synchronously generated nanophase metallic iron (npFe 0 ), and quantitative analyses of iron valence indicate that it is a dominant pathway for formation of npFe 0 within the lunar agglutinate glass. The discovery of the charge disproportionation reaction in the agglutinates suggests that much more Fe 3+ could be present on the Moon than previously thought, and that its abundance is progressively increasing with micrometeoroid impacts.Iron is a critical element that records the oxygen potentials of solar system materials 1-3 . The lunar surface and interior are identified as highly reducing because Apollo samples mainly contained ferrous (Fe 2+ ) or metallic iron (Fe 0 ), and only small amounts of ferric iron ions (Fe 3+ ) ( 0.4) from charge disproportionation of iron during micro
