Here we show that micrometeorite impact-induced charge disproportionation of iron could have produced the large amounts of ferric iron (average Fe3+\/\u2211Fe\u2009>\u20090.4) in agglutinate melts returned by China\u2019s Chang\u2019e-5 mission. The charge disproportionation reaction synchronously generated nanophase metallic iron (npFe0), and quantitative analyses of iron valence indicate that it is a dominant pathway for formation of npFe0 within the lunar agglutinate glass. The discovery of the charge disproportionation reaction in the agglutinates suggests that much more Fe3+ could be present on the Moon than previously thought, and that its abundance is progressively increasing with micrometeoroid impacts.”<\/p>\n","protected":false},"excerpt":{"rendered":"
