Magneto usually involves major scientific issues such as paleomagnetic fields and extraterrestrial life, so it has attracted much attention from scholars in the field of planetary science. The extreme reduction environment on the moon's surface makes the iron elements in lunar soil mainly include divalent iron ions and zero-valent iron. In the Apollo era, only a very small number of trivalent iron ions and their minerals were directly detected.
Recently, the Research team of the Institute of Geochemistry of the Chinese Academy of Sciences conducted in-depth and detailed in-situ micro-region analysis on the sulfide particles in the lunar soil powder on the Chang'e-5 surface, confirming for the first time the existence of submicron-scale magnetite in the lunar soil. Research evidence shows that sulfides on the moon's surface will undergo a complex gas-liquid reaction during the impact, allowing FeO dissolved into the sulfide to generate submicron-scale magnetite and elemental metal iron through euthanization reaction. This research result was recently published in the international academic journal Nature-Communication. The discovery and confirmation of submicron-scale magnetites in the cause of impact of
impact provides direct evidence for the academic speculation that native magnetites may be widely present in lunar soil, and can also provide experimental verification and theoretical support for the explanation of major scientific issues such as magnetic anomalies on the surface of the moon.
