A team led by Academician He Hongping from the Chinese Academy of Sciences has made a groundbreaking discovery in lunar soil samples retrieved by the Chang'e-5 mission. For the first time, they observed chromite nanocrystals growing outward from the surface of olivine in a mushroom-like formation. Utilizing advanced in-situ focused ion beam sample preparation and high-resolution transmission electron microscopy techniques, the research team delved into this intricate micro-nano mineralogical phenomenon. Their findings revealed that, under extreme non-equilibrium conditions, impurity ions within the original phase can catalyze the growth of new mineral phases at heterogeneous interfaces. This novel mechanism not only expands the realm of non-classical growth mechanisms but also holds significant implications for the mineral composition and element distribution of lunar regolith. It serves as a valuable resource for crystal growth research under extreme conditions.
