月球科研重大突破！

Core Insights - The research team has made a significant breakthrough in lunar science by discovering micron-sized hematite (α-Fe2O3) and magnetite (γ-Fe2O3) crystals in samples returned by the Chang'e 6 mission, indicating a new lunar oxidation reaction mechanism [1][3][5] - This discovery provides empirical evidence for the impact origin of magnetic anomalies surrounding the South Pole-Aitken Basin, enhancing the understanding of the Moon's evolutionary history [3][5] Group 1 - The formation of hematite is closely related to large impact events in the Moon's history, which create a high oxygen fugacity gas environment, leading to the oxidation of iron and the formation of micron-sized crystalline hematite particles [5] - The intermediate products of this reaction include magnetic minerals, which may serve as the mineral carriers for the magnetic anomalies observed in the South Pole-Aitken Basin [5][7] - The South Pole-Aitken Basin, where the Chang'e 6 mission landed, is the largest and oldest known impact basin on rocky bodies in the solar system, providing a unique setting for exploring special geological processes [7] Group 2 - The findings have been published in the international journal "Science Advances," which will serve as an important scientific basis for future lunar research [3] - The successful collection of lunar samples from the South Pole-Aitken Basin by the Chang'e 6 mission in 2024 laid the groundwork for this groundbreaking discovery [7]
