科学与健康｜月球也会“生锈”？嫦娥六号月背样品中首次发现晶质赤铁矿

Core Insights - The research team from China has discovered that lunar soil and rocks can exhibit signs of "rust," specifically through the identification of micro-sized hematite and magnetite crystals from samples collected by the Chang'e 6 mission [2][4][5] - This finding reveals a new lunar oxidation reaction mechanism and provides empirical evidence for the impact-related origins of magnetic anomalies in the South Pole-Aitken Basin [2][5] Group 1: Research Findings - The study indicates that the formation of lunar hematite is closely linked to large impact events in the Moon's history, which create a transient high oxygen fugacity gas phase environment [4][5] - The presence of hematite and other strong oxidizing substances on the lunar surface under ultra-reducing conditions has been confirmed for the first time, shedding light on the Moon's redox state and the causes of magnetic anomalies [5][7] Group 2: Mission Background - The Chang'e 6 mission successfully retrieved samples from the South Pole-Aitken Basin, the largest and oldest known impact basin on rocky bodies in the solar system, providing a unique context for exploring special geological processes [7] - The research was conducted by a collaborative team from Shandong University, the Chinese Academy of Sciences, and Yunnan University, with support from the National Space Administration of China, and the findings have been published in the international journal "Science Advances" [7]
