记者从国家航天局获悉，近日，我国科研团队通过分析嫦娥六号采回的月背南极-艾特肯盆地月球 样品，取得月球科学研究重大突破——首次发现大型撞击事件成因的微米级赤铁矿（α-Fe2O3）和磁赤 铁矿（γ-Fe2O3）晶体，揭示了全新的月球氧化反应机制，为环绕南极-艾肯盆地磁异常的撞击成因提供 了样品实证。 该研究成果由山东大学行星科学团队联合中国科学院地球化学研究所、云南大学科研人员共同完 成，得到国家航天局月球样品（编号：CE6C0300YJFM00301）的支持，在嫦娥六号月球样品中发现了 赤铁矿和磁赤铁矿矿物，并联用微区电子显微谱学、电子能量损失谱技术、拉曼光谱技术，确认了月球 原生赤铁矿颗粒的晶格结构以及独特的产状特征。成果已发表在国际综合性期刊Science Advances，将 为后续月球科学研究提供重要科学依据，深化对月球演化历史的认知。 自人类登月以来，月球被认为整体还原，极度缺少氧化作用的关键证据，特别是赤铁矿等高价态铁 氧化物。研究提出，赤铁矿的形成可能与月球历史上的大型撞击事件密切相关。大型撞击形成瞬时高氧 逸度气相环境的同时，铁元素在高氧逸度环境中被氧化，使陨硫铁发生了脱硫反应，经气相沉积过程 ...

央视网消息：11月16日，国家航天局、山东大学、中国科学院联合发布消息，我国科研团队通过分析嫦娥六号采回的月球样品，取 得月球科学研究重大突破——首次发现大型撞击事件成因的微米级赤铁矿和磁赤铁矿晶体。揭示了全新的月球氧化反应机制，为环 绕南极-艾特肯盆地磁异常的撞击成因提供了样品实证。 据介绍，该研究成果由山东大学行星科学团队联合中国科学院地球化学研究所、云南大学科研人员共同完成。科研团队围绕从国家 航天局申请到的3000毫克嫦娥六号月球样品，开展了系统、深入、细致的研究，发现了赋存三价铁离子的赤铁矿和磁赤铁矿矿物。 山东大学空间科学与技术学院副院长凌宗成介绍，他们在数千条月壤光谱数据当中找到了赤铁矿的线索，利用电镜微区分析等手段 对于矿物的晶体结构和矿物种类进行了识别。最终在嫦娥六号月壤样品当中，首次发现了赤铁矿和磁赤铁矿两种矿物，这是月球氧 化作用研究的重大科学突破。 月球表面由于没有大气保护且缺乏水，整体处于还原环境，几乎不可能存在强氧化物，就好比一块不会生锈的铁，几乎不可能形 成"铁锈"。而科研团队发现的赤铁矿属于高价态的三价铁氧化物，是月球存在强氧化作用的关键证据。 研究团队介绍，赤铁矿的形成可能与 ...

Core Viewpoint - The announcement from Mount Gibson Iron Limited (MGI) regarding a significant rockfall incident at the Koolan Iron Ore mine has led to the suspension of mining activities in the affected area, impacting iron ore supply to the company [1][2]. Group 1: Incident Details - A major rockfall occurred on October 16, 2025, at the eastern side of the main pit of the Koolan Iron Ore mine [1]. - MGI has determined that remediation and resumption of mining operations in the affected area are not feasible due to safety risks and the limited remaining mining life of the Koolan area, which was expected to conclude around September 2026 [2]. Group 2: Operational Impact - Mining activities at the Koolan area have been suspended, although processing of available ore stockpiles will continue to meet scheduled shipments [2]. - MGI has notified that some shipments originally planned for the fourth quarter of 2025 will be delayed due to the incident [2]. Group 3: Company Response - The company maintains that all major business operations are running normally as of the announcement date [2]. - MGI is currently in discussions with Koolan regarding iron ore supply and is assessing the overall impact of the incident on its business [2].

Core Viewpoint - The significant rockfall incident at Koolan Island has led to the suspension of mining activities, impacting the iron ore supply to the company, which relies on Koolan as a major supplier [1][2]. Group 1: Incident Details - On October 16, 2025, a major rockfall occurred in the main pit area of Koolan Island, affecting operations [1]. - Koolan is a key supplier of iron ore, bound by a long-term supply agreement to provide 80% of its available total production to the company until the mine permanently ceases operations [1]. Group 2: Operational Impact - Due to safety concerns regarding the stability of the affected area, MGI has deemed it unfeasible to resume mining operations at Koolan [2]. - Mining activities at Koolan have been suspended, although processing of available ore stockpiles will continue to meet scheduled shipments [2]. - The company has notified the group of delays in shipments originally scheduled for the fourth quarter of 2025 [2]. Group 3: Future Considerations - The remaining mining life of the Koolan operation was limited, with plans to conclude by September 2026 prior to the incident [2]. - The company is currently in discussions with Koolan regarding iron ore supply and assessing the overall impact of the incident on its business [2].
