10月6日，在中华民族传统佳节中秋节之际，国家航天局和国家原子能机构联合发布嫦娥六号月球背面 样品研究最新成果。中国科学家首次基于嫦娥六号月球背面样品研究发现，月球背面月幔相比月球正面 更"冷"，这一发现进一步深化了人类对月球"二分性"现象的认识，为月球正面与月球背面的月幔温度差 异提供了岩石学与地球化学等科学依据，为月球演化和"二分性"特征研究提供了关键科学数据。 该研究结果由中核集团核工业北京地质研究院、北京大学、山东大学合作完成，已刊发于国际顶级学术 期刊《自然·地球科学》（Nature Geoscience）官网。 来源：央视新闻客户端 月球就像一本记录太阳系历史的书籍，而月幔是这本书中的"核心章节"。月幔位于月壳之下，是月球体 积最大的组成部分，月球古老的火山活动正是由月幔物质上涌形成的。因此，月幔等月球内部特征对于 月球演化研究至关重要。 在研究中，科学家利用可"侦探"的多种手段，对我国嫦娥六号从月球背面带回的玄武岩样品进行了精细 分析。这些样本的化学成分如同一个"黑匣子"，记录了其形成时的深部温度压力等信息。科学家通过对 月壤玄武岩样品中典型单斜辉石、斜长石等矿物的成分分析，运用"单斜辉石单矿物 ...

传统观点认为，月球晚期火山活动可能与富水或放射性元素有关，但嫦娥五号、六号样品推翻了这 一假说。基于对嫦娥六号两类玄武岩的对比，研究团队提出了一个新的热动力机制：随着月球冷却，其 岩石圈不断增厚，深部岩浆难以直接喷出，只能滞留在月幔浅部辉石岩层的底部。这些"被卡住的"岩浆 可向上传导热量，从而触发浅部月幔部分熔融，导致火山喷发。 论文第一作者、中国科学院广州地球化学所副研究员汪程远介绍，研究还发现，月球正面和背面的 晚期火山岩石化学特征存在差异，表明月球正面和背面的月幔组成可能不同，这为理解月球的不对称演 化提供了新线索。 （原载于《科技日报》 2025-08-25 第01版） 月球"晚年"仍存在火山活动的奥秘揭开。通过系统研究嫦娥六号月球样品，来自中国科学院广州地 球化学研究所等单位的研究团队，成功揭示月球"晚年"火山活动的热驱动机制。相关研究成果8月23日 在线发表于《科学进展》杂志。 长期以来，科学家普遍认为月球在30亿年前就已"休眠"，但嫦娥五号和六号任务带回的样品显示， 月球在20亿至28亿年前仍有火山喷发。到底是什么提供了热量，让月球在衰老期还保持"活力"？ 在这项研究中，研究团队在嫦娥六号样品中 ...
