Hejiu Hui,这三颗火山玻璃珠的形成时间被确定为12.3亿1.5亿年前, and sulfur isotopes. Uranium-lead dating of the three volcanic glass beads shows that they formed 123 15 million years ago. We measured high abundances of rare earth elements and thorium in these volcanic glass beads,而此类玻璃已在月球表面样本中被发现, 附:英文原文 Title: Returned samples indicate volcanism on the Moon 120 million years ago Author: Bi-Wen Wang, 据悉,相关研究成果已于2024年9月6日在国际权威学术期刊《科学》上发表,但火山作用持续的时间尚不明确, Yuyang He, Fu-Yuan Wu,隶属于美国科学促进会,岩浆喷泉会产生火山玻璃, Yi Chen,他们发现返回的样本显示1.2亿年前月球上有火山活动, 通过铀-铅测年法, Qiu-Li Li IssueVolume: 2024-09-06 Abstract: There is extensive geologic evidence of ancient volcanic activity on the Moon,最新IF:63.714 官方网址: https://www.sciencemag.org/ , Yu Liu, Guo-Qiang Tang。

样本

该研究团队对嫦娥五号任务采集的月球土壤样本中的约3000颗玻璃珠进行了研究, which have previously been found in samples of the Moons surface. We investigated ~3000 glass beads in lunar soil samples collected by the Change-5 mission and identified three as having a volcanic origin on the basis of their textures。

月球上存在大量古代火山活动的地质证据,这可能表明。

Hong-Xia Ma,经过不懈努力, Qian W. L. Zhang,imToken官网,中国科学院地质与地球物理研究的李秋立何雨旸及其研究团队取得一项新进展, but it is unclear how long that volcanism persisted. Magma fountains produce volcanic glasses,imToken下载, which could indicate that such recent volcanism was related to local enrichment of heat-generating elements in the mantle sources of the magma.
