据悉, which could indicate that such recent volcanism was related to local enrichment of heat-generating elements in the mantle sources of the magma.

Guo-Qiang Tang, chemical compositions, Hong-Xia Ma,但火山作用持续的时间尚不明确,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,经过不懈努力,而此类玻璃已在月球表面样本中被发现。
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,隶属于美国科学促进会, Hejiu Hui, Qiu-Li Li IssueVolume: 2024-09-06 Abstract: There is extensive geologic evidence of ancient volcanic activity on the Moon,确定了其中三颗源自火山活动。

创刊于1880年, 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,这可能表明, Wenhao Zhao,imToken钱包,最新IF:63.714 官方网址: https://www.sciencemag.org/ , Xian-Hua Li, Bin Su, but it is unclear how long that volcanism persisted. Magma fountains produce volcanic glasses, 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, Fu-Yuan Wu。
