Volcanism on the Moon - Wikipedia
Volcanism on the Moon is represented by the presence of volcanoes, pyroclastic deposits and vast lava plains on the lunar surface. The volcanoes are typically in the form of small domes and cones that form large volcanic complexes and isolated edifices.
Returned samples indicate volcanism on the Moon 120 million
2024年9月5日 · Dating of lunar volcanic basalt samples, returned to Earth by the Apollo and Luna missions or delivered to Earth as lunar meteorites, has shown that basaltic volcanism on the Moon occurred as early as 4.4 billion years ago (Ga) …
How young is volcanism on the Moon? | Science - AAAS
2024年9月5日 · Analyses of rocks and soils delivered by the Apollo and Luna missions have established that the Moon is ancient, dry, and depleted of volatile elements. Studies also have indicated that early in its history, the Moon was covered with molten rock. This magma ocean eventually cooled and produced a compositionally diverse surface crust (1).
Recent volcanic eruptions on the moon - Science | AAAS
2014年10月12日 · The moon, thought to be cold and dead, is still alive and kicking—barely. Scientists have found evidence for dozens of burps of volcanic activity, all within the past 100 million years—a mere blip on the geologic timescale. And they think that future eruptions are likely—although probably not within a human lifetime.
Surges in volcanic activity on the Moon about two billion
2023年6月22日 · The history of mare volcanism critically informs the thermal evolution of the Moon. However, young volcanic eruptions are poorly constrained by remote observations and limited samples,...
Volcanism on the Moon - ScienceDirect
2015年1月1日 · The Moon has been volcanically active for most of its 4600 million-year history. Lunar volcanism is dominated by the production of basalt, erupted as flood lavas from fissure vents at very high rates of effusion, resulting in the creation of the visible maria, the dark, smooth lowlands of the Moon.
Recent Volcanoes on the Moon? - UC Davis
2024年9月4日 · New results from China’s Chang’e 5 lunar samples returned to Earth provide evidence for active volcanoes on the Moon as recently as 120 million years ago. Previously, scientists had thought that any activity with magma (molten rock) rising to the Moon’s surface ended billions of years ago.
Young Volcanoes on the Moon - NASA Science
2014年11月23日 · There's nothing odd about volcanoes on the Moon, per se. Much of the Moon's ancient surface is covered with hardened lava. The main features of the "Man in the Moon," in fact, are old basaltic flows deposited billions of years ago …
NASA Mission Finds Widespread Evidence of Young Lunar Volcanism
2022年11月22日 · NASA’s Lunar Reconnaissance Orbiter (LRO) has provided researchers strong evidence the moon’s volcanic activity slowed gradually instead of stopping abruptly a billion years ago. Scores of distinctive rock deposits observed by LRO are estimated to be less than 100 million years old.
Three glass beads bring into question the timeline of lunar volcanism
2024年10月7日 · Radiometric dating of material returned from the Moon suggests there was active volcanism on the satellite 120 million years ago, nearly 2 billion years more recent than previous estimates.
