There was active volcanic activity on the Moon even when dinosaurs lived on Earth, he claimed On Radio Information László Kiss, Director General of the Research Institute of Astronomy and Earth Sciences of the HUN-REN Galactic Research Network.
Soil and rock samples brought to Earth by China's Chang'e-5 lunar probe from the far side of the Moon were recently analysed. About 44 years later, the spacecraft delivered a lunar soil sample to Earth, in a total amount of 1,731 grams. The samples revealed active volcanic activity on the moon during the age of dinosaurs, and it did not end billions of years ago as scientists previously thought.
Small pieces of glass hide secrets
Chinese scientists examined the composition and structure of about 3,000 small spherical grains (pellets) with diameters between 20 and 400 microns found in the samples.
As Laszlo Kiss reported for Radio, these globules resemble glass, and were formed either as a result of a small celestial body colliding with the surface of the Moon, or they flew from within the Moon to the surface during ancient volcanic eruptions. Explosions. A substance that becomes liquid at high temperatures either way During its flight, as a result of sudden cooling, it turned into glassy grains, that is, a solid substance with an amorphous or perhaps crystalline structure was formed.
The Director-General explained that out of 3,000 small spherical pellets, the Chinese found three pellets, and after examining them, they concluded that the vitrification process that created the small pellets occurred 123 million years ago, when dinosaurs were already living on Earth.
According to the scientist, this is surprising because until now we thought that the last volcanic eruption on the Moon ended no later than three billion years ago.
In comparison, there could have been active volcanic activity on the Moon even 120 million years ago.
