A team of Chinese scientists studying lunar soil samples brought to Earth by the Chang’e-5 automatic interplanetary station found signs of volcanic lava eruptions in them. This was announced by the National Space Science Center under the Chinese Academy of Sciences.
It is noted that experts have found geological evidence of the presence of several layers of volcanic lava. Uranium, thorium and potassium were also found in soil samples.
Chinese scientists have estimated the thickness of basalt rocks in the landing area of Chang’e-5. It turned out that there were at least four magmatic eruptions with an average thickness of 230 meters, 70 meters, 4 meters and 36 meters. It was also found that the rate of basalt eruption in the area increased significantly about two billion years ago.
Recall that on December 16, 2020, the Chang’e-5 apparatus delivered soil samples to Earth – 1731 grams – from the surface of the Moon in the region of the Ocean of Storms. China became the first country in the last 44 years (after the Soviet “Luna-24” in 1976) to implement a project to transport geological samples from the surface of the Moon, and the third country after the USA and the USSR, which managed to carry out such a task.
