New findings by researchers show that 1.97 billion years ago, lava was still on a single surface thanks to new rocks brought from China by the moon. Earth's moons have been moving. Bring to the ground. This mission was the first since the Soviet Luna 24 mission in 1976 to bring a sample of the moon. It was the latest volcanic activity on the moon, made possible by an international collaboration with researchers from China, Australia, Sweden and the United States.
Igneous rocks were predicted to be of this age, but it was not possible to verify the matter without having samples to study, and now the Chinese mission has opened a new scientific gateway. SHRIMP) was held at the Shrimp Center in Beijing. First the materials were sorted and then the researchers manually selected a few small pieces of basalt (volcanic rock) with a size of about 2 mm for study. These samples were then analyzed using laboratory methods based on experiments developed during the Apollo missions in the 1970s.

The process of determining the age of rocks is complex, but in principle, a focused beam of charged particles is used to expel the various phases of minerals from the samples and then examine them. Eventually, the researchers' efforts yielded 1.97 billion years, which was younger than previous basaltic lavas.

A New Scientific Secret
In the history of lunar evolution, many volcanic activity has taken place, forming large plates of basalt. These effects are known as lunar seawater and are known as dark spots on the moon's surface. Most volcanic activity occurred between 3 and 4 billion years ago, and planetary scientists have studied basalt samples collected during The Apollo and Luna missions, as well as lunar meteorites, have confirmed this. It is in the celestial body and the formation of molten material. For a mass the size of the moon, it was previously thought that this heat disappeared 2 billion years ago, long before these rocks.
So new findings have created a new scientific conundrum as to how a mass A small moon-like rock with a lifespan of 4.5 billion years can have enough heat 2.5 billion years after formation to continue volcanic eruptions.

While scientists have suggested that high concentrations of radioactive material on the moon could melt its internal rock material, the composition of the new samples shows that this factor did not play a role.
