Solved Mystery: The discovery of the ancient vent of the moon – science
A. South-Iteken Pole Basin, the largest and ancient influence on the moon was established 4.25 billion years ago. Comes the invention from the analysis of Lunar soil samples collected by Chinese mission Chang -6.
South-Iteken Pole Basin (Spa) on the hidden side of the moon This is a huge effect of about 2,500 km diameter. It is expected to emerge in the extreme period The asteroid bomb attackIt formed the planets of the solar system and moons in the first 500 million years after it was formed.
So far, The exact age of the vent is a secret, expectations that are very diverseIt makes it difficult to understand its importance in lunar and planetary history.
Chang -6 Mission Brought The first live models of spaInitializing the exact analysis.

A team led by Chen, Institute of Geology and Geophysics of the Academy of Sciences, 1,600 fragments of lunar clay were examined. Of these, they have been identified 20 fragments of noritis, a kind of mineral rockIt was formed from the effect that the span was created.
The use of advanced isotopic dating techniques in small zircon minerals found in these fragments, Scientists have identified two major impact events: one 4.25 billion years ago and one occurred 3.87 billion years ago.
The symptoms of old fragments indicate that they are crystallized in the different depths of a massive inscription that is produced by the effect of the span.
These results indicate significant progress in understanding the history of the moon. With the timeline and extension of craters on the lunar surface for 4.25 billion years, it serves as an important indication of calibration in the solar system..
In addition, the Discovery ensures that the global thermal event that has occurred between 4.35 and 4.33 billion is not related to spa formation.
New information Helps in re -designing the temporary line of the moon’s initial evolutionSubmission Important evidence of dynamic processes that shape the primitive solar system.
