Recently, Du Wei team, a member of the Outstanding Innovation Center of the Chinese Academy of Sciences and the Institute of Geochemistry of the Chinese Academy of Sciences, found the high -voltage phase of the coexistence of silicon -based silicon in Chang'e 5, the Sai quartz and Solita.

It is understood that the impact effect is an important geological process for the mixed surface of the moon, and it is an important factor in controlling the formation and evolution of the moon soil. As an important recorder of the impact incident, high -pressure minerals are of great significance to the temperature of limited rocks' impact and the size of the anti -tangled impact pit. However, whether the moon returns a sample or the lunar meteorite, high -pressure mineral phase is rarely found, which limits the research of the impact process of the lunar table through the moon sample.

The Chinese scientific research team through the detailed study of Silicon, α-square quartz, and the morphological characteristics and distribution rules of silicon dioxide glass in the scientific research team to infer the formation mechanism of Symnaria and Syonaline for solid phase; collision The dynamic control of the process, as the sub -stability, appeared under lower pressure as a sub -stability, and the quarter of the quartz was transformed into Syonalians with the increase of temperature. Pressure and close -up and lowering the pressure. Through the simulation calculation of the temperature pressure conditions combined with the impact condition, it is speculated that the silicon dipping debris is likely to come from the AristArchus impact pit in the south of the Chang'e 5 sampling area.

This study was the first time that the Saiyin was found to be found in the lunar return sample, and provided important evidence that the viewing area of ​​Chang'e 5 in the sampling area of ​​the Chang'e -5 of the previous remote sensing data provided the view that there was a distant impact pit sputter.
