Chinese researchers from the Institute of Geochemistry Chinese Academy of Sciences found for the first time fragments of seifertite and stishovite, minerals formed from silicon dioxide at high temperatures and pressures, in the CE-5 samples of lunar regolith. The sample also contained silicon dioxide and silica glass. This marks the first time for seifertite to be found in the samples from outside the Earth. Meteorite impact is an important geological process for the combination of materials on the lunar surface, which serves an important factor for controlling the formation and evolution of lunar soil.
