Machine learning determines the Mg2SiO4 P-T phase diagram
Siyu Zhou, Daohong Liu, Chuanyu Zhang +3
Phase transitions among Mg2SiO4 and its high-pressure polymorphs (wadsleyite and ringwoodite) are central to mantle dynamics and deep-mantle material cycling. However, the location…

Absence of dehydration due to superionic transition at Earth's core-mantle boundary
Yu He, Wei Zhang, Qingyang Hu +9
The properties and stability of hydrous phases are key to unraveling the mysteries of the water cycle in Earth's interior. Under the deep lower mantle conditions, hydrous phases tr…
