TL;DR: High-Pressure Phases is a main entry in the 外星矿物知识引擎 database.
2025 research proved that high-pressure mineral phases (ringwoodite, wadsleyite) can form and remain intact in weakly shocked meteorites. These minerals normally exist deep in planetary mantles. Their presence in meteorites provides a window into deep planetary interiors and impact physics.
Formula
Mg₂SiO₄ (polymorphs)
Crystal System
Cubic / Orthorhombic
Occurrence
Found in shocked meteorites; mantle transition zone minerals; discovered in weakly shocked meteorites (2025)
Significance
Proves high-pressure phases can form and remain in weakly shocked meteorites; relevant for understanding planetary interiors and impact processes
