Brillouin Scattering Observations of Elastic Behavior Across the Post‐Stishovite Transition Under Deviatoric Stress in Polycrystalline Al‐Bearing Stishovite

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 5, May 2026.
Abstract Stishovite (SiO2), a key phase in subducted mid‐ocean ridge basalt (MORB), undergoes a ferroelastic transition to a CaCl2‐type structure, potentially explaining localized shear wave velocity (VS) anomalies in the shallow to mid‐lower mantle. However, the phase boundary determining this transition remains debated.
