Textures Induced by the Coesite‐Stishovite Transition and Implications for the Visibility of the X‐Discontinuity

Abstract The coesite‐stishovite phase transition is considered the most plausible candidate to explain the X‐discontinuity observed at around 300 km depth in a variety of tectonic settings. Here, we investigate the microstructure in SiO2 across the coesite‐stishovite transition in uniaxial compressi...
