Compressional pathways of α-cristobalite, structure of cristobalite X-I, and towards the understanding of seifertite formation
In various shocked meteorites, low-pressure silica polymorph α-cristobalite is commonly found in close spatial relation with the densest known SiO(2) polymorph seifertite, which is stable above ∼80 GPa. We demonstrate that under hydrostatic pressure α-cristobalite remains untransformed up to at leas...
