Compressional pathways of α-cristobalite, structure of cristobalite X-I, and towards the understanding of seifertite formation

The presence of α-seifertite and seiferite in shocked meteorites are used to determine shock pressures. Here, using high-pressure experiments, the authors find that the presence of α-cristobalite does not exclude high-pressure transformation and seifertite does not necessarily indicate high pressure...
