Figure 1
The phase diagram of MgSiO3 based on previous studies (Presnall & Gasparik, 1990; Yusa et al., 1993; Angel & Hugh-Jones, 1994). HT-CEn crystals were confirmed in all the samples recovered, formed by quenching from the pressures and temperatures indicated by circles in the figure. The predicted quenching route from HP-CEn is shown by the shaded arrow. |
