a Temperature evolution of Raman peak position (wavenumber) for the A1 mode near 465 cm−1 of free (red circles) and entrapped (black squares) quartz crystals (average error bar ±0.35 cm−1 and ±0.1 K). Above 1000 K the quartz inclusion triggered catastrophic embrittlement of the host garnet when approaching the temperature of the alpha-beta phase transition. b Expected pressure (P) evolution of a quartz inclusion calculated with almandine and pyrope hosts, plotted as lines (average error bar ±0.1 GPa and ±0.1 K). Solid symbols are the pressures calculated by applying the hydrostatic calibration to a linear fit of the free quartz data. The dashed line represents the alpha-beta phase transition boundary (redrawn and modified after ref. 14).
