Summary of P–T estimates in sample JB-19-33. For inverse thermobarometry, reported P and T are average of several measurements. Reported uncertainties of ± 50 °C and ± 0.5 GPa are conservative estimates taking into account composition variation and internal calibration uncertainty (Nimis and Grütter, 2010).
Résumé des estimations P–T sur l’échantillon JB-19-33. Pour la thermobarométrie inverse, les valeurs de P et T reportées, sont des moyennes obtenues à partir de plusieurs mesures dans chaque domaine. Les incertitudes rapportées de ± 50 °C et ± 0.5 GPa sont des estimations conservatrices prenant en compte les variations de composition et les incertitudes internes des différents thermobaromètres (Nimis et Grütter, 2010).
