P–T diagrams for the sample SW9. The SW9 bulk is apatite corrected and ignores TiO₂ and MnO (see text). Models from Domino software (de Capitani and Petrakakis 2010). a Green field for Pg present assemblages. Blue points 1 and 2 are at P–T conditions for the Grt Grs₃₀Prp₈ from b. Dashed violett line marks a linear gradient of 9.5 °C/km. b Grt composition isopleths for Grs and Prp with two intersections (blue points) for the measured Grt mantle and rim Grs₃₀Prp₈ in the sample SW9
