Fig. 12. Equilibration P-T conditions for the pyroxenites and gabbroic rocks from two-pyroxene thermometry and the enstatite-in-cpx barometry (Putirka, 2008, 2018). Error bars are 1. Calculated temperatures are consistent with sub-solidus recrystallization. Equilibrium assemblage diagram in the NCKFMASH system is calculated for a model IAT bulk-rock geochemistry at H2O-saturated conditions (Escuder-Viruete and Pérez-Estaún, 2013). The black arrow indicates the P-T path followed during the cooling of the Rio Boba plutonic sequence.
