The main foliation (S2 ) represents an evolution of the S1 to slightly higher temperature and lower pressure, but it is still developed in blueschist facies conditions. Post-S2 deformations include restricted development of spaced C’ shear bands, tight and straight D3 folds and a later gentle subhorizontal crenulation formed in greenschists facies conditions. Garnet-phengite thermometry and GRIPS and GASP barometry calculations, using micro-inclusion compositions, indicate peak conditions around P=19-22 Kbar and T=430-500 ºC. The same calculations using the S2 fabric minerals yield approximate values of P=16-19 Kbar and T=440-515 ºC.spajournal article2173-6545https://sociedadgeologica.org/publicaciones/geogaceta/geogaceta-43-2007/https://sge.usal.es/archivos/geogacetas/Geo43/Art01.pdfopen access552.4(460)Variscan BeltAllochthonous ComplexesMalpica-Tui UnitBlueschists faciesthermobarometryPetrología2506.13 Petrología Ignea y Metamórfica
