dc.description.abstractWe have analysed the thermobarometric equilibrium conditions reached during local equilibria among phengite + chlorite + quartz + water ± chloritoid ± garnet assemblages found in metapelites of the Ragua unit, the structurally-lowest tectonic unit outcropping in the Betics hinterland (southern Spain). Porphyroblast- deformation relationships show that lenticular domains preserved within the main foliation in the metapelites grew during a HP/LT prograde metamorphic event with thermal conditions of 320-450 °C and 12-14 kbar pressure. Hence, the Ragua unit subducted in a continental accretionary-wedge context, undergoing a tectonic evolution parallel to the one followed by the two other overlying Nevado-Filabride unitsen_US
