• The rocks of the Yunquera Unit (Alpujárride Complex) record two stages, at least, of recrystallization at different P-T conditions defined by the mineral associations: a) Grt + Pl + Ms + St + Ky + Qtz, and b) Grt + Pl + Sill + Qtz ± Bt. The metamorphic peak for the first stage has been estimated at ca. 1200-1300 MPa and 560-695 ºC through conventional thermobarometry. The second mineral association was equilibrated at 600 MPa and 700 ºC. These data support the existence of an initial high-pressure metamorphic stage followed by a pressure drop and final cooling during the Alpine exhumation of the Unit.
