Popis:	Eclogites interlayered with amphibolites and migmatites occur in an upper unit (OjCn nappe) of the Alpujarride complex (Betic Cor- dilleras). Estimates of P-T conditions reveal a retrograde meta-morphic path from an edogitic stage at >15 kbar and c. 730 °C, to amphibolite-facies conditions at 5-8 kbar or less and c. 650 °C. The Ronda peridotites belonging to the uppermost Alpujarride nappe (Los Reales nappe) structurally overlie the eclogite-bearing unit. It is suggested that eclogitic metamorphism and overthrusting of the peridotites reflect dfierent stages of the same convergent episode.
