Abstract

On the Dilek Peninsula, western part of the Menderes Massif, relies of HP metamorphism under epidote-blueschist facies conditions were recognised in metavolcanic and marry interlayers of the Mesozoic cover series. Ar-40/Ar-39 determinations of phengites revealed Tertiary ages (40 Ma) for the subduction-related high-pressure metamorphism (470 degrees C, min. 10 kbar). Lithostratigraphic correlation allows to suggest a similar age for the HP metamorphism on Samos.
