Abstract

The lowermost group of units of the Attic-Cycladic crystalline complex is formed by a stacked sequence of thrust sheets composed of a Permo-Mesozoic sequence of marbles, metapelites, acid and basic metavolcanites underlain by remnants of a pre-Alpidic crystalline basement. The complex underwent a high-pressure metamorphism in Eocene times and was affected by a Oligo-/Miocene medium-pressure overprint under greenschist to amphibolite fades conditions. The high-pressure assemblages, best preserved on the islands of Sifnos and Syros conform to the transition from the epidote-blueschist to the eclogite facies with temperatures of about 450-500 degrees C and pressures in the range between 12 and 20 kbar. The high-pressure event is inferred to be related to the northward directed subduction of the Apulian microplate beneath the Eurasian continent.
