“…A Late Paleozoic to Late Cretaceous sedimentary cover, deposited on top of late Proterozoic (Cadomian) basement, shows a progressive deepening of depositional environments ending with a Late Paleocene-Early Eocene olistostrome (Ö nay 1949;Dürr 1975;Caglayan et al 1980;Ö zkürt and Koçyigit 1983;Sengör et al 1984;Konak et al 1987;Ö zer 1998;Ö zer et al 2001).

now Institut des Sciences de la Terre d'OrléansInternational audienceThe Aegean region is a concentrate of the main geodynamic processes that shaped the Mediterranean region: oceanic and continental subduction, mountain building, high-pressure and low-temperature metamorphism, backarc extension, post-orogenic collapse, metamorphic core complexes, gneiss domes are the ingredients of a complex evolution that started at the end of the Cretaceous with the closure of the Tethyan ocean along the Vardar suture zone. Using available plate kinematic, geophysical, petrological and structural data, we present a synthetic tectonic map of the whole region encompassing the Balkans, Western Turkey, the Aegean Sea, the Hellenic Arc, the Mediterranean Ridge and continental Greece and we build a lithospheric-scale N-S cross-section from Crete to the Rhodope massif. We then describe the tectonic evolution of this cross-section with a series of reconstructions from ~70 Ma to the Present. We follow on the hypothesis that a single subduction has been active throughout most of the Mesozoic and the entire Cenozoic, and we show that the geological record is compatible with this hypothesis. The reconstructions show that continental subduction (Apulian and Pelagonian continental blocks) did not induce slab break-off in this case. Using this evolution, we discuss the mechanisms leading to the exhumation of metamorphic rocks and the subsequent formation of extensional metamorphic domes in the backarc region during slab retreat. The tectonic histories of the two regions showing large-scale extension, the Rhodope and the Cyclades are then compared. The respective contributions to slab retreat, post-orogenic extension and lower crust partial melting of changes in kinematic boundary conditions and in nature of subducting material, from continental to oceanic, are discussed

“…14), kink folds are well observed in the cherty levels of the Gömce formation. The Gömce formation yields no fossils; however, we correlated it with the Kõzõlag AE aç formation cropping out in the southern Menderes Massif owing to its lithological resemblance (Dürr 1975;Þag AE layan et al 1980;Konak et al 1987;Özer 1998). …”

“…Öztürk (1981) interpreted it as Palaeozoic, whereas Konak (1993) thought it might be Jurassic±Cretaceous. However, new observations on the age of schists (Erdog AE an and Güngör 1992) and presence of the metabasic volcanic intercalations in equivalent units in the western Menderes Massif suggest an upper Mesozoic age, probably Cretaceous (Erdog AE an and Güngör 1992;Özer 1993, 1998. The Bükrüce formation is conformably overlain by the Gömce formation.…”

“…Although the detailed kinematic evolution of the massif is controversial (e.g. Bozkurt and Park 1997;Collins and Robertson 1998;Hetzel et al 1998), much evidence indicates that the entire southern Menderes Massif was overthrust by the Lycian thrust sheets during the Tertiary (Graciansky 1972;Okay 1989;Collins and Robertson 1997, 1998, 1999Ring et al 1999).…”

The stratigraphy of the uppermost levels of the Menderes Massif is controversial and within its details lie vital constraints to the tectonic evolution of south-western Turkey. Our primary study was carried out in four reference areas along the southern and eastern Menderes Massif. These areas lie in the upper part of the Menderes metamorphic cover and have a clear stratigraphic relationship and contain datable fossils. The first one, in the Akbük±Milas area, is located south-east of Bafa Lake where the Milas, then Kõzõlag AE aç and Kazõklõ formations are well exposed. There, the Milas formation grades upwards into the Kõzõlag AE aç formation. The contact between the Kõzõla-g AE aç and the overlying Kazõklõ formation is not clearly seen but is interpreted as an unconformity. The Milas and Kõzõlag AE aç formations are also found north of Mug AE la, in the region of Yatag AE an and Kavaklõdere. In these areas, the Milas formation consists of schists and conformably overlying platform-type, emery and rudist-bearing marbles. Rudists form the main palaeontological data from which a Santonian±Campa-nian age is indicated. The Kõzõlag AE aç formation is characterized by reddish±greyish pelagic marbles with marly-pelitic interlayers and coarsening up debris flow deposits. Pelagic marbles within the formation contain planktonic foraminifera and nanoplankton of late Campanian to late Maastrichtian age. The Kazõklõ formation is of flysch type and includes carbonate blocks.

“…Above the basal conglomerates, the`marble envelope' consists of the following rock types: (1) Upper Triassic±Liassic marbles intercalated with schists and metavolcanics; (2) a Jurassic±Lower Cretaceous thick, massive marble unit with metabauxite lenses (Konak et al 1987); (3) Upper Cretaceous rudist-bearing marbles intercalated locally with thin mica schists (Dürr 1975;Konak et al 1987;Özer 1998). The thickness of the platform-type marbles reaches up to 2 km (Dürr et al 1978;Güngör 1998).…”

The Menderes Massif covers large areas in western Turkey. The better understanding of its tectono-metamorphic history would provide insight for the Alpine evolution of western Turkey and the entire eastern Mediterranean region. This paper summarizes the available literature on the metamorphic rocks of western Turkey and that of the Menderes Massif with special reference and emphasis to the papers presented in the special issue.
