THE TECTONOSTRATIGRAPHIC FEATURES OF THE BELEMEDİK TECTONIC WINDOW AND ITS SURROUNDINGS

Abstract

The study area includes Belemedik and its vicinity located in the eastern part of Ecemiş Fault Zone which constitutes the boundary between Central and Eastern Taurides. The area generally presents Belemedik sequence belonging to Aladağ Unit, ophiolithic melange and ophiolithic rocks belonging to Bozkır Unit and Tertiary sediments overlying all these units. Within Belemedik sequence, Late Devonian aged Küçükali, Carboniferous aged Belemedik, Early Permian aged Sarıoluk, Late Permian aged Kızılgeriş and Yellice, Early Middle Triassic aged Katarası, Middle-Late Triassic aged Sarıyarma, Jurassic-Cretaceous aged Çamlık and Yavça Formations were differentiated. In the previous studies on the vicinity of Belemedik, it was suggested that an incomplete Mesozoic series overlaying the Palaeozoic core and as a result of the erosion of this cover, a tectonic window was exposed. However, in this study, it was demonstrated that a complete Mesozoic series of Early Triassic-Late Cretaceous age overlaying the Palaeozoic rocks in the vicinity of Belemedik are presented and hence a tectonic window does not exist in the vicinity of Belemedik. In addition, it was determined that Belemedik Sequence displayed similar features with the rock associations of Aladað Unit in terms of lithological properties and the ages of the units it comprises. In the region, at the bottom of the Bozkır Unit, which tectonically overlies the Belemedik Sequence, Late Senonian aged Kızılcadað Ophiolithic Melange and olistostrome are present. And, at the top of the Bozkır Unit, Late Cretaceous-aged Pozantı-Karsantı Ophiolithic Nappe is located. While the Pozantı-Ecemiş Corridor formed by Ecemiş Fault Zone is represented by Oligocene-Miocene aged units, the Adana Basin is represented by Paleocene-Late Miocene units.
