摘要

The effects of Arabia-Eurasia collision are recorded in faults, basins, and exhumed metamorphic massifs across eastern and central Anatolia. These faults and basins also preserve evidence of major changes in deformation and associated sedimentary processes along major suture zones including the Inner Tauride suture where it lies along the southern (Ecemi?) segment of the Central Anatolian fault zone. Stratigraphic and structural data from the Ecemi? fault zone, adjacent NE Uluk??la basin, and metamorphic dome (Ni?de Massif) record two fundamentally different stages in the Cenozoic tectonic evolution of this part of central Anatolia. The Paleogene sedimentary and volcanic strata of the NE Uluk??la basin (Ecemi? corridor) were deposited in marginal marine to marine environments on the exhuming Ni?de Massif and east of it. A late Eocene–Oligocene transpressional stage of deformation involved oblique northward thrusting of older Paleogene strata onto the eastern Ni?de Massif and of the eastern massif onto the rest of the massif, reburying the entire massif to 10 km depth and accompanied by left-lateral motion on the Ecemi? fault zone. A profound change in the tectonic setting at the end of the Oligocene produced widespread transtensional deformation across the area west of the Ecemi? fault zone in the Miocene. In this stage, the Ecemi? fault zone had at least 25 km of left-lateral offset. Before and during this faulting episode, the central Tauride Mountains to the east became a source of sediments that were deposited in small Miocene transtensional basins formed on the Eocene–Oligocene thrust belt between the Ecemi? fault zone and the Ni?de Massif. Normal faults compatible with SW-directed extension cut across the Ni?de Massif and are associated with a second (Miocene) re-exhumation of the Massif. Geochronology and thermochronology indicate that the transtensional stage started at ca. 23–22 Ma, coeval with large and diverse geological and tectonic changes across Anatolia.
