Abstract: The Tauride fold and thrust belt formed during ~N-S convergence between African and Eurasian platessince Cretaceous time. This movement led to the development of a complex morpho-tectonic structure, so-called‘Isparta Angle’ during the early stage of the Neogene time. In Miocene time, the western and central Tauridesand the inner part of the Isparta Angle became overlain by marine sedimentary basins which are characterized byclastics and carbonates. Aksu Basin which is determined as study area is one of these marine basins and is locatedin the center of the Isparta Angle. Therefore, Aksu Basin contains the geological records of the crustal deformationoccurred during the Neogene period.The sedimentary infill of the Aksu Basin is mainly characterized by marine clastics with more than 1 km thickfrom the Middle Miocene to Pliocene. The pre-Pliocene basin infill was subjected to intense deformation. Sedimentarysequence of the Aksu Basin starts with Burdigalian-Langhian Oymapınar Limestone which unconformably overliesthe basement unit. The lithostratigraphy in the north is different from that of the south of the basin. The youngestMiocene unit in the north of the basin is the Tortonian aged and the units deposited between Tortonian and Pleistoceneis missing in the sequence. On the other hand, the sequence is more complete in the south of the basin. In additionto lithostratigraphic features, the structural elements which are forming the Aksu Basin are also carried out duringthis study. These are the Aksu and Kapıkaya thrusts. Field observations and results obtained from the kinematicmeasurements along the key structural zones show that Aksu Basin developed through four different tectonic phases.While the first phase is ~E-W extensional phase which is related to opening of the basin, the second phase is ~N-Scompressional Lycian phase. The third phase is ~E-W compressional (Aksu) phase, which is the most prominentphase in the basin. N-S extensional phase is determined as the fourth and the last tectonic phase.Under the light of whole data, presence of the E-W shortening which is active between Serravalian and EarlyPliocene in the center of the Isparta Angle is interesting given the plate tectonic setting driven by N-S convergenceof the Africa and Eurasia. The seismic tomography images of the mantle below the Isparta Angle indicates that thereare two separate slab segments (Cyprus and Antalya slabs). Therefore, an important impact of the Antalya slabshould be expected in the Mio-Pliocene and even modern evolution of the Isparta Angle and the uplift of the Taurides.
