Abstract: All research on neotectonics in Turkey accepts Western Anatolia as a distinct, separate region in which theneotectonic period began in Upper Oligocene, according to some researchers, and in Upper Miocene according toothers, and has continued up to the present day. The region expanded in a north-south direction during this processgrabens were formed, generally with an east-west orientation. In this interpretation, the normal faults causing a north-south oriented extension are proposed to have detachmentfault characteristics. As observed in field studies, fold and strike-slip faults developed during this period but thesedimentary basin geometry and dimensions cannot be explained by a simple graben system. There are outliers interms of the chemistry of volcanism in outcropping areas. Explanations for these inconsistencies have yet to be foundand those based on time-space-causal relationships related to evolution in the neotectonic period do not go beyondabstract modelling. In this presentation, a different model is suggested with the aim of solving controversies in the models proposed todate. The recommended method is based on the neotectonic evolution explanatory principle of revealing the currentdeformation form in a region in order to understand its neotectonics, and then working backwards from today. Currently, the tectonic region defined as Western Anatolia encompasses an area between the northwest-southeastoriented Bursa-Eskişehir-Afyon Fault Zone and the northeast-southwest oriented Muğla-Afyon Fault Zone in the east,extending in a sideways V shape towards the west. Moving toward the west, the region is separated in intraplateblocks due to the lithological differences, paleotectonic structures and volcanism, etc. present in the region. Thedifferent movement velocities of these separate blocks cause deformation in the region. Significant factors affectingthese motions are the dimensions, velocity and direction of the blocks. With the varying motion of the blocks, normal,reverse and strike-slip faults along with extensional fractures occur along the block boundaries. In this model,different movements may be observed in different locations on the same fault plane. Again, there are parallel, coevalstructures found in the region, although they move in different directions. On the whole, block movements progresstoward the west-southwest of the region. Extensions occurring between blocks occasionally form graben geometry. According to this proposed model, the east-west oriented grabens currently observed in Western Anatolia areconcluded not to be products of north-south oriented extensions. Currently, the greatest extension is on the easternboundaries of the V-shaped block. Intensive thermal manifestations are observed north of this boundary in the KulaVolcanics and to the south in the Pamukkale region. The 10-km long fracture caused by the 1995 Dinar Earthquakeand the aseismic deformation motion at Sarıgöl both have extensional fracture characteristics.Paleomagnetism, crustal thickness, GPS data and the fault-plane solutions of earthquakes in the region supportthis model. This proposed kinematic model is thought to have been in operation about 3-4 million years before thepresent.
