The Denizli graben-horst system (DGHS) is located at the eastern-southeastern converging tips of three well-identified major grabens, the Gediz, the Kucuk Menderes and the Buyuk Menderes grabens, in the west Anatolian extensional province. It forms a structural link between these grabens and the other three NE-NW-trending grabens-the Civril, the Acigol and the Burdur grabens-compri sing the western limb of the Isparta Angle. Therefore, the DGHS has a critical role in the evolutionary history of continental extension and its eastward continuation in southwestern Turkey, including western Anatolia, west-central Anatolia, and the Isparta Angle. The DGHS is a 7-28-km wide, 62-km long, actively growing and very young rift developed upon metamorphic rocks of both the Menderes Massif and the Lycian nappes, and their Oligocene-Lower Miocene cover sequence. It consists of one incipient major graben, one modem major graben, two sub-grabens and two intervening sub-horsts evolved on the four palaeotectonic blocks. Therefore, the DGHS displays different trends along its length, namely, NW, E-W, NE and again E-W.

The Arkot Dag Melange in Arac area, central Turkey: Evidence of its origin within the geodynamic evolution of the Intra-Pontide suture zone Goncuoglu, M. Cemal; Marroni, Michele; Pandolfi, Luca; Eller, Alessandro; Ottria, Giuseppe; Catanzariti, Rita; TEKİN, UĞUR KAĞAN; Sayıt, Kaan (Elsevier BV, 2014-05-01) In northern Turkey, the Intra-Pontide suture zone is represented by an east-west trending belt of deformed and/or metamorphic units located at the boundary between the Istanbul-Zonguldak terrane to the north and the Sakarya terrane to the south. These units can be regarded as issued from the Intra-Pontide domain, whose geodynamic history is still a matter of debate. Along the Akpinar-Arac-Bayramoren geotraverse, located in central Turkey, an ophiolite-bearing melange known as the Arkot Dag Melange, is well-...
The relationship between Kestel Polje system and the Antalya Tufa Plateau: Their morphotectonic evolution in Isparta Angle, Antalya-Turkey DOĞAN, UĞUR; Kocyigit, Ali; Yeilyurt, Serdar (Elsevier BV, 2019-06-01) This paper focuses on the relation between two significant geomorphic features of the western Taurides: the Antalya Tufa Plateau and the structural Kestel polje system; revealing morphotectonic records of the formation and evolution of karst hydrology between the two features. Data were obtained by detailed mapping of faults, rocks, and geomorphic features. The evolutionary history of the area begins with a nearly E-W-trending drainage system which flowed on the erosional surfaces formed during late Langhia...
Kinematic and thermal evolution of the Haymana Basin, a fore-arc to foreland basin in Central Anatolia (Turkey) Gülyüz, Erhan; Özkaptan, Murat; Kaymakcı, Nuretdin; Persano, Cristina; Stuart, Finlay M. (Elsevier BV, 2019-09-05) Gondwana (Tauride/kirsehir blocks) and Eurasia (Pontides) derived continental blocks delimit the Haymana basin, central Turkey, to the south and the north, respectively. The boundaries of these blocks define the IzmirAnkara-Erzincan and Intra-Tauride Suture zones which are straddled by a number of Late Cretaceous to Oligocene marine to continental basins. The Haymana Basin is located at the junction of the IAESZ and ITSZ and comprises Upper Cretaceous to Middle Eocene basin infill deposited in response to t...
Suşehri basin: an active fault-wedge basin on the North Anatolian Fault Zone, Turkey Koçyiǧit, A. (Elsevier BV, 1989-10) The Suşehri section of the North Anatolian Fault Zone (NAFZ) is dominated by an active fault-wedge basin. Its recent configuration is a Quaternary strike-slip depression superimposed on a larger, fault-controlled fluvial to lacustrine setting inherited from the Pliocene. In and around the Suşehri fault-wedge basin, the NAFZ is characterized by the North Anatolian master fault (NAMF) or principal displacement zone (PDZ) and four second-order fault sets, namely the Kelkit, Akçaaǧil, Beydeǧirmeni and Ekenek fa...
A new intracontinental transcurrent structure: the Central Anatolian Fault Zone, Turkey Kocyigit, A; Beyhan, A (Elsevier BV, 1998-01-30) Recent neotectonic studies, including remote-sensing, aerial photographs, geological field mapping on various scales and measured stratigraphic section substantiate the existence of a large sinistral intracontinental transcurrent structure, which we call the Central Anatolian Fault Zone (CAFZ). This is an approximately 730-km-long, 2-km- to 80-km-wide, NE-trending, active sinistral strike-slip fault zone that cuts across the Anatolian plateau between Duzyayla in the northeast and Anamur County in the southw...
