The Suhut graben is an 8 - 11- km- wide, 24- km- long, N - S- trending, active extensional structure located on the southern shoulder of the Aksehir- Afyon graben, near the apex of the outer Isparta Angle. The Suhut graben developed on a pre- Upper Pliocene rock assemblage comprising pre- Jurassic metamorphic rocks, Jurassic - Lower Cretaceous platform carbonates, the Lower Miocene - Middle Pliocene Afyon stratovolcanic complex and a fluvio-lacustrine volcano- sedimentary sequence.

Çukurören-Çobanlar (Afyon) arasındaki deprem kaynaklarının (aktif fayların) belirlenmesi Koçyiğit, Ali; Deveci, Şule(2007) The Şuhut graben is an about 8-11 km wide, 24 km long, N-S-trending and actively growing extensional neotectonic structure located on the southern shoulder of the major AkşehirAfyon graben near the apex of outer Isparta Angle. The Şuhut graben developed on a pre-Upper Pliocene basement rock assemblage composed mostly of pre-Jurassic metamorphic rocks and Jurassic–Lower Cretaceous platform carbonates overlain with an angular unconformity by the Afyon strato-volcanic complex to its fluvio-lacustrine sedimenta...
The Character and displacement of Adıyaman fault (southeast anatolia): evidence from subsurface data Durukan, Bayram Alper; Bozkurt, Erdin; Department of Geological Engineering (2019) Structural interpretation of five 2D seismic sections acquired by TPAO is carried out in the Adıyaman region of Southeast Anatolia. The sections are geological calibrated with stratigraphic logs of five boreholes. This study has resulted in the discovery of a previously undefined fault, herein named as Şambayat Fault. The fault is a NW-SEtrending structure that parallels the Bozova Fault and comprises several parallel fault segments. The structural maps of Cretaceous Sayındere and Karababa formations are al...
Major Late Cretaceous Mass Flows in Central Turkey Recording the Disruption of the Mesozoic Continental Margin Okay, Aral; Altıner, Demir; Kylander-Clark, Andrew R. C. (American Geophysical Union (AGU), 2019-03-01) The newly recognized Upper Cretaceous (similar to 87Ma) olistostrome belt in central Turkey west of Ankara extends for more than 112 km subparallel to the Izmir-Ankara suture with a width of 10 km. The Alacaatl Olistostromes are stratigraphically underlain by a Triassic basement, and are up to 2 km thick. Over 80% of the blocks in the olistostromes consist of pelagic limestones, which reach up to 300 m in size; other blocks include basalt, chert, serpentinite, tuff, and sandstone. The limestone blocks are J...
Extensional neotectonic regime through the NE edge of the outer Isparta Angle, SW Turkey: New field and seismic data Özacar, Atilla Arda (2003-01-01) The Akşehir-Afyon Graben (AAG) is a 4-20-km-wide, 130-km-long NW-trending depression that separates central Anatolia in the NE and the Isparta Angle (IA) in the SW. Its southwestern margin-bounding fault determines the northeast edge of the outer IA that was previously interpreted as a compressional neotectonic structure, whereas our field evidence and recent seismic data substantiated that it is an oblique-slip normal fault characterising an extensional neotectonic regime. The AAG has an episodic and asymm...
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...
