The 3D-architecture of the Malatya Basin was studied using remote sensing, seismic interpretation, and palaeostress analysis in the context of the Malatya-Ovacik fault zone. The results indicate that the Ovacik and Malatya fault zones are not different segments of a single 'so called' Malatya-Ovacik fault zone; rather, they are two different fault zones that have operated independently. In addition, the Ovacik fault zone is delimited in the west by the Malatya fault zone, which extends farther north from the point of supposed junction. Maximum individual deflection of streams along the Ovacik fault zone is about 9.3 km, and summation of all stream deflections along different segments of the Ovacik fault zone indicates that sinistral displacement of the Ovacik fault zone has been not more than 20 km following development of the drainage system in the region.

Late Miocene transcurrent tectonics in NW Turkey: evidence from palaeomagnetism and 40Ar–39Ar dating of alkaline volcanic rocks
KAYMAKCI, N.; Kaymakcı, Nuretdin; LANGEREIS, C.; SPELL, T. L.; GURER, O. F.; ZANETTI, K. A. (Cambridge University Press (CUP), 2007-2-9)
<jats:p>A number of intra-continental alkaline volcanic sequences in NW Turkey were emplaced along localized extensional gaps within dextral strike-slip fault zones prior to the initiation of the North Anatolian Fault Zone. This study presents new palaeomagnetic and <jats:sup>40</jats:sup>Ar–<jats:sup>39</jats:sup>Ar geochronological results from the lava flows of NW Turkey as a contribution towards understanding the Neogene–Quaternary tectonic evolution of the region and possible roles of block rotations i...
Late quaternary seismic stratigraphy and active faults of the Gulf of Izmit (NE Marmara Sea)
OKYAR, Mahmut; Pinar, Ali; Tezcan, Devrim; Kamaci, Zueheyr (2008-06-01)
The Upper Quaternary seismic stratigraphy and active faults of the Gulf of Izmit were investigated by means of high-resolution shallow seismic profiling data in the source region of 1999 Izmit earthquake. High-resolution seismic reflection data correlated with borehole data indicate that the stratigraphy of Izmit Bay consists of three distinct depositional sequences formed in response to middle Pleistocene-Holocene sea-level changes. Reflector R, separating the pre-Holocene sequences (1 and 2) from the Holo...
Fault-based probabilistic seismic hazard assessment of the eastern Makran subduction and the Chaman transform fault, Pakistan: Emphasis on the source characterization of megathrust
Shah, Syed Tanvir; Özacar, Atilla Arda; Gülerce, Zeynep (Elsevier BV, 2021-01-01)
Seismic source characterization (SSC) for probabilistic seismic hazard assessment (PSHA) in regions characterized by subduction megathrust involves a considerable ambiguity. Lack of detailed geologic, seismic, and geodetic data increases the uncertainties. The enigma is enhanced in regions where thin-skinned accretionary prism faults are part of active deformation. In this study, a planar SSC model for seismically active eastern Makran subduction zone, its associated accretionary prism faults and Chaman tra...
Kinematic and structural development of the Çankiri Basin Central Anatolia Turkey a paleostress inversion study
Kaymakcı, Nuretdin; Paul M, Vandijk (2003-03-01)
Three different deformation phases have been recognized in the southern part of the Cankin Basin from (1) the major structures and (2) through using paleostress inversion techniques for fault slip data. The deformation phases recognized from the paleostress data are correlated with those recognized from the major structures and dated accordingly. The first phase occurred in the Late Paleocene to pre-Burdigalian and is characterized by an oblique sigma(2) and NNE-SSW to NE-SW trending subhorizontal sigma(1) ...
