Pattern of normal faulting in the Gediz Graben, SW Turkey

Ciftci, N. Bozkurt
Bozkurt, Erdin
Hanging-wall deformation of the fault systems controlling the southern margin of the Gediz Graben were investigated separately within the Plio-Quaternary and Neogene (predominantly Miocene) deposits of the graben fill. Fault styles observed in both packages share many similarities in terms of geometry and comprise conjugate fault sets that show clustering of strike orientations predominantly around WNW-ESE but also SW-NE and NW-SE directions. The main difference between the two units is observable in terms of fault dips and rake of the slickenside lineations measured on the exposed fault planes. Both measurements show a uni-modal distribution for the Plio-Quaternary deposits but a tri-modal distribution for the Neogene deposits. This variation is probably related to the geometrical modification of the older faults by the process of domino style back-rotation in the hanging wall of higher order faults.


High-altitude Plio-Quaternary fluvial deposits and their implication on the tilt of a horst, western Anatolia, Turkey
Süzen, Mehmet Lütfi; Rojay, B (Elsevier BV, 2006-03-01)
This study investigates the origin and regional tectonic implications of high-altitude Plio (?)-Quaternary fluvial deposits developed over the Bozdak horst which is an important structural element within the horst-graben system of western Anatolia, Turkey. A total of 23 deposits occur near the modem drainage divide comprising fluvial to occasionally lacustrine deposits. The deposits are all elongated in N-S direction with a width/length ratio of 1/10. The largest of them is of 13 km in length with a maximum...
Zircon ages from the Beypazari granitoid pluton (north central Turkey): tectonic implications
Speciale, Pamela A.; Catlos, Elizabeth J.; Yildiz, G. Okan; Shin, Timothy A.; Black, Karen N. (Informa UK Limited, 2012-09-01)
The Beypazari granitoid is emplaced in a Late Cretaceous volcanic arc in north central Turkey and provides evidence for processes that occurred during the closure of the Neo-Tethys Ocean. Zircons from its northern granodiorite and quartz monzonite exposure are dated in rock thin section and display characteristic igneous zoning in cathodoluminescence (CL). Its oldest Late Cretaceous ages (95.4 +/- 4.2-91.3 +/- 6.5 Ma, U-238/Pb-206, +/- 1 sigma) time early crystallization from rising melts, but inspection of...
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...
Age and kinematics of the Burdur Basin: Inferences for the existence of the Fethiye Burdur Fault Zone in SW Anatolia (Turkey)
ÖZKAPTAN, MURAT; Kaymakcı, Nuretdin; Langereis, Cor G.; Gulyuz, Erhan; Özacar, Atilla Arda; UZEL, BORA; SÖZBİLİR, HASAN (Elsevier BV, 2018-10-02)
The Burdur Basin is a late Miocene to Pliocene fluvio-lacustrine basin in SW Anatolia. It is developed within the postulated Fethiye-Burdur Fault Zone, which was argued to be a sinistral strike-slip fault zone developed in response to propagation of the Pliny-Strabo STEP fault into SW Anatolia (Turkey). In order to assess the presence and tectonic characteristics of the fault zone, we conducted a paleomagnetic study in the Burdur basin that involved rock magnetic experiments, Anisotropy of Magnetic Suscepti...
Shallow and deep-seated regolith slides on deforested slopes in Canakkale, NW Turkey
Ekinci, Yunus Levent; Turkes, Murat; DEMİRCİ, ALPER; ERGİNAL, AHMET EVREN (Elsevier BV, 2013-11-01)
This study deals with the stripping of regolith on a steep slope by surface wash and shallow landslides and a deep-seated landslide at a lower slope that took place on 17 February 2003 at the village of Mazilik, east of Canakkale, Turkey. Soil loss and shallow slides dominate on the deforested steep slopes in the study area and occur preferentially along slope-parallel sub-horizontal joint planes with clay coatings, particularly oxyhydroxides that are rich in Fe but poor in Mn as a result of weathering unde...
