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...
Discovery of Middle Permian volcanism in the Antalya Nappes, southern Turkey: tectonic significance and global meaning
Sahin, Nazif; Altıner, Demir; Ercengiz, M. Bulent (Informa UK Limited, 2012-09-01)
Detailed stratigraphic studies on the Middle-Upper Permian rocks of the Tahtalidag nappe (Antalya Nappes), largely exposed along the Guzelsu Corridor in central Taurides, have revealed the presence of basaltic volcanic rocks intercalated within the shallow-marine fossiliferous carbonate successions. Vitrophyric basaltic extrusions producing distinct pillows in the Kizilbag Formation severely dolomitized the associated carbonate rocks. The coeval Cukurkoy Formation, devoid of volcanic layers, is also exposed...
Defining the southern margin of Avalonia in the Pontides: Geochronological data from the Late Proterozoic and Ordovician granitoids from NW Turkey
Okay, Aral; Bozkurt, Erdin; Satir, Muharrem; YİĞİTBAŞ, ERDİNÇ; Crowley, Quentin G.; Shang, Cosmas K. (Elsevier BV, 2008-12-01)
We provide new isotopic data from the Pontides, which substantiate the presence of a Cadomian basement with latest Proterozoic granitoids but also show the existence of Ordovician intrusives. Before the opening of the Black Sea, the Pontides formed a Palaeozoic orogenic belt at the margin of the East European Platform (Baltica) in an analogous position to the Variscan terranes in the central Europe. The Pontides consist of three terranes: The Strandja terrane has a Variscan basement with Carboniferous and P...
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...
