Neogene volcanic rocks and granitoid plutons are among the most important geological components of western Turkey. Although they are voluminous north of the Gediz Graben, they are very scarce to the south, where volcanic rocks occur as isolated small exposures in a small number of localities. The Kiraz Basin of the Kucuk Menderes Graben is a key locality, in which Tertiary volcanic rocks crop out at three locations. These rocks have been chemically analysed and dated ((39)Ar-(40)Ar whole rock and biotite analyses) in order to understand their tectonic setting of emplacement and its relation to the wider structure of western Anatolia. Whole rock and biotite (39)Ar-(40)Ar ages vary between 13.9 +/- 0.2 Ma and 14.6 +/- 0.2 Ma.


Age and kinematics of the Burdur Basin: Inferences for the existence of the Fethiye Burdur Fault Zone in SW Anatolia (Turkey)

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...
Origin of NE-trending basins in western Turkey
Bozkurt, Erdin (Elsevier BV, 2003-03-01)
The origin of NE-trending basins and their relation to the E-W-trending grabens in western Turkey have been the subject of long lasting debate. The stratigraphical and structural aspects of the basin fill in the E-W Gediz Graben and in the NE-trending Gordes, Demirci, Selendi and Usak-Gure basins located immediately to the north of the graben are reassessed here. The Gediz Graben is characterized by two contrasting sedimentary packages that are separated by an angular unconformity. These are: (1) a folded M...
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...
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...
