In this study, it was aimed to show the Plio-Quaternary terrestrial and marine sediments deposited in the coasts of Southwestern Anatolia and the tectonic and global origin of those units that reveal the sea level changes by using integrated stratigraphic and structural geologic data. This stıdy comprise the results of the first data conducted in Datça, Bodrum, Söke and Germencik areas are selected in the scope of this study. In this presentation, first observations from Datça area will be discussed. The NW-SE trending Datça graben which is a depression field located in the central part of the Datça Peninsula, is 12 km long and 5 km wide filled with terrestrial and marine sediments and is bounded in the north by the Kızlan fault and by series of normal faults oriented in N-S direction. For the kinematic analyses, 859 silickenline data are collected from 31 observation points, which are located in the northern side of the graben, and they are analyzed according to Angelier Paleostress Inversion technique. The first observations show that the northern part of the basin is experienced almost N-S extension. Faults with strike slip components are also observed at some locations resulted by strike slip fault tectonism of the region. Magnetostratigraphy technique is used in order to date the Plio-Pleistocene sedimentary rocks in the Datca graben. In the scope of this work, magnetostratigraphic samples were collected from the sites which includes sedimentary rocks deposited in Plio-Pleistocene time interval. At three different stratigraphic section, 344 sample were collected from 102 stratigraphic levels. The paleomagnetic analysis of the samples are conducted in Fort Hofddjik Paleomagnetism Laboratory, University of Utrecht. The magnetostratigraphic section is compared with the Global Polarity Time scale (GPTS) as a result of the analysis. In addition to the available age data, structural data and Anisotropy of Magnetic Susceptibility (AMS) results that show the amount and orientation of the deformation will be compared. This research is supported by TUBITAK (The Scientific and Technological Research Council of Turkey) –Grant Number: 117R012.

Identification of morphometric properties of basins located on western part of NAFZ Sarp, Gülcan; Toprak, Vedat; Düzgün, H. Şebnem; Department of Geodetic and Geographical Information Technologies (2012) This study aims to investigate tectonic activity levels and development stages of the tectonic and hydrologic basin areas located on western part of the main trace of the North Anatolian Fault Zone (NAFZ) using quantitative measurement techniques. The basins investigated are Bolu, Yeniçağa, Dörtdivan, Çerkes, Ilgaz and Tosya. The methodology includes application of six morphometric indices (Basin Shape, Hypsometric curve and Hypsometric Integral, Sinuosity of Mountain Fronts, Stream Length Gradient Index, V...
Dating the Sea of Marmara sediments by a uniform mixing model Gokmen, A; Yildiz, M; Erten, HN; Salihoglu, I (1996-01-01) The sedimentation rates and Pb-210 fluxes on sediment surfaces were measured in the north, northwestern and southwestern parts of the Sea of Marmara. Each core had varying thickness of constant Pb-210 activity regions followed by a decreasing part with sediment depth. The sedimentation rates of the samples collected from the Bosporus and the Dardanelles could not be analysed due to the homogenization of activity in the strong currents of these straits. A uniform mixing model is proposed for the simultaneous...
A geochemical approach to Neogene-Quaternary volcanic activity of western Anatolia: An example of episodic bimodal volcanism within the Selendi Basin, Turkey Ersoy, Y.; Helvaci, C.; Sozbilir, H.; ERKÜL, FUAT; Bozkurt, Erdin (2008-09-30) New radiometric age and geochemical data are presented from the late Cenozoic volcanic activity in the Selendi Basin of western Anatolia. Stratigraphical and age data show that the volcanism occurred in four distinct stages from the early Miocene to Quaternary. The first early Miocene stage includes two volcanic units with contrasting compositions: the Egreltidag volcanic unit and the Kuzayir lamproite. These volcanic units interfinger with the sedimentary rocks of the early Miocene Hacibekir Group. The Egr...
A sequence stratigraphic approach to the depositional history analysis of the upper eocene sedimentary succession, northwest of the thrace basin, Turkey Sünnetçioğlu, Mehmet Akif; Altıner, Demir; Department of Geological Engineering (2008) This study investigates the depositional history of the Late Eocene sedimentary record in the northwest of the Thrace Basin in a sequence stratigraphic approach and estimates the contribution of regional tectonics, basin physiography and eustasy. Late Eocene sedimentary succession was analyzed in two third-order sequences based on two major data sets; seismic reflection and well data sets. Depositional Sequence-1, represented by progradational stacking patterns, comprises the coarse-grained “Hamitabat” turb...
First Balanced Cross Section Across the Taurides Fold-Thrust Belt: Geological Constraints on the Subduction History of the Antalya Slab in Southern Anatolia McPhee, Peter J.; Altıner, Demir; van Hinsbergen, Douwe J. J. (2018-10-01) Eastern Mediterranean subduction accommodated Africa-Eurasia convergence since Mesozoic time and produced multiple subducted slab fragments in the mantle below Anatolia. These included the north dipping Cyprus and ENE-dipping Antalya slabs, which are currently separated by an upper mantle slab gap. Segmentation of these slabs, and associated mantle flow, may have contributed to <8 Ma uplift of the Central Anatolian Plateau. The western Central Taurides fold-thrust belt in southern Turkey is in the upper pla...
