Palaeomagnetic data in combination with palaeostress data and anisotropy of magnetic susceptibility orientations are utilized to develop a tectonic evolutionary model for the Early Tertiary part of the Omega(omega)-shaped Cankiri Basin (Turkey). The results reveal clockwise rotations in the northeast and anticlockwise rotations in the west and southeastern corner of the basin. The magnetic inclinations indicate a northward drift of the Cankiri Basin and support an indentation model for the Kirsehir Block. It is proposed that the Omega-shape of the Cankiri Basin was the result of indentation of the Kirsehir Block into the Sakarya Continent during northwards migration accompanying closure of Neotethys. It appears that the indentation started prior to Eocene and ended before Middle Miocene times.

GIS based geothermal potential assessment for Western Anatolia Tüfekçi, Nesrin; Süzen, Mehmet Lütfi; Department of Geological Engineering (2006) This thesis aims to predict the probable undiscovered geothermal systems through investigation of spatial relation between geothermal occurrences and its surrounding geological phenomenon in Western Anatolia. In this context, four different public data, which are epicenter map, lineament map, Bouger gravity anomaly and magnetic anomaly maps, are utilized. In order to extract the necessary information for each map layer the raw public data is converted to a synthetic data which are directly used in the analy...
Morphometric analysis of active tectonic imprints at the junction of Büyük Menderes and Bozdoğan grabens, Western Anatolia Usta, Sultan Gamze; Süzen, Mehmet Lütfi; Özacar, Atilla Arda; Department of Geological Engineering (2015) Analysis of the basin asymmetry and morphometric indices is an effective methodology to detect surface signatures of active tectonic processes and to understand the differential uplift. Thus, basins controlled by active faults with different orientations provide a unique opportunity to evaluate fault controlled tilting. In this study, a morphometric analysis is conducted by means of the analytical capabilities of numerical computing and GIS software for an area characterized by orthogonal normal faults and ...
Structural evolution of the Gediz Graben, SW Turkey: temporal and spatial variation of the graben basin Ciftci, N. B.; Bozkurt, Erdin (Wiley, 2010-12-01) The structural evolution of the Miocene to Recent Gediz Graben is intimately related to the evolution of its southern margin. This margin is shaped by a time-transgressive, composite structure that possesses flat-ramp geometry with three separate dip domains: a low-angle shallow segment; a steeper middle segment; and a low-angle deeper segment. This geometry was probably produced by one of two mechanisms, which operated perpendicular to the general trend of the graben, resulting in gradual back-rotation fol...
Geoarchaelogical investigation of central anatolian caravanserais using gis Ertepınar Kaymakcı, Pnar; Toprak, Vedat; Department of Geological Engineering (2005) This study comprises analysis of geological, geomorphological constraints that played role in the site selection of caravanserais. In order to do this, 15 caravanserais located along a route from Nevşehir-Aksaray-Konya to Beyşehir were used. The data used in the study include a caravanserai database, lithological maps, and digital elevation model of the area. GIS analyses performed in the study are proximity, visibility, and probability distribution (PDA). The first step is the generation of the ancient tra...
Post-paleogene stress distribution in the Bartın-Ulus-Safranbolu Basins, Western pontides, Turkey Bengü, Emre; Rojay, Fuat Bora; Department of Geological Engineering (2017) The thesis addresses the post-Paleogene tectonic evolution of the Bartın-UlusSafranbolu basins in Western Pontides. The study area is bounded by Black Sea from north, Sünnice Massif from west, Kargı Massif from east, and by Cretaceous ophiolitic mélanges and the North Anatolian Fault from south. These basins are separated from each other by the two main faults, namely, Bartın and Karabük faults. Four structural domains are defined, based on lithostratigraphic differences and bounding major faults, to figure...
