The purpose of this study is to investigate the effect of rock types and morphologic classes on the locations of underground cities existing in Cappadocia. To achieve this purpose four databases are created that contain related information of underground cities, present settlements, rock types and morphologic classes. Four main analyses are carried out using the data created fort the study. These analyses are: 1) Distance analysis to determine the distances between underground cities and present settlements, 2) Density analysis to inspect the areas where the underground cities are concentrated, 3) Distribution analysis to explore the spatial distribution of underground cities within the rock types and morphologic classes, and 4) Neighbourhood analysis to examine whether the underground cities within rock types and morphologic classes are located along or far inside the marginsof the polygons. The conclusions reached after the analyses are as follows: 1) The mean distance between two underground cities is about 4 km. 2) The mean distance between an underground city and the nearest present settlement is about 700 m. 3) Underground cities are concentrated in Derinkuyu-Nevsehir-Özkonak belt. Present settlements, on the other hand, are concentrated along Aksaray-Ortaköy-Hacibektas. 4) For the underground cities, pyroclastic dominant Neogene sequences are preferred whereas all other units are avoided. 5) In terms of morphology, the class defined as أmesaؤ is strongly preferred for underground cities. 6) Neither lithology nor morphology played a role in the site selection for present settlements. 7) Both for rock types and morphologic classes the underground cities are located along margins of the polygons.

Geoarchaeological investigations in Zeugma, Turkey Karaca, Ceren; Toprak, Vedat; Department of Geological Engineering (2008) The purpose of this study is to investigate the geological and morphological features around ancient city of Zeugma. To achieve this, a geological map of Zeugma excavation site is prepared; an aerial photographic survey and morphological analyses are conducted on a broader area. Additionally, the biggest ancient quarry in the study area is investigated. In the close vicinity of Zeugma, four lithologies which are, from bottom to top, clayey limestone, thick bedded limestone, chalky limestone and cherty limes...
Geology and joint analysis of the Derinkuyu and Kaymaklı underground cities of Cappadocia, Turkey Mutlu, Mehmet Özgür; Toprak, Vedat; Department of Geological Engineering (2008) This thesis attempts to detect the ignimbrite units in which the underground cities were carved and the relationship between the joints in these ignimbrites and the walls of underground cities. Orientation of rooms, directions of walls and joints are input data used in the study. Two sites in Cappadocia (Derinkuyu and Kaymaklı) are selected to investigate the relationship. Measurements taken from 46 rooms of Derinkuyu and 64 rooms of Kaymaklı are analyzed for the room and joint directions, joint locations i...
Morphological analyses in Hattusha (Boğazkale-Turkey) Dündar, Pınar; Toprak, Vedat; Department of Geological Engineering (2009) The purpose of this study is to investigate the morphological properties of the ancient city Hattusha and its surroundings. To achieve this, the analyses are conducted on the digital topographical maps at 1/25000 and 1/1000 scales. Results of the analyses reveal that Hattusha is located over a north facing surface with slope values of 6 to 15 degrees within an elevation range of 1000 to 1250 m. All main building complexes are confined to a narrow slope interval of 2 to 15 degrees. Five regions are detected ...
Determination of the dynamic characteristics and local site conditions of the plio-quarternary sediments situated towards the north of Ankara through surface wave testing methods Eker, Arif Mert; Akgün, Haluk; Department of Geological Engineering (2009) The purpose of this study is to assess the engineering geological and geotechnical characteristics and to perform seismic hazard studies of the Upper Pliocene to Quaternary (Plio-Quaternary) deposits located towards the north of Ankara through surface wave testing methods. Based on a general engineering geological and seismic site characterization studies, site classification systems are assigned in seismic hazard assessments. The objective of the research is to determine the regional and local seismic soil...
Meter scale cycles in the eocene Çayraz Formation (Haymana Basin) and response of foraminifers to cyclicity Erbaş (Geyikçioğlu), Bedia; Altıner, Demir; Department of Geological Engineering (2008) The aim of this study is to investigate the nature of the meter-scale cycles in the Çayraz Formation of the Middle Eocene age and to study the response of foraminifera to the sedimentary cyclicity. In order to perform this study, two stratigraphic sections, which are 44,55 m and 25,95 m in thickness, were measured on a regularly bedded succession mainly composed of carbonates and siliciclastics in the Çayraz Formation of the Haymana Basin. In this study, detailed microfacies analyses were carried out in the...
