Morphological analyses in Hattusha (Boğazkale-Turkey)

Dündar, Pınar
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 where the city wall deviates from the topographic divide resulting in a shorter path and addition of certain areas to the city. The volume of the city wall between Lion and King’s gates is estimated to be 613966 m3 and covers an area of 130682 m2. Capacity of the eastern and southern ponds is estimated 15400 m3 and 22160 m3, respectively. Two potential dam sites are suggested outside the city with a total drainage basin of 0.2713 km2. For the visibility analysis performed inside the city, no relation is found between the visibility and the elevation of points.


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...
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...
Micropalentological analysis and sequence stratigraphy through upper tournaisian substage in Aladağ unit (Central Taurides, Turkey)
Dinç, Aksel Tuğba; Altıner, Demir; Department of Geological Engineering (2009)
The purpose of this study is to investigate the Upper Tournaisian substage within the Carboniferous carbonate deposits of the Aladağ Unit in the Hadim region (Central Taurides) based on foraminiferal diversity and to study the meter scale cyclicity in order to explain the sequence stratigraphic evolution of the carbonate succession. In this study, a 27.01 m thick stratigraphic section consisting of limestones and shales was measured and 89 samples, collected along this section, were analyzed. Micropaleontol...
Mineralogical and geochemical properties of messinian gypsum occurence in Polatlı Sazılar region, Ankara
Çakmak, Hayriye; Köksal, Fatma; Department of Geological Engineering (2008)
The objective of this study is to understand the petrographical, mineralogical and geochemical characteristics of Messinian (Upper Miocene) gypsum occurence in Polatlı Sazılar region, Ankara and to determine the impurities associated with gypsum. Moreover, it is aimed to interpret the usability of this raw material with impurities in plaster and plasterboard production based on industrial standards. Based on petrographical study, the first variety of gypsum which have different physical properties is white ...
Geology and petrology of Beypazarı-Oymaağaç granitoids /
İpekgil, Ceren; Lünel, Taylan; Department of Geological Engineering (2005)
The purpose of this study is to investigate the origin, source characteristics, evolution petrogenesis and emplacement mechanisms of Beypazari-Oymaagaç granitoids. These granitoids are intruded into a metamorphic basement and nonconformably overlain by Neogene clastic rocks. Field work, petrographical and geochemical studies are carried out to determine the petrologic features and tectonic setting of the granitoid body. The Beypazari-Oymaagaç pluton is a composite pluton with its host batholith, enclaves, a...
