Geoarchaeological investigations in Zeugma, Turkey

Karaca, Ceren
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 limestone are identified. A major fault with a vertical throw of 80 m is mapped in the area. Geological survey reveals that the excavation site is located within the chalky limestone and the rock tombs are carved within the thick bedded limestone. In the aerial photographic survey, Fırat River is classified into 4 morphological classes which are river, island, flood plain and basement. The change among these classes is investigated between 1953 and 1992. The results reveal that there is no considerable variation in the position of the river channel and margins of flood plain within 39 years. The major change is observed in the islands that are built within the flood plain. Testing the elevation of Gaziantep and Fırat formations boundary using the relief map, investigating the visibility of selected points in the area, predicting the source area for the water supply, and evaluating the nature of the ancient route, constitute the morphological analysis carried out in this study. However, these analyses are not studied in detail and should be considered as the first attempts for more detailed morphological analyses.


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 ...
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...
Post-paleocene deformation in Kalecik region, East of Ankara, Turkey
Kasımoğlu, Pınar; Rojay, Fuat Bora; Department of Geological Engineering (2010)
In order to understand the tectonic evolution of the Kalecik region (Ankara, Turkey), a structural field study was performed in a selected area located in the east of Kalecik, where mostly imbricated thrust sheets of the Cretaceous Ophiolitic melange crop out. In the study area, the Cretaceous Ophiolitic melange, Cretaceous radiolaria-bearing sequences and the Paleocene units are all intruded by sub-vertical dykes. The attitudes of planar structures (dykes, beds and faults) and the kinematic data measured o...
Mineralogical, petrographical and geochemical properties of zeolite bearing tuffs in nw Anatolia (Turkey)
Özen, Sevgi; Göncüoğlu, Mehmet Cemal; Department of Geological Engineering (2008)
The purpose of this study is to understand the geological, petrographical, mineralogical and geochemical characteristics of analcime-bearing tuffs in the Biga Peninsula and to determine formation process of these tuffs. The study area lies between Ayvacık and Küçükkuyu. The rock units are pre-Eocene basement rocks, Miocene Behram Volcanics (Arıklı Tuff, andesite, andesitic agglomerate), Pliocene volcanics, Miocene lacustrine sediments (Küçükkuyu Formation) and Quaternary alluvium. Analcimes which are found ...
