The purpose of this study is to evaluate systematic fairy chimney development within Cappadocian ignimbrites. The first step in the sudy is to identify fairy chimney producing ignimbrites. Accordingly the fairy chimneys are formed within Kavak ignimbrite, at Kavak-Zelve transition, and within Zelve and Cemilköy ignimbrites. Field measurements are taken from the fairy chimneys to quantify the shape and the size. Slope of the selected areas are identified to investigate the most suitable topography. Analysis have shown that fairy chimneys have basal diameters ranging from 9.7 to 13.7 m, with heights in the range from 8.41 to 21.73 m. The slopes of fairy chimneys are 60 to 70 degrees with a slight asymmetry towards the upslope. The chimneys are sligthy rounded due to the erosion in the slope direction. Distances between the fairy chimneys change from a minimum of 5.45 m for Zelve and 42.72 m for Kavak chimneys. Fairy chimneys are developed in two stages. The first stage is the generation of topography suitable for the formation of fairy chimneys. Three main factors in this stage are degree of welding, thickness of ignimbrite and topographic slope. In the second stage, several local features contribute for the final shaping of the chimneys.

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...
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...
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...
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 ...
