Çiçekdağı basin developed on the Central Anatolian Crystalline Complex (CACC) is a foreland basin developed as the southern integral part of the Çankırı Basin during the Late Paleocene to middle Oligocene. The basin has two compartments separated by the Çiçekdağı High comprises two sedimentary cycles. The oldest cycle comprises Baraklı, Kocaçay and Boğazköy formationsa and is exposed both in the northern and the southern sectors. They were deposited in marine conditions. The second cycle comprises İncik and Güvendik formations and was deposited in continental settings. The first cycle comprises uniformly south-directed paleocurrent directions in both the northern and southern sectors whereas the second cycle deposits are represented by south-directed directions in the southern sector, and bimodal directions in the northern sector. In addition, the second cycle formations contain progressive unconformities and coarsening upwards sequences indicative of thrusting. Internal structures of the units and paleostress data indicate that the basin experienced over-all compression and local extension due to flexural bending. This gave way to inversion of some of the normal faults and uplift of the Çiçekdağı High during the deposition of second cycle in the Late Eocene to middle Oligocene time which subsequently resulted in compartmentalization of the basin.

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 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 ...
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...
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...
Modeling and development of a groundwater management plan for Ulubey aquifer system, Uşak-Turkey Ünsal Erdemli, Burcu; Yazıcıgil, Hasan; Department of Geological Engineering (2008) The purpose of this study is the characterization and modeling of Ulubey aquifer system which serves as an important water supply for Uşak province located in inner parts of the Aegean Region in Turkey. In recent years, growing population, accelarating industrial activities and on the contrary decreasing rainfall and contamination of the surface water resources made groundwater indispensable to meet domestic, agricultural and industrial water demands of Uşak province. All these facts necessitate the develop...
