The main concern of the study is the definition of mud-based materials technologies belonging to Ulucak Höyük (İzmir) Neolithic settlement (Vth level:6400-6000 BC and IVth level: 5990-5660 BC). Representative samples were collected from the eight different mud masonry houses that were unburnt, partially and fully burnt mudbricks, interior/exterior mud plasters, and floor covering mud mortars. Their laboratory tests were based on raw materials analyses composed of compositional properties of mud mixtures and mineralogical composition of clay content together with basic physical and physicomechanical properties analyses. Mineralogical composition of raw materials was identified by the cross-section and thin section analyses using an optical microscope, X-ray diffraction, FTIR analyses. The presence of a mica-illite group of clay with or without kaolinite, clay-sized CaCO3 particles in clay mixture and coarse gravel in a certain amount are the main characteristics that highlight the qualified composition of mud-based construction materials belonging to Ulucak Höyük Neolithic settlement and the advanced mud-materials technology achieved in that period. The mud-based brick, floor covering mortar and interior plaster have different bulk densities in coherence with their particular grain size distribution. The clay type, percentage of clay content, percentage of CaCO3 in clay content, presence of kaolinite in clay content are the indicators introduced in the study in order to examine the neighbouring clay and adobe soil resources and to discuss the archaeological questions on social life in relation to settlement period and building construction. The data achieved are guiding for planning conservation approaches on mud materials of the settlement.

Analysis of Plio-Quaternary deep marine systems and their evolution in a compressional tectonic regime, Eastern Black Sea Basin Sipahioglu, N. O.; Karahanoğlu, Nurkan; Altıner, Demir (Elsevier BV, 2013-05-01) Facies architecture of submarine fans and channel-levee complexes in the Eastern Black Sea Basin and their evolution from the Late Miocene until the present day are studied using a three-dimensional seismic data set covering an area of approximately 1161 km(2). The interpretation of the observations reveals the outcome of the changing interplay between rate of sedimentation and compressional tectonism in the area through time.
Assessment of temporal variation and sources of PCBs in the sediments of Mediterranean Sea, Mersin Bay, Turkey Gedik, Kadir; İmamoğlu, İpek (Elsevier BV, 2011-01-01) Information on temporal distribution of polychlorinated biphenyls (PCBs) in the coastal sediments of Mediterranean Sea, Mersin was compiled using data published between 1980 and 2009, and the present study. The first congener specific PCB results from the region yield concentration levels of Sigma(41) PCBs in sediments ranging from 0.61 to 1.04 ng g(-1). Sediment profiles show penta-, hexa- and hepta-chlorobiphenyls, specifically, #149 and 153 as the most abundant congeners in all samples. Comparison of tot...
A geochemical approach to Neogene-Quaternary volcanic activity of western Anatolia: An example of episodic bimodal volcanism within the Selendi Basin, Turkey Ersoy, Y.; Helvaci, C.; Sozbilir, H.; ERKÜL, FUAT; Bozkurt, Erdin (2008-09-30) New radiometric age and geochemical data are presented from the late Cenozoic volcanic activity in the Selendi Basin of western Anatolia. Stratigraphical and age data show that the volcanism occurred in four distinct stages from the early Miocene to Quaternary. The first early Miocene stage includes two volcanic units with contrasting compositions: the Egreltidag volcanic unit and the Kuzayir lamproite. These volcanic units interfinger with the sedimentary rocks of the early Miocene Hacibekir Group. The Egr...
Assessment of discrimination of mafic rocks using trace element systematics with machine learning Öztürk, Mehmet Sinan; Sayıt, Kaan; Department of Geological Engineering (2019) Having an important role in the elucidation of the evolution of ancient oceans and related continental fragments, the determination of original tectonic settings of ancient igneous rocks is an essential part of the geodynamic inferences. Geochemical classification of mafic rocks is important for the tectono-magmatic discrimination of igneous rocks especially when geological information is insufficient as the link of the igneous rocks to their original tectonic setting had been erased due to large scale even...
Evaluation of glaciation and glacial shapes using geographic information systems and remote sensing (Eastern Black Sea) Geçen, Reşat; Toprak, Vedat; Tombul, Saadettin; Department of Geodetic and Geographical Information Technologies (2011) This study investigates the actual glaciers and the major properties of glacial landscapes (valleys, cirques and lakes) located over the Eastern Black Sea mountain chain using Geographic Information Systems (GIS) and Remote Sensing (RS) technologies. A database is created for each glacial feature that includes fundamental properties of each landscape. Data layers used in the study include digital and analog topographic maps, satellite images, geological maps and drainage maps. The studies carried out yielde...
