Clay-bearing Upper Pliocene red clastics and Quaternary alluvial deposits occupy the Ankara basin. The clayey levels of the Upper Pliocene deposits, referred to as Ankara clay, is considered as a source for compacted clay liners due to their low coefficients of permeability and widespread distributions throughout Ankara. This study investigates the geological, geotechnical and mineralogical properties of the founding clayey soils at two sites of the Ankara region. The geotechnical index properties along with the hydraulic conductivities of the clayey soil samples collected from these sites were determined. A mathematical relation between the clay mineralogical content and hydraulic conductivity was established. The results of this investigation show that, from a geotechnical point of view, Ankara clay may be regarded as a highly suitable material for a compacted clay landfill liner given that its mineralogical compatibility with leachate is confirmed.

Development of a geotechnical and geophysical database for seismic zonation of the Ankara Basin, Turkey Koçkar, Mustafa K.; Akgün, Haluk (Springer Science and Business Media LLC, 2008-07-01) Engineering geological and geotechnical site characteristics were assessed and seismic hazard studies performed for the Upper Pliocene to Pleistocene fluvial and Quaternary alluvial and terrace deposits for a site west of Ankara, Turkey. Sediment conditions were determined and a soil profile was characterized by surface geophysical methods. These studies were integrated with existing in-situ characterization studies to create a seismic and geotechnical database for the site. A seismic zonation map of the si...
Environmental geological investigations at the Van open dump site, southeastern Turkey Akgün, Haluk (Springer Science and Business Media LLC, 2000-04-01) This study evaluates the geological, hydrogeological and hydrological conditions at the I waste dump site of the Van municipality in eastern Anatolia, Turkey. A geological map and a three-dimensional view of the project site have prepared. All lithological units exposed at and near the dump site have been determined and their boundary relationships identified. Drainage basin characteristics of the dump site along with the water bearing properties of different lithological units have been assessed. For the r...
Environmental effect and genetic influence: a regional cancer predisposition survey in the Zonguldak region of Northwest Turkey KADİR, Selahattin; Onen-Hall, A. Piril; Aydin, S. Nihal; Yakicier, Cengiz; Akarsu, Nurten; Tuncer, Murat (Springer Science and Business Media LLC, 2008-03-01) The Cretaceous-Eocene volcano-sedimentary units of the Zonguldak region of the western Black Sea consist of subalkaline andesite and tuff, and sandstone dominated by smectite, kaolinite, accessory chlorite, illite, mordenite, and analcime associated with feldspar, quartz, opal-CT, amphibole, and calcite. Kaolinization, chloritization, sericitization, albitization, Fe-Ti-oxidation, and the presence of zeolite, epidote, and illite in andesitic rocks and tuffaceous materials developed as a result of the degrad...
Quality assessment of armourstone for a rubble mound breakwater (Sinop, Turkey) Topal, Tamer (Springer Science and Business Media LLC, 2004-10-01) Helaldi is a fishing town in the central Black Sea region where construction of a rubble mound breakwater is being planned. The construction of the breakwater requires good quality durable armourstone. Several laboratory tests are performed for the quality assessment of the two potential armourstone, namely, limestone and sandstone. The quality evaluation of the stones is done on the basis of CIRIA/CUR criteria, saturation coefficient, wet-to-dry strength ratio, and the rock durability index. The quality ev...
Contamination of the cement raw material in a quarry site by seawater intrusion, Darica-Turkey Çamur, Mehmet Zeki (Springer Science and Business Media LLC, 2008-02-01) The open pit mining nearby shoreline is planned to be extended into below sea level in order to use additional reserves of the cement raw material (marl). The raw material is currently contaminated by seawater intrusion below a depth of 20 m up to the distance of 90 m from shoreline. Seawater intrusion related contamination of the material used for the cement production was investigated by means of diffusion process for the future two below sea level mining scenarios covering 43 years of period. According t...
