Mineralogical and sorption capacity characteristics of Ankara Clay, which is widespread around the Ankara region, Turkey, have been studied for the purpose of its potential use as a landfill liner. This clay is Pliocene in age and was deposited in a fluvial environment. Mineralogically it consists mainly of illite, smectite, chlorite and kaolinite minerals. The non- clay minerals, quartz, feldspars, calcite and Fe-Ti oxides are detected. Its cation exchange capacity (CEC) is determined as 41 meq/100 g using the Ag-Tu method. The retention of the heavy metal cations follows the order of Pb2+ > Cu2+ > Zn2+ > Mn2+, Cd2+. These characteristics, together with its known engineering properties, suggest that Ankara Clay can be utilized as a component of a barrier system. These findings also indicate the potential usage of widespread occurring fluvial clays as landfill liners.

Mineralogy, chemistry and potential utilization of clays from coal deposits in the Kutahya province, Western Turkey Tuerkmenoglu, Asuman Guenal; Yavuz-Isik, Nurdan (Elsevier BV, 2008-12-01) Kutahya graben is one of the largest E-W trending grabens of Western Turkey consisting of Tavsanli and Seyitomer sub-basins filled with Neogene continental deposits. These deposits contain economic lignite seams and the clay samples investigated in this study are closely related to the commercial lignite deposits since they occur underlying or overlying the major coal seams and also intercalated with them.
Hydroelectric power potential and its use in Turkey Taşdemiroğlu, Erol (Elsevier BV, 1988-7) Hydroelectric development in Turkey is briefly reviewed. The results of estimates of gross and economically exploitable hydroelectric power potentials are compared. Dam sites and their order for construction are identified. Present and future developments in the power sector are analyzed and projections are given for electricity consumption and production to the year 2010. Hydraulic, thermal and nuclear contributions to total electricity generation are discussed. Finally, problems associated with hydroelect...
Regional and temporal variations in CO2/He-3, He-3/He-4 and delta C-13 along the North Anatolian Fault Zone, Turkey De Leeuw, G. A. M.; Hilton, D. R.; Güleç, Nilgün Türkan; Mutlu, H. (Elsevier BV, 2010-04-01) New He and C relative abundance, isotope and concentration results from nine geothermal locations situated along an 800-km transect of the North Anatolian Fault Zone (NAFZ), Turkey, that were monitored during the period November 2001-November 2004, are reported. The geothermal waters were collected every 3-6 months to study possible links between temporal geochemical variations and seismic activity along the NAFZ. At the nine sample locations, the He isotope ratios range from 0.24 to 2.3R(A), delta C-13 val...
Hydrothermal alteration products in the vicinity of the Ahirozu kaolin deposits, Mihaliccik-Eskisehir, Turkey Sayit, Isil Omeroglu; Günal Türkmenoğlu, Asuman; Sayin, S. Ali; Demirci, Cengiz (Mineralogical Society, 2018-06-01) The mineralogy, texture and composition of rocks associated with the kaolin deposits in the Ahirozu-Hamidiye-Ucbasli area, SE of Mihaliccik, Eskisehir, Turkey, were investigated. In the study area, Triassic, blue-green schists and serpentinized ultramafic rocks are exposed. Kaolinization occurs at the contact between a Triassic granitic intrusion and metamorphic rocks. Textural and mineralogical characteristics were identified by X-ray diffraction (XRD) and scanning electron microscopy-energy dispersive X-r...
GEOCHEMICAL CHARACTER OF THE HYDROTHERMAL ALTERATION ZONES AROUND THE MADENKOY-SIIRT MASSIVE SULFIDE DEPOSIT AND IMPLICATIONS FOR GEOCHEMICAL-EXPLORATION ERLER, A (Elsevier BV, 1989-04-01) The Madenkoy-Siir region lies in southeastern Anatolia, Turkey to the northeast of Siirt. The study area is in the southeastern Anatolian Thrust Belt, which forms the boundary between the Border Folds on the northern edge of the Arabian plate and the Taurids. In the region, limestones of the Midyat Group of Eocene-Miocene age and alternating marls and sandstones of the Lice Formation of Early-Middle Miocene age are the autochthonous units. Three thrust slices were emplaced over the autochthonous units durin...
