In Anatolia which is one of exceptional continental regions hosting both Neogene volcanism and tectonism, the geothermal potential is quite high due to unique geological and tectonic structures. In recent years, the geothermal resources in western Anatolia, whose geothermal potential is well defined, are successfully used in a wide range of applications such as energy production, district heating, thermal tourism and greenhouse heating. However, the geothermal resources of northeastern Anatolia (NEA) have been used only in limited local-scale applications such as thermal tourism. Some of the geothermal fields in NEA region have been studied partly using physicochemical and isotopic techniques, leading to an understanding of water-rock interaction and origin of fluids. However, geothermal potential of these resources was not investigated from the perspective of hydrogeological conceptual model. In this study, hydrogeochemical properties and reservoir temperatures of 36 geothermal springs from 17 different geothermal fields in NEA region are investigated (in Ardahan, Artvin, Erzincan, Erzurum, Kars and Rize provinces). Waters which are of mostly NaHCO3 character have temperature, pH and specific electrical conductivity values varying between 18.57-63.20°C, 5.33-9.76 and 194-9580 µS/cm, respectively. The reservoir temperatures of Akdağ, Çat, Horasan and Ilıca (Erzurum) geothermal fields computed by Na/K and K/Mg geothermometers typically range from 70- 170°C and 48-88°C. The Na/K geothermometer results for the Köprüköy, Pasinler, Tekman and Uzunahmet (Erzurum) geothermal fields seem to be unrealistic (>160°C) while the temperatures calculated by K/Mg geothermometer are 45-87°C. A remarkable reservoir temperature of 107°C is obtained by K/Mg geothermometer for the Ġkizdere field (Rize). The Na/K geothermometers yield varying results between 71-123°C for Ayder while results from K/Mg geothermometer are similar to discharge temperatures. For low-temperature geothermal fields in the Artvin and Kars provinces, reservoir temperatures by K/Mg geothermometer are estimated between 71- 123°C.

GEOLOGICAL AND GEOCHEMICAL EVIDENCE FOR A LATE CRETACEOUS CONTINENTAL ARC IN THE CENTRAL PONTIDES, NORTHERN TURKEY
Ellero, Alessandro; Ottria, Giuseppe; Sayıt, Kaan; Catanzariti, Rita; Frassi, Chiara; Göncüoğlu, Mehmet Cemal; Marroni, Michele; Pandolfi, Luca (2015-01-01)
In the Central Pontides (Northern Turkey), south of Tosya, a tectonic unit consisting of not-metamorphic volcanic rocks and overlying sedimentary succession is exposed inside a fault-bounded elongated block. It is restrained within a wide shear zone, where the Intra-Pontide suture zone, the Sakarya terrane and the Izmir-Ankara-Erzincan suture zone are juxtaposed as result of strike-slip activity of the North Anatolian shear zone. The volcanic rocks are mainly basalts and basaltic andesites (with their pyroc...
Hydrochemistry isotopic ratios and origin of thermal fluids in eastern Anatolia
Aydın, Harun; Karakuş, Hüseyin; Mutlu, Halim; Güleç, Nilgün Türkan; Hılton, Davıd (2016-09-25)
As a result of active volcanism and tectonism, the eastern Anatolian region in Turkey is represented by a high geothermal potential. In this study, we evaluate chemical and isotopic compositions of several geothermal springs in eastern Anatolia with emphasis on hydrochemical/isotopic characteristics and reservoir temperatures. Thermal waters were sampled in areas of Miocene volcanism (northeastern Anatolia) whilst some are collected in localities near historically-active volcanoes (e.g. Ağrı, Tendürek and S...
Palaeoenvironmental and chronological constraints on the Tuglu Formation (Cankiri Basin, Central Anatolia, Turkey)
Mazzini, Ilaria; Hudackova, Natalia; Joniak, Peter; Kovacova, Marianna; Mikes, Tamas; Mulch, Andreas; Rojay, Fuat Bora; Lucifora, Stella; Esu, Daniela; Soulie-Maersche, Ingeborg (2013-01-01)
The Cankiri Basin, located in the northern part of the Central Anatolian Plateau, is a large Tertiary basin where thick Miocene to Quaternary continental sediments overlay the Cretaceous-Tertiary units. This investigation focuses on the Tuglu Formation, an Upper Miocene succession mainly composed of dark grey silty and organic rich clays. The type section of Tuglu has been sampled for an array of multidisciplinary analyses. The palaeontological proxies included ostracod, foraminifer, nannoplankton, pollen, ...
Tectonic history of basins sited along the western section of the North Anatolian Fault System, Turkey
SARP, Gülcan; Gurboga, Sule; Toprak, Vedat; Duzgun, Sebnem (2014-01-01)
Geological and geomorphological features of basins along the western half of the North Anatolian Fault System (NAFS) are used to constrain the formation of these basins by localization of deformation and the total displacement, and to determine the timing of basin development. In this study, tectonic influence direction of the NAFS on tectonic and hydrologic basins Bolu, Yenicaga, Dortdivan, Cerkes, Ilgaz and Tosya has been investigated to deduce information about the formation stages and interaction betwee...
Numerical simulation of germencik geothermal field
Hamendi, Ahmed; Parlaktuna, Mahmut; Department of Petroleum and Natural Gas Engineering (2009)
The Germencik Omerbeyli geothermal field is considered to be one of the most important geothermal fields in Turkey. A numerical modeling study was carried out to simulate the response of the field to different production/injection scenarios. The reservoir performance evaluation was based on the numerical simulation of the reservoir behavior using the simulation code TOUGH2. The numerical simulation model includes a total area of 85.8 km2 and extends from the surface at +330 m msl (mean sea level) to a depth...
