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...
Hydrogeochemical Properties of Geothermal Fields at Northeastern Anatolia
Aydın, Harun; Karakuş, Hüseyin; Mutlu, Halim; Güleç, Nilgün Türkan; Hılton, Davıd (null; 2016-05-16)
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 b...
Hydrogeochemical investigation of groundwater characteristics in Alpu coal field, Eskisehir-Turkey
Tural, Ceren Yazıgülü; Çamur, Mehmet Zeki; Department of Geological Engineering (2021-6)
Hydrogeochemical characteristics and quality of groundwater resources in Alpu Coal field to the north of Porsuk Creek are investigated. EC, pH, DO and ORP average value ranges are determined as 438-1227 μS/cm, 7.43-8.69, 3.29-6.05 mg/l and 106-180 mv, respectively in spring waters and as 452-30233 μS/cm, 7.46-8.48, 0.6-6.0 mg/l ve 198- -183 mv, respectively in well waters. All spring waters are in HCO3 - Mg, Mix(Ca-Mg), Ca facies. Groundwater facies, stratigraphically downward: change in the order of HCO3, ...
Hydrogeochemical characterization and conceptual modeling of the Edremit geothermal field (NW Turkey)
Avşar, Özgür; Güleç, Nilgün Türkan; Parlaktuna, Mahmut (Elsevier BV, 2013-07-15)
The Edremit geothermal field, with 42-62 degrees C discharge temperatures, is utilized for space heating. Alternation of permeable and impermeable units created two superimposed aquifers in the area: an upper unconfined and a lower confined. Water samples from 21 (hot-cold) wells were taken in this study. 8 of these wells penetrate the deeper confined aquifer, while 13 penetrate the shallower unconfined aquifer. Geochemical analyses revealed that Na + K - SO4 (>40 degrees C), Ca - HCO3 (<30 degrees C) and C...
Hydrothermal vents as a kinetically stable source of iron-sulphide-bearing nanoparticles to the ocean
Yücel, Mustafa; Chan, Clara S.; Luther, George W. (2011-06-01)
Hydrothermal vents emit sulphur and metals to the ocean(1). Particular attention has been paid to hydrothermal fluxes of iron(2-4), a limiting micronutrient of marine primary production(5). Vent-derived iron was previously thought to rapidly oxidize and precipitate around vents(6). However, organic matter can bind to and stabilize dissolved and particulate iron in hydrothermal plumes(7-9), facilitating its dispersion into the open ocean(10). Here, we report measurements of the chemical speciation of sulphid...
