“…Tuzla is an active geothermal area hosted by rhyolite lava and pyroclastic deposits. Geothermal brine is found in a shallow volcanic reservoir at a depth of between 330-350 m and a deep granite reservoir at a depth of 1,020 m (Vengosh et al, 2002). TGF is an interesting area in Turkey from the point of its temperature and dissolved ions in the water.…”

“…According to previous studies, Tuzla geothermal brine originates from the dissolution of marine evaporates and is formed by chemical alteration (dissolution of halite, dolomitization, reduction of sulphate, precipitation of anhydrite, digenetic reactions of silicates, Ca and Na ion exchange and reactions with organic matter), which generates the higher mineralization. Alternate models for the origin of the TGF include derivation from relics of evaporated seawater trapped in sediments (Balderer, 1997;Mützenberg, 1997), dissolution of Messinian evaporites (Vengosh et al, 2002) and trapped relict seawater within pore spaces in rocks (Yalcin, 2007).

“…The coastal thermal waters at northern Republic of Djibouti [1], Greece [2,3], Turkey [4][5][6], and West Coast of India [7] are significantly affected by seawater, resulting in high salinity. However, despite being coastal geothermal systems, the coastal thermal waters at North Chile [8] and Sri Lanka Island [9], for instance, are much more diluted by the respective local meteoric fresh water, and those with high salinity appeared to be related to water-rock interactions [10] and mixing with brine [5] instead of seawater.…”

Two separate groups of geothermal waters have been identified in the coastal region of Guangdong, China. One is Xinzhou thermal water of regional groundwater flow system in a granite batholith and the other is thermal water derived from shallow coastal aquifers in Shenzao geothermal field, characterized by high salinity. The hydrochemical characteristics of the thermal waters were examined and characterized as Na-Cl and Ca-Na-Cl types, which are very similar to that of seawater. The hydrochemical evolution is revealed by analyzing the correlations of components versus Cl and their relative changes for different water samples, reflecting different extents of water-rock interactions and clear mixing trends with seawaters. Nevertheless, isotopic data indicate that thermal waters are all of the meteoric origins. Isotopic data also allowed determination of different recharge elevations and presentation of different mixing proportions of seawater with thermal waters. The reservoir temperatures were estimated by chemical geothermometries and validated by fluid-mineral equilibrium calculations. The most reliable estimates of reservoir temperature lie in the range of 148-162 ∘ C for Xinzhou and the range of 135-144 ∘ C for Shenzao thermal waters, based on the retrograde and prograde solubilities of anhydrite and chalcedony. Finally, a schematic cross-sectional fault-hydrology conceptual model was proposed.

“…As a result of this, geothermal waters with high B concentrations dramatically affect the quality of shallow groundwater in Western Turkey (Gemici and Tarcan 2002;Vengosh et al 2002;Baba et al 2009). The pollution problem caused by boron mining activities has been studied before (DSI 1971(DSI , 1983Urgüplü 1985;Onacak 1990;Wolkersdorfer 1996;Akbas 1998;Iller Bankası 2000;Rural Service of Eskisehir Research Institute 2001, 2003Ugurluoglu 2004;Yasin and Yuce 2008).…”

The Province of Kirka (Eskisehir, Turkey), located in the catchment of the Seydisuyu Plain, has one of the largest Naborate deposits in the world. However, boron concentrations in surface and ground waters downstream of Kirka Province, the Seyitgazi Plain, have increased over the past twenty years. Seyitgazi plain has been widely irrigated from groundwater and Seydisuyu River. In this respect, quality of the river water directly affects groundwater quality in the Seyitgazi Plain since river water is the main supplier for irrigation water in the Seyitgazi plain in addition to groundwater which is extracted from the wells drilled in the Seyitgazi Plain. Thus, any mining activity built in the catchment area of groundwater poses potential risk for the quality of groundwater in the discharge area.The Seydisuyu River is fed from Catören and Kunduzlar dam reservoirs which are located in the upper reaches of the Seyitgazi Plain. Chemical analysis of surface waters (n = 102) and groundwaters (n = 136) showed that boron concentrations in groundwater of the Seyitgazi Plain increased up to three to four times due to infiltration into the shallow aquifer system because the Seydisuyu River water is used for irrigation. Statistically, significant positive correlations were found between boron and arsenic due to deposition in the same playa lake. Since the boron bearing layers can contain arsenic minerals, arsenic can act in a tracer role for surplus boron concentrations in groundwater. Besides natural contribution, mining activities caused a substantial increase in boron and arsenic concentrations in the groundwater of the Seyitgazi Plain.
