h i g h l i g h t sPotential environmental impact of high arsenic from geothermal sources was identified. Geothermal waters from deep wells are characterized by Na-HCO 3 type. Hot spring fluids are characterized by Ca-HCO 3 type. As(III) is the dominant species in both deep wells and hot spring fluids. Mixing of geothermal waters containing As is responsible for environmental impact. Arsenic (As) contamination in terrestrial geothermal systems has been identified in many countries worldwide. Concentrations higher than 0.01 mg/L are detrimental to human health. We examined potential consequences for As contamination of freshwater resources based on hydrogeochemical investigations of geothermal waters in deep wells and hot springs collected from western Anatolia, Turkey. We analyzed samples for major ions and trace element concentrations. Temperature of geothermal waters in deep wells showed extreme ranges (40 and 230 • C), while, temperature of hot spring fluids was up to 90 • C. The Piper plot illustrated two dominant water types: Na-HCO 3 − type for geothermal waters in deep wells and Ca-HCO 3 − type for hot spring fluids. Arsenic concentration ranged from 0.03 to 1.5 mg/L. Dominance of reduced As species, i.e., As(III), was observed in our samples. The Eh value ranged between −250 and 119 mV, which suggests diverse geochemical conditions. Some of the measured trace elements were found above the World Health Organization guidelines and Turkish national safe drinking water limits. The variation in pH (range: 6.4-9.3) and As in geothermal waters suggest mixing with groundwater. Mixing of geothermal waters is primarily responsible for contamination of freshwater resources and making them unsuitable for drinking or irrigation.

ABSTRACTThe Gediz River, one of the principal rivers of Western Anatolia, has an extensive Pleistocene fluvial archive that potentially offers a unique window into fluvial system behaviour on the western margins of Asia during the Quaternary. In this paper we review our work on the Quaternary Gediz River Project (2001)(2002)(2003)(2004)(2005)(2006)(2007)(2008)(2009)(2010) and present new data which leads to a revised stratigraphical model for the Early Pleistocene development of this fluvial system.In previous work we confirmed the preservation of eleven buried Early Pleistocene fluvial terraces of the Gediz River (designated GT11, the oldest and highest, to GT1, the youngest and lowest) which lie beneath the basalt-covered plateaux of the Kula Volcanic Province. Deciphering the information locked in this fluvial archive requires the construction of a robust geochronology. Fortunately, the Gediz archive provides ample opportunity for ageconstraint based upon age estimates derived from basaltic lava flows that repeatedly entered the palaeo-Gediz valley floors. In this paper we present, for the first time, our complete dataset of 40 Ar/ 39 Ar age estimates and associated palaeomagnetic measurements. These data, which can be directly related to the underlying fluvial deposits, provide age constraints critical to our understanding of this sequence.The new chronology establishes the onset of Quaternary volcanism at ~1320ka (MIS42). This volcanism, which is associated with GT6, confirms a pre-MIS42 age for terraces GT11-GT7. Evidence from the colluvial sequences directly overlying these early terraces suggests that they formed in response to hydrological and sediment budget changes forced by climatedriven vegetation change. The cyclic formation of terraces and their timing suggests they represent the obliquity-driven climate changes of the Early Pleistocene. By way of contrast the GT5-GT1 terrace sequence, constrained by a lava flow with an age estimate of ~1247ka, span the time-interval MIS42 -MIS38 and therefore do not match the frequency of climate change as previously suggested. The onset of volcanism breaks the simple linkage of terracing to climate-driven change. These younger terraces more likely reflect a localized terracing process triggered by base level changes forced by volcanic eruption and associated reactivation of pre-existing faults, lava dam construction, landsliding and subsequent lavadammed lake drainage.Establishing a firm stratigraphy a...

ÖZBu çalışma, Soma ve Uşak-Güre havzalarındaki kömürlü Miyosen tortulların paleoekolojik özelliklerini ortaya koymaktadır. Soma Havzasındaki palinolojik örnekler Arabacıbozköy yakınındaki sondajdan elde edilmiştir. Sondaj karotunun kalınlığı 425 m olup, genellikle ince kırıntılı tortullar, linyit ve tüfitli seviyelerden oluşmaktadır. Kırıntılı ve linyitli seviyeler içeren bölüm Soma Formasyonuna, volkanik kırıntılı seviyeler içeren bölüm ise Deniş Formasyonuna karşılık gelmektedir. Soma Formasyonundan elde edilen palinolojik topluluk, ayırtlanmamış Pinaceae, Cupressaceae, herdem yeşil Quercus, Quercus spp. ve Alnus formlarını bol miktarda içermektedir. Toplulukta Poaceae ve Ephedra gibi otsul bitkiler düşük oranda gözlenmektedir.
