    Trace elements in groundwaters of Konya urban area, Turkey
    (2006) Nalbantcilar M.T.; Güzel A.
    Groundwater is the main source of supply for drinking, industrial and agricultural usage in Konya urban area of southwestern Turkey. The water pollution which is of some concern in the area is mainly by industrial waste-disposals and agricultural activities. The present investigation has revealed the presence of As, Ba, Cd, Cu, Fe, Pb, TI and Zn in the groundwater with concentrations ranging from 0 to 0.009250, 0.0650 to 0.7989, 0 to 0.00277, 0.000121 to 0.035797, 0.002327 to 0.307340, 0 to 0.002851, 0.00558 to 0.04618, and 0.001248 to 0.056130 ppm respectively. The analysis results were compared with the standards of EPA, WHO and EC. The concentrations of TI and Pb are higher than the maximum allowable level, and Ba is at such levels to cause grave health risk. © Geol. Soc. India.

    Some geological and hydrogeochemical characteristics of geothermal fields of turkey
    (2010) S̈ǧ̈t A.R.; Güzel A.; Zedef V.; Bayram A.F.
    Presently, active hydrothermal areas of Turkey can be divided into three major provinces which correlate particular volcano-tectonic features. These fields are essentially found at western, central and eastern part of the country. There has been no particular geothermal energy fields in the southern part of Turkey since this region is mostly covered by ~2 km thick carbonate sequences and has suffered little recent rifting. The western Turkish geothermal provinces, where horst and graben systems are well developed, have the hottest fluids among others. In this region, normal faults penetrate into the crust and thus the meteoric waters are heated to greater temperatures than in the east where a compressional tectonic regime dominates. In the western Turkish geothermal fields, the fluids have a distinctly higher pH (>7) values than those in the east. This resulted that the Si content of the western Turkish hydrothermal fluids is considerably higher than the others. The geothermal field at Tuzla, situated on the Aegean shore in NW Turkey, has ionic component twice that of conventional seawater. Because of this, the area provides a good opportunity to investigate the interactions between seawater and hot dry rock.

    Stratigraphic Characteristics of the Derinkuyu Area, Nevsehir, Turkey
    (Springer, 2014) Sogut A.R.; Kocak K.; Güzel A.
    The study area is located in the Derinkuyu area, central Anatolia. The oldest formation in the area is Cretaceous Karatepe hornblende gabbro, which is overlain by upper Miocene Melendizdağı tuffs, Melendizdağı andesites, Gostuk tuff and ignimbrite, and the Karakaya Formation. These units are followed by lower Pliocene Selime tuff, Kızılkaya ignimbrite, and the Ağıllı Formation, above which lie various Pleistocene ashes, namely, the Hasandağı ash, the Kumtepe ash, and the Göllüdağ ash flow tuffs. Above these are the Pleistocene Kızıldag basalts and Holocene basaltic cinder cones. Talus is the youngest unit in the area. The young volcanics and volcaniclastics in the area may have originated from the volcanism of Mts Erciyes, Melendiz, and Hasan. © 2014, Springer-Verlag Berlin Heidelberg.
