The Eocene deposits of Kazan Basin in Turkey contain a rare trona mineral which is planned to be extracted by solution mining. The complex flow dynamics and mixing mechanisms as noted from previous hydraulic and hydrochemical data need to be augmented with environmental tracer and noble gas data to develop a conceptual model of the system for the assessment of the impacts of the mining and to develop sustainable groundwater management policies throughout the area. The tracers used include the stable isotopes of water (delta H-2, delta O-18), delta C-13 and C-14 of dissolved inorganic carbon (DIC), tritium (H-3), the chlorofluorocarbons CFC-11 and CFC-12, and the noble gases He and Ne. The system studied consists of three aquifers: shallow, middle, and deep. CFC data indicate modern recharge in the shallow system. The estimates of ages through C-14 dating for the deeper aquifer system are up to 34,000 years. Helium concentrations cover a wide range of values from 5 x 10(-8) to 1.5 x 10(-5) cm(3) STP/g. He-3/He-4 ratios vary from 0.09R(A) to 1.29R(A) (where R-A is the atmospheric He-3/He-4 ratio of 1.384 x 10(-6)), the highest found in water from the shallow aquifer. Mantle-derived He-3 is present in some of the samples indicating upward groundwater movement, possibly along a NE-SW-striking fault-like feature in the basin.

Environmental isotopic evaluation of the springs located in Kazan Trona basin in Central Turkey ARSLAN, Sebnem; Yazıcıgil, Hasan (2012-11-01) Kazan Trona ore field, the second discovered deposit in Central Turkey, is planned to be extracted by solution mining technology. Understanding the hydrogeology of the springs in such an area is vital since they can be affected during mining operations. The aim of this study is to provide an isotopic approach by utilizing environmental isotope techniques to the springs in the study area, thereby, to enhance the understanding of their occurrence by complementing the previous geochemical studies. Here, the is...
Assessment of Dewatering Requirements and Dewatering Well Design for an Open Pit Coal Mine in Central Anatolia Peksezer Sayıt, Ayşe; Yazıcıgil, Hasan (2022-09-01) The celtikci Coal Basin is a newly discovered coal basin in Central Anatolia where 11 years of open-cut mining has been planned. The bulk of the mining will be conducted below the regional water table; hence, determination of the dewatering requirements and proper design of the dewatering wells plays a critical role. This study (i) defined the dewatering requirements of the open-pit mine, (ii) established a dewatering well design for the area, and (iii) assessed the anticipated impacts of the dewatering act...
Modeling of lithology induced chemical anomalies in the aquifer systems of the Kazan Trona deposit area, Ankara, Turkey Çamur, Mehmet Zeki; Yazıcıgil, Hasan (2008-04-01) The study was carried out in order to investigate existing hydrogeochemical relationships between groundwater environment and geological units in the Kazan trona deposit area, Ankara, Turkey. Evaluations indicate that concentrations of alkalinity, boron, chloride and sodium in the upgradient groundwater of the Eocene sedimentary units gradually increase toward downgradient by the interactions of saline minerals (searlesite, shortite, northupite and pyrite) present in the secondary structures (microfractures...
Evaluation of the alkali reactivity of cherts from Turkey Bektas, F.; Topal, Tamer; Göncüoğlu, Mehmet Cemal; TURANLI, LUTFULLAH (2008-06-01) Chert, which is a crypto and/or microcrystalline sedimentary rock, may lead to alkali-silica reaction in concrete when the conditions are favorable. However, cherts vary in composition and consequently may demonstrate different reaction characteristic. In this study, eight different chert types were investigated. Accelerated mortar bar test, ASTM C 1260, was performed on aggregate blends of limestone and chert. Ten sets of mortar bars with varying amount of cherts, 1 to 100%, were tested for each chert type...
Assessment of water supply impacts for a mine site in Western Turkey Ağartan, Elif; Yazıcıgil, Hasan; Department of Geological Engineering (2010) A certain amount of water is required for a mine site located in Turgutlu in Western Turkey to be used in mining processes. The purpose of this study is to assess the impacts associated with meeting water supply requirements for the mine. Scope of the study involves determination of the alternative water resources, the assessment of impacts associated with each resource and the selection of the most feasible alternative in the aspect of environmental and technical effects. Three alternatives suggested to su...
