Bauxite mineralizations of Seydisehir reside in western Taurides, in Konya region. Mesozoic limestones form the base of local stratigraphy. On top of these Eocene aged limestones and flysch units have precipitated. Allochthonous Paleozoic aged limestones of Hadim nappe units have moved on top of all these units. Formations of the region have undergone extensive tectonic activity. Bauxite mineralizations in the region are associated with Mesozoic limestones. They are located in karst spaces of limestones. These spa...

Erenkoy magnesite deposits reside in Eskisehir and Bilecik provinces of northwestern Turkey. Local geology consists of metamorphites of blueschist facies in the base; ophiolitic rocks with mainly serpentinites, peridotites; ophiolitic melanges with a varying range of lithology: cherts, calcschists, blueschist rocks, limestone and on top of all these there are neogene sedimentary units that are mainly consisted of sandstone and clay formations. Magnesite deposits in the area are associated with ultramafic rocks: se...

Barite occurrences east of Istanbul (NW Turkey) are compared major mineralogical and geochemical properties, and identified depositional origins. Sile barite occurrence, which is near Blacksea, north east of Istanbul, is alternated with Triassic sandstone. Petrographic observations reveal that barite grains are found out in the sand stones. Chemical analyses are conducted on eighteen samples via AAS (Atomic Absorption Spectroscopy) equipment for detection of Cu, Zn, Pb, Sr, Cd and Ni concentrations. Because of a v...

Glauberite mineralization from Cayirhan, Ankara (Central Anatolia) has been investigated and identified the major mineralogical, petrographical and geochemical properties. Glauberite occurrence, a sodium calcium sulfate mineral (Na2Ca(SO4)2) by evaporation, is underneath the gypsum mineralization which accumulated at the contact zone between Pliocene aged Ucyatak and Softa formations. The mineralization is related to clay and mudstone, and accompanies with thenardite, gypsum, anhydrite, mirabilite and blodite. Maj...

Preliminary investigation of mineralizations of Thenardite associated with sulfate occurrences in \cCayırhan – Beypazarı, Ankara is presented. Local geology consists of Paleozoic metamorphite schists, Permo-triassic granitic rocks, Middle Jurassic – Upper Cretaceous limestones and marls in flysch facies, Paleocene aged land sedimentaries and marine Eocene units, Miocene to Pliocene aged lacustrine units, which sodium sulfates are associated to. Thenardite, Glauberite and Mirabilite minerals have been detecte...

\cCakraz district of Bartın province in northwestern Turkey contains wide deposits of quartz sand. Regional geology consist of Lias aged carbonated claystones of Himmetpaşa formation, Barremian aged limestone, dolomitic limestones of Zonguldak formation and Aptian aged sandstone – carbonated sandstones of Kilimli formation. \cCakraz district quartz sand deposits are hosted in Himmetpaşa formation and usually occur as wide lenses in the host rocks. In this study major and minor element chemical analysis, petro...

\cCanakkale district, Tuzla region in Turkey houses one of the major geothermal fields of Turkey. Tuzla geothermal field, with its 173 oC temperature is also an important site of weathering and alteration occurrence. Weathering and alteration develops in many different irregular forms and stages in the field. The regional geology consist of volcanics, such as rhyolites, latites, andesites and pyroclastics. Volcanics in the field had been weathered and altered in various stages. Gradual weathering from the outer wa...
