Geologıcal Characterıstıcs of Soıls Used ın Geophagy (Bor-Emirgazi)

ABSTRACT: The aim of this study was to determine the mineralogical and geochemical properties of the rocks and/or soils consumed for making grape molasses and "eating" which is called geophagy. For this purpose 12 samples were collected from the regions of Niğde Bor, Ulukışla and Aksaray-Emirgazi and full rock analyses were carried out including XRD. As a result; clay, mica, carbonate (calcite, dolomite), cristobalite, amphibole, quartz, feldispar and opal-CT minerals were detected. Elemental and trace element analyses were carried out on all samples. Elemental analyses results showed that elements such as CaO+Al2O+Fe2O3 in Bor; CaO+Si2O+Fe2O3 in Ulukışla; CaO+MgO in Emirgazi regions were dominant. According to trace elemet analyses, concentrations of Sr, Ba, Ce, Zn and As in Bor; U, Ce, Ba, Zr, Sr, Ni in Ulukışla and Ba, Sr, La, Ce, Co, Zr elements in Emirgazi regions drew attention. As a result of these analyses we can say that all samples are lacustrine sediments that are claystone, travertine and dolomite and Neogene aged.
