Özet
Bu çalışmada, Niğde ve yakın yöresinde gerek pekmez yapımında gerekse toprak yemede tüketilen toprak ve/veya kayaçların mineralojik ve jeokimyasal özelliklerin belirlenmesi amaçlanmıştır. Bu amaçla Niğde Bor, Ulukışla ve Aksaray-Emirgazi yöresinden 12 adet örnek derlenmiş ve örnekler üzerinde XRD tüm kayaç analizleri gerçekleştirilmiştir. Bu analizler sonucunda Kil, Mika, Karbonat (Kalsit, Dolomit), Kristobalit, Amfibol, Kuvars, Feldispat ve Opal-CT mineralleri belirlenmiştir. Örneklerin tümünde iz element ve ana element analizleri gerçekleştirilmiştir. Ana element dağılımlarında Bor yöresinde CaO+Al2O+Fe2O3; Ulukışla yöresinde CaO+SiO2+Fe2O3; Emirgazi yöresinde CaO+MgO egemenliği gözlenirken, İz element analizinde Bor yöresi örneklerde Sr, Ba, Ce, Zn ve As; Ulukışla yöresinde U, Ce, Ba, Zr, Sr, Ni; Emirgazi yöresinde ise Ba, Sr, La, Ce, Co, Zr elementleri dikkat çekmektedir.Kullanılan tüm örnekler Neojen yaşlı gölsel çökeller olup, özellikle altere olmuş kesimlerdeki halen kazılabilir bölümler tüketilerek kullanılmaktadır.Anahtar sözcükler: Jeofaji, toprak yeme hastalığı, tıbbi jeoloji, kadın, çocuk, anemi, demir eksikliği, pika, mineraloji, Niğde.
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.Keywords: Geophagy, soil eating disease, medical geology, women, children, anaemia, lack of iron, pica, mineralogy, Niğde.
