The clay samples are taken from Arapli-Yesilhisar area, located in the southwest part of Kayseri province (CentralAnatolia) have been investigated by the FTIR spectroscopy. The FTIR spectra of clays considered as standard naturalclays including illite, illite-smectite mixed layer, beidellite, kaolinite, chlorite (ripidolite), nontronite, montmorillonitehave been acquired first, and then the spectra of illite+quartz+feldspar, quartz+feldspar have been taken together with thestandard natural clays. Minerals contained by the clay samples have been determined by comparing the both spectra. It isdetermined that the O-H, Si-O, Si-O-Al and Si-O-Fe groups prevail in the FTIR spectral measurements of the samplesrepresenting the lower, middle and upper levels of the Arapli-Yesilhisar profiles. In addition, chemical analyses of theseclay samples indicated major presence of SiO2, TiO2, Al2O3, Fe2O3, MnO, MgO, CaO, Na2O, K2O, Cr2O3 and P2O5. It isfound that the Arapli-Yesilhisar clay samples are mainly illite, kaolinite, feldspar and quartz, and they have T-O(tetrahedral-octahedral) or O-T (octahedral-tetrahedral) structure.
