Investigation of Cappadocia Volcanic Tuffs by X-ray Diffraction (XRD) Method

Abstract

Stone samples taken from volcanic tuffs at seven different locations in the Cappadocia region were examined. In order to obtain the powder diffraction pattern of the samples, they were pulverized by grinding in agate mortar. Diffraction patterns were taken on a Bruker AXS D8 Advance Model diffractometer. Qualitative analysis of the pattern data was performed using the XRD Evolution program. The most common compounds as a result of the analysis; It has been identified as Silicon Oxide [SiO2], Magnesium Silicate Hydroxide [Mg3(Si2O5)(OH)4], Sodium Calcium Aluminum Silicate [(Na0.45Ca0.55)(Al1.55Si2.45O8)], Sodium Calcium Magnesium Aluminum Iron Titanium Aluminum Silicon Oxide Hydroxide Hydrate [(Mg2.46Al0.3Fe0.22Ti0.021)2(Mg0.38Ca0.03Na0.02)2((Si2.83 Al1.17)O10)2 (OH)4(H2O)3.4], Potassium Aluminum Silicate Hydroxide [(K, Ca, Na)(Al, Mg, Fe)2(Si, Al)4O10(OH)2], Sodium Magnesium Aluminum Iron Silicon Oxide Hydroxide Hydrate [Na0.930Mg2.810Fe0.065Al1.185Si2.895O10(OH)2 (H2O)3], Calcium Magnesium Aluminum Silicate Hydroxide Hydrate [Ca0.2 (Al, Mg)2Si4O10(OH)2 • xH2O].
