Abstract

The characterization of some structural properties of quartz in the sand dunes of region of Ouargla was performed by IR spectroscopy and X-ray diffraction. The FTIR absorption shows that the characteristic doublet for α- quartz at 797 and 778 cm-1. The degree of crystallinity can be found by measuring the absorption ratio. The calculated absorption ratio of =1.5 indictated that the sample exhibits a highly crystalline nature. The observed principle reflections at the d-spacings of 4.2681, 3.3539, 1.8204 Å confirm the presence of α-quartz crystalline structure in the sample. The structural resolution of this phase, carried out with the program Dicvol 06 gave: Quartz (SiO2), hexagonal system, space group P3221 (154) . The calculated unit cell parameters are : a=4.9294 Å, c=5.4093 Å V=113.832 Å3.
