Raman Spektroskopisinin İlkeleri ve Mineral Tanımlamalarında Kullanılması

Abstract

The detailed nomenclature and descriptions of the minerals can be made with the aid of a polarizing microscope on the thin section and by powdering with the X-Ray Diffraction (XRD) method. In both methods, minerals are damaged and require serious knowledge and experience. In Raman spectroscopy without any destruction of the sample, the spectra formed as a result of differences in the wavelength of the scattered light compared to the wavelength of the light that interacts with the molecule by being sent on the mineral can reflect the identity of the mineral. The spectra, which consist of the molecular composition difference of each mineral, can also reflect the changes of the measured mineral. Furthermore, in addition to mineral naming, fresh and altered mineral differences are also distinguished by this method. In this study, Raman spectroscopic definitions of plagioclase, orthoclase, anorthoclase, biotite, phlogopite and garnet minerals were made using the Raman spectroscopy method and comments were made on the origin of the rock from which they were formed. Thus, the determination of the types of minerals by non-destructive analysis method has been demonstrated with examples.
