Measurement of crystallographic orientation of quartz crystal using Raman spectroscopy: application to entrapped inclusions

Abstract: Raman spectroscopy has been widely used in mineralogy and petrology for identifying mineral phases. Some recent applications of Raman spectroscopy involve measuring the residual pressure of mineral inclusions, such as quartz inclusions in garnet host, to recover the entrapment pressure condition during metamorphism. The crystallographic orientations of entrapped inclusions and host are important to know for the modelling of their elastic interaction. However, the analysis of tiny entrapped mineral inclusions u… Show more

Figure A11 Normal Raman spectra from solids: (A) oPD Sigma P-9029 (75 mW, 785 nm, 15 s accumulation time); (B) oPD∙2HCl Alfa Aesar J60354 (240 mW, 785 nm, 15 s accumulation time); (C) synthesized oPD∙2HCl (same acquisition conditions as B).
Providing trustworthy information about the vibrational bands of particular molecules, Raman spectra from solid substances may not be straightforward to compare with SERS spectra due to several complications: Raman spectra from solids may contain lattice modes; Some shifts in band positions and intensities may occur due to interactions between molecules in the crystal; For anisotropic crystals, slight shifts in the band positions and possibly large changes in the relative intensities may occur due to the preferred crystal orientation [ 58 ]. The Raman spectrum from the water solution, typically with a lower signal-to-noise ratio compared to one from a solid, nevertheless provides additional insights into the vibrational bands of the molecule in the well-separated and solvent-surrounded state.…”

“…Raman spectroscopy, a versatile technique for nondestructive analysis and high spatial resolution, is especially valuable for inclusion studies and high-temperature and high-pressure experiments. Because the intensity ratio (α I ) and area ratio (α A ) of Raman spectra are indicators of various physical properties, they are used in widely various fields to estimate, for example, volatile compositions of fluid inclusions, [1][2][3][4][5] viscosities of silicate melts, 6 composition and structural properties of silicate glasses, [7][8][9] H 2 O and OH contents in silicate glasses or minerals, [10][11][12][13] crystallographic orientations, [14][15][16][17] and chemical compositions of minerals. 18,19 Obtaining the most accurate estimates of α I and α A is a crucially important goal for all these applications, for which the highest probable precision is desirable.…”

“…Raman spectroscopy is potentially a useful tool for determining the crystallographic orientation of some minerals (Zhong et al, 2021;Ishibashi et al, 2008;Tesar et al, 2019). This is based on comparing the polarisation directions and intensities of select Raman modes for a range of orientations relative to polarisation (Zhong et al, 2021).…”

This is based on comparing the polarisation directions and intensities of select Raman modes for a range of orientations relative to polarisation (Zhong et al, 2021). Unlike EBSD that typically has an interaction volume extending only 10-50 nm below the sample surface (depending on material density and acceleration voltage) (Van De Moortèle et al, 2010), the detection volume for confocal Raman spectroscopy with a high numerical aperture objective can extend up to 1-2 µm below the surface, depending on the properties of the measured material.…”
