“…[59] Raman spectroscopy is also being used for in situ measurements of glasses at high temperature and pressure and has the potential for remote use on planetary surfaces. [57,[60][61][62][63][64] Similarly, the strategy employed to define physical properties of natural multicomponent melts could be adopted in compositional subgroups of material relevant for in industrial processes where continuous monitoring of melt and glass properties during production is important. [65,66] Our calibration strategy demonstrates the possibility to directly compare and interchange Raman data from silicate glasses collected (a) with different spectrometers, (b) in different labs, and (c) under different conditions, and (d) it obviates the need for measurements of melt composition and, thus, can expedite estimations of melt viscosity in various natural environments and, as a consequence, of various natural processes (e.g., melting, assimilation, and mixing of magmas) also where individual melt compositions are not easily sampled or measured (e.g., mixed magmas) or where research questions demand very large datasets of melt composition and physical properties.…”

The physical properties of silicate melts are of critical importance for understanding magmatic and volcanic processes on Earth and other planets. Most physical properties of melts are, ultimately, a consequence of the structural organization of the melt. Robust and fully generalizable strategies for the prediction of properties of naturally occurring melts as functions of composition, temperature, and pressure remain a challenging goal. Given the structural origin of macroscopic properties, Raman spectroscopy of glasses, which provides information on melt and glass structure, may provide a useful technique to understanding and quantify variations in macroscopic melt properties. Here, with the aim of providing a generalizable model for predicting the viscosity of silicate melts, we present the results of a Raman spectroscopy campaign performed on 30 anhydrous multicomponent silicate glasses resulting from quenching of remelted and homogenized volcanic rocks and synthetic equivalents. The sample suite comprises one of the largest databases of multicomponent melts for which (a) chemical compositions and (b) physical properties (i.e., viscosity, fragility, heat capacity, and glass transition temperature) are known. Raman spectra have been collected using green light sources at wavelengths of 532 nm. Spectra were collected on the same sample suite in four independent laboratories involving instruments from different manufacturers and, thus, using different spectrometers, detectors, and analytical conditions. Our results are also compared and integrated with published data on some of the same samples derived from two others setups using green light sources with 514.5 and 532 nm wavelegths. For the same sample, the Raman spectra acquired using different setups show different intensities and intensity ratios. However, a strategy based on the ratio between the low‐ and high‐wavenumber peaks (R) was developed to standardize the data to normalized Raman ratios (Rn) and thus to remove interlaboratory differences. Using these advances, we predict melt viscosity solely with the use of Raman spectral measurements of multicomponent silicate glasses, thus demonstrating the potential of the method in describing physical properties of silicate melts.

“…ExoMars program). Indeed, in the last years, Raman spectroscopy has been recognized as a promising tool for in situ and/or remote investigation of organic and inorganic material of bodies in our solar system . In particular, it has been demonstrated that Raman spectroscopy can be used both in situ and in remote conditions up to 100 m [e.g.…”

The effect of chemical composition on the Raman spectra of a series of natural calcalkaline silicate glasses has been quantified by performing electron microprobe analyses and obtaining Raman spectra on glassy filaments (~450 µm) derived from a magma mingling experiment. The results provide a robust compositionally‐dependent database for the Raman spectra of natural silicate glasses along the calcalkaline series. An empirical model based on both the acquired Raman spectra and an ideal mixing equation between calcalkaline basaltic and rhyolitic end‐members is constructed enabling the estimation of the chemical composition and degree of polymerization of silicate glasses using Raman spectra. The model is relatively insensitive to acquisition conditions and has been validated using the MPI‐DING geochemical standard glasses1 as well as further samples. The methods and model developed here offer several advantages compared with other analytical and spectroscopic methods such as infrared spectroscopy, X‐ray fluorescence spectroscopy, electron and ion microprobe analyses, inasmuch as Raman spectroscopy can be performed with a high spatial resolution (1 µm2) without the need for any sample preparation as a nondestructive technique. This study represents an advance in efforts to provide the first database of Raman spectra for natural silicate glasses and yields a new approach for the treatment of Raman spectra, which allows us to extract approximate information about the chemical composition of natural silicate glasses using Raman spectroscopy. We anticipate its application in handheld in situ terrestrial field studies of silicate glasses under extreme conditions (e.g. extraterrestrial and submarine environments). © 2015 The Authors Journal of Raman Spectroscopy Published by John Wiley & Sons Ltd

“…Remote Raman spectroscopy from orbiting instruments would be a new tool for the investigation of planets. Klein et al (2004) presented the results of various feasibility studies commissioned by the European Space Agency to apply a remote Raman measurement device 10-100 m away from the landing site on a planetary body or even from the orbiting instruments. Their studies revealed that remote Raman spectroscopy will be a demanding task.…”
