Raman spectroscopy is now used considerably in the Earth sciences as a structural and/or chemical characterisation technique for natural samples and synthetic analogues, from fluids to minerals and organic compounds, but also as an in situ technique in experimental cells where parameters like pressure, temperature and/or oxygen fugacity are controlled. Over the last years, there has been a considerable improvement in the versatility of the instruments and performances, especially for Raman imaging which now offers versatile opportunities. In parallel, there is a growing demand for theoretical knowledge and consistent reference spectral databases. The goal of this session is to gather Raman-oriented studies in all fields of the Earth sciences and beyond. All methodological or technological new aspects of Raman spectroscopy, theoretical approaches as well as discussions of the advantages/limits of the technique are encouraged to be presented.
