“From lattice dynamics to Equations of State: a simplified approach”

The phonon density of states (pDOS) is responsible for the heat capacity and thermal pressure of solids, but is too complex to introduce into practical equations of state. This lecture will introduce and justify the simplified models for pDOS that can be used in PVT EoS.

Elasticity of minerals in the deep interior of planets as determined by Brillouin scattering measurements

I will introduce the principles of Brillouin scattering and its role in determining mineral elasticity at high-pressure and high-temperature. Example will be given on how the elasticity of minerals coupled with seismic observations can be used to constrain the composition and mineralogy of planetary interiors.

Raman spectroscopy applied to host-inclusion systems: a probe for in
situ mineral rheology at non-ambient conditions

The contrast in the thermoelastic properties between a mineral inclusion and its host leads to residual stresses in the inclusion that change in magnitude and sign as function of different external pressure and temperature conditions. The seminar deals with showing how Raman spectroscopy can be used to quantify residual strain and stress in mineral inclusions at non-ambient conditions and how these data can be used to determine in situ the rheology of minerals undergoing different stress states.

Raman spectroscopy and melt inclusions in metamorphic rocks”

Micrometric melt inclusions in high grade metamorphic rocks tell us the history of the chemical differentiation of the crust through time, and Raman spectroscopy is one of the main tools to rapidly extract reliable information from these tiny objects. We will see examples of how Raman spectroscopy allows us to clarify volatile budgets at depth, find new minerals and new magmatic processes, and understand the origin of peculiar polymorphs of feldspar – the data we need to correctly assess continental subduction and orogenetic processes.

“Raman elastic geothermobarometry of quartz and zircon inclusions in garnet”

Elastic geothermobarometry allows to interpret the conditions of mineral formation in metamorphic rocks from the difference in physical properties between a mineral inclusion and its surrounding host phase. This seminar deals with the basic theory of Raman-based elastic geothermobarometry and its application on quartz and zircon inclusion in garnet, from the initial measurement to the final P-T estimate.

“Raman Crystal Hunter software: application to mineral inclusions in diamonds”

Natural diamonds are the only geological materials capable to preserve fragments of very deep Earth from about 120 to even 1000 km depth through its mineral inclusions. The deepest diamonds are named “super-deep diamonds” (also called sublithospheric diamonds) and are the most intriguing and likely most important diamonds to retrieve geological information on the deepest regions of our planet. Micro Raman spectroscopy is likely the most efficient technique in diamond research to investigate such tiny inclusions.

“Raman spectroscopy: Better do it right!”

The generally increasing interest in using Raman is in harsh contrast to the existing lack of training opportunities. As a result, a significant fraction of published “results” are tainted with uncertainty. The lecture attempts to summarise potential experimental artefacts and common mistakes, and to give hints on how to do proper analysis.


“Application of Raman and photoluminescence spectroscopy in gemstone Analysis”

Both Raman spectroscopy, and the virtually omnipresent “enemy” laser-induced photoluminescence, have various applications in identifying and characterising gemstones. Examples include gem tourmaline, the historical Schneckenstein topaz, and gems in the Imperial Crown of the Holy Roman Empire.

“Symmetry classification of the Raman signals and selection rules”

Vibrational modes can be classified according to the irreducible representations of the point group to which the crystal or the molecule belongs. The symmetry properties of each vibrational mode determine the activity of the mode itself in response to the perturbation caused by the electromagnetic radiation interacting with it. Based on a symmetry analysis it is therefore possible to predict which modes are Raman-active, and under which polarization conditions.

“Raman spectroscopy and mapping: from Earth and planetary sciences to tribology, material sciences, and biology”

Raman spectroscopy and mapping is developed in Earth sciences with the aim of characterizing complex materials potentially submitted to extreme environments. This specificity finds applications in many other fields of science and I show examples of transfer of know-how to various fields based on our work in Lyon.

We will discuss the role of Raman spectroscopy in assessing the thermal maturity of source rocks. Additionally, we will explore how applying Machine learning on Raman spectra can facilitate maceral recognition, aiding thermal maturity assessment of source rocks characterized by complex organic matter assemblages.
