The Ni-rich mineral phases constituting the Ni-ores in New Caledonia are dominated in most cases by kerolite–pimelite series, also called talc-like minerals. Despite their economic and geologic interests, the crystallographic structures of these minerals are not fully understood. In order to improve the knowledge of their crystallographic structure...
The Variscan French Massif Central (FMC) is classically described as a stack of nappes with increasing metamorphism from the bottom (parautochthonous unit) to the top (lower and upper gneiss units). Ultra-high pressure (UHP) metamorphism was already recognized in the uppermost units, with notably coesite-bearing rocks. We report the first finding o...
Raman microspectrometry of water in individual aqueous fluid inclusions can provide chemical information about fluid composition, in particular the concentration of chloride ions. The regular method consists in correlating the deformation of the OH stretching vibration band of liquid water in the region assigned to hydrogen-bonded OH groups with ch...
Salinity of fluid inclusions is usually determined by microthermometry, but it becomes unsuitable in case of metastability of the aqueous fluid because of thermodynamics indetermination. Raman microspectrometry of water in individual aqueous fluid inclusions can provide chemical information about fluid composition, in particular the concentration o...

Due to their numerous isotopic similarities to terrestrial rocks, enstatite chondrites (ECs) are commonly proposed as Earth’s main building blocks. Although ECs contain sufficient H concentrations to account for the mass of Earth’s oceans, the physicochemical process(es) behind their H incorporation remain under constrained. Here, we combined secon...
Carbon Capture, Utilization and Storage (CCUS) is one of the mitigation approaches that can be used to control CO2 emissions into the atmosphere and to limit global warming. The CO2 stream injected underground may contain small amounts of associated gaseous components such as SO2. One of the key parameters needed to predict the physical and chemica...

European Climate Law, establishing the aim of reaching net zero greenhouse gas emissions (GHG) in the EU by 2050, sets an intermediate target of reducing GHG by at least 55% by 2030 compared to 1990 levels. Achieving this goal requires the implementation of conventional abatement technologies such as energy efficiency, the abandonment when possible...
Aqueous magmatic fluids are essential to the transport of hydrogen (H), carbon (C), and nitrogen (N) from the mantle to the surface, during which changes in pressure, temperature, and redox conditions affect the chemical speciation and intermolecular isotopic fractionations of H, C, and N. Here, we performed a series of hydrothermal diamond-anvil c...
Comprehensive mineralogical and petrographic studies require analytical methods capable to report the distribution of major to trace elements within crystals in order to unravel their formation conditions and subsequent evolution. Additionally, the investigation of transition elements (e.g., Ti, V, Cr, Mn, Fe, and Zn) is essential for the comprehen...

Many experimental calibration data linking the variation of Raman spectral parameters (i.e., peak position, peak area/intensity ratio …) with the PVX properties of pure gases or mixtures of CO2–CH4–N2 or CH4–H2O–NaCl systems have been published in literature by different laboratories. However, there is a significant discrepancy between these calibr...

The relationships between the frequency shift of the ν1 stretching bands of CH4 and N2 with pressure (or density) and composition have been previously provided in the literature as reliable parameters for accurate empirical barometers and densimeters for the direct determination of the pressure or density of gas mixtures. However, the latter result...
In the processes of carbon capture and storage, sulfur and nitrogen oxides (SO x and NO x) would be possibly injected with CO 2 depending on the origin of CO 2.

The P-V-X properties of two-component fluid inclusions (FIs) are generally determined from microthermometry data using appropriate thermodynamic models (i.e., VX diagrams) and/or equations of state (EoS). However, some limitations can hamper the applicability of this technique such as the small size, low density or complex composition of the analyz...

Quantitative analysis of gases by Raman spectroscopy is based on relative Raman scattering cross-sections (RRSCS) and the evolution of different spectral parameters (peak position, peak area, peak intensity, etc.). However, most of the calibration data were established at low pressure (low density) and without evaluating the effect of the compositi...
Density of fluid inclusions is one of the most important parameters to reconstruct the P-T conditions of entrapment of geo-fluids. Co-existing with microthermometry methods, Raman spectroscopy also became a useful tool to determine the density of CO2-bearing inclusions via Fermi diad splitting (Δ). In this study, a new CO2 densimeter which takes in...

The central Grenville Province (Quebec) hosts numerous monazite- or allanite-rich pegmatitic granite dykes that display evidence for a post-tectonic timing of emplacement and a rooting in deep units. Investigations of zircon grains, through U-Pb-Hf-O isotopes and trace element analyses from three of these dykes provide evidence that all dykes were...

Regarding the hydrocarbon source and CO2capture processes, fuel gas from boilers may be accompanied by so-called "annex gases" which could be co-injected in a geological storage.

Microthermometry is the most common technique used to determine the salinity of aqueous fluid inclusions but, in some cases, this technique cannot be applied. The Raman analysis of water is a good alternative. Instead of preparing fluid inclusions within minerals by the crack-and-heal method, fused-silica capillary capsules (FSCCs) were used as syn...
In the framework of CO2 geological storage, one of the critical point
leading to possible massive CO2 leakages is the behavior of the
interfaces crossed by the injection well. The lack of relevant data on
the behavior of these interfaces (rock/well materials) in the presence
of CO2 under high pressure and temperature conditions led to the
developme...

Questions
Question (1)
The Ar+ laser providing high power are not anymore sold. The 514 nm line can be easily replaced by the 532 nm Nd:YAG laser line. But for Raman analysis in the field of mineralogy, the purple line at 457 nm with 200 mW of power is very important in case of fluorescent minerals. Does anyone know if there is solid or diode lasers that can subsitute this line? We need a wavelength in the same range within ~ 10 nm and at least 150 mW power.
