Garnet is a high-pressure mineral that may incorporate very small amounts of water in its structure (tens to hundreds of micrograms per gram H2O). In this study, we show, based on analysis and modelling, that it can transport up to several hundred micrograms per gram of H2O at depths over 80 km in a subduction zone. The analysis of garnet from the various rock types present in a subducted slab allowed us to estimate the contribution of garnet in the deep cycling of water in the earth.

How, and how fast, does hydrogen move through crystals? We consider this question by adding hydrogen, by diffusion, to synthetic crystals of olivine doped with trace amounts of chromium. Even in a highly simplified system, the behaviour of hydrogen is complex. Hydrogen can move into and through the crystal using various pathways (different defects within the crystal) and hop between these pathways too.

Short summary
This study presents an approach that combines equilibrium thermodynamic modelling with oxygen isotope fractionation modelling for investigating fluid–rock interaction in metamorphic systems. An application to subduction zones shows that chemical and isotopic zoning in minerals can be used to determine feasible fluid sources and the conditions of interaction. Slab-derived fluids can cause oxygen isotope variations in the mantle wedge that may result in anomalous isotopic signatures of arc lavas.

The mineral tourmaline records the geologic environment in which it crystallizes. Methods were developed for laser-induced breakdown spectroscopy analysis of tourmaline. Problems that were solved include the spacing between analysis locations to avoid the recast layer from previous analyses, the efficacy of using cleaning shots prior to data acquisition, the number of analyses needed to obtain a representative average analysis, and the effect of spectrometer drift on multivariate analysis.

We study Icelandic silica sinter samples formed in hot-spring environments to evaluate the effect of both temperature and microstructure on the spectral properties of hydrothermal opal. We show that spectral changes can be related to different parameters such as fluid temperatures, hydrodynamics, microbial activity, and silica micro-textures, which are specific to their environment of formation within hot-spring geothermal contexts.

The infrared spectrum of hydrous defects in corundum is routinely used in gemology, but the assignment of absorption bands to specific defects remains elusive. Here, we theoretically study selected defects and compare the results with available experimental data. The main results are the assignment of the
3161 cm−1 seriesto OH groups associated with Fe2+ ions and the interpretation of bands below 2700 cm−1 in corundum containing divalent cations in terms of overtones of OH bending modes.

Since As is detrimental to the environment, the As content of ores should be reduced before it is released into the atmosphere through a smelting process. Thus, Raman spectra of typical As minerals were investigated, and these can be used in the industrial removal of As-rich ores prior to the ore beneficiation. An additional objective of our study was an investigation of the secondary products of enargite weathering. They play a decisive role in the release or retainment of As in the waste form.

We provide a tool for fast preparation-free estimation of the Fe3+ content in Al–Fe3+ series epidotes by Raman spectroscopy. The peaks near 570, 600, and 1090 cm−1, originating from Si2O7 vibrations, strongly correlated with Fe content, and all three signals are well resolved in a random orientation. Among them, the 570 cm−1 peak is the sharpest and easily recognized. Hence, the linear trend, ω570 = 577.1(3) − 12.7(4)x, gives highly reliable Fe content, x, with accuracy ± 0.04 Fe3+ apfu.

Assignment of OH-stretching bands to specific atomic-scale environments in tourmaline is still debated, which motivates detailed theoretical studies of their vibrational properties. We have theoretically investigated the OH-stretching spectrum of foitite, showing that specific OH bands observed in the vibrational spectra of iron-rich and Na-deficient tourmalines are affected by the magnetic configuration of iron ions and X-site vacancy ordering.

The near-infrared spectra of hydrous minerals involve OH stretching vibrations, but their interpretation is not straightforward due to anharmonicity and vibrational coupling. We analyze the spectra of well-ordered samples of talc, brucite and lizardite to better assess the various factors contributing to the absorption bands. The results clarify the relations between the overtone spectra and their fundamental counterparts and provide a sound interpretation of the two-phonon combination bands.

Combined Raman-scattering and wavelength-dispersive electron microprobe (WD-EMP) analyses of natural biotites expanding over the whole biotite solid-solution series demonstrate that the chemical composition of the MO6 octahedra, TO4 tetrahedra, and interlayer space can be non-destructively determined by Raman spectroscopy with relative uncertainties below 8 %. The content of critical minor elements such as Ti at the octahedral site can be quantified as well with a relative error of ~ 20 %.

Rocks containing the serpentine mineral lizardite occur in many tectonic settings. Knowing the crystal orientation of lizardite in these rocks tells us how they deform and gives insights into their physical properties. The crystal orientation of lizardite is challenging to obtain using standard techniques. To overcome this challenge, we developed a method using Raman spectroscopy to map the crystal orientation of lizardite with minimal preparation on standard thin sections.

Common energy dispersive methods cannot accurately analyze low concentrations of cobalt in pyrite due to the overlapping of cobalt and iron peaks. The Raman method, on the other hand, has been shown to be very sensitive to a trace amount of cobalt. In addition, it can be applied on a rough surface, does not require a vacuum chamber, and operates with a laser instead of X-rays. Thus, Raman has the potential to be used as an assaying tool for Co-bearing pyrite.

Information about the local structure of tourmaline-group minerals can be obtained from the characteristic OH stretching bands in their vibrational spectra. However, their assignment to specific atomic-scale environments is debated. We address this question theoretically by investigating a series of dravite models. Our results support a local role of cationic occupancies in determining the OH stretching frequencies and bring constraints for the interpretation of the vibrational spectra.

Interpretation of vibrational spectra of serpentines is complexified by the common occurrence of divalent and trivalent cationic impurities at tetrahedral and octahedral sites. We theoretically investigate the effect of Fe and Al on the vibrational properties of lizardite, focusing on the OH stretching modes. The results allow us to disentangle the specific effects related to the valence and coordination states of the impurities, supporting a detailed interpretation of the experimental spectra.

The study provides new insights into the OH stretching vibrations of serpentine species (lizardite, chrysotile, antigorite) encountered in veins of peridotite. A combination of infrared spectroscopy in the mid-infrared and near-infrared ranges and Raman spectroscopy enabled us to interpret most of the observed bands in the fundamental and first overtone regions of the spectra and to propose consistent spectral decomposition and assignment of the OH stretching bands for the serpentine species.

Unusually large lizardite (Lz) crystals from Monte Fico serpentinites, Elba (Mellini and Viti, 1994), have allowed several subsequent studies. During a µ-Raman study of serpentine minerals (Compagnoni et al., 2021), the careful microscopic examination of this Lz showed
spongymicrostructure. TEM observations confirmed that the Lz hosts voids, filled with chrysotile and polygonal serpentine; their mutual relationships indicate that Lz grew up with a skeletal habit and fibres epitactically.

The infrared absorption spectrum of an antigorite sample, an important serpentine-group mineral, is compared to its theoretical counterpart computed at the density functional level. The model reproduces most of the observed bands, supporting their assignment to specific vibrational modes. The results provide robust interpretations of the significant differences observed between the antigorite spectrum and that of lizardite, the more symmetric serpentine variety.

Carbonophosphates (sidorenkite, bonshtedtite, and bradleyite) with the general formula Na3MCO3PO4 (M is Mn, Fe, and Mg) are often found in inclusions of carbonatite and kimberlite minerals. This article presents the results of Raman spectroscopic study and a simple algorithm for diagnosing mineral phases of the carbonophosphate group. This work may be of interest both to researchers of carbonatites and/or kimberlites and to a wide range of specialists in the field of Raman spectroscopy.

The OH overtone bands of kaolinite- and serpentine-group minerals observed in their near-infrared (NIR) spectra are widely used but their relation to stretching modes involving coupled OH groups is uncertain. Here, we map a molecular model of harmonically coupled anharmonic oscillators on the spectroscopic properties of 1:1 phyllosilicates. This makes it possible to interpret most of the observed bands and support the assignment of some of them to cationic substitutions in serpentines.

The atomic-scale geometry of hydrous defects in diopside is still imperfectly known despite their contribution to the Earth's water cycle. Their OH-stretching vibrations lead to a variety of infrared absorption bands. Low-temperature infrared spectroscopy makes it possible to resolve additional bands in the spectra of gem-quality natural samples. Theoretical results obtained at the density functional theory level support the assignment of the observed bands to specific atomic-scale models.

The structural response of the NH4+ molecule to temperature and pressure changes is studied in ammonium phengite. The symmetry of the molecule is lowered by increasing P or decreasing T; the type and mechanism of this lowered symmetry is different in both cases. Devolatilisation (NH4+ and OH loss) of ammonium phengite is studied as well. This study confirms the wide stability range of phengite and its volatiles and thus has important implications for N and H recycling into the deep Earth.

Corundum is an important oxide mineral which can contain low amounts of hydrogen-bearing structural defects. These defects are observed by infrared spectroscopy, but their atomic-scale geometry is still uncertain. Here, a theoretical approach makes it possible to relate most of the observed infrared bands to specific atomic configurations, highlighting the key role of other chemical impurities and defect clustering in the high-temperature incorporation of hydrogen in corundum.

Short summary
Although rutile does not have water in its chemical formula, it can contain trace amounts. We applied a new measurement protocol to study water incorporation into rutile from eight geological environments. H2O in natural rutile can be linked to six crystal defects, most importantly to Ti3+ and Fe3+. Quantifying the H2O in the individual defects can help us understand relationships of trace elements in rutile and might give us valuable information on the conditions under which the rock formed.
Although rutile does not have water in its chemical formula, it can contain trace amounts. We...
