Inclusions in natural rocks are an invaluable asset for geoscientists because they provide information about processes in the Earth's history that are otherwise hidden or subsequently overprinted. In this paper we review the development over the last 200 years of the concepts and methods to measure the remnant pressures in mineral inclusions and how they can be used to determine pressures and temperatures at which the inclusions were formed deep within the Earth.

Heimaeyite (Na3Al(SO4)3) has been found in fumaroles on Eldfell volcano, which lies on the island of Heimaey, Iceland. Its crystal structure contains Al–sulfate chains and belongs to a known structure type that also comprises K–Nb, K–Ta, Na–V, and Na–Fe representatives. We registered small Fe–Al substitution in heimaeyite, which might indicate a solid solution between Na–Al and Na–Fe compounds. We investigated the specimen with electron microscopy, an electron microprobe, and X-ray diffraction.

The discovery of the K-dominant tourmaline maruyamaite with microdiamond inclusions suggested its ultrahigh-pressure formation. We analyzed the role of K in the tourmaline structure, with a special focus on its stability. High pressure is necessary to squeeze the large cation K+ in the stiff framework of tourmaline, although K is the underdog component if Na+ is present in the mineralizing fluid. K-tourmaline is stable at high pressure, overcoming the stereotype of a mere crustal component.

In this work we have applied the elastic geobarometry approach to a Chinese diamond in order to determine the depth of formation of an olivine-bearing diamond. Together with the temperature of residence at which the diamond resided in the mantle, we were able to discover that the diamond was formed at about 190 km depth. Beyond the geological meaning of our results, this work could be a reference paper for future works on Chinese diamonds using elastic geobarometry.

Bobtraillite is an extremely rare cyclosilicate with a unique composition and complex structure. In this paper, we describe the second occurrence of the extremely rare complex zirconium silicate. The results suggest that the ideal formula of bobtraillite could be written as (Na, □)12(□, Na)12Sr12Zr14(Si3O9)10[Si2BO7(OH)2]6·12H2O.

We determined the physical conditions at the time of its entrapment for an inclusion pair hosted in a Siberian diamond (Udachnaya kimberlite) and found that it equilibrated under relatively oxidized conditions, near the enstatite–magnesite–olivine–diamond (EMOD) buffer, similarly to Udachnaya xenoliths originating from comparable depths. These results can be reconciled with models suggesting relatively oxidized, water-rich CHO fluids as the most likely parents for lithospheric diamonds.

This work provides updated scenario on the underrepresentation of women in the Italian university system in the area of geosciences in the last two decades. Data highlight an increase in the number of female full and associate professors whereas the low number of female non-permanent researchers raises strong concerns. Over different areas of geosciences, Paleontology represents the only field in which the gap is filled whereas all the other disciplines suffer a gender imbalance.

This study introduces an innovative method to analyze carbon isotopes in tiny amounts of CO2 produced during experiments that simulate conditions deep within the Earth. Using advanced tools, we measured both the composition and isotopic signature of CO2 in carbon-bearing fluids. This enables new studies of carbon exchange between rocks and fluids under extreme conditions, offering new insights into processes driving the deep carbon cycle and, ultimately, controlling the climate of our planet.

The CaSiO3 system exhibits structural complexity with various polymorphs under different pressure and temperature conditions. This study stabilizes a new high-pressure polymorph, parabreyite, via multianvil syntheses at 4–5 GPa and 600–800 °C. Parabreyite's triclinic structure, with distinct threefold tetrahedral rings, was solved using 3D electron diffraction and X-ray diffraction. Elastic properties, thermal expansion and Raman spectra differences with breyite were analyzed.

The growing interest in lithium (Li) diffusion for the determination of timescales of magmatic events increases the necessity to better understand Li diffusion in common mineral phases. In this context we analyzed Li diffusion in plagioclase, one of the most common mineral phases. Our study is the first to confirm two diffusion mechanisms for Li in plagioclase, and our results indicate timescales derived from Li diffusion data in previous studies were underestimated by a factor of up to 100.

Kamafugites are rare ultrabasic/basic K2O-rich rocks. High-pressure–high-temperature experiments on four samples from the known type localities (Italy, Brazil, Uganda) constrained their melting assemblage, unlike a classical peridotite. Clinopyroxene and phlogopite are the first near-liquidus phases. Olivine appears in two runs. The different abundances of the main phases and the variable contribution of apatite, oxides and titanite explain the variegated kamafugite geochemical features.

We experimentally investigated the behavior of chrome in high-pressure post-spinel oxide phases. Only minor amounts of Cr can be incorporated into Fe5O6. But there is full solid solution between Fe4O5 and Fe2Cr2O5 and Mg2Fe2O5 and Mg2Cr2O5, in spite of a phase transition occurring in the middle of the compositional range. Our results provide further constraints on the formation of such oxide phases in extraterrestrial materials and inclusions in natural diamonds.

We studied the exchange of chemical elements by diffusion between magmas of tephritic and phonolitic composition from the Canary Islands, performing experiments at high pressure and high temperature with different amounts of added water. Our results characterize the way water and temperature affect the diffusion process, and we also find unexpectedly high mobility of aluminium, which may be related to its variable chemical bonding in highly alkaline melts.

Mechanical interaction between quartz inclusions in garnet creates residual pressure in the inclusion used to calculate the pressure and temperature where the two minerals formed. We crystallised quartz and garnet at high pressure and temperature and then adjusted the experimental pressure to observe the interaction between the quartz inclusions and garnet host. The quartz and garnet adjust to the new experimental pressures, reset inclusion pressures, and no longer match entrapment conditions.

To explore the influence of the redox state of the environment on the serpentinization reaction, we have developed an original experimental setup. Reducing conditions, leading to the formation of serpentine and magnetite, and oxidizing conditions, leading to the formation of serpentine and hematite, are discussed in terms of analogues of low- and high-permeability hydrothermal systems, respectively. The influence of the redox on brucite stability and hydrogen production is also established.

Li is a critical element that is often enriched in pegmatites. To better understand the enrichment of Li in such systems, it is necessary to understand the underlying transport mechanisms. We performed experiments to investigate diffusion rates and exchange mechanisms of Li between a Li-rich and a Li-poor melt at high temperature and pressure. Our results indicate that fluxing elements do not increase the diffusivity of Li compared to a flux-free melt.

The furnace can sustain temperatures of up to 1650 °C. This furnace sets itself apart with its size and unique quench mechanism. Crucially, the apparatus has the ability to change the gas mixture during an experiment. This feature allows the user to simulate natural environments, such as volcanoes.

Volatile diffusivities in silicate melts control the nucleation and growth of bubbles in ascending magma. We investigated the diffusion of CO2 in an anhydrous and hydrous leucititic melt at high temperatures and high pressure. CO2 diffusion profiles were measured via attenuated total reflection Fourier transform infrared spectroscopy. CO2 diffusion increases with increasing temperature and water content. The data can be used to understand the CO2 degassing behaviour of leucititic melts.

Carbonates reduce the melting point of the mantle, and carbonate melts produced in low-degree melting of a carbonated mantle are considered the precursor of CO2-rich magmas. We established experimentally the melting relations of carbonates up to 9 GPa, showing that Mg-carbonates melt incongruently to periclase and carbonate melt. The trace element signature of carbonate melts parental to kimberlites is approached by melting of Mg-rich carbonates.

Magmas transport large amounts of CO2 from Earth's mantle into the atmosphere and thus contribute significantly to the global carbon cycle. We have developed an experimental method to homogenize at high pressure small liquid droplets trapped in magmatic crystals to gain access to the initial composition of the parental magma (major and volatile elements). With this technique, we show that magmas produced by melting of the subcontinental mantle contain several weight percent of CO2.

This review provides an overview of ex situ carbon-saturated COH fluid experiments at upper-mantle conditions. Several authors experimentally investigated the effect of COH fluids. However, fluid composition is rarely tackled as a quantitative issue, and rather infrequently fluids are analyzed as the associated solid phases in the experimental assemblage. Recently, improved techniques have been proposed for analyses of COH fluids, leading to significant advancement in fluid characterization.

Amphibole–liquid partitioning of elements of geological relevance is experimentally derived at conditions compatible with those of the Earth's upper mantle. Experiments are carried out at different oxygen fugacity conditions and variable Cl content in order to investigate their influence on the amphibole–liquid partition coefficients. Our results point to the capability of amphibole to act as filter for trace elements at upper-mantle conditions, oxidized conditions, and Cl-rich environments.

Detailed knowledge of the mechanisms ruling water incorporation in amphibole is essential to understand how much water can be fixed at upper-mantle conditions by this mineral. We provide the experimental evidence of the Cl effect on the oxo-substitution and the incorporation of water in amphibole. Finally, we highlight the versatility of confocal micro-Raman spectroscopy as an analytical tool to quantify water in amphibole.

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.

Grain boundary diffusion is orders of magnitude faster compared to volume diffusion. We studied this fast transport process in a well-defined garnet grain boundary. State-of-the-art microscopy was used for quantification. A dedicated numerical diffusion model shows that iron diffusion requires the operation of two diffusion modes, one fast, one slow. We conclude that impurity bulk diffusion in garnet aggregates is always dominated by grain boundary diffusion.

Short summary
Short summary
We experimentally explored direct entrapment of breyite (CaSiO3) by diamond at upper-mantle conditions in a model subducted sediment rather than formation by retrogression of CaSiO3 perovskite, implying a deeper origin. Anhydrous low-T melting of CaCO3+SiO2 precludes breyite formation. Under hydrous conditions, reduction of melt results in graphite with breyite. Thus, breyite inclusions in natural diamond may form from aragonite + coesite or carbonate melt at 6–8 GPa via reduction with water.

Short summary
We have developed the thermodynamic theory of the properties of inclusions consisting of more than one phase, including inclusions containing solids plus a fluid. We present a software utility that enables for the first time the entrapment conditions of multiphase inclusions to be determined from the measurement of their internal pressure when that is measured in a laboratory.
We have developed the thermodynamic theory of the properties of inclusions consisting of more...
