Short summary
Short summary
Rocks are brought to great depths and back to the Earth's surface by the tectonic processes that shape mountain ranges. Tiny mineral inclusions can record how deep rocks went. Quartz, a common mineral inclusion, was put in the laboratory at conditions that mimic those encountered at depths to about 100 km. A laser-based spectroscopy (Raman) was calibrated to read pressure from quartz inclusions in rocks and to unravel their deep travel.

Short summary
Elastic thermobarometry is an useful tool to recover paleo-pressure and temperature. Here, we provide an analytical model based on the Eshelby solution to calculate the residual stress and strain preserved in a mineral inclusion exhumed from depth. The method applies to ellipsoidal, anisotropic inclusions in infinite isotropic hosts. A finite-element method is also used for a facet effect. Volumetrically averaged stress is shown to be a good proxy for the overall heterogeneous stress stage.

Short summary
Understanding porous fluid flow is key for many geology applications. Traditional methods cannot resolve cases with sharp discontinuities in hydraulic/mechanical properties across those layers. Here we present a new space-time method that can handle such discontinuities. This approach is coupled with trace element transport. Our study reveals that the layering of rocks significantly influences the formation of fluid-rich channels and the material distribution adjacent to discontinuities.

Short summary
Our research focuses on improving the way we predict mineral assemblage. Current methods, while accurate, are slowed by complex calculations. We developed a new approach that simplifies these calculations and speeds them up significantly using a technique called the BFGS algorithm. This breakthrough reduces computation time by more than five times, potentially unlocking new horizons in modeling reactive magmatic systems.

Short summary
We quantify the relative importance of forces driving the dynamics of mountain building using two-dimensional computer simulations of long-term coupled lithosphere–upper-mantle deformation. Buoyancy forces can be as high as shear forces induced by far-field plate motion and should be considered when studying the formation of mountain ranges. The strength of rocks flooring the oceans and the density structure of the crust control deep rock cycling and the topographic elevation of orogens.

Short summary
Western Norwegian “diamond facies” eclogite contains tiny mineral inclusions of quartz and amphibole lamellae that are not stable in the diamond field. Low trace amounts of water in the lamellae-bearing host minerals suggest that the inclusion microstructure was not formed by fluid infiltration but by dehydration during early exhumation of these rocks. Some samples with higher water content argue that a late fluid overprint was spatially restricted and erased evidence of extreme metamorphism.

Original geochemical data for the vast Cenozoic arc magmatism of Iran introduce three distinct rock series rooted in the mantle wedge. The LILE-rich and LILE-poor series show wet-slab melt metasomatism and dry-slab melt metasomatism signatures respectively. The third series rich in incompatible elements, ITE-rich, indicate the input of asthenosphere as well. Eocene-Early Miocene ages for the three series imply that the metasomatic events predate Eocene and the three series occur intermittently.

Plate tectonics theory is the motion of rocky plates (lithosphere) over ductile zones (asthenosphere). The causes of the lithosphere–asthenosphere boundary (LAB) are controversial; however, petit-spot volcanism supports the presence of melt at the LAB. We conducted geochemistry, geochronology, and geochemical modeling of petit-spot volcanoes on the western Pacific Plate, and the results suggested that carbonatite melt and recycled oceanic crust induced the partial melting at the LAB.

The capacity of aqueous fluids to mobilize rare Earth elements is closely related to their molecular structure. In this study, first-principle molecular dynamics simulations are used to investigate the complex formation of yttrium with chloride and fluoride under subduction-zone conditions. The simulations predict that yttrium–fluoride complexes are more stable than their yttrium–chloride counterparts but likely less abundant due to the very low fluoride ion concentration in natural systems.

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.

Understanding the anatomy of active magmatic plumbing systems is essential to define the heat source(s) feeding geothermal fields. Mineral-melt thermobarometry and fractional crystallization (FC) models were applied to Quaternary volcanic products of the Los Humeros Caldera (Mexico). Results point to a magmatic system controlled by FC processes and made of magma transport and storage layers within the crust, with significant implications on structure and longevity of the geothermal reservoir.

We report a peridotite xenolith-bearing basalt dredged from the Seifu Seamount (SSM basalt) in the northeast Tsushima Basin, southwest Sea of Japan, which is one of the western Pacific back-arc basin swarms. An 40Ar / 39Ar plateau age of 8.33 ± 0.15 Ma (2 σ) was obtained for the SSM basalt, indicating that it erupted shortly after the termination of back-arc spreading. The SSM basalt was formed in a post-back-arc extension setting by the low-degree partial melting of an upwelling asthenosphere.

Short summary
We study the petrographical and geochemical occurrence of magmatic sulfide minerals in volcanic rocks for areas characterised by different geodynamic settings, some of which are associated with porphyry (Cu and/or Au) and Au epithermal mineralisation. The aim is to investigate the role of magmatic sulfide saturation processes in depth for ore generation in the surface.

Short summary
In this study, we present a 1-D visco-elasto-plastic model in a spherical coordinate system to study the residual pressure preserved in mineral inclusions. This allows one to study how much residual pressure can be preserved after viscous relaxation. An example of quartz inclusion in garnet host is studied and it is found that above 600–700 °C, substantial viscous relaxation will occur. If one uses the relaxed residual quartz pressure for barometry, erroneous results will be obtained.
