This work presents LA-ICP-MS U–Pb geochronology of epidote in hydrothermal veins. The challenges of epidote dating are addressed, and a protocol is proposed allowing us to obtain epidote U–Pb ages with a precision as good as 5 % in addition to the initial Pb isotopic composition of the epidote-forming fluid. Epidote demonstrates its potential to be used as a U–Pb geochronometer and as a fluid tracer, allowing us to reconstruct the timing of hydrothermal activity and the origin of the fluid(s).

Predicting the behaviour of magmatic systems is important for understanding Earth's matter and heat transport. Numerical modelling is a technique that can predict complex systems at different scales of space and time, by solving equations using various techniques. This study tests four algorithms to find the best way to transport the melt composition. The "Weighted Essentially Non-Oscillatory" algorithm emerges as the best choice, minimizing errors and preserving system mass.

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.

The Vinschgau Shear Zone (VSZ) is one of the largest and most significant shear zones developed within the Late Cretaceous thrust stack in the Austroalpine domain of the eastern Alps. 40Ar / 39Ar geochronology constrains the activity of the VSZ between 97 and 80 Ma. The decreasing vorticity towards the core of the shear zone, coupled with the younging of mylonites, points to a shear thinning behavior. The deepest units of the Eo-Alpine orogenic wedge were exhumed along the VSZ.

Using experiments that simulate deep tectonic interfaces, known as viscous shear zones, we found that these zones spontaneously develop periodic sheets of small pores. The presence of porous layers in deep rocks undergoing tectonic deformation is significant because it requires a change to the current model of how the Earth deforms. Emergent porous layers in viscous rocks will focus mineralising fluids and could lead to the seismic failure of rocks that are never supposed to have this occur.

We analysed apatite–allanite/epidote coronae around monazite and xenotime in deformed Permian pegmatites from the Austroalpine basement. Microscopy, chemical analysis and EBSD showed that these coronae formed by dissolution–precipitation processes during deformation of the host rocks. Dating of monazite and xenotime confirmed the magmatic origin of the corona cores, while LA-ICP-MS dating of allanite established a date of ~ 60 Ma for corona formation and deformation in the Austroalpine basement.

Based on thermochronological data, we infer thrusting along-strike the northern rim of the Central Alps between 12–4 Ma. While the lithology influences the pattern of thrusting at the local scale, we observe that thrusting in the foreland is a long-wavelength feature occurring between Lake Geneva and Salzburg. This coincides with the geometry and dynamics of the attached lithospheric slab at depth. Thus, thrusting in the foreland is at least partly linked to changes in slab dynamics.

This study investigates Cenozoic deformation during cooling and exhumation of the Tauern metamorphic and structural dome, Eastern Alps, through Th–Pb dating of fissure monazite-(Ce). Fissure (or hydrothermal) monazite-(Ce) typically crystallizes in a temperature range of 400–200 °C. Three major episodes of monazite growth occurred at approximately 21, 17, and 12 Ma, corroborating previous crystallization and cooling ages.

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.

Metamorphic domes are areas in a mountain chain that were unburied and where deeper parts of the crust rose to the surface. The Lepontine Dome in the Swiss and Italian Alps is such a place, and it is additionally bordered on two sides by shear zones where crustal blocks moved past each other. To determine when these tectonic movements happened, we measured the ages of monazite crystals that form in fluid-filled pockets inside the rocks during these movements of exhumation and deformation.

The Aar and Mont Blanc regions in the Alps are large granitoid massifs characterized by high topography. We analyse when these granitoids were first exhumed to the surface. We test this by tracking specific garnet grains, which are exclusively found in the granitoid massifs, in the sediments contained in the alpine foreland basin. This research ties in with ongoing debates on the timing and mechanisms of mountain building.

Based on own and published age data, we can infer tectonic pulses along-strike the entire northern rim of the Central Alps between 12–4 million years. Although lithologic variations largely influence the local deformation pattern, the tectonic signal is remarkably consistent all the way from Lake Geneva to Salzburg. This might result from a deep-seated tectonic force and marks a change from dominantly vertical to large-scale horizontal tectonics in the late stage of Alpine orogeny.

We studied porosity changes of slates from eastern Switzerland, which were deposited in an ocean in front of the emerging Alps during the Cenozoic. The Alpine collision between the European and African plates brought the rocks from this basin to today’s position in the Alps. From the basin to the surface, the porosity first decreased down to a small number of round cavities (<1 vol%) to microfractures, and once at the surface, the porosity increased again due to the formation of macro-fractures.

Continental high-pressure terranes in orogens offer insight into deep recycling and transformation processes that occur in subduction zones. These remain poorly understood, and currently debated ideas need testing. We document complex garnet zoning in eclogitic mica schists from the Sesia Zone (western Italian Alps). These retain evidence of two orogenic cycles and provide detailed insight into resorption, growth, and diffusion processes induced by fluid pulses under high-pressure conditions.

Subducted continental terranes commonly comprise an assembly of subunits that reflect the different tectono-metamorphic histories they experienced in the subduction zone. Our challenge is to unravel how, when, and in which part of the subduction zone these subunits were juxtaposed. Our study documents when and in what conditions re-equilibration took place. Results constrain the main stages of mineral growth and deformation, associated with fluid influx that occurred in the subduction channel.

Structural 3-D modelling has become a widely used technique within applied projects. We performed a typical modelling workflow for a study site with the occurrence of an underground facility. This exceptional setting enabled us to test the surface-based extrapolation of faults with the mapped faults underground. We estimated the extrapolation-related uncertainty with probabilistic 2-D interpolation. This research was conducted to improve structural 3-D modelling in less-constrained areas.

In the Liaodong Peninsula, the widely exposed Jurassic high-Sr / Y rocks are generally considered to be derived from the thickened mafic crust. However, research on the Zhoujiapuzi granite in this study shows that there is at least one pluton with a high Sr / Y signature inherited from the source. Zircon growth in Zhoujiapuzi granite can be divided into two stages. The light-CL core was formed in a deeper, hotter magma chamber. The dark-CL rim formed from later, more evolved magma.

Here, we conducted spectroscopic measurements on high-pressure, high-temperature fluids and melts to study how halogens, in particular bromine, can be incorporated in subduction zone fluids and melts. We find that a gradual evolution of bromine speciation with liquid composition enables the incorporation of high amounts of Br in both phases. Thus, bromine and, by extension, chlorine are expected to be efficiently recycled from the slab towards the volcanic arc.

The occurrence of boninite in the northern Zambales ophiolite is reported. Boninite is a relatively rare high-magnesium andesite that is intimately associated with early arc volcanism and the initiation of subduction zones. Taken as a whole, the geological and geochemical characteristics of Zambales and Izu-Ogasawara–Mariana forearc volcanic sequences enables a refined geodynamic reconstruction of subduction initiation.

Short summary
This work studies the interplay of epidote dissolution–precipitation and quartz dynamic recrystallization during viscous granular flow in a deforming epidote–quartz vein. Pb and Sr isotope data indicate that epidote dissolution–precipitation is mediated by internal/recycled fluids with an additional external fluid component. Microstructures and geochemical data show that the epidote material is redistributed and chemically homogenized within the deforming vein via a dynamic granular fluid pump.
This work studies the interplay of epidote dissolution–precipitation and quartz dynamic...
