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 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).

Our study investigates the statistical relationship between geological fractures and earthquakes in the southwestern Swiss Alps. We analyze how the fracture size and earthquake rupture are related and find differences in how fractures at different depths rupture seismically. While shallow fractures tend to rupture only partially, deeper fractures are more likely to rupture along their entire length, potentially resulting in larger earthquakes.

Carbonate rocks can control how strong the Earth’s crust is in places. They are often described in simple terms as calcite or dolomite, but they are more complicated. At the atomistic level different amounts of elements, like magnesium and calcium, are incorporated at different temperatures and at the microscopic level carbonates can have different internal structures. We review 50 years of experimental data to provide equations that can describe the strength of most kinds of carbonates.

During the Middle Miocene, the Earth transitioned from a warm to a colder period, significantly impacting ecosystems and climate. We present a 23–13 Ma climate record of soil carbonates from a northern Mediterranean basin. We propose that rapid temperature shifts in our data result from changes in atmospheric circulation patterns. Our climate record aligns well with contemporaneous terrestrial European and global marine records, enhancing our understanding of Miocene climate dynamics.

C4 grassland expansion during Late Miocene Cooling caused profound global ecosystem changes. However, C4 biomass expansion in western Eurasia is poorly documented. Our δ13C record shows the simultaneous Late Miocene emergence of C4 vegetation in Anatolia and S Asia. However, Anatolia is the only region on Earth where C4 biomass largely disappeared during the Early Pliocene. We suggest a warm-to-cold season shift in rainfall led to C3 biomass return and impacted large mammal populations.

To date, there remains a deficiency in rheological parameters for polymineralic rocks to be used in models for strain localization and seismicity in the Earth's continental middle crust. We calculated grain size and stress sensitivity of experimentally deformed natural, fine-grained, granitoid rocks. Extrapolation of these parameters predicts a switch in the weakest material as a function of grain size and deformation mechanism: from coarse monomineralic quartz to fine polymineralic rocks.

Rheology of polymineralic rocks is crucial to unravel the strain and stress distribution in Earth’s middle crust with implications for e.g. seismicity or geothermal systems. Our experimental study of the viscous rheology of natural, fine-grained, granitoid rocks shows that dissolution-precipitation creep and pinning is active in extremely weak narrow zones. Due to the polymineralic character, strain localizes with and without a precursory fracture in zones weaker than monomineralic quartz.

We study the use of zircons as dosimeters using modern techniques, highlighting their advantages such as time-invariant dose rates. We explore the correlation between zircon geochemistry and luminescence properties, observe fast zircon optically stimulated luminescence (OSL) bleaching rates, and assess the potential of auto-regeneration. Low OSL sensitivities require combining natural OSL and auto-regenerated thermoluminescence (TL), with the potential to enhance age accuracy and precision.

Seven million years ago, the marine gateway connecting the Mediterranean Sea with the Atlantic Ocean started to close, and, as a result, water circulation ceased. To find out how this phenomenon affected the fish living in the Mediterranean Sea, we examined the changes in the isotopic composition of otoliths of two common fish species. Although the species living at the surface fared pretty well, the bottom-water fish starved and eventually became extinct in the Mediterranean.

We present model-based topographic sensitivity experiments that provide valuable constraints for interpreting past proxies and records of climate and tectonic processes. The study uses a climate model to quantify the response of regional climate and oxygen isotopic composition of precipitation to diachronous surface uplift scenarios across the European Alps. The results suggest that isotopic signal changes can be measured in geologic archives using stable isotope paleoaltimetry.

We describe different carbon isotope excursions (CIEs) in an upper Paleocene to lower Eocene lignite succession (Schöningen, DE). The combination with a new stratigraphic framework allows for a correlation of distinct CIEs with long- and short-term thermal events of the last natural greenhouse period on Earth. Furthermore, changes in the peat-forming wetland vegetation are correlated with a CIE that can be can be related to the Paleocene–Eocene Thermal Maximum (PETM).

Here we present new surface elevation constraints for the middle Miocene Central Alps based on stable and clumped isotope geochemical analyses. Our reconstructed paleoelevation estimate is supported by isotope-enabled paleoclimate simulations and indicates that the Miocene Central Alps were characterized by a heterogeneous and spatially transient topography with high elevations locally exceeding 4000 m.

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.

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.

Short summary
We used U–Pb dating and Pb–Sr–O–H isotopes of hydrothermal epidote to characterize fluid circulation in the Aar Massif (central Swiss Alps). Our data support the hypothesis that Permian fluids exploited syn-rift extensional faults. In the Miocene during the Alpine orogeny, fluid sources were meteoric, sedimentary, and/or metamorphic water. Likely, Miocene shear zones were exploited for fluid circulation, with implications for the Sr isotope budget of the granitoids.
