Short summary
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.

Our study examines erosion in a small, pre-Alpine basin by using cosmogenic nuclides in river sediments. Based on a dense measuring network we were able to distinguish two main zones: an upper zone with slow erosion of surface material, and a steeper, lower zone where faster erosion is driven by landslides. The data suggests that sediment has been constantly produced over thousands of years, indicating a stable, long-term balance between contrasting erosion processes.

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.

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.

Overdeepenings are bedrock depressions filled with sediment. We combine the results of a gravity survey with drilling data to explore the morphology of such a depression beneath the city of Bern. We find that the target overdeepening comprises two basins >200 m deep. They are separated by a bedrock riegel that itself is cut by narrow canyons up to 150 m deep. We postulate that these structures formed underneath a glacier, where erosion by subglacial meltwater caused the formation of the canyons.

The Bohemian Massif is one of several low mountain ranges in Europe, which rises more than 1 km above the surrounding lowlands. Landscape characteristics indicate relief rejuvenation due to recent surface uplift. To constrain the pace of relief formation we determined erosion rates of 20 catchments that range from 22 to 51 m per million years. Correlating these rates with topographic properties reveals that contrasts in bedrock erodibility represent a critical control of landscape evolution.

This study investigates how Earth's geodynamic processes shaped the NW Zagros mountain belt in the Middle East. The Neogene foreland basin underwent subsidence due to the load of the surface and the subducting slab and was later influenced by the Neotethys horizontal slab tearing and the associated asthenospheric mantle flow during the Late Miocene and onward.

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

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.

Recession models (RM) are crucial for observing the low flow behavior of a catchment. We developed two novel RM, which are designed to represent slowly draining catchment conditions. With a newly designed low flow prediction procedure we tested the prediction capability of these two models and three others from literature. One of our novel products delivered the best results, because it best represents the slowly draining catchment conditions.

We analysed data from the Illgraben debris flow monitoring station, Switzerland, and we modelled these flows with a debris flow runout model. We found that no correlation exists between the grain size distribution, the mineralogical composition of the matrix, and the debris flow properties. The flow properties rather appear to be determined by the flow volume, from which most other parameters can be derived.

Engineering structures known as check dams are built with the intention of managing streams. The effectiveness of such structures can be expressed by quantifying the reduction of the sediment flux after their implementation. In this contribution, we estimate and compare the volumes of sediment transported in a mountain stream for engineered and non-engineered conditions. We found that without check dams the mean sediment flux would be ca. 10 times larger in comparison with the current situation.

We use apatite (U-Th-Sm)/He thermochronologic on detrital grains sampled from a well to unravel the exhumation history of the northern Swiss Molasse Basin and reconcile seemingly contradicting previous studies. With single grain ages and provenance ages, we achieve to narrowly constrain exhumation magnitude and timing and embed previous results into a single consistent thermal history. This includes proof for hydrothermal activity and a contribution to the discussion on exhumation drivers.

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.

Grain size data are important for studying and managing rivers, but they are difficult to obtain in the field. Therefore, methods have been developed that use images from small and remotely piloted aircraft. However, uncertainty in grain size data from such image-based products is understudied. Here we present a new way of uncertainty estimation that includes fully modeled errors. We use this technique to assess the effect of several image acquisition aspects on grain size uncertainty.

We investigated the origin of glacial sediments in the Bern area to determine their route of transport either with the Aare Glacier or the Valais Glacier. These two ice streams are known to have joined in the Bern area during the last major glaciation (ca. 20 000 years ago). However, little is known about the ice streams prior to this last glaciation. Here we collected evidence that during a glaciation about 250 000 years ago the Aare Glacier dominated the area as documented in the deposits.

Our work is focused on describing how and why the terrace levels of central Amazonia were formed during the last 100 000 years. We propose to address this question through a landscape evolution numerical model. Our results show that terrace levels at lower elevation were established in response to dry–wet climate changes and the older terrace levels at higher elevations most likely formed in response to a previously higher elevation of the regional base level.

Muon tomography is a technology that is used often in geoscientific research. The know-how of data analysis is, however, still possessed by physicists who developed this technology. This article aims at providing geoscientists with the necessary tools to perform their own analyses. We hope that a lower threshold to enter the field of muon tomography will allow more geoscientists to engage with muon tomography. SMAUG is set up in a modular way to allow for its own modules to work in between.

A scientific drilling was conducted into a bedrock trough (overdeepening) in Bern-Bümpliz (Switzerland) in an effort to advance the knowledge of the Quaternary prior to 150 000 years ago. We encountered a 208.5 m-thick succession of loose sediments (gravel, sand and mud) in the retrieved core and identified two major sedimentary sequences (A: lower, B: upper). The sedimentary suite records two glacial advances and the subsequent filling of a lake sometime between 300 000 and 200 000 years ago.

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.

As continental plates collide, mountain belts grow. This study investigated the provenance of rocks from the northwestern segment of the Zagros mountain belt to unravel the convergence history of the Arabian and Eurasian plates. Provenance data synthesis and field relationships suggest that the Zagros Mountains developed as a result of the oceanic crust emplacement on the Arabian continental plate, followed by the Arabia–Eurasia collision and later uplift of the broader region.

The thermal evolution of the East European Platform is reconstructed by means of thermal maturity and low-temperature thermochronometry. Results showed that major heating occurred before the Permian, with maximum paleotemperatures in the earliest and latest Carboniferous for Baltic–Podlasie and Lublin basins, respectively. The Mesozoic thermal history was characterized by gradual cooling from peak temperatures at the transition from Triassic to Jurassic due to decreasing heat flow.

Our knowledge of the geological history of mountain belts relies strongly on thermochronometers, methods that reconstruct the temperature history of rocks found in mountain belts. Here we provide a new equation that describes the motion of rocks in a simplified, wedge-shaped representation of a mountain belt. The equation can be used to interpret thermochronometers and can help quantify the deformation, uplift and erosion history of mountain belts.

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).

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 present new U–Pb age data to provide insights into the source of sediment for the Molasse Sedimentary Basin in Switzerland. The paper aims to help shed light on the processes that built the Central Alpine Mountains between ~35 and ~15 Ma. A primary conclusion drawn from the results is that at ~21 Ma there was a significant change in the sediment sources for the basin. We feel this change indicates major tectonic changes within the Central Alps.

We calculated the probability of sediment transport in coarse-grained mountainous streams in the Alps and the Andes where data on water discharge is available. We find a positive correlation between the predicted probability of sediment transport and the grain size sorting of the bed material. We suggest that besides sediment discharge, the bedload sorting exerts a significant influence on the mobility of sediment and thus on the stability of gravel bars in mountainous streams.

The controls on the 20 Myr old Burdigalian transgression in the Swiss Molasse basin have been related to a reduction in sediment flux, a rise in global sea level, or tectonic processes in the adjacent Alps. Here, we readdress this problem and extract stratigraphic signals from the Upper Marine Molasse deposits in Switzerland. In conclusion, we consider rollback tectonics to be the main driving force controlling the transgression, which is related to a deepening and widening of the basin.

We use drones to study surface geometries of massively dilatant faults (MDFs) in Iceland, with apertures up to tens of meters at the surface. Based on throw, aperture and structures, we define three geometrically different endmembers of the surface expression of MDFs and show that they belong to one continuum. The transition between the endmembers is fluent and can change at one fault over short distances, implying less distinct control of deeper structures on surface geometries than expected.

Using state-of-the-art geomorphic techniques, we quantified a 2-order of magnitude discrepancy between annual, decadal, and millennial sediment fluxes of a landslide-affected mountainous river catchment in the Swiss Alps. Our results illustrate that the impact of a single sediment pulse is strongly attenuated at larger spatial and temporal scales by sediment transport. The accumulation of multiple sediment pulses has rather a measurable impact on the regional pattern of sediment fluxes.

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.

The Mesozoic sequences of the Oman mountains experienced only weak post-obduction overprint and deformation, and thus they offer a unique natural laboratory to study obduction. We present a study of pressure and temperature evolution in the passive continental margin under the Oman Ophiolite using numerical basin models calibrated with thermal maturity data, fluid-inclusion thermometry, and low-temperature thermochronology.

Muon tomography is a technology, similar to X-ray tomography, to image the interior of an object, including geologically interesting ones. In this work, we examined the influence of rock composition on the physical measurements, and the possible error that is made by assuming a too-simplistic rock model. We performed numerical simulations for a more realistic rock model and found that beyond 300 m of rock, the composition starts to play a significant role and has to be accounted for.

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.

Clast imbrication, which is a depositional fabric where clasts overlap each other similar to a run of toppled dominoes, is one of the most conspicuous sedimentary structures in coarse-grained fluvial deposits. However, the conditions leading to this fabric have been contested. Here, we calculate the hydrological conditions for various stream gradients. We find that clast imbrication most likely forms where channel gradients exceed a threshold and where upper flow regime conditions prevail.

The marbles of the migmatitic dome on the island Naxos contain deformed layers of amphibolite with multiple phases of boudinage. The boudins formed by E–W shortening normal to the layers and layer parallel extension in various directions. We identified five different generations of boudins that show that E–W shortening is the prevalent deformation in these rocks during the peak metamorphosis and the following cooling, different from other parts of the island dominated by top-to-north shearing.

We explore the signal of a warmer climate in the suspended-sediment dynamics of a regulated and human-impacted Alpine catchment. We demonstrate that temperature-driven enhanced melting of glaciers, which occurred in the mid-1980s, played a dominant role in suspended sediment concentration rise, through increased runoff from sediment-rich proglacial areas, increased contribution of sediment-rich meltwater, and increased sediment supply in proglacial areas due to glacier recession.

This work aims at understanding the behaviour of an earth flow located in the Swiss Alps by reconstructing very accurately its topography over a 2-year period. Aerial photos taken from a drone, which are then processed using a computer vision algorithm, were used to derive the topographic datasets. Combination and careful interpretation of high-resolution topographic analyses reveal the internal mechanisms of the earthflow and its complex rotational structure, which is evolving over time.

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.

We vary the angle between joints and a rigid basement fault and analyze interpreted map-view photographs at maximum displacement for various parameters and compare to nature. Results show a clear effect of increasing angle between joints and faults on fault geometry, fracture density and connectivity. These information can help interpreting fractured layers in the subsurface.

This paper considers the influence of lithology on the landscape development in the Central Swiss Alps. In high-alpine settings such as the upper Rhône valley, external forcing by climate, glaciation and uplift affects the geomorphological evolution of the landscape. By careful compilation of published data and geomorphological analysis we found that the rock type and its susceptibility to erosion are the main factors controlling the response time to those perturbations.

Cut-fill terraces are common landforms throughout the world. Their distribution both in space and time is not clear-cut, as they can arise from numerous processes. We apply a climate-dependent regolith production algorithm to determine potential sediment loads during climate shifts. When combined with transport capacity, our results suggest that the cut-fill terraces of western Peru can result from transient stripping of hillslope sediment but not steady-state hillslope erosion.

We address the transition between the Paleozoic Variscan and Alpine Mesozoic–Cenozoic cycles using tectono-stratigraphy and thermochronology. This transition unfolds through a multi-phase rifting history. An initial rifting stage occurred in the early Permian, followed in the early–middle Permian by a phase of transcurrent tectonics. This was succeeded by a period of erosion/non-deposition in the middle Permian. Crustal stretching in the Middle Triassic marked the onset of the Alpine cycle.

Subduction zones feature a large elevation difference between the deep oceanic trench and the high mountains on land, which causes stress in the upper plate. We investigate how the topographic stress affects the aftershock seismicity of large subduction earthquakes using analytical and numerical stress models. We show that topographic stress has a large influence on aftershock seismicity and promoted most of the seismicity after the Tohoku-Oki (Japan) and Maule (Chile) earthquakes.

Obtaining reliable estimates of the subsurface state distributions is essential to determine the location of, e.g., potential nuclear waste disposal sites. However, providing these is challenging since it requires solving the problem numerous times, yielding high computational cost. To overcome this, we use a physics-based machine learning method to construct surrogate models. We demonstrate how it produces physics-preserving predictions, which differentiates it from purely data-driven approaches.

We postulate that the observed spatial distribution of large earthquakes in active convergence zones, organised in segments where large events are repeated every 100–300 years, depends on large-scale continental faults and fluid release from the subducting slab. In order to support this model, we use proxies at different spatial and temporal scales (historic seismicity, megathrust slip solutions, inter-seismic cumulative seismicity, GPS/viscous plate coupling, and coastline morphology).

Finally, we propose an original seismic cycle model that is mainly driven by the southward migration of the Ionian slab roll-back.

Alpine tectonic inversion is reviewed for southwestern Iberia, known for its historical earthquakes and tsunamis. High-quality 2D seismic data image 26 faults mapped to a depth exceeding 10 km. Normal faults accommodated important vertical uplift and shortening. They are 100–250 km long and may generate earthquakes with Mw > 8.0. Regions of Late Mesozoic magmatism comprise thickened, harder crust, forming lateral buttresses to compression and promoting the development of fold-and-thrust belts.

When a continent is pulled apart, it breaks and forms a series of depressions called rift basins. These basins lie above weakened crust that is then subject to intense deformation during subsequent tectonic compression. Our analogue experiments show that when a system of basins is squeezed in a direction perpendicular to the main trend of the basins, some basins rise up to form mountains while others do not.

Laboratory experiments allow us to simulate these large-scale processes, highlighting the links between rotational plate motion and the overall development of the EARS. These insights are relevant when studying other rift systems around the globe as well.

A magnetic fabric analysis provides information about the reorientation of magnetic grains and is applied to three sandbox models that simulate different stages of basin inversion. The analysed magnetic fabrics reflect the different developed structures and provide insights into the different deformed stages of basin inversion.

Continental crust comprises bodies of varying strength, formed through numerous tectonic events. When subject to extension, these areas produce distinct rift and fault systems. We use 3D models to examine how rifts form above
strongand
weakareas of crust. We find that faults become more developed in weak areas. Faults are initially stopped at the boundaries with stronger areas before eventually breaking through. We relate our model observations to rift systems globally.

We study the construction of the Ukrainian Carpathians with LT thermochronology (AFT, AHe, and ZHe) and stratigraphic analysis. QTQt thermal models are combined with burial diagrams to retrieve the timing and magnitude of sedimentary burial, tectonic burial, and subsequent exhumation of the wedge's nappes from 34 to ∼12 Ma. Out-of-sequence thrusting and sediment recycling during wedge building are also identified. This elucidates the evolution of a typical wedge in a roll-back subduction zone.

When a sedimentary basin is subjected to compressional tectonic forces after its formation, it may be inverted. A thorough understanding of such
basin inversionis of great importance for scientific, societal, and economic reasons, and analogue tectonic models form a key part of our efforts to study these processes. We review the advances in the field of basin inversion modelling, showing how the modelling results can be applied, and we identify promising venues for future research.

Shales are identified as suitable caprock formations for geolocigal CO2 storage thanks to their low permeability. Here, small-sized shale samples are studied under field-representative conditions with X-ray tomography. The geochemical impact of CO2 on calcite-rich zones is for the first time visualised, the role of pre-existing micro-fissures in the CO2 invasion trapping in the matererial is highlighted, and the initiation of micro-cracks when in contact with anhydrous CO2 is demonstrated.

The Slyne Basin is a sedimentary basin located offshore north-western Ireland. It formed through a long and complex evolution involving distinct periods of extension. The basin is subdivided into smaller basins, separated by deep structures related to the ancient Caledonian mountain-building event. These deep structures influence the shape of the basin as it evolves in a relatively unique way, where early faults follow these deep structures, but later faults do not.

Under tectonic forces, the upper part of the crust can break along different types of faults, depending on the orientation of the applied stresses. Using scaled analogue models, we show that the relative magnitude of compressional and extensional forces as well as the presence of inherited structures resulting from previous stages of deformation control the location and type of faults. Our results gives insights into the tectonic evolution of areas showing complex patterns of deformation.

Old seismic data recently reprocessed with modern software allowed us to study at depth the Late Cretaceous tectonic structures in the Permo-Mesozoic rock sequences in the Sudetes. The structures formed in response to Iberia collision with continental Europe. The NE–SW compression undulated the crystalline basement top and produced folds, faults and joints in the sedimentary cover. Our results are of importance for regional geology and in prospecting for deep thermal waters.

Reactivation of tectonic faults can lead to earthquakes and jeopardize underground operations. The reactivation potential is linked to fault properties and the tectonic stress field. We create 3D geometries for major faults in Germany and use stress data from a 3D geomechanical–numerical model to calculate their reactivation potential and compare it to seismic events. The reactivation potential in general is highest for NNE–SSW- and NW–SE-striking faults and strongly depends on the fault dip.

Earthquake extent prediction is limited by our poor understanding of slip deficit patterns. From a mechanical analysis applied along the Chilean margin, we show that earthquakes are bounded by extensive plate interface deformation. This deformation promotes stress build-up, leading to earthquake nucleation; earthquakes then propagate along smoothed fault planes and are stopped by heterogeneously distributed deformation. Slip deficit patterns reflect the spatial distribution of this deformation.

We studied the Gioia Sannitica normal fault (GF) within the southern Matese fault system (SMF) in southern Apennines (Italy). It is a fault with a long slip history that has experienced recent reactivation or acceleration. Present activity has resulted in late Quaternary fault scarps and Holocene surface faulting. The maximum slip rate is ~ 0.5 mm/yr. Activation of the 11.5 km GF or the entire 30 km SMF can produce up to M 6.2 or M 6.8 earthquakes, respectively.

Rare earth elements (REEs) are considered critical mineral resources for future industrial growth due to their short supply and rising demand. This study applied an artificial-intelligence-based technique to target potential REE-deposit hosting areas in western Rajasthan, India. Uncertainties associated with the prospective targets were also estimated to aid decision-making. The presented workflow can be applied to similar regions elsewhere to locate potential zones of REE mineralisation.

The Pollino region is a highly seismic area of Italy. Increasing the geological knowledge on areas like this contributes to reducing risk and saving lives. We reconstruct the 3D model of the faults which generated the 2010–2014 seismicity integrating geological and seismological data. Appropriate relationships based on the dimensions of the activated faults suggest that they did not fully discharge their seismic potential and could release further significant earthquakes in the near future.

Molasse deposits, deposited and deformed at the western Alpine front during the Miocene (23 to 5.6 Ma), record the chronology of that deformation. We combine the first precise chronostratigraphy (precision of ∼0.5 Ma) of the Miocene molasse, the reappraisal of the regional structure, and the analysis of growth deformation structures in order to document three tectonic phases and the precise chronology of thrust westward propagation during the second one involving the Belledonne basal thrust.

New images from the multi-national AlpArray experiment illuminate the Alps from below. They indicate thick European mantle descending beneath the Alps and forming blobs that are mostly detached from the Alps above. In contrast, the Adriatic mantle in the Alps is much thinner. This difference helps explain the rugged mountains and the abundance of subducted and exhumed units at the core of the Alps. The blobs are stretched remnants of old ocean and its margins that reach down to at least 410 km.

In this paper, we dated fault movements at geological timescales which uplifted the sedimentary successions of the Jura Mountains from below the sea level up to Earth's surface. To do so, we applied the novel technique of U–Pb geochronology on calcite mineralizations that precipitated on fault surfaces during times of tectonic activity. Our results document a time frame of the tectonic evolution of the Jura Mountains and provide new insight into the broad geological history of the Western Alps.

As continental plates collide, mountain belts grow. This study investigated the provenance of rocks from the northwestern segment of the Zagros mountain belt to unravel the convergence history of the Arabian and Eurasian plates. Provenance data synthesis and field relationships suggest that the Zagros Mountains developed as a result of the oceanic crust emplacement on the Arabian continental plate, followed by the Arabia–Eurasia collision and later uplift of the broader region.

Central western Europe underwent a strange episode of lithospheric deformation, resulting in a chain of small mountains that run almost west–east across the continent and that formed in the middle of a tectonic plate, not at its edges as is usually expected. Associated with these mountains, in particular the Harz in central Germany, are marine basins contemporaneous with the mountain growth. We explain how those basins came to be as a result of the mountains bending the adjacent plate.

Several large strike-slip faults in western Slovenia are known to be active, but most of them have not produced strong earthquakes in historical times. In this study we use geomorphology, near-surface geophysics, and fault excavations to show that two of these faults had surface-rupturing earthquakes during the Holocene. Instrumental and historical seismicity data do not capture the strongest events in this area.

A new analogue modelling approach was used to simulate the influence of tectonic extension and tilting of the basin floor on salt tectonics in rift basins. Our results show that downward salt flow and gravity gliding takes place if the flanks of the rift basin are tilted. Thus, extension occurs at the basin margins, which is compensated for by reduced extension and later by shortening in the graben centre. These outcomes improve the reconstruction of salt-related structures in rift basins.

We have analysed the role of deep salt layers during tectonic shortening of a group of sedimentary basins buried below the North Sea. Due to the ability of salt to flow over geological timescales, the salt layers are much weaker than the surrounding rocks during tectonic deformation. Therefore, complex structures formed mainly where salt was present in our study area. Our results align with findings from other basins and experiments, underlining the importance of salt tectonics.

We used laboratory experiments to simulate the early evolution of rift systems, and the influence of structural weaknesses left over from previous tectonic events that can localize new deformation. We find that the orientation and type of such weaknesses can induce complex structures with different orientations during a single phase of rifting, instead of requiring multiple rifting phases. These findings provide a strong incentive to reassess the tectonic history of various natural examples.

Although viscosity of the crust largely exceeds that of magmas, we show, based on the Aegean and Tyrrhenian Miocene syn-kinematic plutons, how the intrusion of granites in extensional contexts is controlled by crustal deformation, from magmatic stage to cold mylonites. We show that a simple numerical setup with partial melting in the lower crust in an extensional context leads to the formation of metamorphic core complexes and low-angle detachments reproducing the observed evolution of plutons.

Constraining the conditions at which rocks form is crucial for understanding geologic processes. For years, the conditions under which rocks from Syros, Greece, formed have remained enigmatic; yet these rocks are fundamental for understanding processes occurring at the interface between colliding tectonic plates (subduction zones). Here, we constrain conditions under which these rocks formed and show they were transported to the surface adjacent to the down-going (subducting) tectonic plate.

Short summary
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.
Based on thermochronological data, we infer thrusting along-strike the northern rim of the...
