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.

Continental crust comprises bodies of varying strength, formed through numerous tectonic events. When subject to extension these areas produce varying rift and fault systems. We use 3D models to examine how rifts form above ‘strong’ and ‘weak’ areas 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.

Short summary
Continental rifts form by linkage of individual rift segments and disturb the regional stress field. We use analog and numerical models of such rift segment interaction to investigate the linkage of deformation and stresses and subsequent stress deflections from the regional stress pattern. This local stress re-orientation eventually causes rift deflection when multiple rift segments compete for linkage with opposingly propagating segments and may explain rift deflection as observed in nature.

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.

This study investigates one of the key processes that may lead to the destruction and destabilization of continental tectonic plates: the infiltration of buoyant, hot, molten rock (magma) into the base of the plate. Using simple calculations, I suggest that heating during melt–rock interaction may thermally perturb the tectonic plate, weakening it and potentially allowing it to be reshaped from beneath. Geochemical, petrologic, and geologic observations are used to guide model parameters.

Short summary
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.

We constructed a three-dimensional numerical geomechanics model to obtain the continuous slip rates of active faults and crustal velocities in the northeastern Tibetan Plateau. Based on the analysis of the fault kinematics in the study area, we evaluated the possibility of earthquakes occurring in the main faults in the area, and analyzed the crustal deformation mechanism of the northeastern Tibetan Plateau.

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.

We have built a community model for the evolution of the Earth's plate–mantle system. Created with open-source software and an open-access plate model, it covers the last billion years, including the formation, breakup, and dispersal of two supercontinents, as well as the creation and destruction of numerous ocean basins. The model allows us to
seeinto the Earth in 4D and helps us unravel the connections between surface tectonics and the
beating heartof the Earth, its convecting mantle.

In this study we present a method to compute a reference pressure based on density structure in which we cast the problem in terms of a partial differential equation (PDE). We show in the context of 3D models of continental rifting that using the pressure as a boundary condition within the flow problem results in non-cylindrical velocity fields, producing strain localization in the lithosphere along large-scale strike-slip shear zones and allowing the formation and evolution of triple junctions.

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.

Short summary
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.

Legacy 2-D seismic data with newly acquired 3-D seismic data were used to construct a new model of geological evolution of NW Poland over last 400 Myr. It illustrates how the destruction of the Caledonian orogen in the Late Devonian–early Carboniferous led to half-graben formation, how they were inverted in the late Carboniferous, how the study area evolved during the formation of the Permo-Mesozoic Polish Basin and how supra-evaporitic structures were inverted in the Late Cretaceous–Paleogene.

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.

The local topographic slope of an accretionary prism is often used to determine the effective friction on subduction megathrust. We investigate how the brittle–ductile and the smectite–illite transitions affect the topographic slope of an accretionary prism and its internal deformation to provide clues to determine the origin of observed low topographic slopes in subduction zones. We finally discuss their implications in terms of the forearc basin and forearc high genesis and nature.

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.

We present an erosion rate analysis on dated rock and sediment from the Northern Apennine Mountains, Italy, which provides new insights on the pattern of erosion rates through space and time. This analysis shows decreasing erosion through time on the Ligurian side but increasing erosion through time on the Adriatic side. We suggest that the pattern of erosion rates is consistent with the present asymmetric topography in the Northern Apennines, which has likely existed for several million years.

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.

Field trips in the Stratigraphy, Structure, Tectonics (SST) course transitioned to a virtual format in Fall 2020, due to the COVID pandemic. Virtual field experiences (VFEs) were developed in web Google Earth and were evaluated in comparison with on-location field trips via an online survey. Students recognized the value of VFEs for revisiting outcrops and noted improved accessibility for students with disabilities. Potential benefits of hybrid field experiences were also indicated.

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.

Past strong earthquakes can produce topographic deformations, often

Using a ground-penetrating radar (GPR), we unveiled possible buried Quaternary faulting in the Mt. Pollino seismic gap region (southern Italy). We aim to contribute to seismic hazard assessment of an area potentially prone to destructive events as well as promote our workflow in similar contexts around the world.

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.

We combine gravity anomaly and topographic data with observations from thermochronology, metamorphic grades, and the granite inventory to detect patterns of basement block segmentation and differential exhumation along the southwestern Bohemian Massif. Based on our analyses, we introduce a previously unknown tectonic structure termed Cham Fault, which, together with the Pfahl and Danube shear zones, is responsible for the exposure of different crustal levels during late to post-Variscan times.

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.

Knowledge about the stress state in the upper crust is of great importance for many economic and scientific questions. However, our knowledge in Germany is limited since available datasets only provide pointwise, incomplete and heterogeneous information. We present the first 3D geomechanical model that provides a continuous description of the contemporary crustal stress state for Germany.

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.

The influence and interaction of elastic material properties (Young's modulus, Poisson's ratio), density and low-friction faults on the resulting far-field stress pattern in the Earth's crust is tested with generic models. A Young's modulus contrast can lead to a significant stress rotation. Discontinuities with low friction in homogeneous models change the stress pattern only slightly, away from the fault. In addition, active discontinuities are able to compensate stress rotation.

The borders between oceans and continents, called margins, can be convergent, divergent, or horizontally sliding. The formation of oceans occurs in a divergent context. However, some divergent margin structures display an accommodation of horizontal sliding during the opening of oceans. To study and understand how the horizontal sliding part occurring during divergence influences the margin structure, we performed 3D high-resolution numerical models evolving during tens of millions of years.

Moderate to strong earthquakes commonly produce surface faulting, either along the primary fault or as distributed rupture on nearby faults. Hazard assessment for distributed normal faulting is based on empirical relations derived almost 15 years ago. In this study, we derive updated empirical regressions of the probability of distributed faulting as a function of distance from the primary fault, and we propose a conservative scenario to consider the full spectrum of potential rupture.

The former Piemont–Liguria Ocean, which separated Europe from Africa–Adria in the Jurassic, opened as an arm of the central Atlantic. Using plate reconstructions and geodynamic modeling, we show that the ocean reached only 250 km width between Europe and Adria. Moreover, at least 65 % of the lithosphere subducted into the mantle and/or incorporated into the Alps during convergence in Cretaceous and Cenozoic times comprised highly thinned continental crust, while only 35 % was truly oceanic.

The low-relief, mean-elevation Baima Xueshan massif experienced slow exhumation at a rate of 0.01 km/Myr since at least 22 Ma and then regional rock uplift at 0.25 km/Myr since ~10 Ma. The high-relief, high-elevation Kawagebo massif shows much stronger local rock uplift related to the motion along a west-dipping thrust fault, at a rate of 0.45 km/Myr since at least 10 Ma, accelerating to 1.86 km/Myr since 1.6 Ma. Mekong River incision plays a minor role in total exhumation in both massifs.

Earthquake hazard is often specified using instrumental records. However, this record may not accurately forecast the location and magnitude of future earthquakes as it is short (100s of years) relative to their frequency along geologic faults (1000s of years). Here, we describe an approach to assess this hazard using fault maps and GPS data. By applying this to southern Malawi, we find that its faults may host rare (1 in 10 000 years) M 7 earthquakes that pose a risk to its growing population.

We use 2D numerical models to highlight the role of basal drag in subduction force balance. We show that basal drag can significantly affect velocities and evolution in our simulations and suggest an explanation as to why there are no trends in plate velocities with age in the Cenozoic subduction record (which we extracted from recent reconstruction using GPlates). The insights into the role of basal drag will help set up global models of plate dynamics or specific regional subduction models.

Many of the world's hydrocarbon resources are found in rifted sedimentary basins. Some rifts experience multiple phases of extension and inversion. This results in complicated oil and gas generation, migration, and entrapment histories. We present examples of basins in the Western Desert of Egypt and the western Black Sea that were inverted multiple times, sometimes separated by additional phases of extension. We then discuss how these complex deformation histories impact exploration campaigns.

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.

In this paper, we present newly developed numerical models to simulate episodic growth of geological faults.
This growth of faults occurs during the seismic cycle, with spontaneously generated primary and secondary fault structures. With these models we are able to show the evolution of complex fault geometries. Additionally, we can quantify the impact of earthquakes on fault growth.

We study the Iberian plate motion, from the late Permian to middle Cretaceous. During this time interval, two oceanic systems opened. Geological evidence shows that the Iberian domain preserved the propagation of these two rift systems well. We use geological evidence and pre-existing kinematic models to propose a coherent kinematic model of Iberia that considers both the Neotethyan and Atlantic evolutions. Our model shows that the Europe–Iberia plate boundary was made of two rift systems.

We apply three-dimensional (3D) thermo-mechanical numerical simulations of the shortening of the upper crustal region of a passive margin in order to investigate the control of 3D laterally variable inherited structures on fold-and-thrust belt evolution and associated nappe formation. The model is applied to the Helvetic nappe system of the Swiss Alps. Our results show a 3D reconstruction of the first-order tectonic evolution showing the fundamental importance of inherited geological structures.

The Alboran Sea is one of the most active region of the Mediterranean Sea. There, the basin architecture records the effect of the Africa–Eurasia plates convergence. We evidence a Pliocene transpression and a more recent Pleistocene tectonic reorganization. We propose that main driving force of the deformation is the Africa–Eurasia convergence, rather than other geodynamical processes. It highlights the evolution and the geometry of the present-day Africa–Eurasia plate boundary.

Short summary
Due to a thermal insulation effect of oceanic crust, the seafloor heat flux is predicted to be low over young lithosphere (compared to other cooling models). Consequently, the amount of heat extracted from oceanic lithosphere by ventilated hydrothermal circulation is predicted to be significantly lower than previous models. About 50% of total hydrothermal power is extracted on ridge axes.
