Summary: The study explored the subsurface structural styles of the Jura fold-and-thrust belt in eastern France by combining geological mapping, cross-section balancing, and 2D-kinematic forward modeling. The results revealed mixed structural styles in the region, with similarities to other fold-and-thrust belts characterized by thick salt-bearing basal detachments and multiple detachment horizons within the sedimentary sequence. The findings can serve as a benchmark for comparing structural styles in similar fold-and-thrust belts.

Summary: By combining structural and microstructural data with stable and clumped isotopes, we characterized the paleofluid circulation in the Jura fold-and-thrust belt, eastern France. We found that syn-tectonic fluid circulation occurred along high permeability networks and was dominated by cold meteoric fluids. The study also suggested the presence of deep fluids from PermoTriassic rocks.

Summary: The pre-existing faults in the mechanical basement play a crucial role in controlling deformation in thin-skinned fold-and-thrust belts. The presence of basement steps leads to deformation localization and influences the evolution of structures. These findings provide insights into the deformation processes of the Earth's crust.

Summary: In this study, the basement depths in the United Arab Emirates' fold-and-thrust belt (FTB) and its associated foreland basins were determined and the relationship between shallow sedimentary structures and deep basement features was investigated. The results showed that thrusts, backthrusts, and folds were observed in the northern portions of the study area, while the Tarabat backthrust dominated the southern region. The 3D gravity inversion results suggested an increase in basement depth and the thickness of late Oligocene-early Miocene successions towards the north, indicating a northward increase in the severity of thrusting and crustal loading along the Khusub thrust. The correlation between basement uplifts and shallower anticlinal features suggested that the basement structures were reactivated during the Late Cretaceous ophiolite obduction and the late Oligocene-early Miocene Zagros collision.

Summary: This study reviews the evolutionary history of drainage patterns in the Qilian Mountains and identifies the transition from transverse-dominated to longitudinal-dominated rivers during mountain building. The study also analyzes the evolutionary trends using topographic metrics and suggests that longitudinal rivers will be captured by transverse rivers. The results validate the evolution model of drainage patterns in active fold-thrust belts and provide insights for investigating drainage network evolution process in other similar belts.

Summary: The surface uplift of salt diapirs in the East Carpathians Bend reveals potential for new hydrocarbon energy resources, and numerical simulations suggest that the observed deformation is likely caused by a relatively small salt diapir rising from a depth of <7 km with a viscosity of 1x10(17) Pa s.

Summary: The study presents a new 2D kinematic forward model for the westernmost Internal Jura fold-and-thrust belt, which provides new insights into its kinematic evolution. The model suggests a pure thin-skinned style dominated by forward stepping deformation and minor back-stepping thrust sequences. Multiple thrust horizons and decollements are found within different layers in the Jura FTB.

Summary: Paleo-uplift amplitude significantly influences salt-related deformations in salt-bearing fold-and thrust belts (FTBs), leading to changes in strain localization and salt distribution. Increasing paleo-uplift amplitude results in stronger effects on deformation propagation and can cause out-of-sequence deformation towards the hinterland.

Summary: The ongoing shortening between the Eurasian and Arabian plates is primarily accommodated within the Zagros Fold-Thrust Belt, but the distribution of active shortening within the belt, particularly in its NW part, is not well constrained. Depositional ages of uplifted river terraces and kinematic modeling were used to calculate long-term slip rates during the Late Pleistocene to Holocene, providing insights into faulting and folding rates in the area. Different slip rates were observed in various faults and folds, with distinct deformation patterns both in the NW and NE parts of the Zagros belt.

Summary: Research shows that there are significant differences in the tectonic activity characteristics and patterns between the thick-skinned fold-and-thrust belt on the eastern flank of the Andean Plateau in northwestern Argentina and the thin-skinned Subandean fold-and-thrust belt of northern Argentina and southern Bolivia. Estimating and comparing deformation rates and patterns across different timescales can provide a better understanding of the deformation processes in these mountain ranges.

Summary: This case study of the Variscan fold-and-thrust belt in SW Sardinia focuses on the lateral and vertical changes in mechanical properties of the stratigraphic succession, and how they relate to previous folding, thrust geometry, and kinematics. The investigation also highlights the close connection between bedding attitudes, back thrust surfaces geometry, shear strength during thrust propagation, and variation in shortening amount in different parts of folds. The study suggests that folding-related mechanical anisotropy may induce ductile deformation in the footwall of back-thrusts, providing insights for fore-thrust development as well.

Summary: This study investigates the age and geochemical variability of volcanic arc rocks found in the Chinese, Kyrgyz, and Tajik North Pamir in Central Asia, revealing a complex volcanic arc system. The findings indicate a later activity of the North Pamir volcanic arc compared to the West Kunlun region, with a more pronounced mantle component, challenging existing models.

Summary: The constant increase of geodetic instrumentation over the past decades enables us to not only detect ever smaller tectonic signals but also to monitor their evolution in time and space. We present spatial and temporal slip variations observed on a fault affected by a large, intermediate-field earthquake: the 2015 M(w)7.2 Sarez, Central Pamir, earthquake ruptured the sinistral, NE-trending Sarez-Karakul fault system.

Summary: The Permo-Triassic period in the Chinese North Pamir is characterized by well-preserved volcano-sedimentary sequences, providing important insights into the geodynamic evolution of Asia's pre-Cimmerian southern margin. Permian volcanism in the region was mainly pyroclastic and mafic to intermediate, while Triassic volcanic activity coincided with major Cimmerian intrusive events to the south. This suggests a complex tectonic history involving subduction, magmatic activity, and back-arc extension in the region.

Summary: The Late Cretaceous intraplate shortening event in central western Europe is associated with marine basins of relatively high amplitude and short wavelength. By using an elastic flexural model conditioned to take account of basement thrusts, the study reproduces many features of the Subhercynian Cretaceous Basin and related basement thrusts, suggesting similarities with larger-scale foreland basins associated with collisional orogens on plate boundaries.

Summary: In the Late Cretaceous, a compressional tectonic event impacted central Europe, with the timing of this event still being debated. By reconstructing the timing of basin reorganization using borehole data and thickness maps, it was found that the start of inversion happened 5 million years earlier than previously assumed. The difficulty in pinpointing the end of the Late Cretaceous compressional event in central Europe is attributed to regional uplift and salt migration affecting the signal of shifting marginal troughs.

Summary: The study investigates the lens-shaped slivers of Permian (Zechstein) amid Triassic units along the master fault of the Sontra Graben in central Germany, revealing a conceptual model involving partial reactivation of the graben's main normal fault and shortcut thrusting during inversion. The results suggest that back-thrusting wedged some Zechstein slivers into incompetent Triassic units, indicating a complex structural history involving both extension and contraction.

Summary: The study reveals that a large part of central Europe experienced uplift in Late Cretaceous to Paleogene time, with thrusting of basement blocks and domal uplift occurring in slightly different time frames. Results suggest that dynamic topography caused by upwelling asthenosphere significantly contributed to the observed pattern of exhumation in central Germany.
