Summary: The internal zones of the Western Alps arc are derived from the subduction of the Adria plate during its northward drift in the Paleogene. The exhumation of these zones started in the early Oligocene due to the westward extrusion of the Adria plate. The fold-and-thrust structures in these zones follow an arc shape and postdate the initial nappe stacking.

Summary: The research data suggests that the location and shape of the Pamir plateau may be caused by the forceful indentation of the Indian mantle lithosphere, resulting in complex interactions with the Asian slab. The Indian mantle indenter may lead to the delamination and overturning of the Asian slab, while also affecting the lithosphere of the Tarim basin.

Summary: This study reveals the contribution of frontal thrust slip to tsunami generation by modeling seafloor deformation using fault-bend folding theory. The results show that frontal thrust slip generates lower tsunami energies compared to slip on the down-dip decollement, indicating that slip on the down-dip decollement plays a dominant role in the tsunami generation process of tsunami earthquakes.

Summary: This paper explores the process of Indian continental lithosphere underthrusting and uplifting Tibet, and outlines the paleogeographic and geodynamic consequences of pre-Miocene models. By kinematically restoring the initial horizontal underthrusting, it accurately predicts the diachronous slab break-off and unlocks the Miocene of Himalaya-Tibet as a natural laboratory for unsubductable lithosphere convergence. Additionally, the paper discusses three different paleogeographic scenarios and their corresponding challenges and opportunities.

Summary: A doublet earthquake event occurred on 1 July 2022 in the Zagros fold-and-thrust belt in southeast Iran, involving two main shocks with a magnitude larger than M-w 6.0. The InSAR deformation field revealed significant surface uplift caused by fault-related folding in the seismic zone. The preferred faulting model suggests that higher dip angle and overlying gentle dipping faults were responsible for the two main shocks, with the first main shock triggering the second one.

Summary: This study presents a descriptive model of the Sabzevar Oceanic Basin (SOB) in Northeast Iran, based on detailed geological evidence and reconstruction of its evolutionary geologic history. The evidence suggests that the SOB formed during Late Triassic-Early Jurassic times as a result of extensional movements following the subduction initiation of the Iranian sector of the NeoTethys in the Zagros orogenic belt and closed in the Paleocene after NeoTethyan early continental collision. The magmatic activity in the SOB shows a progressive spatio-temporal evolution with distinct ranges of magma series.

Summary: The Banda arcs in eastern Indonesia are formed by the interaction of the Sunda, Philippine Sea, and Australia plates, with the influence of the breakup of Gondwana. The metamorphic rocks of Timor have mixed Gondwanan and SE Asian affinities.

Summary: The depositional and metamorphic history of the mylonitic meta-sedimentary rocks in Huanan, near the central Jiamusi Block, was studied to understand the tectonic implications. The rocks were deposited in the Late Triassic and experienced high-pressure/low-temperature metamorphism before the Early Jurassic. The accretionary complexes dispersedly exposed throughout NE China may represent post-exhumation thrusting or remnants of archipelagic oceanic crusts.

Summary: The study reveals that the varying scales of veins in the (ultra-) high pressure metamorphic belt of Southwestern Tianshan orogen, China, reflect complex mass transfer processes in subduction zones, which are crucial for understanding arc magma characteristics.

Summary: The study reveals that the kinematic paths of internal shear zones are influenced by multiple factors, with immediate footwall structures playing a key role in the evolution of shear zones. Shear zones tend to evolve progressively from simple shear domination to pure shear domination, with shear zones having higher pure shear components recording higher strain. Additionally, there is variation along the strike in the kinematic paths of shear zones due to the changing geometries of immediate footwall structures.

Summary: Compression during normal continental-oceanic subduction leads to the development of a rugose subduction wedge landward of the trench within the marine forearc. Second order subduction events can disrupt these processes over several millions of years and elicit depositional responses that are discordant within the forearc stratigraphy. The synchronicity, long-term cyclicity and regional extent of these stratigraphic changes indicate that regional tectonism underpinned deposition.

Summary: The closure mechanism of Nenjiang Ocean (NJO) in the Great Xing'an Range area is a controversial scientific issue. The newly discovered Yinder Complex is a typical subduction-accretionary related mélange. The deformation stages in the complex indicate collisional compression and postcollisional stretching strike-slip of the Xing'an Accretionary Terrane (XAT) and Songnen Block (SNB) respectively, with the early and late stage lineations corresponding to these deformations.
