Summary: The identification of soft-sediment deformation structures is complex due to the possibility of different processes producing similar structures. Interpreting the origin of these structures requires detailed sedimentological study and knowledge of the depositional environment and stratigraphic evolution. Seismic shock is one possible cause, but there are other triggering mechanisms as well.

Summary: The study on the late Permian-Triassic sedimentary successions in the Central Qiangtang metamorphic belt reveals valuable information about the tectonic environment and associated structures of trench-slope basins. Through a multidisciplinary approach, it is found that these sedimentary successions were mainly deposited during the northward subduction of the Longmu Co-Shuanghu Tethys Ocean beneath the North Qiangtang block, showing regional spatiotemporal variations and providing new insights into the geological evolution of trench-slope basins as well as ancient analogs characterized by extensional tectonism.

Summary: The Galabre catchment, part of the French network of critical zone observatories, was instrumented in 2007 to study suspended sediments dynamics in areas with highly erodible badlands on different lithologies. The site includes meteorological stations, gauging stations, and automatic water sampling systems to quantify sediment fluxes and analyze the links between meteorological forcing and watershed hydrosedimentary response. The measurements were extended to the dissolved phase in 2017 to understand water origin during events and the partitioning between particulate and dissolved fluxes of solutes in the critical zone.

Summary: Salt structures can provide valuable insights into tectonic and depositional processes due to their distinct responses. However, previous studies have not systematically identified, mapped, or classified the evolution of multi-stage salt structures in a regional context. The Southern North Sea, with its abundant 3D seismic data, offers a unique opportunity to investigate the evolution of salt structures. Our study used a comprehensive seismic dataset and analyzed the time-thickness variations around salt structures to examine their evolution across different sub-basins. We found that multi-stage salt diapirs in the Southern North Sea developed through three regional phases and up to five local stages.

Summary: The Bressanone pluton in the Southalpine region shows evidence of new Oligocene magmatic activity, overlapping with the age of the widespread calc-alkaline magmatism, supporting the hypothesis of fluid release during the main stage of Alpine orogenic magmatism.

Summary: Low-angle normal faults (LANFs) are the main structures in the central Southern Alps area of Northern Italy, and they are in contact with the Upper Carboniferous-Permian volcanic-sedimentary succession. Tourmalinites, which are likely of metasomatic origin, frequently replace former cataclasites along LANFs. LANFs, together with high-angle faults, controlled the opening of the Permian Orobic Basin and were potential pathways for hydrothermal fluids. Furthermore, the same fluids may have played a role in the formation of Uranium ore deposits.

Summary: In this study, a crustal scale model for the Neo-Tethys margin in the Northern Calcareous Alps was obtained by restoring regional cross-sections of carbonate platforms. The thermal evolution of the margin was modeled and a detailed timeline for the evolution was established. The study suggests that salt-floored carbonate platforms can be used to characterize the margin's evolution.

Summary: Examining the links between tectonics and climate, this study finds that temperature-controlled erosion processes at 1,500-2,000 meters above sea level can play a greater role in modulating erosion than precipitation or glaciation. These temperature-controlled erosional processes may be efficient enough to balance the fastest rock-uplift rates on Earth, contributing to the link between tectonics and climate.

Summary: The western Qaidam Basin in NE Tibet contains numerous NW-SE-trending thrusts along the Altyn Tagh Fault and north of the Kunlun Range. A 2-Myr-long disturbance record from a core drilled on a thrust-cored anticline reveals episodic local deformation and varying tectonic strain rates in the region. The study suggests that during seismic clusters, regional deformation is more concentrated in the fold-and-thrust system rather than regional major strike-slip faults.

Summary: In the Henan Province of southern North China, the lower Taiyuan Formation from the late Pennsylvanian to early Permian was studied to constrain the amplitude of sea level variations. Three facies associations were identified and four transgression-regression cycles were revealed. Based on detrital zircon provenance data, the sea-level rise in southern North China during this time period was estimated to be between 16 and 32 m, which is consistent with previous studies and modelled sea-level variations.

Summary: A large number of siliceous mounds in the upper part of the Permian Teresina Formation in the Paraná Basin, Brazil are identified as hot springs. These mounds show remarkable features indicating a hydrothermal origin. The study provides important insights into the formation of syn-depositional hydrothermally precipitated silica in ancient sedimentary basins.

Summary: The Dorgali Formation in eastern Sardinia consists of dolomitized oolitic grainstone and exhibits a complex diagenetic history. Petrographic examinations revealed three main phases of dolomites with different crystal sizes, indicating the origin of dolomites in different burial conditions and temperatures. The geochemical characteristics of dolomitizing fluids suggest a seawater origin for the parent fluids.

Summary: This contribution demonstrates the pre-Miocene dextral activity of the Great Kavir - Doruneh Fault System (GKDFS) in Central Iran, with the Arusan Fault System (AFS) showing important dextral shearing. The study indicates that deformation occurred in a total simple shear regime, with enormous Meso-Cenozoic dextral displacements along the AFS and GKDFS attested by significant offsets of the Paleotethys suture zone.

Summary: The study reveals the complexity of the sedimentary architecture of channelized turbidites and identifies the factors that influence their evolution. The results show that the channel-levee complex underwent three stages of evolution, including changes in sedimentary facies and architectural style. This highlights the interplay between sediment input, slope equilibrium profile, and channel morphodynamics.

Summary: This petrographic database was created to study the Oligocene-Langhian succession of the Arquata Scrivia area in NW Italy, which includes different marine sedimentary units deposited in the Tertiary Piedmont Basin. The database provides unique information about the petrographic composition of the studied succession, which had not been previously investigated. Petrographic analysis was conducted on samples collected from different parts of each sedimentary unit using a polarized-light microscope. The collected data are presented in quartzfeldspar-lithic ternary plots and can serve as a starting point for future analyses to understand the evolution of the basin on a larger scale.

Summary: This study examines the timing and evolution of Cretaceous successions in the Central-Eastern Iran Microplate (CEIM) and Sanandaj-Sirjan Zone (SSZ). The study finds that the Cretaceous marine transgression occurred almost simultaneously on a levelled topography, indicating a previous deep erosion. Additionally, the stratigraphic evolution of the three studied areas reflects changes in depositional environments, suggesting different subsidence rates.
