Summary: This study systematically tested the influence of salt basin geometry on salt tectonics through analogue experiments, showing that the initial salt depocenter location and mean salt thickness are dominant factors controlling deformation. The experiments were qualitatively analyzed using top view photography, and quantitatively through Particle Image Velocimetry (PIV) and 3D photogrammetry (Structure-from-Motion, SfM) to obtain surface displacement and topographic evolution.

Summary: This study reports on the structural geometry and stacking sequence of an Archean Alpine-style sub-horizontal fold/thrust nappe pile in northern China, providing a quantitative basis for studying the tectonism style during Archean orogenesis. The nappe pile is subdivided into different nappes with major ductile shear zones at their bases, and they originated from different tectonic belts of an ancient paleo-ocean before being emplaced. The study reveals similarities between the Archean Zanhuang nappes and other orogenic belts, supporting the existence of horizontal plate tectonics in the Archean.

Summary: Based on marine geological research milestones, the late Jurassic Campeche salt basin in the southern Gulf of Mexico is related to the late Middle Miocene to Recent geological structures. The study reconstructed the geometry of the top of the Paleozoic basement and base-salt topography using shipborne magnetic data and 28,612 km of pre-stack, depth-migrated, 2D seismic data. The Campeche segment of the Gulf of Mexico outer marginal trough, which is 40-55 km wide, marks the limit of the northwest-directed passive margin foldbelt.

Summary: This study investigates the distribution and composition of salt layers in the Slyne and Erris basins offshore west of Ireland, unveiling their role in structural evolution. The research provides a framework for understanding halokinetic structures in other basins on the Irish Atlantic margin and offers insights into the Permian and Triassic palaeogeography of the region. The study also has broader implications for the evolution of salt-related structures in rift basins with multiple stratigraphically discrete salt layers.

Summary: Base-salt relief drives complex deformation patterns in the mid-slope domain of salt-bearing passive margins, influencing the evolution of salt-related structures. Contraction, extension, and rotation are fundamental processes controlling the structural style in these areas. Through detailed studies of salt structures, we have gained a deeper understanding of these processes.

Summary: In this study, the authors explain several diagnostic structural and sedimentary features that may be used to distinguish pre-orogenic halokinetic structures from shortening-related structures in the Silica Nappe. They also discuss the effects of pre-orogenic salt tectonics on the fold-and-thrust belt evolution.

Summary: Research finds that wide rifted margins are characterized by gravity-driven updip extension and downdip shortening, and syn-depositional salt flow and salt stretching also occur in these margins. The results have significant implications for understanding the genesis and evolution of salt-bearing rifted margins.

Summary: This study investigates the evolution of minibasins and salt walls in passive margin salt basins using a 3D seismic reflection dataset. The findings suggest that the kinematic domains of extension, translation and contraction control minibasin initiation and subsequent evolution, but variations in minibasin geometries can be observed due to along-strike growth and linkage of depocentres. The study also highlights the complexity and variability of minibasin growth compared to existing domain-controlled models.

Summary: This study examines the interaction between evaporites and magma in sedimentary basins, focusing on how it influences salt tectonics and magma emplacement. By analyzing the seismic data from the Santos Basin, the research identifies the timing and spatial relationship of igneous intrusions with thick Aptian salt deposits. The study suggests that the interaction between salt and magma can influence salt tectonics and the distribution of magma plumbing systems, ultimately impacting basin evolution.

Summary: Salt tectonics in the Eastern Persian Gulf, Iran, are associated with the flow of the Hormuz Salt and the Fars Salt layers, which began in the Early Paleozoic and Early Miocene, respectively, due to differential sedimentary loading and subsalt basement faults. Over time, the formation of diapirs and pillows remains unresolved, with significant salt extrusion leading to the development of allochthonous salt sheets and wings. The ascendancy of the Hormuz Salt occurred since the Late Oligocene, while the Fars Salt was mainly driven by differential sedimentary loading.

Summary: The study of salt tectonics at salt-bearing margins reveals differences in the Western Mediterranean Sea compared to other regions, with a clear relationship between salt structures and crustal segmentation. The influence of temperature parameters on salt deformation is suggested to play a significant role in the mechanisms of salt tectonics.

Summary: The Orphan Basin, a Mesozoic rift basin located offshore Eastern Canada, remains poorly understood compared to other rift basins in the North Atlantic region. This review aims to critically analyze and synthesize the available geoscientific information on the basin, identify knowledge gaps, and provide insights for future research directions.

Summary: The study of the Eastern Pilbara craton from 3600 to 2800 Ma suggests that it developed following a typical orogenic sequence, contrary to previous assumptions that it formed in a different planetary dynamics mode. The structural, magmatic, and sedimentological development of the craton resembles that of other well-preserved Eo-Mesoarchean terranes, indicating a common derivation from immature introceanic accretionary orogens during the formation of Earth's first continents.

Summary: The connection between source rock and reservoir separated by salt strata is a global problem. This paper focuses on the No. 5 strike-slip fault passing through salt layers in the Tarim Basin. The seismic data reveals different structural styles in the salt layer, including transpression, transtension, and pure strikeslip. The impact of deep strike-slip salt tectonics on petroleum exploration is discussed using data from seven wells, showing that thicker salt layers result in poorer production.
