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: In this study, thermomechanical numerical models were used to simulate the formation and evolution of divergent continental margins since continental rifting, taking into account surface processes of erosion. The results showed that the degree of crust-mantle coupling, erosion of the coastal landscape, and preexistence of weakness zones in the continental crust are important factors controlling the reactivation of faults along divergent margins during the postrift phase. The experiments also indicated that the presence of a lower crust with low viscosity contributes to the development and/or reactivation of normal faults in the interior of the continent when subjected to differential denudation and flexural response of the lithosphere. The study suggests that a decoupled continental lithosphere, escarpment retreat due to erosion, and preexisting shear zones parallel to the coast played a role in the development of Cenozoic tectonism in southeastern Brazil.

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: Continental rifts, such as the Songliao Basin in NE China, are influenced by both shallow and deeper processes related to the dynamics of the mantle. The evolution of the Songliao rift volcanism during the Cretaceous can be divided into five stages dominated by crystal fractionation. The magmas originated from a veined asthenospheric mantle and a metasomatized sub-continental lithospheric mantle, suggesting a subduction-related rift caused by the eastward rollback of the Paleo-Pacific slab.

Summary: This study provides a new tectonic map focusing on the extensional style associated with the formation of the Tyrrhenian back-arc basin. Through basin-wide analysis and seismic data interpretation, the evolution of extensional faults, horst and graben structures, and crustal-scale processes in the basin are better understood. The distribution of faults and variation in extensional styles are explored in relation to shallow deformation and crustal processes.

Summary: The Gulf of Mexico is an intraplate oceanic basin with a complex tectonic evolution, involving multiple rifting phases, variable magmatism, and salt deposition. This study presents new insights into the crustal types and tectonic framework of the Florida margin. The results suggest improvements to the plate model of the Gulf of Mexico by considering the polyphase nature of rifting, the rotation of the Yucatan block, and the increase in magmatic supply.

Summary: The Gulf of Mexico started as a continental rift during the Late Triassic-Mid Jurassic period, covered by the Louann Salt, and later split by oceanic crust. Variations in rifted continental crust width and horizontal extension values were observed along the Florida-Yucatan conjugate margins, being larger in the northern margin. The region evolved from early rift with magmatism to a magma-poor margin, with continental break-up involving mantle exhumation and magmatism in specific areas.

Summary: In this study, the mobility of supra-salt sequences in salt-detached gravity-gliding/spreading systems was examined using regional 3D seismic data. Two structural domains were identified in the study area: a highly obstructed domain and a highly mobile domain. Large-scale downslope translation was recorded in the mobile domain, while translation was impeded in the obstructed domain. The study highlights the importance of characterizing domains based on base-of-salt geometry and supra-canopy minibasin configuration for understanding subsidence and downslope translation histories.

Summary: The interaction between crustal thickening and surface processes plays a key role in the growth of continent-continent collision orogens. Internal crustal loading and lithospheric pull are the main factors controlling large scale evolution, while surface process efficiency influences foreland-basin filling and orogen core exhumation. Inherited structures, surface processes, and decoupling between thin-and thick-skinned deformation affect structural style during orogenic growth.

Summary: This study utilizes physical models to investigate thin-skinned regional shortening in salt-influenced basins with isolated minibasins, finding that the volume and distribution of salt prior to shortening are key controls, salt flow leads to tilting and rotation of minibasins, and different processes contribute to the deformation of minibasins during regional shortening. Our findings provide insights into the geometry and kinematics of shortened salt basins and the tectono-stratigraphic evolution of minibasins.

Summary: The configuration of salt deposition has a fundamental influence on deformation in the south-central Pyrenees. By dividing the region into three domains, it was found that the Northern and Southern Domains have complex Mesozoic growth histories, while the Central Domain is simpler. Physical models confirmed that preexisting salt structures could generate specific patterns observed in the Southern Domain.

Summary: The study identifies seven mechanisms by which mobile shales can pierce their roofs, with the dominant mechanism being injection up fractures and faults. Different mechanisms are at play depending on shale viscosity, depth, and proximity to the surface. Although there are common piercement mechanisms between shale tectonics and salt tectonics, resulting structures are often different due to differences in viscosity. The rapid extrusion of mobile shales reaching the surface can lead to caldera collapse of underlying shale chambers, indicating long-term stable growth of passive shale diapirs is unlikely.

Summary: Subduction of aseismic ridges and flat slab subduction play important roles in Cordilleran orogenesis, enhancing rock uplift and exhumation in the overriding plate. Distinguishing between these drivers is possible in the Peruvian flat slab subduction zone, where the interactions between aseismic ridges and flat slab subduction can be assessed.
