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 investigates the post-rift geomorphic evolution in an Elevated Passive Continental Margin lacking a sharp escarpment, focusing on exploring topographic rejuvenation and links with potential controls such as the arrangement of pre-existing structures and lithological variability. The results show post-Miocene topographic rejuvenation and brittle deformation driven by accumulation of far-field stresses in pre-existing weakness zones, indicating that post-rift topographic rejuvenation in an EPCM is not necessarily linked to the formation or persistence of a Great Escarpment.

Summary: Submarine landslides are a common geohazard in the marine environment, with higher densities observed in the proximal regions of the south and southwest margins off west and southwest Iberia. The size range of landslides is inversely proportional to their spacing and frequency, with stronger correlations between 2D and 3D parameters such as area and volume. The relationships between parameters vary across different geomorphological domains, with correlation values influenced by seafloor geomorphology.

Summary: Temporal variations of rare earth elements (REE), major elements, Pb, and Hg were studied in two multicores collected in the Cascais submarine canyon, showing a mixture of Tagus estuarine and marine sediments with patterns influenced by an abandoned chemical complex and preferential diagenetic remobilization of LREE relative to HREE in deeper sites. The influence of diagenetic processes in the REE signal and dispersion of anthropogenic components from the estuary through the canyon were observed.

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 paper studies the Miocene gravity flow deposits in the Lower Congo-Congo Fan Basin, documenting the sequence stratigraphic framework, depositional characteristics, and controlling factors of the gravity flow system. The Miocene is divided into four 3rd-order sequences, mainly comprised of siliciclastic rock and pelite, with distinct sedimentary units formed during different stages. The evolution of the gravity flow deposits is influenced by climate cooling, sea level changes, tectonic uplifting, and salt structures activities.

Summary: The composition and thickness of the crust in the southern Central Andes have a significant impact on contemporary deformation processes. A thicker, denser lithosphere beneath the northern part of the foreland has favored a strong coupling between the South American and Nazca plates, resulting in the development of a sub-horizontal slab.

Summary: Research indicates that the formation of the plateau in the North Patagonian Massif (NPM) area in Argentina was caused by a mantle heating event during the Paleogene, leading to lithospheric uplift. The plateau is still isostatically buoyant and the lithosphere is cooling, yet to reach thermodynamic equilibrium.

Summary: Emerging evidence suggests that U-Pb and Lu-Hf ages of sedimentary apatite group minerals are often younger than their biostratigraphic ages. However, U-Pb dating of exquisitely preserved carbonate fluorapatite (CFA) is rare. Here, researchers used laser-ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) to study the U-Pb ages of CFA minerals in phosphate-rich sediments from the Upper Cretaceous/Paleogene marine sedimentary rocks of the Moroccan High Atlas. The U-Pb dating results indicate that the CFA grains are more than 15 million years younger than their biostratigraphic age. The study also provides insights into the sedimentary and seawater history from which the CFA minerals formed.
