Summary: Climate-triggered fluctuations of surface masses can influence the stress state and slip behavior of faults in continental rifts. Lakes developed within these rifts can modulate the stress states and slip rates of rift border faults and intrarift faults. This study provides insights into the relationship between climate-driven surface mass variations and the subsurface stress state of fault planes and associated seismic potentials.

Summary: The study utilized crustal scale physical models to investigate multiphase rifting, simulating the structures formed in rift zones during different extension phases. It was found that faults formed during early extension phases play a crucial role in controlling the development of structures in later rift phases. The amount of extension during the initial phase is critical in determining the prominence and reactivation potential of pre-existing faults in later stages of rifting.

Summary: The study examines the scaling relationship between fault length and displacement in the central Kenya Rift, revealing a power law distribution for fault length and displacement data in different fault zones. The results suggest a trend of strain localization onto larger faults as the fault system evolves, with varying fault orientations contributing to strain accommodation along the rift. The fractal dimension of cumulative distribution of fault size populations can be used to deduce patterns of fault growth and evolution.

Summary: The three-dimensional evolution of normal faults is investigated using a combination of seismic reflection and well data. Segmentation characteristics of geometry and displacement distribution are observed along strike and dip oriented directions. The fault surfaces can be divided into different areas corresponding to different tectonic evolution stages. The segmentation in the lower part of the fault is caused by the intersection of faults with different strikes, while the segmentation in the upper part is the result of lateral growth and linkage of overlapping fault segments.

Summary: The study of the late Mesozoic-Cenozoic tectono-stratigraphic evolution of the northern Lofoten-Vesteralen margin offshore northern Norway was conducted using a combination of 2D multi-channel seismic profiles, 3D seismic survey, and potential field and well data. The analysis revealed distinct along-margin basin segmentation, with five main rift phases and eight mapped fault families identified, as well as compressional deformation features related to volcanic build-up and doming of Cenozoic successions. The study highlighted the essential nature of the northern Lofoten-Vesteralen margin in understanding the tectono-stratigraphic evolution of the NE Atlantic margins.

Summary: This study investigates the segmentation and strain accommodation along the Bilila-Mtakataka Fault (BMF) system in the Southern Malawi Rift. By integrating surface and subsurface data, the researchers reveal the discrepancy between the surface segmentation, fault offset, and long-term throw of the BMF. They also observe different geological characteristics in different segments of the fault. The study suggests that the BMF may continue to accumulate strain and pose a significant seismic hazard in the region.

Summary: A remarkable outcrop of an extensional NW-oriented horst block exists at the Akheider-El Ramliya fault block (ARFB) in the Gulf of Suez rift. The field geological mapping identifies the architecture, linkage style, and evolution of the normal fault system at the ARFB. The results reveal various geometries of normal fault interaction and the formation of relay zones between boundary faults. Two sub-basins with syn-rift sediments are recognized at the downthrows of the border faults. The study provides insights into the structural characteristics and controls on syn-sedimentation in the northern Gulf of Suez rift.

Summary: The early stages of normal fault growth in the Zomba Graben have been investigated through field observations. The study provides insights into the displacement of active border and intrarift faults, as well as the extent of fault damage and mineralisation associated with their surface exposures. The results suggest that the Zomba border fault has a wider fault zone compared to the intrarift faults, with greater fault damage and mineral alteration. The research findings also highlight the rapid lengthening of normal faults in the area, despite their low displacement.

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: The lithofacies analyses of carbonate deposits from the Mayran Formation in northeast Mexico revealed variability in carbonate lithofacies controlled by hydrological conditions, sediment inputs, and climate. The presence of different components in the lacustrine carbonates, along with isotopic compositions, indicated deposition in freshwater lakes with in situ carbonate production. The overall facies variability was driven by inherited basin geomorphology, accommodation, basin hydrology, and ultimately climate.

Summary: The deposition of classic turbidites is traditionally thought to be a continuous process of sediment accumulation by a gradually waning turbidity current. However, through numerical simulations and rock-record examples, it has been shown that the depositional event involves many brief periods of nondeposition due to hydraulic fluctuations driven by interfacial Kelvin-Helmholtz waves. This suggests that the stratigraphic record of sedimentation may be incomplete even at the scale of a single turbidite.

Summary: The delivery of coarse siliciclastic sediment to deep-water environments in active rift basins is influenced by tectonics, climate, eustasy, hinterland geology, and shelf processes. The stratigraphic records of deep-water syn-rift basin-fills reflect changes in palaeoenvironment, while a constrained record of climatic fluctuations in the hinterland source area in deep-water deposits is rare. The study in the Corinth Rift integrates core samples and outcrop exposures to reconstruct palaeoenvironmental changes and compare them to global climate records.

Summary: This study uses a numerical modeling approach to investigate the topographic evolution, erosion and basin stratigraphy during single and multi-phase rifting. The results show that the drainage network undergoes dynamic evolution in response to fault growth and linkage, as well as depocenter overfilling and overspilling. There are profound differences between topographic and depocenter development during single and multi-phase rifting, with implications for sedimentary facies architecture.

Summary: Basement highs are an important sediment source in continental rifts and rifted margins, but the back-tilted footwall dip slopes of these highs have been less studied. We investigate a case study from the Norwegian continental shelf, where sedimentary systems preserved on a dip slope provide insights into the evolution of the Froya High.
