Geology of the Central High Atlas diapiric province (Rich-Imilchil): a cartographic synthesis

Journal of Maps
We present a geological map of the Central High Atlas of Morocco (excluding the mountain fronts), illustrating a structure consisting of narrow ridges of lower Jurassic carbonates, occasionally cored by Triassic Keuper rocks and basalt, or by mid-late ...

Post‐Miocene Transtensional Opening of the Northern Red Sea

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 7, July 2026.
Abstract The mechanism of opening, as well as the crustal characteristics of the northern Red Sea are subject of ongoing controversial scientific debate. With the objective of elucidating the nature of rifting in this area, a grid of 2D multi‐channel reflection seismic data was acquired off the Al Wajh carbonate platform (AWCP), and supplemented by ...

Diapiric ridges and minibasins in the Central High Atlas: impact on geometries and facies distribution (Lower-Middle Jurassic, Morocco)

BSGF - Earth Sciences Bulletin
The Central High Atlas of Morocco is the result of the Alpine tectonic inversion of an intracontinental Mesozoic basin, the infill of which started with thick Upper Triassic clay and evaporite deposition.

Spatial and Temporal Distribution of Salt‐ and Shale‐Detached Contractional Deformation, Mexican Northwestern Gulf of Mexico

Tectonics, Volume 45, Issue 7, July 2026.
Abstract In the northwestern Gulf of Mexico, gravity‐driven contractional deformation is recorded across the Salina del Bravo, the Perdido and Peripheral fold belts, and the Mexican Cordilleras. Integrating seismic interpretation, structural mapping, and analysis, we examine the spatial and temporal partitioning of shortening above three principal ...

Structural Evolution of a Polyphase Salt‐Tectonic System From Syn‐Rift Extension to Syn‐Orogenic Deformation in the Middle Atlas (Oum Er Rbia Region, Morocco)

Tectonics, Volume 45, Issue 7, July 2026.
Abstract Salt tectonics has received little attention in the Middle Atlas, despite the widespread occurrence of Triassic evaporites and their potential to exert first‐order control on basin architecture and deformation. This study presents the first integrated analysis of polyphase salt tectonics in the Middle Atlas, focusing on the Oum Er‐Rbia sector,

Pockmarks, Mud Volcanoes and Hydrocarbon Seeps in the Northern Gulf of Mexico: Trends and Controls on Widespread Fluid and Gas Venting

Basin Research, Volume 38, Issue 2, March–April 2026.
Basin‐scale dataset reveals widespread hydrocarbon venting at the seafloor in the northern Gulf of Mexico. Hydrocarbon release at the seafloor is related to the occurrence of the underlying Louann salt and the gas hydrate stability zone. ABSTRACT The release of hydrocarbons, pore water and fluidized sediments impacts seafloor morphology, marine ...

Gravity tectonics controls on reservoir-scale sandbodies: Insights from 3D seismic geomorphology of the canyons buried in the upper slope of the Eastern Niger delta basin

Energy Geoscience
High-resolution 3D seismic data analysis was integrated with a calibrated well and biostratigraphy data to present the first overview of a buried Pleistocene canyon system on the upper slope of the eastern Niger Delta, the Galabor Canyon.

Stress and Rock Failure Near Salt Bodies: Insights From Field Observations, Kinematic Modeling, and Mechanical Analysis Near Arches National Park, Paradox Basin, Utah

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 2, February 2026.
Abstract Salt's inherent weakness and capacity for ductile deformation create significant mechanical contrasts that locally perturb the stress field in surrounding rocks, often leading to deviations from regional tectonic stresses. Variations in local stress are a critical factor for wellbore stability, seal integrity, and fluid flow in subsurface ...

Deformation and evolution of Aptian salt tectonics in the central Lower Congo Basin: integrated analogue and 3D discrete element modelling

Frontiers in Earth Science
The Lower Congo Basin, a salt-rich passive-margin basin, displays complex coupling between salt tectonics and sedimentation that strongly controls hydrocarbon systems, yet the deformation mechanisms and spatiotemporal evolution of its Aptian salt ...

Experimental Verification of a Two‐Dimensional Inverse Method for Turbidity Currents Using a Deep Neural Network

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 1, February 2026.
Abstract Turbidites have been widely studied as indicators of the occurrences and magnitudes of paleo‐tsunamis and paleo‐earthquakes. Inversion to estimate flow conditions from turbidites offers valuable insights into the magnitudes of paleo‐seismic and tsunami events.
