Bottom-simulating reflector dynamics at Arctic thermogenic gas provinces: An example from Vestnesa Ridge, offshore west Svalbard [PDF]

, 2017
The Vestnesa Ridge comprises a >100 km long sediment drift located between the western continental slope of Svalbard and the Arctic mid-ocean ridges. It hosts a deep water (>1000 m) gas hydrate and associated seafloor seepage system.

Geophysical Insights Into 3D Crustal Architecture of Jurassic Magmatic Intrusions in the Moroccan Atlas

Earth and Space Science, Volume 12, Issue 12, December 2025.
Abstract Magmatic intrusions in rifted continental margins play a critical role in shaping structural evolution, yet their geometry and emplacement mechanisms remain poorly constrained in salt‐influenced terrains. The Moroccan Central High Atlas, a segment of the Atlas fold‐and‐thrust belt, hosts extensive Middle Jurassic to Early Cretaceous intrusions

The Northern Calcareous Alps revisited: Formation of a hyperextended margin and mantle exhumation in the Northern Calcareous Alps sector of the Neo-Tethys (Eastern Alps, Austria) [PDF]

, 2023
The Neo-Tethys margin evolution is preserved in the Northern Calcareous Alps (Eastern Alps), from Late Permian crustal stretching to Late Triassic oceanization.

Interplay Between Salt Tectonics and a Large Igneous Province in the Espírito Santo Basin (Brazil)

Tectonics, Volume 44, Issue 11, November 2025.
Abstract Salt tectonics provinces host numerous resources and are now targeted as potential areas of development for energy storage capacities such as underground storage in salt caverns. Sedimentary basins containing salt structures are common at passive margins where volcanic rocks, emplaced either during the lithospheric breakup or the post‐rift ...

Surging Versus Continuous Turbidity Currents: Flow Dynamics and Deposits in an Experimental Intraslope Minibasin [PDF]

, 2004
Small intraslope basins (~100 km^2), or "minibasins," such as those found on the continental slope of the Gulf of Mexico, have been filled predominantly by turbidity currents.

Shale Tectonics in the Hyperextended Continental Margin of the Niger Delta

Tectonics, Volume 44, Issue 7, July 2025.
Abstract Based on the interpretation of a large seismic data set, we provide a comprehensive description of the structures affecting the entire Niger Delta, from the onshore domain to the deep‐offshore. The shale‐dominated delta lies on a divergent segment of the west African passive margin.

Magnitude of rift-related burial and orogenic contraction in the Marrakech High Atlas revealed by zircon (U-Th)/He thermochronology and thermal modelling [PDF]

, 2016
The Atlas of Morocco is a continental rift developed during the Triassic-Jurassic and moderately inverted during the Cenozoic. The High Atlas south of Marrakech, with exposures of basement and Triassic early synrift deposits, has been viewed as a high ...

Petrochronology of Alkaline Intrusive Magmatism in the Central High‐Atlas (Morocco) and Relationships With Jurassic Salt Diapirism

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 6, June 2025.
Abstract A striking feature of the Imilchil alkaline province, in the Moroccan Central High Atlas, is the close association of magmatic intrusions with Triassic sediments exhumed by diapirism. This study reports field, petrographic, geochemical and Sr‐Nd isotopic data, as well as new U‐Pb zircon ages, which allow us to constrain the timing of the ...

Salt Diapirs and Minibasins Along a Transect Across the Basque‐Cantabrian Pyrenees: Implications for Cover‐Basement Interaction During Rifting and Inversion

Tectonics, Volume 44, Issue 5, May 2025.
Abstract The Basque‐Cantabrian Pyrenees experienced Early Cretaceous rifting and latest Cretaceous to Cenozoic inversion, with the presence of prerift Upper Triassic Keuper salt influencing how deformation was accommodated. Considerable disagreement exists on the degree of decoupling of supra‐ and subsalt deformation, the amount of thin‐skinned ...

Pockmark Occurrence in the Northern Gulf of Mexico Influenced by Glacial Cycles and Hydrate Stability

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 4, April 2025.
Abstract On the continental slope of the northern Gulf of Mexico, pockmarks concentrate near the estimated updip edge of the hydrate stability zone (HSZ). We identified 5,691 pockmarks in the northern Gulf of Mexico by combining existing records with manually mapped pockmarks from bathymetric data.
