Ichnological discrimination of hemipelagic‐dominated slope versus basin‐floor mudstones: Insights from early Viséan successions of a distally steepened ramp, northern Iran

The Depositional Record, Volume 11, Issue 5, Page 1563-1595, November 2025.
This study integrates sedimentological and ichnological data to reveal the depositional processes and environmental conditions of deep‐water muddy gravity flows in the Mobarak Formation. It highlights distinct ichnocoenoses and bioturbation patterns, offering insights into basin‐floor versus slope mudstones and their implications for hydrocarbon ...

Architecture of North Atlantic contourite drifts modified by transient circulation of the Icelandic mantle plume [PDF]

, 2015
Overflow of Northern Component Water, the precursor of North Atlantic Deep Water, appears to have varied during Neogene times. It has been suggested that this variation is moderated by transient behavior of the Icelandic mantle plume, which has ...

Stad Slide: Preconditioning and failure of one of the world's largest megaslides

Journal of Quaternary Science, Volume 40, Issue 8, Page 1392-1406, November 2025.
ABSTRACT Submarine landslides can generate tsunamis and pose risks to underwater infrastructure, but a lack of direct observations of such slides hinders our understanding of their development and hazard potential. Studying the morphology of past slides can offer insights into their preconditioning and failure.

Glacial-interglacial sedimentation control on gas seepage exemplified by Vestnesa Ridge off NW Svalbard margin

Frontiers in Earth Science
Vestnesa Ridge is built-up of thick contourites mainly deposited during the last ∼5 million years. Methane leaks from deep gas reservoirs creating pockmarks on its crest, and which have been the focus of numerous studies.

Mode of Continental Thinning and Breakup Along the North Iberian‐Armorican Conjugate Margins in the Bay of Biscay

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 10, October 2025.
Abstract Continental breakup involves multiple extension styles; each linked to unique structural and sedimentary processes. High‐angle, low‐angle, listric and antilistric normal faults develop at different stages and positions during rifting. The Bay of Biscay and its margins, a prototypical example of magma‐poor rifted margins during Jurassic ...

Role of tectonic stress in seepage evolution along the gas hydrate‐charged Vestnesa Ridge, Fram Strait [PDF]

, 2015
Methane expulsion from the world ocean floor is a broadly observed phenomenon known to be episodic. Yet the processes that modulate seepage remain elusive.

Thousands of cold-water coral mounds along the Moroccan Atlantic continental margin : distribution and morphometry [PDF]

, 2019
Coral mounds formed by framework-forming cold-water corals pierce the seabed along most continental margins of the Atlantic Ocean and new sites are continuously being discovered.

A Paleotectonic Atlas of the African Plate: Permian to Recent

Journal of Petroleum Geology, Volume 48, Issue 4, Page 231-279, October 2025.
ABSTRACT The fragmentary release of petroleum data defining the deep structure and stratigraphy of African basins has been integrated with existing literature to compile 19 tectonic maps over key geological intervals from Permian to Recent times. African plate margins range in their age of opening from Late Triassic (off Lebanon), through Early/Middle ...

Early Jurassic extrinsic solar system dynamics versus intrinsic Earth processes: Toarcian sedimentation and benthic life in deep-sea contourite drift facies, Cardigan Bay Basin, UK

Progress in Earth and Planetary Science
The Cardigan Bay Basin (UK) may have functioned as a deep and narrow strait, and thereby influenced Early Jurassic oceanic circulation through the northern and southern Laurasian Seaway, and between Boreal and Peri-Tethys domains.
