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 ...

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.

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 ...

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.

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 ...

Authigenic Uranium Preservation and Bottom Water Oxygenation in the Scotia Sea

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 9, September 2025.
Abstract Sedimentary uranium (U) and thorium (Th) isotopes are invaluable proxies to assess bottom water redox conditions, site‐specific sediment focusing and vertical rain rates. We investigate if authigenic uranium (aU) can serve as a proxy for bottom water ventilation at International Ocean Discovery Program Site U1537 in the Scotia Sea and we ...

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.

Lithostratigraphy of the Neogene succession of the Danish North Sea

GEUS Bulletin
The Neogene of the Danish North Sea is more than 1200 m thick. Despite being penetrated by numerous wells, formal lithostratigraphic subdivision of this succession has previously been restricted to the lowermost part.

From Hydrocarbon to CO2 Storage: Unveiling the Potential of the Miocene Lille John Member in the Danish North Sea

Basin Research, Volume 37, Issue 5, September–October 2025.
Depositional evolution of the upper Miocene complex. ABSTRACT To achieve net‐zero carbon emissions by 2050, gigatonnes of CO2 must be captured and stored in the subsurface. Screening and exploration of prospective storage sites have thus gained momentum in recent years.

Decreased Deep Water Oxygenation in the Western North Pacific During the Plio‐Pleistocene Transition

Geophysical Research Letters, Volume 52, Issue 14, 28 July 2025.
Abstract The deep North Pacific, a vast respired carbon reservoir, likely plays a key role in the Plio‐Pleistocene CO2 decline and global cooling, but evidence for this is lacking. Here, oxygenation change in the upper deep western North Pacific between 5.3 and 1.0 million years ago (Ma) is reconstructed using multiple organic and inorganic proxies ...
