A Paleotectonic Atlas of the African Plate: Permian to Recent

open access: yesJournal 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

open access: yesGeochemistry, 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 ...

Increasing impact of North Atlantic Ocean circulation on sedimentary processes along the passive Galicia Margin (NW Spain) over the past 40 million years

open access: yesFrontiers in Earth Science
Off the Northwestern Iberian Peninsula, the vigorous bottom-current regime interacts with a complex seafloor topography inside the Galicia Interior Basin (GIB), which was tectonically shaped during the opening of the North Atlantic Ocean basin in ...

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

open access: yes, 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.

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

open access: yesBasin 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.

133,000 Years of Sedimentary Record in a Contourite Drift in the Western Alboran Sea: Sediment Sources and Paleocurrent Reconstruction

open access: yesGeosciences, 2019
The Djibouti Ville Drift is part of a contourite depositional system located on the southern side of the Djibouti Ville Seamount in the Alboran Sea (Western Mediterranean).

Contourite vs Turbidite Outcrop and Seismic Architectures

open access: yesAngolan Mineral, Oil & Gas Journal, 2020
The hydrocarbon exploration of oceanic depositional systems demands a better understanding of the role of bottom currents and their implications for petroleum systems such as reservoir and sealing rocks. Deep-marine bottom-current reworked sands (sandy contourites) have been recognized in hydrocarbon-bearing sands of the Kwanza Basin.

Bedform Growth Beneath Periodic Internal Solitary Waves Propagating Through a Tidal Flow

open access: yesJournal of Geophysical Research: Oceans, Volume 130, Issue 8, August 2025.
Abstract Internal solitary waves (ISWs), ubiquitous to lakes and coastal oceans, have often been proposed as a mechanism for generating subaqueous sandwaves. Yet, the physical mechanisms underlying ISW‐driven bedform growth remain poorly understood.

Geochemical Signatures of Paleoclimate Changes in the Sediment Cores from the Gloria and Snorri Drifts (Northwest Atlantic) over the Holocene-Mid Pleistocene

open access: yesGeosciences, 2019
A multiproxy study of the sediment cores taken from the Snorri Drift, formed under the influence of the Iceland−Scotland bottom contour current, and from the Gloria Drift, located southward Greenland at the boundary of Irminger and Labrador Seas ...
