Beyond the Bulk: Magnetic Property Variations With Sediment Grain Size. Insights Into Process and Provenance

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 1, January 2026.
Abstract Bulk (whole sample) magnetic properties of three‐hundred‐sixty‐two samples from five North Atlantic Ocean sediment cores are compared to the magnetic properties of five grain‐size fractions separated from the same samples. The relative abundance and magnetic properties of the size fractions are highly variable both within a core and among ...

Dropstones in the Mar del Plata Canyon Area (SW Atlantic): Evidence for Provenance, Transport, Distribution, and Oceanographic Implications

Geochemistry, Geophysics, Geosystems, 2021
A variety of gravel‐ to cobble‐sized rocks, recovered from the Mar del Plata (MdP) Canyon area (Western South Atlantic at 38°S) and interpreted as ice‐rafted debris, represent the first evidence that large icebergs have floated in the Falkland (Malvinas)

The age and origin of the central Scotia Sea [PDF]

, 2010
Opening of the Drake Passage gateway between the Pacific and Atlantic oceans has been linked in various ways to Cenozoic climate changes. From the oceanic floor of Drake Passage, the largest of the remaining uncertainties in understanding this opening is

Dynamic Controls on Salt Structures and Translation Velocity at Continental Rifted Margins

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 1, January 2026.
Abstract Salt tectonics at rifted margins involves intricate interactions between weak, viscous evaporite layers and brittle sedimentary rocks. Geophysical data and geological interpretation offer valuable insights into evaporite structure formation and the average translation rate of evaporite and sediment layers on time scales of several million ...

Cyclic Pockmark Formation Linked to Plio‐Pleistocene Sea‐Level Rise on the Chatham Rise, New Zealand

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 12, December 2025.
Abstract Pockmarks are geomorphological depressions on the seafloor in various underwater environmental settings. They are commonly linked to fluid release from subsurface reservoirs; however, the processes involved, fluid types, and relative timing of their formation often remain enigmatic.

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 ...

Sandy contourite drift in the late Miocene Rifian Corridor (Morocco):Reconstruction of depositional environments in a foreland-basin seaway [PDF]

, 2017
The Rifian Corridor was a seaway between the Atlantic Ocean and the Mediterranean Sea during the late Miocene. The seaway progressively closed, leading to the Messinian Salinity Crisis in the Mediterranean Sea. Despite the key palaeogeographic importance

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 ...
