Numerical Modeling of Purely Active (Plume‐Produced) Continental Rifting and Break‐Up

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 2, February 2026.
Abstract In contrast to the traditional mechanism of passive continental rifting (driven by far‐field tectonic forces), the active rifting‐to‐break‐up processes (caused by rising mantle plumes) are still poorly understood. However, most episodes of fragmentation of the last supercontinent Pangea were relatively shortly preceded (within ∼10 Myr) by the ...

The mineral and isotopic signatures of glacially eroded sediments exported from Hudson Strait to the Labrador Sea during Hudson Strait Heinrich events H0 to H4

Journal of Quaternary Science, Volume 41, Issue 1, Page 4-24, January 2026.
ABSTRACT The sediment signature of glacial erosion products exported from Hudson Strait to the Labrador Sea during Hudson Strait Heinrich (HS‐H) events is evaluated using four distinct proxies: paired δ18Ο and δ13C data on the carbonate fraction, εNd and U–Pb isotopes in the silicate fraction, the mineral composition of the <2 mm bulk sediment fraction,

Rifting Evolution of the Central Campos Basin as a Hybrid Rifted Margin: Insights From Tectonic and Magmatic Structures

Tectonics, Volume 45, Issue 1, January 2026.
Abstract Recent observations and drilling campaigns have challenged the typical models for rifted margins by providing evidence for the existence of intermediate cases between the magmatic and amagmatic end‐members. In this contribution, we document the evolution of the Central Campos rifted margin, located in southeast Brazil, based on a combined ...

The Neoproterozoic Throssell Range Group, Western Australia: A Peri‐Marginal Continental Basin in Rodinia and Its Implications for the Centralian Superbasin

Basin Research, Volume 38, Issue 1, January–February 2026.
This study of recent exploration drillcore reveals two sequences separated by a disconformity. Basal alluvial fan to shallow marine lithofacies suggest reactivation of basement faults, and a distinct upwelling signature points to a flooded margin, controlled by differential subsidence of diverse Proterozoic lithosphere.

Seismic Insight on Basement Structure of the Extinct Mid‐Oceanic Ridge in Canada Basin, Arctic Ocean

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 12, December 2025.
Abstract The most accepted theory for the formation of the Canada Basin is that it was created during 66° rotation of Arctic Alaska around the Euler pole located near the Mackenzie Delta sometime during the Mesozoic. Gravity and magnetic anomaly data are consistent with an extinct mid‐oceanic ridge (MOR) in the central basin.

Crustal Heterogeneity Onshore Spitsbergen: Data Integration and Forward Modeling of Potential Field Data

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 12, December 2025.
Abstract The Svalbard archipelago is well‐known for its outcropping geology, but its subsurface geometry and physical properties are less well constrained. To address this knowledge gap, a multidisciplinary approach has been applied to integrate potential field data with seismic reflection profiles, exploration boreholes and geology.

The Cenomanian–Turonian boundary interval in the Western Canada Foreland Basin: Stratigraphy, geochemistry, geochronology and sea‐level changes recorded in expanded and condensed clastic successions

The Depositional Record, Volume 11, Issue 5, Page 1200-1258, November 2025.
Shallow‐marine mudstone of the Cretaceous Kaskapau Formation in the British Columbia foredeep preserves a 185 m thick record of OAE2. The organic carbon‐isotope and osmium‐isotope excursions can be correlated in detail with other Cenomanian–Turonian boundary sections around the world.

The role of shallow banks and marine ice domes in marine‐based ice‐sheet deglaciation

Boreas, Volume 54, Issue 4, Page 649-671, October 2025.
Marine‐based ice sheets are susceptible to collapse and faster retreat than their land‐terminating counterparts. One of the key factors contributing to the relative stability of marine‐terminating ice sheets is the presence of shallow bathymetric banks and islands acting as pinning points for the ice sheet.
