Late‐Stage Rift Evolution at Back Arc Basins: Insights From a Tomography Experiment at Orca Volcano, Bransfield Basin

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 2, February 2026.
Abstract Back‐arc basins provide insights into the processes governing the evolution of continental rifting to seafloor spreading. The Bransfield basin hosts a back arc rift that is hypothesized to be in the late stages of this transition. Orca volcano is a submarine volcano that lies on the most evolved portion of the rift.

Evolution of the Source Mineralogy and Lithospheric Controls on Magmatism During the Northeast Atlantic Continental Breakup

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 2, February 2026.
Abstract The mid‐Norwegian Margin, part of the North Atlantic Igneous Province (NAIP), is a well‐studied volcanic rifted margin formed during the breakup between Greenland and Eurasia ∼56 Ma, with the largest accumulation of magmatic material hosted by the Vøring Margin section.

Low Water Content of the Lower Continental Crust Induced by Decompression Melting: Evidence From the Weichang Granulite Xenoliths in the Northern North China Craton

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 2, February 2026.
Abstract The water content of granulite xenoliths from the Cenozoic Weichang basalts in the northern North China Craton (NCC) is investigated to constrain the nature and evolution of the lower crust. Granulites are categorized into felsic and mafic groups, characterized by widely developed glass‐bearing sieve textures in their constituent minerals ...

Subduction System Response to Ribbon Collision: Implications on the Intra‐Plate Force Balance and the Style of Slab Deformation

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 2, February 2026.
Abstract Ribbon collision is a process that can rapidly disturb the symmetry of subduction zones. Previous studies have demonstrated how ribbon collision causes rotation at the surface and contortion in the slab, but have only focused on the surface kinematics.

Crustal Structure of Laurentia and Peri‐Gondwanan Terranes Beneath Ireland and Britain and Comparison With Eastern North America

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 2, February 2026.
Abstract The Appalachian‐Caledonian orogen was built during the Paleozoic by accretion of peri‐Gondwanan terranes onto Laurentia, culminating in the formation of Pangea. During the Mesozoic, Pangea broke apart, displacing one section of the belt to eastern North America and another to northwestern Europe.
