Lithospheric Delamination Below the North American Midcontinent Ceased Subsidence in Cratonic Basins

AGU Advances, Volume 7, Issue 1, February 2026.
Abstract Cratonic lithospheres carry a long history of tectonic modifications that result in heterogeneous structures, as revealed by an increasing number of geophysical observations. The existence of cratonic basins indicates protracted periods of tectonic modification, causing subsidence within global continental interiors.

Assessing Magnetic Fluctuations Effects in the South American Sector in Relation to Global Variations Using Ksa Index, Kp Index, and Hybrid Formats During Quiet Times Across the Seasons of the 2020 Solar Minimum

Journal of Geophysical Research: Space Physics, Volume 131, Issue 2, February 2026.
Abstract Geomagnetic indices can be used to quantify variations in geomagnetic activity caused by Sun‐Earth interactions across the magnetosphere and ionosphere. The global Kp index is widely used as a global geomagnetic indicator, but it is based mostly on the Northern Hemisphere with no contributions from South American observatories.

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.

Stress Barriers and Their Impact on Rupture Propagation

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 2, February 2026.
Abstract Earthquake ruptures often exhibit complex behaviors, including abrupt arrest followed by delayed re‐nucleation. While on‐fault stress heterogeneity is a recognized contributing factor, as it can arrest or slow down rupture propagation, its interaction with propagating ruptures remains complex and not fully understood. Here, we study frictional

The Role of Basal Roughness and Assemblage Grain‐Size Distribution in Shaping Granular Rheology and Basal‐Force Signals

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 2, February 2026.
Abstract We present idealized 3‐D discrete element simulations exploring how varying boundary roughness and grain‐size distribution affect bulk granular‐rheology and basal‐force distributions. Boundary roughness has a direct control on the internal static friction coefficient.
