Reconstruction of Rock Uplift in South‐Central Germany Since Late Mesozoic Times

Geophysical Research Letters, Volume 53, Issue 21, 16 November 2026.
Abstract Rock uplift and denudation act as first‐order controls on geological processes that influence atmospheric and ocean composition, and landscape‐forming processes. However, estimating rock uplift rates remains challenging due to the temporal averaging of rates calculated from individual thermo‐ or geochronologic systems.

Melt Production and Volatile Release From Thermochemical Mantle Plumes

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract Mantle plumes are thought to generate Large Igneous Provinces (LIPs), the largest outpourings of lava in the geologic record, which are associated with long‐lasting climatic warming events and mass extinctions. However, the controls on mantle degassing by plumes remain poorly constrained.

Investigating Postseismic Creep in the Laboratory: Testing Dislocation‐Based Models for Transient Creep in the Upper Mantle

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract Studies of postseismic creep often infer a strong reduction in upper‐mantle viscosity after large earthquakes, yet the microphysical mechanism responsible for this behavior remains subject of debate. Here, we present new gas‐medium apparatus experiments at 1100–1200°C on pre‐dried, annealed Åheim dunite (grain size of 400 μ ${\upmu }$m ...

Enriched lithospheric mantle keel below the Scottish margin of the North Atlantic Craton: Evidence from the Palaeoproterozoic Scourie Dyke Swarm and mantle xenoliths

, 2014
The Lewisian Gneiss Complex of NW Scotland represents the eastern margin of the North Atlantic Craton. It comprises mid-late Archaean tonalite-trondhjemite-granodiorite gneisses that were metamorphosed and deformed during the Late-Archaean and ...

Enhanced Melt Supply Promotes Near‐Symmetric Oceanic Crustal Accretion at the Ultraslow Eastern Gakkel Ridge

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract Variations in melt supply can shift slow and ultraslow ridges between magmatic and tectonic accretion modes, but whether this effect persists at Earth's slowest‐spreading ridge remains unclear. The eastern Gakkel Ridge provides a critical test because it spreads at only ∼6–10 mm/yr yet shows anomalously strong magmatism.

Onset of Thrusting at ca. 23 Ma in East Kunlun Mountains, Northern Tibet, Recorded by Syntectonic Strata

Geophysical Research Letters, Volume 53, Issue 19, 16 October 2026.
Abstract The timing of Cenozoic deformation in the East Kunlun Mountains, northern Tibet, is crucial for understanding plateau growth but remains disputed due to the scarcity of direct chronological constraints on specific tectonic structures. Here, we present a high‐density‐sampling magnetostratigraphic record from the Xiaohongshan section, interior ...

Oceanic lithospheric mantle beneath the continental crust of the Chinese Altai

, 2011
Although subduction-accretion is proposed as a major regime in making new continental crust, how the lithospheric mantle forms remains unclear. Formed after the closure of the Palaeo-Asian Ocean, the Ashele basalt shows normal mid-ocean ridge basalt (N ...
