Pleistocene Smoothing and Resurfacing of Appalachian Ridgelines by Periglaciation

Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.
Abstract Pleistocene cold periods created widespread periglacial conditions across mid‐latitudes, but isolating their geomorphic impact from modern climate, tectonics, and rock strength is challenging. We studied Appalachian (Eastern U.S.) ridgelines across a paleoclimate gradient, controlling for bedrock and structure, to test if colder periglacial ...

New Insights Into the Cooling of the Oceanic Lithosphere From Surface‐Wave Tomographic Inferences

Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.
Abstract How oceanic plates cool and thicken with age remains a subject to debate, with several thermal models supported by apparently contradictory data. Combining a novel imaging technique that balances resolution and uncertainty with finite‐frequency surface‐wave measurements, we build tomographic model SS3DPacific to revisit the cooling style of ...

P‐ and S‐wave Velocity Measurement of Lunar Orthopyroxene up to 5.5 GPa and 1,273 K: Implication for the Iron Content of the Lunar Upper Mantle

Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract Seismological observations in the lunar mantle, in conjunction with experimental knowledge on the elastic wave velocities and density of lunar mantle minerals, provide important constraints on the composition and mineralogy of the lunar mantle. Here we report elastic wave velocities and density of a lunar orthopyroxene (Mg0.84Fe0.13Ca0.03SiO3)

Late Triassic Hydroclimatic Changes in Central China Linked to Evolving Mountain Topography

Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract During the Late Triassic, tropical Pangea drifted northward into subtropical latitudes and became progressively drier. In contrast, South China, despite experiencing a similar latitudinal shift, transitioned from an arid to humid climate. Based on the sedimentary record of the Zigui Basin, this study constrains the arid to humid climatic shift

Elevated Asthenospheric Temperature Driving the Partial Melting of Enriched Lithospheric Mantle Feeding the DM‐EM1 Mixing‐Type Magmatism of the Jingpohu Volcano in Eastern NE China: Evidence From Teleseismic P‐Wave Attenuation

Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract The origin of a binary‐mixing of DM and EM1 sources for the Cenozoic intraplate volcanism in eastern Northeast China is yet unclear. Seismic attenuation imaging is a tool that can shed light on this question. Here we present the first map of teleseismic P‐wave attenuation across Northeast China.

Sound Velocities of FeO‐Bearing Ringwoodite and Majorite: Implication for Martian Mantle Seismic Profiles

Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract Compressional and shear wave velocities (Vp, Vs) of candidate Martian deep‐mantle minerals, FeO‐rich ringwoodite ((Mg0.66Fe0.34)2SiO4) and majorite (Mg0.75Fe0.10Al0.26Ca0.07Si0.84O3), were measured up to 25 GPa and 700 K using Brillouin light scattering coupled with externally‐heated diamond anvil cells.

Migration of Multimodal Deep Crustal Earthquake Swarm Beneath the Abu Volcano Group, Japan

Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract Earthquakes in the lower crust, where high pressures and temperatures favor ductile deformation, are rare but occasionally occur beneath active volcanic centers, providing insights into deep magmatic processes. We analyze a deep crustal earthquake swarm (February–August 2025) of over 5,000 events beneath the Abu Volcano Group, Japan.
