Characterizing Martian Primary Crustal Compositions With Gamma Ray Spectroscopy

Geophysical Research Letters, Volume 53, Issue 2, 28 January 2026.
Abstract Mars's global‐scale chemical maps of the midlatitudes, derived from Mars Odyssey gamma and neutron spectroscopy, have constrained martian geology across a multitude of processes. However, the chemical maps are often used to analyze pre‐defined regions based on mapped geology and/or mineralogy.

Full‐Wave SKS Splitting Intensity Tomography Suggests Depth‐Dependent Upper Mantle Fabrics and Anisotropy Beneath Alaska

Geophysical Research Letters, Volume 53, Issue 2, 28 January 2026.
Abstract Alaska's tectonic complexity makes it ideal for probing upper mantle deformation. We present a 3D shear‐wave anisotropy model obtained by inverting 7,985 SKS splitting intensity measurements from 261 broadband stations using 941 events from 2000 to 2023.

Flocculated Silt, Not Clay, Dominates River Suspended Sediment Load

Geophysical Research Letters, Volume 53, Issue 2, 28 January 2026.
Abstract River mud builds fertile floodplains, combats land loss due to sea level rise, and buries vast amounts of organic carbon. These processes rely on mud settling velocity, which is set by the grain size, mineralogy, and flocculation state of mud. Here we determined these factors using a suspended sediment data compilation from lowland rivers and ...

Mid‐Proterozoic Transient Oxygenation Events Linked to Enhanced Continental Chemical Weathering: Evidence From Carbonate Lithium Isotopes

Geophysical Research Letters, Volume 53, Issue 2, 28 January 2026.
Abstract Potential drivers disrupting mid‐Proterozoic (∼1.8–0.8 Ga) environmental stasis remain poorly constrained. Here we examined carbonate Li isotopes from the ∼1.44 Ga Tieling Formation, North China, to evaluate the effects of continental chemical weathering on coeval oxygenation.

Supershear Transitions and Bilateral Asymmetric Rupture of the 2025 Sagaing (Myanmar) Earthquake Revealed by Geodetic and Seismic Observations

Geophysical Research Letters, Volume 53, Issue 2, 28 January 2026.
Abstract The Sagaing Fault (SF) accommodates major plate motion in Myanmar, yet large earthquakes along it have rarely been captured by modern geodetic and seismic observations. The 2025 Sagaing earthquake generated an exceptionally long rupture (∼535 km), offering a rare opportunity to investigate rupture dynamics along continental transform fault. We
