Davemaoite Elasticity Reveals Slab‐Induced Heterogeneity in the Mantle Transition Zone

Geophysical Research Letters, Volume 53, Issue 2, 28 January 2026.
Abstract The observed 2%–7% low‐shear velocity (VS) anomalies near the subducted slab at the bottom mantle transition zone (MTZ) indicate strong lateral heterogeneity, which is commonly attributed to subducted oceanic crust. However, davemaoite, a major constituent of the subducted oceanic crust, has been poorly constrained in its elasticity, hindering

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.

Crustal Flow‐Driven Plateau Growth and Expansion Front in NE Tibet: Insights From High‐Resolution Attenuation Tomography With High‐Density ChinArray Lg Data

Geophysical Research Letters, Volume 53, Issue 2, 28 January 2026.
Abstract The Northeastern (NE) Tibet, as the front of plateau growth, widely absorbs northeastward extrusion, leading to significant uplift and forming a basin‐mountain tectonic framework. However, it remains unclear how the crust of NE Tibet deformed in response to the far‐field effects of the India‐Eurasia collision.
