Systematics of Marmosa Subgenus Micoureus With Emphasis in ‘rapposa’ Group (Didelphidae, Marmosini): Geographic Variation and Revalidation of M. budini

Zoologica Scripta, Volume 55, Issue 5, Page 681-692, September 2026.
ABSTRACT Micoureus is the most species‐rich subgenus within the genus Marmosa. Conflicting arrangements regarding the number of species comprising this subgenus have been proposed and the validity of M. budini has been debated. Here, we used an approach integrating genetic and morphological data were conducted to reanalyze the ‘rapposa’ group ...

An Inflating Upper Mantle Magma Reservoir Beneath the Tip of the Condor Seamount, Azores Revealed by Rapid‐Response Ocean‐Bottom‐Seismometer Data

Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract Condor Seamount is among the most seismically active regions on the Azores Plateau. In December 2019, an earthquake crisis occurred at the tip of the seamount, which was strongly felt on nearby islands. Two months after the peak of the crisis, we deployed a local network of five ocean‐bottom seismometers around the seamount, recording ...

Origin of Long‐Wavelength Variations in Crustal Thickness on Rocky Planets

Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract Long‐wavelength crustal thickness variations are observed on telluric planets, particularly on Mars and the Moon whereas Mercury appears to lack such variations. They may stem from two early‐stage positive feedback mechanisms that can emerge in stagnant‐lid planets.

Corundum Discovered by SuperCam and the Perseverance Rover at Jezero Crater, Mars

Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract Mars is primarily composed of mafic mineral assemblages and their alteration products, but small, scattered rocks strewn across the landscape offer clues to greater petrological diversity. While traversing the Jezero crater rim, the Perseverance rover encountered several plagioclase‐rich light‐toned float rocks.

Abrupt Suppression of Tectonic Tremors Outside the Stress Shadow of Mendocino Earthquakes

Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract Tectonic tremor is a long‐duration noise‐like seismic signal associated with slow fault motion at major plate boundaries. Due to their remarkable sensitivity to stress perturbations, tremors serve as invaluable probes of the mechanical state and stress conditions deep within fault zones.

Global Evidence for Off‐Axis Flexural Modification of Abyssal Hill Faults at Mid‐Ocean Ridges

Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract Young oceanic lithosphere flexes as axial topography decays across mid‐ocean ridge shoulders, yet this deformation has been quantified at only a few segments, leaving its global expression poorly constrained. We analyzed 50 across‐axis bathymetric profiles from 21 regions spanning slow to fast spreading rates, identified 1,201 abyssal‐hill ...

Hydrogen‐Enhanced Grain Boundary Conductivity Explains High‐Conductivity Anomalies in Trans‐Lithospheric Shear Zones

Geophysical Research Letters, Volume 53, Issue 15, 16 August 2026.
Abstract Magnetotelluric (MT) surveys reveal high electrical conductivity anomalies along major trans‐lithospheric shear zones. Given that trans‐lithospheric shear zones are proposed conduits for deep‐Earth volatiles, we employ molecular dynamics simulations to quantify H+ diffusivity and electrical conductivity at olivine grain boundaries.

Gravitational Stability of Hydrated SiO2 and Basaltic Crust in the Lower Mantle

Geophysical Research Letters, Volume 53, Issue 15, 16 August 2026.
Abstract We determined thermal equations of state of hydrated stishovite and CaCl2‐type SiO2 up to 100 GPa and 3,000 K to assess the gravitational stability of hydrated stishovite and basaltic crust in the lower mantle. Using machine‐learning based atomistic simulations, we examined three hydrogen dissolution mechanisms: hydrogarnet‐type, interstitial ...

Potential Bias in Inferred Megathrust Slip Rates Induced by the Neglect of Material Heterogeneity

Geophysical Research Letters, Volume 53, Issue 15, 16 August 2026.
Abstract Accurate knowledge of the pattern of interseismic coupling on megathrusts is critical to preparing for future earthquakes and tsunamis. However, published models for a given fault zone commonly differ widely, making hazard assessment difficult.
