Active Tectonics of the Eastern and Southern Alps ‐ Crustal Response to Deep Processes? A Review

open access: yesTectonics, Volume 45, Issue 8, August 2026.
Abstract Owing to the low N‐S convergence rates between Adria and Europe, crustal deformation rates in the Alps and its forelands are low. Active tectonics are, therefore, difficult to study, especially as non‐tectonic landscape forming processes can erase or modify the tectonic surface imprint. Large‐scale and dense seismological data recently offered

Inversion by Intrusion: Magma‐Driven Shortening in the Turkana Rift (East Africa)

open access: yesTectonics, Volume 45, Issue 8, August 2026.
Abstract Late Pliocene to Pleistocene inversion in the Turkana Rift, observed on seismic reflection data and in outcrop, presents a tectonic paradox by indicating local shortening in an overall extensional setting. Previous studies attributed this inversion either to the reactivation of obliquely oriented structural weaknesses or to reorientation of ...

Architecture of the Patrimonio Fault System and the Miocene Post‐Orogenic Extension in Alpine Corsica (France)

open access: yesTectonics, Volume 45, Issue 8, August 2026.
Abstract The exhumation of Alpine Corsica is the result of Oligocene‐Miocene lithospheric back‐arc extension in the wake of the eastward migration of Apenninic subduction. Although the geometry, kinematics and timing of ductile detachments are well constrained, the brittle extension leading to final exhumation of Alpine Corsica is less documented.

Massive Rocky Planets May Suppress Deep Melting

open access: yesAGU Advances, Volume 7, Issue 4, August 2026.
Abstract Melting properties of silicates are critical to understanding the thermal evolution of rocky planetary interiors. In the deep mantles of massive rocky planets, post‐post‐spinel Mg2SiO4 ${\text{Mg}}_{2}{\text{SiO}}_{4}$ is potentially one of the most abundant mineral phases, yet its melting behavior remains unconstrained. Here, we determine the

Spatial Dependence of High‐Frequency Ground Motion Along the Chilean Subduction Zone From Aftershock Sequences of the Mw 8.8 Maule and Mw 8.2 Iquique Earthquakes

open access: yesEarth and Space Science, Volume 13, Issue 8, August 2026.
Abstract The Chilean subduction zone is a highly active seismic region, producing megathrust earthquakes approximately every decade. We apply a stochastic approach to assess spatial variations in seismic wave characteristics along the Chilean trench using weak motion data.

A Physics‐Based Frequency‐Temperature Seismic Anelastic Attenuation Model for Planetary Ice Shells

open access: yesEarth and Space Science, Volume 13, Issue 8, August 2026.
Abstract Intrinsic attenuation in planetary ices remains poorly constrained at seismic frequencies and low temperatures, limiting quantitative predictions of wave propagation in icy moons. Existing models typically rely on constant‐Q, or power‐law formulations that lack microphysical grounding and fail to capture the strong temperature sensitivity of ...

Kamafugite Magma Pathways and Lava‐Flow Paleotopography From Three‐Dimensional Audiomagnetotelluric Imaging Constrained by Borehole Data

open access: yesEarth and Space Science, Volume 13, Issue 8, August 2026.
Abstract An audiomagnetotelluric (AMT) survey was conducted within the Alto Paranaíba Igneous Province, southeastern Brazil, to delineate shallow occurrences of kamafugite, a rare ultrapotassic volcanic rock worldwide. A dense grid of AMT stations was deployed, allowing the construction of a high‐resolution 3D electrical resistivity model ...

Early–Late Carboniferous Tectonic Evolution of the Northern North China Craton (NE China): Constraints From Zircon Ages, Geochemistry, and Crustal Thickness Modeling

open access: yesGeochemistry, Geophysics, Geosystems, Volume 27, Issue 8, August 2026.
Abstract The tectonic evolution of the northern margin of the North China Craton (NCC) remains controversial. In this study, we obtained zircon U–Pb ages, geochemical data, and Sr–Nd isotopic data for volcanic rocks, and detrital zircon ages for sedimentary rocks from the Yufutun, Tongqigou, and Benxi formations in central‐southern Jilin Province, NE ...

Evolution of Tectonically Accreted Topmost Oceanic Lithospheric Mantle Based on Seismic Tomography Constraints at the Ultraslow‐Spreading Southwest Indian Ridge

open access: yesGeochemistry, Geophysics, Geosystems, Volume 27, Issue 8, August 2026.
Abstract Oceanic lithosphere formed at the global mid‐ocean ridge system makes up >60% of Earth's solid surface. Its uppermost ∼6 km are accreted either magmatically, where mafic melt is available, or tectonically, where this melt is absent. The magmatically accreted lithosphere is known to evolve with age, as demonstrated by its velocity increase ...

Crustal Thickness Inversion From Magmatic Geochemistry Reveals Spatiotemporal Evolution and Two‐Stage Uplift of the Iranian Plateau

open access: yesGeochemistry, Geophysics, Geosystems, Volume 27, Issue 8, August 2026.
Abstract The Cenozoic topographic growth of the Iranian Plateau, situated at the Arabia‐Eurasia collision front, provides insights into continental collision dynamics. However, the relative contributions of tectonic shortening versus deep mantle processes to crustal thickening remain debated because systematic quantitative constraints on paleo‐crustal ...
