Role of Post‐Collisional Magmatism in Continental Growth and Reworking Since the Late Archean

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 10, October 2026.
Abstract The mechanisms responsible for the formation and compositional evolution of continental crust remain central questions in Earth science. Post‐collisional magmatism is widely preserved in the continental record; however, its contribution to crustal growth may be underestimated because enriched isotopic signatures obscure juvenile mantle input ...

Europa's Neutral Sodium Exosphere Is Quasi‐Stable Over Decades

Journal of Geophysical Research: Space Physics, Volume 131, Issue 10, October 2026.
Abstract Europa's sodium cloud is thought to be modified by its orbital longitude and by its plasma environment, which modulates with Jovian magnetic geometry. To explore and quantify sodium cloud variability, seven sets of Keck I/HIRES measurements are compared providing comprehensive coverage of orbital and magnetic geometry.

Ground Penetrating Radar Observations of Subsurface Structures From the Makgadikgadi Pans (Botswana): A Terrestrial Analogue of Martian Playa Lakes

Journal of Geophysical Research: Planets, Volume 131, Issue 10, October 2026.
Abstract Playa lakes are considered promising landing sites on Mars because of their strong astrobiological potential. Therefore, sediments and buried structures in terrestrial playa lakes have become the focus of numerous analogue studies. The inclusion of ground penetrating radar (GPR) in the payloads of Martian missions has opened new avenues for ...

Fossilised Pioneer Microbialite Communities on Basaltic Substrates at Lake Ashenge (Tigray, Ethiopia): A Model for Ecosystems in Noachian–Hesperian Martian Lakes?

Journal of Geophysical Research: Planets, Volume 131, Issue 10, October 2026.
Abstract Microbial communities are strongly controlled by local nutrient availability, frequently resulting from mineral weathering and erosion. On Earth, basaltic rocks in habitable alkaline lacustrine environments are often initially colonised by ‘pioneer’ communities that induce the precipitation of fine‐scale microbial carbonate ‘coatings’; on Mars,

3D Architecture of Kodiak Butte as Evidence of Fluvial or Shoal‐Water Environments in Jezero Crater, Mars

Journal of Geophysical Research: Planets, Volume 131, Issue 10, October 2026.
Abstract The Mars 2020 mission has explored depositional environments recorded in a fan‐shaped deposit on the western side of Jezero crater. Kodiak butte is an isolated outcrop of sedimentary rock ∼1 km south of the western fan scarp and may be an erosional remnant of said fan.

Décollement Rheology Controls Crustal Deformation on Early Mars

Journal of Geophysical Research: Planets, Volume 131, Issue 10, October 2026.
Abstract The circum‐Tharsis wrinkle ridge system represents one of the strongest tectonic imprints of early Mars, formed as the planet's largest volcanic province reshaped the lithosphere and redistributed stresses across thousands of kilometers. The coherent spatial pattern of these ridges suggests deformation governed by a laterally continuous basal ...

Subsurface Hydrocarbon Biodegradation in the Context of Microbial Habitability and Hydrogeologic, Thermal, and Geologic Evolution of the Colorado Plateau

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 10, October 2026.
Abstract Subsurface microbial ecosystems associated with hydrocarbon reservoirs are shaped by temperature, salinity, redox gradients, and fluid flow. However, the drivers of microbial activity and hydrocarbon biodegradation over geologic timescales remain poorly constrained.

A Machine‐Learning Surrogate for Differentiable Phase Equilibrium Modeling of Mantle Rocks on a Planetary Scale

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 5, October 2026.
Abstract Modeling processes within Earth's and other planetary bodies' mantle requires constraints from phase equilibrium to infer how changes in phase abundance and composition affect physical properties and geochemical processes. When applying such thermodynamic models on a planetary scale, performance becomes especially crucial.

Limited capacity for rapid acclimation to marine heatwaves in coastal invertebrates

Journal of Animal Ecology, Volume 95, Issue 10, Page 2088-2103, October 2026.
Across 10 coastal invertebrate species, we provide a rare multi‐species test of rapid acclimation to realistic marine heatwaves. Responses are consistently weak, revealing that short‐term plasticity cannot keep pace with warming and may lead to underestimated vulnerability in coastal ecosystems. Abstract Marine heatwaves are increasing in frequency and
