Terrestrial Analogs to Titan for Geophysical Research

open access: yesReviews of Geophysics, Volume 64, Issue 2, June 2026.
Abstract Saturn's moon Titan exhibits remarkable parallels to the Earth in many geophysical and geological processes not found elsewhere in the solar system at the present day. These include a nitrogen atmosphere with a condensible gas—methane—replacing the Earth's water, leading to an active meteorology with rainfall and surface manifestations ...

Arc Heat Flow and Magmatic Heat Budgets

open access: yesReviews of Geophysics, Volume 64, Issue 2, June 2026.
Abstract We evaluate hydrothermal heat loss from 11 volcanic‐arc segments (∼6,000 km of arc length, ∼10% of the global total), motivated by the observation that much magmatic heat ultimately crosses the land surface as heated aqueous fluid. Heat loss takes place by volcanic eruption, geothermal heat conduction to the surface, fumarolic (vapor ...

Multi‐Proxy Thermal History of Basin Heating During Cordilleran Orogenesis in the Magallanes‐Austral Retroarc Foreland Basin, Patagonian Andes

open access: yesBasin Research, Volume 38, Issue 3, May–June 2026.
Paleogene unconformity development from ~64 to 22 Ma for the Magallanes‐Austral retroarc foreland basin (MAB). Schematic shows (A) MAB foreland subsidence and basin infilling, (B) onset of cooling and basin inversion as subducting plate shallows, (C) continued foreland uplift, erosion and cooling as the oblique Farallon‐Phoenix ridge subducts beneath ...

Tracking Deep Magma Migration Through Diffuse CO2 Degassing: Insights From Piton de la Fournaise Volcano (2013–2023)

open access: yesGeochemistry, Geophysics, Geosystems, Volume 27, Issue 4, April 2026.
Abstract Volcano monitoring requires identifying and distinguishing physico‐chemical processes at various depths within magma plumbing systems and their links to volcanic activity. Long‐term monitoring of deep magma reservoirs, extending down to tens of kilometers, is crucial even though signals from these depths are often altered or attenuated before ...

Eocene Tectonic Change in the South Pacific Caused Exhumation of the Transantarctic Mountains in Northern Victoria Land, Antarctica

open access: yesNew Zealand Journal of Geology and Geophysics, Volume 69, Issue 1, March 2026.
Apatite fission‐track and (U‐Th)/He data indicate rapid exhumation of northern Victoria Land at 40–30 Ma, correlating with opening of Adare Trough at 43–28 Ma. Exhumation was greatest close to the Ross Sea, consistent with other regions of the Transantarctic Mountains.

Magma Paths of the Karthala and La Grille Volcanoes (Grande Comore) Revisited: New Evidence From Geomorphology and Geochemistry

open access: yesGeochemistry, Geophysics, Geosystems, Volume 27, Issue 3, March 2026.
Abstract Grande Comore, the westernmost island within the Madagascar Comoros Volcanic (MCV) chain, hosts two juxtaposed basaltic volcanoes, Karthala and La Grille, with contrasting lava geochemical signatures and eruption frequencies. Their formation and dynamics have been explained either by a mantle plume or, more recently, as part of a ...

Dynamic Models of Magma Storage Within a Damaging, Strain‐Softening Crust and Their Application to Sierra‐Negra's Pre‐Eruptive Inflation Pattern

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 3, March 2026.
Abstract Prior to its 2005 and 2018 eruptions Sierra Negra's caldera displayed decades‐long inflation characterized by successive transient uplifts culminating in accelerating uplifts in the 1–2 years prior to each eruption. These observations motivated the question: can these transient uplifts be explained by internal dynamics of the magma system ...

A Fluvio‐Lacustrine Environment Preserved in the Jezero Crater Inlet Channel, Neretva Vallis, Mars

open access: yesJournal of Geophysical Research: Planets, Volume 131, Issue 1, January 2026.
Abstract Martian fluvial valleys provide evidence for the surface flow of liquid water, making them a key target for rover‐based investigations of ancient habitability. The Mars 2020 Perseverance rover spent ∼85 sols exploring the Bright Angel formation, exposed across the floor of Neretva Vallis: the western inlet channel of Jezero crater.
