Geochemical Characteristics of Metasediment—Rich Lower Continental Crust: Insights From the Ivrea‐Verbano Zone (DIVE Drilling Project, ICDP Expedition 5071, Val d’Ossola, Italy)

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 11, November 2026.
Abstract Whole‐rock geochemical data from two drill cores obtained through the ICDP (International Continental Scientific Drilling Program) funded Drilling the Ivrea‐Verbano Zone (IVZ) (DIVE) project: 5071_1_B (Ornavasso) and 5071_1_A (Megolo), provide new insights into the composition of the lower continental crust (LCC) in the IVZ. Borehole 5071_1_B (

A Late Cretaceous Aborted Spreading Center in the Northern Arabian Sea Recorded by the Laxmi Basin

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 11, November 2026.
Abstract The Laxmi Basin (LB), a marginal depression, is a prominent geomorphic feature in the northern Arabian Sea. Understanding how the basin formed has important implications for the India–Seychelles breakup and the evolution of the western Indian Ocean.

An Experimental Study of Particle‐Laden Jet Noise as an Analogue to Tephra‐Laden Volcanic Eruptions

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 11, November 2026.
Abstract Explosive volcanic eruptions produce vast amounts of acoustic energy, generally in the infrasound range. For sustained eruptions, infrasound is often dominated by jet noise, a form of noise similar to the sound from human‐made jet engines. Jet noise largely results from the combination of two sound‐producing components: fine‐scale turbulence ...

Hydrothermal Sealing at Turrialba, Poás, and Rincón de la Vieja Volcanoes (Costa Rica) Promotes Phreatic and Phreatomagmatic Eruptions

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 11, November 2026.
Abstract Hydrothermal sealing is a mechanism thought to be responsible for challenging‐to‐forecast phreatic and phreatomagmatic eruptions. To better understand this process, we present a study in which we assessed the textural, mineralogical, and physical properties (porosity, permeability, and tensile strength) of blocks of hydrothermal seal that were

Sulfidation Reaction Mechanisms of Olivine and Diopside at Mercury's Reducing Conditions

Journal of Geophysical Research: Planets, Volume 131, Issue 11, November 2026.
Abstract The surface of Mercury contains elevated amounts of sulfur of up to 4 wt.%. Volcanic degassing of S from the interior of the planet could have initiated sulfidation reactions between the degassed S and surface materials in the planet's past, leading to the observed surface S enrichment.
