The Piedmont Zone From the Western Alps (Italy): New Insights From High‐Pressure Ophiolitic Metasediments in the Soana Valley

Journal of Metamorphic Geology, Volume 43, Issue 9, Page 909-937, December 2025.
ABSTRACT Metaophiolites and metasediments of the Piedmont Zone are exposed in the Soana Valley, a poorly studied area of the Western Alps, located between the Europe‐related Gran Paradiso massif and the Adria‐related Sesia–Lanzo zone. Previous investigations reported the occurrence of only greenschist‐facies metamorphic assemblages in the metasediments.

Helicosphaera carteri (Prymnesiophyceae) under high carbon dioxide: An experimental study

Journal of Phycology, Volume 61, Issue 6, Page 1576-1590, December 2025.
Abstract The coccolithophore Helicosphaera carteri is an understudied, yet ecologically and biogeochemically important, marine calcifier. Hence, its response to ocean acidification has implications for ecosystem function and the marine carbon cycle. Here we employed dilute batch cultures featuring a coupled C‐system manipulation (295, 444, and 600 μatm

Sedimentary record of submarine gravity‐flow events in the southern Ryukyu forearc during the last 200 000 years: Archive of mega‐earthquakes and tsunamis

Sedimentology, Volume 72, Issue 7, Page 2323-2360, December 2025.
ABSTRACT Despite high convergence velocity, the southern Ryukyu subduction has relatively low and sparse instrumental seismicity, in contrast with the Yaeyama Islands, hit by huge tsunamis over the last few thousand years. This study explores the potential of deep marine sediments to record past large earthquakes and tsunamis.

Sedimentological characterisation is a necessary prerequisite for interpretation of stable carbon isotope ratios of bulk sediment from reefal settings

Sedimentology, Volume 72, Issue 7, Page 2361-2392, December 2025.
ABSTRACT For most of Earth history, carbonate sediments deposited in shallow marine settings are the only remaining archive of changing biogeochemical cycles. All deep‐sea sediments older than >200 Ma have been subducted and are therefore lost from the record. Stable carbon isotope (δ13C) values of shallow marine carbonates are available for older time

Unraveling the Controls of Rock Permeability Change During Volatile‐Consuming Reactions

Geophysical Research Letters, Volume 52, Issue 22, 28 November 2025.
Abstract Permeability changes of rocks are critical in hydration and carbonation, as they significantly affect the subsurface chemical composition. This study uses a one‐dimensional reactive‐transport‐deformation model to define the dimensionless factors controlling permeability in the presence of rock fracturing, mineralization, and fluid flow ...

Similar Liquid Composition and Surface State of Titan's Northern Lakes From Cassini Bistatic Radar Experiment

Geophysical Research Letters, Volume 52, Issue 22, 28 November 2025.
Abstract During the T119 bistatic radar (BSR) experiment, the Cassini spacecraft observed a collection of lakes in Titan's Northern Lake District. Specular reflections from liquid surfaces were clearly detected at X‐band ground‐based station DSS‐43 (Canberra), spaced out by sudden drops of power in correspondence to solid terrains.
