Oxide Gabbros: Transformation From Oceanic Ridge‐Transform Systems to Subduction

open access: yesGeochemistry, Geophysics, Geosystems, Volume 26, Issue 7, July 2025.
Abstract Fluid composition and fluxes in subduction zones are primarily governed by the nature and degree of hydrothermal alteration of the subducting oceanic lithosphere. However, spatial and temporal heterogeneities inherited from mid‐ocean ridge and oceanic transform fault (OTF) systems introduce significant uncertainties in constraining these fluid

Rupture and Relamination of Continental Lithosphere in a Subduction System (Variscan Orogeny, SW Iberia)

open access: yesTectonics, Volume 44, Issue 7, July 2025.
Abstract Relamination is closely connected to subduction zones. Despite the numerous high‐P metamorphic belts recognized on Earth, relamination remains a poorly documented process. We present a continental subduction zone where the exhuming high‐P rocks became a relaminant under the upper plate.

Phase Equilibria Analysis for Metacarbonate With Applications to Zoned Calc‐Silicate Aureoles

open access: yesJournal of Metamorphic Geology, Volume 43, Issue 5, Page 445-465, June 2025.
ABSTRACT Carbonate rocks react with infiltrating hydrothermal fluids to produce zoned calcsilicate assemblages in contact aureoles. Petrogenetic grids provide valuable insights into phase relations, metamorphic temperature (T) and the fluid composition (X) of the metacarbonate systems, as well as semi‐quantification of the prograde decarbonation at ...

Strong scale‐dependent relationships between fine‐root function and soil properties uncovered with spatially coupled sampling

open access: yesNew Phytologist, Volume 246, Issue 6, Page 2506-2521, June 2025.
Summary Substantial fine‐root trait variation is found at fine spatial scales but rarely linked to edaphic variation. We assessed the spatial scales of variation in fine‐root traits and adjacent soils using a spatially coupled, nested sampling scheme along a fertility gradient in a seasonally dry tropical forest tree, Handroanthus ochraceus.

Melt‐Supported Strain Localization at Eclogite‐Facies Conditions Triggered by Syn‐Metamorphic Strength Inversion

open access: yesGeochemistry, Geophysics, Geosystems, Volume 26, Issue 5, May 2025.
Abstract In convergent high‐pressure settings dominated by dry mafic rocks, strain has been proposed to be predominantly localized in eclogite. However, the processes initiating strain localization, accommodating strain and rheological consequences remain to be identified.
