Multi‐Stage Evolution of Subducted Oceanic Mantle: The Marlborough Ultramafic Suite (New England Orogen, Australia)

open access: yesGeochemistry, Geophysics, Geosystems, Volume 27, Issue 9, September 2026.
Abstract Oceanic lithosphere is continuously destroyed by subduction, challenging our ability to develop tectonic reconstructions. One way to tackle this problem is to examine relics of once‐consumed oceanic domains preserved along convergent margins. In the New England Orogen (eastern Australia), disrupted exposures of ultramafic rocks loosely define ...

Past the First Date: Ensemble Concordant–Discordant Comparison for Zircon Pb‐Loss Analysis

open access: yesGeochemistry, Geophysics, Geosystems, Volume 27, Issue 9, September 2026.
Abstract Zircon uranium–lead (U–Pb) geochronology is a cornerstone of Earth science for resolving the timing of deep‐time processes, yet the U–Pb system does not always behave as a closed chronometer. Selective loss of radiogenic Pb during fluid alteration or thermal disturbance can shift isotopic ages and generate discordant analyses. Some zircon data

Depositional History of the Namibian Mud Belt Reveals Late Holocene Weakening of the Benguela Coastal Current

open access: yesGeochemistry, Geophysics, Geosystems, Volume 27, Issue 9, September 2026.
Abstract We investigate late Holocene changes in the northern Benguela Upwelling System using a multi‐proxy approach on shallow shelf deposits from the Namibian mud belt. Three sediment cores characterized by organic carbon‐rich, anoxic, and partly gas‐bearing sediments were retrieved along a sampling transect at 23°S in August 2019.

Investigating Layered Cratonic Lithosphere in the Fennoscandian Shield

open access: yesGeochemistry, Geophysics, Geosystems, Volume 27, Issue 9, September 2026.
Abstract Cold, thick, and chemically depleted lithosphere with high seismic velocity and low attenuation characterizes continental cratons. However, discrepancies between xenolith‐based thermal constraints and those inferred from surface‐wave seismic models, together with the widespread observation of mid‐lithosphere discontinuities, challenge the ...

Comment on “Parameterizations of Clinopyroxene—Melt Trace Element Partition Coefficients” by Bédard, J. H. (2014)

open access: yesGeochemistry, Geophysics, Geosystems, Volume 27, Issue 9, September 2026.
Abstract A better understanding of how trace element partition coefficients vary with melt and mineral composition, temperature, pressure, oxygen fugacity and fluid composition is essential to geochemical modeling of magmatic rocks. The Nernst partition coefficient D is the ratio of the concentration (by weight) of a trace element in a solid phase ...

Impacts of Neutral Wind‐Driven Currents on Geomagnetic Disturbances and Magnetospheric Dynamics During the May 2024 Storm

open access: yesJournal of Geophysical Research: Space Physics, Volume 131, Issue 9, September 2026.
Abstract The neutral wind dynamo generates ionospheric currents that can significantly affect high‐latitude electrodynamics during geomagnetic storms, yet its role in global magnetosphere‐ionosphere coupling is often underrepresented. We quantify the impact of wind‐driven currents on geomagnetic disturbances (GMDs) and magnetospheric dynamics during ...
