Slab‐Mantle Interaction During Subduction Initiation: Constraints From Trace Element and Sr‐Nd‐Pb Isotope Systematics of Boninite and Other Magmas and Metamorphic Sole in the Oman Ophiolite

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 2, February 2026.
Abstract The Late Cretaceous Oman ophiolite includes a series of volcanic rocks generated during the transition from spreading ridge to protoarc associated with subduction initiation. We analyzed major and trace elements and Sr, Nd, and Pb isotope compositions of lavas and dikes of the protoarc stage, especially boninites. We also analyzed amphibolites

Mantle Transition Zone Topography in New Zealand From Teleseismic P $P$‐Wave Receiver Functions

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 2, February 2026.
Abstract The geology of New Zealand has been shaped by tectonic plate interactions driven by mantle convection over the past 60 million years, but the effects of these interactions on the transition to the lower mantle are not yet well understood. We analyze 10 years of teleseismic P $P$‐wave receiver functions using common conversion point stacking to

Large‐Scale Flow Toward Low‐Velocity Anomalies Reconciles Seismic and Geodynamic Constraints in the Deepest Mantle Beneath Alaska

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 2, February 2026.
Abstract Deep mantle downwellings are typically located away from the two Large Low‐Velocity Provinces (LLVPs) in Earth's mantle. Geodynamic models based on global seismic tomography generally predict that convective flow at the core‐mantle boundary spreads laterally away from downwelling regions and toward LLVPs.

Evolution and Provenance of the Polish Rotliegend in the Southern Permian Basin

open access: yesJournal of Geophysical Research: Earth Surface, Volume 131, Issue 2, February 2026.
Abstract The Southern Permian Basin (SPB) has been extensively explored for ore deposits. However, a comprehensive evaluation of the remaining copper potential, specifically for sediment‐hosted stratiform copper system, remains lacking. This study applies goSPL, an open‐source landscape and stratigraphic evolution model, to reconstruct the Permian rift‐

Improvement of Seasonal Carbon Cycles in HNLC Regions of a Global Ocean Biogeochemical Model Using a Simple Marine Ecosystem Module

open access: yesJournal of Advances in Modeling Earth Systems, Volume 18, Issue 2, February 2026.
Abstract A recent community‐wide evaluation revealed that many state‐of‐the‐art global ocean biogeochemical models displayed seasonal surface CO2 ${\text{CO}}_{2}$ flux variations in the subpolar North Pacific that were out‐of‐phase with observation‐based estimates.
