Geochemical Constraints on Spatial‐Temporal Distribution and Origin of Anomalous Mantle in the Western Pacific Basins

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 6, June 2026.
Abstract Seafloor basalt samples recovered from the Caroline Basin (CB), the Parece Vela Basin (PVB), and the Western Philippine Sea Plate (WPSP) are analyzed for whole‐rock major and trace elements (including H2O), Sr‐Nd‐Pb‐Hf isotopes and 40Ar‐39Ar age‐dating.

New Insights Into Hikurangi Subduction Inputs and Megathrust Host Rocks Spanning Along‐Margin Changes in Fault Slip Behavior

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 6, June 2026.
Abstract The seismic behavior of subduction megathrusts varies spatially and is influenced by the properties of subducting plates, including their sedimentary cover. Characterizing these subduction inputs is essential for understanding the mechanisms behind fault slip variability.

Low Heat Flow Near the Deformation Front of the Northern Hikurangi Margin Revealed by Deep Borehole Observatories

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 6, June 2026.
Abstract Deep borehole observatories installed during IODP Expedition 375 at Sites U1518 and U1519 along the northern Hikurangi subduction margin offshore New Zealand provide new constraints on the thermal structure of the frontal prism, where frequent shallow slow slip events occur.

Geochemical and Isotopic Constraints on Long‐Lived Source Enrichment and Mantle Evolution in Paleoproterozoic Cratonic Lamprophyres

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 6, June 2026.
Abstract The cratonic lithospheric mantle records complex metasomatic processes and is frequently tapped by alkaline magmatism, offering a unique opportunity to trace the progressive evolution of the mantle. In the present contribution, we investigate a newly identified calc‐alkaline lamprophyre field from the Neoarchean Jonnagiri Schist Belt, Eastern ...

Multidisciplinary Investigation of Healy Submarine Volcano (Kermadec Arc, New Zealand) Using AUV and Submersible Data: Structural Control on Magmatic and Hydrothermal Processes

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 6, June 2026.
Abstract We present a comprehensive multidisciplinary investigation of the Healy submarine volcano in the southern Kermadec arc, northeast of New Zealand. We show the first results of sidescan‐sonar data collected at a submarine arc volcano by an Autonomous Underwater Vehicle (AUV).
