Intraplate Basalts in Eastern Continental China Record the Subduction History of the Pacific Plate
Geophysical Research Letters, Volume 52, Issue 16, 28 August 2025.Abstract To assess whether intraplate magmatism in eastern continental China records the subduction history of the Pacific plate, we plotted elemental compositions of the volcanic rocks in this region since the Early Cretaceous as a function of age. These rocks show distinct compositional transitions at ∼110 and ∼50 Ma, coinciding with the cessation of

Geophysical Research Letters, Volume 52, Issue 16, 28 August 2025.Abstract During the final stages of seafloor spreading in the East Sub‐basin of the South China Sea, spreading transitioned from slow to ultraslow before cessation. However, post‐spreading volcanism has obscured the original fabric along or near the extinct spreading ridge (ESR).

Variations in Hawaiian Plume Flux Controlled by Ancient Mantle Depletion
AGU AdvancesMantle plumes—upwellings of buoyant rock in Earth's mantle—feed hotspot volcanoes such as Hawai‘i. The size of volcanoes along the Hawai‘i–Emperor chain, and thus the magma flux of the Hawaiian plume, has varied over the past 85 million years.

A comprehensive petrological and geochemical dataset is reported in order to define the thermo-compositional characteristics of Ti (Fe)-enriched picrite-basalt lavas (HT2, TiO2 3-7 wt%), erupted close to the axial zone of the inferred Afar mantle plume ...
