Large‐Scale Submarine Sediment Waves at Macauley Caldera Volcano: In Situ Evidence of High‐Flux, Syn‐Eruptive Submarine Transport

open access: yesGeochemistry, Geophysics, Geosystems, Volume 27, Issue 3, March 2026.
Abstract Two sediment cores were collected from a submarine sediment wave field on the flank of Macauley volcano. Combined with seismic reflection surveys and numerical modeling, we present an integrated model of the formation of large‐scale, eruption‐fed, submarine sediment waves. The sediment waves are large (>100 m high, 1.5 km wide, tens of km long)

Geodynamic Controls on Mantle Differentiation and Preservation of Long‐Term Geochemical Heterogeneity: Focus on the Primitive Undegassed Mantle

open access: yesGeochemistry, Geophysics, Geosystems, Volume 27, Issue 3, March 2026.
Abstract The compositional evolution of the Earth's mantle is the result of mantle differentiation and thermal evolution. Partial melting of mantle materials produces geochemical heterogeneities, allows for degassing and depends on the thermal state of the mantle, itself governed by convection.

Magma Paths of the Karthala and La Grille Volcanoes (Grande Comore) Revisited: New Evidence From Geomorphology and Geochemistry

open access: yesGeochemistry, Geophysics, Geosystems, Volume 27, Issue 3, March 2026.
Abstract Grande Comore, the westernmost island within the Madagascar Comoros Volcanic (MCV) chain, hosts two juxtaposed basaltic volcanoes, Karthala and La Grille, with contrasting lava geochemical signatures and eruption frequencies. Their formation and dynamics have been explained either by a mantle plume or, more recently, as part of a ...

Rapid Slab Rollback Drives Early Cretaceous Back‐Arc Extension in NE China: Implication for Crustal Growth and Episodic Porphyry Mineralization

open access: yesGeochemistry, Geophysics, Geosystems, Volume 27, Issue 3, March 2026.
Abstract The subduction of the Paleo‐Pacific Plate beneath the NE Asian continental margin induced extensive magmatism, providing an excellent opportunity to investigate the interplay between plate dynamics, arc magmatism, continental crust formation, and porphyry mineralization.
