Effects of Aging on Magnetic Mineralogy of Natural Volcanic Glass: Implications for Geomagnetic Paleointensity Recorders

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 1, January 2026.
Abstract Natural volcanic glasses are well represented in the geologic record, and typically contain near‐ideal single‐domain particles required for standard Thellier‐type absolute paleointensity experiments. Young (<∼50–100 ka) glasses have been demonstrated to reliably record Earth's magnetic field.

Brunhes Paleomagnetic Directions and Paleointensities From Northern Hainan Island

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 1, January 2026.
Abstract Paleomagnetic studies typically assume that the long‐term, time‐averaged geomagnetic field behaves as a geocentric axial dipole (GAD). While paleodirectional data over the past five million years generally agree with GAD predictions, mid‐to‐low latitude paleointensity records fail to show GAD, with high values from Hawaii.

The Age and Composition of the Voyager Seamounts: Evidence for a Long‐Lived Marquesas Mantle Source

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 1, January 2026.
Abstract We present new observations on the dynamics and locations of deep mantle reservoirs derived from the ages and compositions of Voyager Seamount Chain lava flows. The previously unexplored Voyager Seamount Chain trends NW–SE between the Mid‐Pacific Mountains and the Northwestern Hawaiian Ridge.

Voluminous Inflated Lobate Flows on the Distal Rift Zones of Axial Seamount, Juan de Fuca Spreading Ridge

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 1, January 2026.
Abstract Three voluminous inflated lobate lava flow complexes on the distal rifts of Axial Seamount are much larger than other known flows in the global spreading system. Each complex is 65–100 km2, is up to 130 m thick, and is ∼3.0–4.6 km3, almost 100 times the volumes of historical Axial flows.

From the Bottom Up: Calculating Mantle‐Derived Magma Flux Using Subduction Parameters and Petrologic Constraints at Oceanic Arcs

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 1, January 2026.
Abstract Mantle‐derived magma flux has a first‐order control on long‐term volcanic productivity, volatile cycling, and crustal growth in convergent margins. However, the factors controlling it remain unclear. We used a simplified, 3D conceptualization of an intraoceanic subduction zone and petrologic constraints on mantle melting to calculate mantle ...
