Magmatic and Tectonic Structures in the Crust Beneath Armenia and Surrounding Regions of Lesser Caucasus Inferred From Body‐Wave Earthquake Tomography

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 1, January 2026.
Abstract The Armenian Highlands, a tectonically active segment of the Arabia‐Eurasia collision zone, exhibit widespread Quaternary volcanism, rapid uplift, and intense seismicity. However, the lithospheric processes driving these phenomena remain poorly understood.

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.

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 ...

Climatology of Medium‐Scale Traveling Ionospheric Disturbances Over Continental US Using GNSS TEC From 2012 to 2023

Journal of Geophysical Research: Space Physics, Volume 131, Issue 1, January 2026.
Abstract Medium‐Scale Traveling Ionospheric Disturbances (MSTIDs) have long been a subject of interest in ionospheric research. However, their spatiotemporal variability across regions, local times, seasons, and solar cycles is very complicated and remains not well established.
