Deep Sources of Recent Volcanism in Armenia Inferred From Ambient Noise Tomography

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 1, January 2026.
Abstract We perform Rayleigh wave ambient noise tomography to investigate crustal seismic velocity structure and sources of volcanism in Armenia. Armenia, a key part of the tectonically and volcanically active Caucasus‐Anatolia region, is actively being deformed by the ongoing Arabian‐Eurasian continental collision.

Olivine‐Ahrensite Phase Relations in the Mg2SiO4‐Fe2SiO4 System as a Function of Temperature

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 1, January 2026.
Abstract Olivine and ahrensite are the primary components of the interiors of Fe‐rich terrestrial planets and meteorites, making their phase relations crucial for planetary science. Moreover, their phase relations can be used for calibrating large‐volume high‐pressure devices such as multi‐anvil apparatus.

Electrical Conductivity of Carbonatite Melts to 20 GPa: Constraints on Partial Melting Atop the 410‐km Discontinuity and in the Lower Mantle Transition Zone

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 1, January 2026.
Abstract Deep‐origin carbonatite melts are considered to be the products of partial‐melting of the oceanic crust in the subduction zones. In this study, we conducted electrical conductivity (EC) measurements on two samples, the composition of which resemble the partial‐melting products atop the 410‐km discontinuity and in the lower part of the ...

Field Observations of Decreasing Rock Fracturing Rates Over Geologic Time

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 1, January 2026.
Abstract Rock fracturing regulates the topography, carbon cycle, geologic hazards, and infrastructure degradation of the Earth. Yet, there remains a paucity of constraints on long‐term fracturing behavior. Here we use field measurements of 2221 clasts across a range of environments and rock types to show that the number and total length of fractures in
