Elevated Asthenospheric Temperature Driving the Partial Melting of Enriched Lithospheric Mantle Feeding the DM‐EM1 Mixing‐Type Magmatism of the Jingpohu Volcano in Eastern NE China: Evidence From Teleseismic P‐Wave Attenuation

Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract The origin of a binary‐mixing of DM and EM1 sources for the Cenozoic intraplate volcanism in eastern Northeast China is yet unclear. Seismic attenuation imaging is a tool that can shed light on this question. Here we present the first map of teleseismic P‐wave attenuation across Northeast China.

MELT INCLUSIONS IN OLIVINE AS A SOURCE OF INFORMATION ON THE COMPOSITION AND EVOLUTION OF DEEP MELTS OF AILLIKITES (ULTRAMAFIC LAMPROPHYRES) OF THE ILBOKICHI UPLIFT, THE SW SIBERIAN PLATFORM

Геодинамика и тектонофизика, 2022
Aillikites are kimberlite-like rocks, important for understanding the composition and processes occurring in the mantle. Melt inclusions represent a reliable source of information.

Multi‐Method Geochronology and P‒T Modeling Unravels the Thermo‐Tectonic History of the Rudall Province, Western Australia

Tectonics, Volume 45, Issue 2, February 2026.
Abstract The Rudall Province (RP) is a Paleo‐Mesoproterozoic belt that records numerous overprinting tectono‐metamorphic events. Situated on the eastern edge of the West Australian Craton (WAC), the RP represents a key area for understanding the Proterozoic assembly and subsequent tectonic history of Western Australia.

Evolution of the Source Mineralogy and Lithospheric Controls on Magmatism During the Northeast Atlantic Continental Breakup

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 2, February 2026.
Abstract The mid‐Norwegian Margin, part of the North Atlantic Igneous Province (NAIP), is a well‐studied volcanic rifted margin formed during the breakup between Greenland and Eurasia ∼56 Ma, with the largest accumulation of magmatic material hosted by the Vøring Margin section.

Effect of gypsum on potassium and iron release from phlogopite under laboratory conditions

Soil & Environment, 2018
This study estimated the effects of gypsum on the potassium and iron release rate from phlogopite under laboratory conditions. A randomized design with the factorial arrangement and three replications was utilized to run the current experiment ...

Reconciling Seismic and Thermo‐Chemical Models of Cratonic Lithosphere

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 2, February 2026.
Abstract Most published global and regional shear‐wave (VS ${V}_{\mathrm{S}}$) velocity models of cratons include a VS ${V}_{\mathrm{S}}$ increase with depth below the Moho, with a maximum at 100–150 km depth. This feature has long been debated, as it appears to require either (implausible) temperature decreases with depth, or substantial, layered ...

Recovery of critical metals from carbonatite-type mineral wastes: Geochemical modeling investigation of (bio)hydrometallurgical leaching of REEs

Green Processing and Synthesis, 2023
Rare earth elements (REEs) are typically found in low concentrations within natural rocks that make up mine tailings, such as carbonates in association with silicates within carbonatite igneous rocks, so it is of interest to develop (bio ...

Chemical‐Thermomechanical Modeling of Open‐System Mass Transfer: Application to the Subduction Interface

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 2, February 2026.
Abstract One of the main limitations in simulating subsolidus metasomatism is the decoupling between thermomechanical models and chemical/thermodynamic modeling. This decoupling amplifies the uncertainty associated with mass transport. Here, we introduce a fluid‐rock chemical‐thermomechanical interaction scheme, which integrates thermodynamic modeling (
