Validating Thermodynamic Models of Arc‐Magma Differentiation and Training Neural Networks for Rapid Thermodynamic Property Inference

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 4, April 2026.
Abstract Magmatic systems are the products of the migration and storage of compositionally evolving magmas within the solid crust. Direct computation of thermodynamic properties during magma transport remains a major challenge in multiphase‐transport modeling due to its computational cost.

Dynamic multifractal characteristics and damage evolution of granite pegmatite with varying biotite content based on acoustic emission monitoring

International Journal of Mining Science and Technology
Biotite content critically influences rock mechanical behavior and threatens underground engineering stability. Uniaxial compression tests with acoustic emission (AE) monitoring were conducted on granite pegmatite samples having varying biotite content ...

Episodic Rifting of a Large Igneous Province Concentrated Along a Microcontinent Boundary

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 4, April 2026.
Abstract Many large igneous provinces (LIPs) comprise once contiguous magmatic products that are now fragmented across multiple tectonic plates. Emplacement of these voluminous magmatic products is commonly coeval with, or shortly followed by, fragmentation into constituent domains.

Surface Deformation of the Nanga Parbat Crustal Diapir in the Northwestern Himalaya Imaged With GNSS and InSAR

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 4, April 2026.
Abstract The Nanga Parbat–Haramosh Massif located in the northwestern syntaxis of the Himalaya is an antiformal structure considered as a crustal diapir undergoing exhumation at a rate larger than 10 mm/yr since 1 Ma. Using GNSS horizontal surface velocities and a vertical and east–west decomposition of the Sentinel‐1 interferometric line‐of‐sight ...

Connecting with tephras: principles, functioning, and applications of tephrochronology in Quaternary science [PDF]

, 2013
Tephrochronology is a unique method for linking and dating geological, palaeoecological, palaeoclimatic, or archaeological sequences or events. The method relies firstly on stratigraphy and the law of superposition, which apply in any study that connects

Variable Oceanic Crust Accretion at a Slow‐Spreading Ridge: A Vp/Vs Ratio Evidence Across the Southwest Sub‐Basin of the South China Sea

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 4, April 2026.
Abstract The opening of the Southwest Sub‐basin (SWSB) of the South China Sea was slow‐spreading and has been propagated toward the southwest. Yet, the structural variability and magmatic accretion process of the SWSB are still enigmatic. Here, utilizing a wide‐angle seismic profile traversing the central segment of the SWSB, we obtain detailed S‐wave ...

Microstructural Controls on Geothermal Reservoir Host Rock Responses to Elevated Pressures and Temperatures

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 4, April 2026.
Abstract Rock microstructure controls geothermal fluid flow within reservoirs hosted in active volcanic environments and as such it is necessary to constrain the microstructural evolution of rocks at elevated pressure and temperature conditions. Despite Andean geothermal systems hosting numerous high enthalpy geothermal plays, there remains a paucity ...

Biotite as a petrogenetic discriminator in the polymetamorphosed rocks: A case study from the Champaner supracrustal rocks, Western India

Geosystems and Geoenvironment
The mineral chemistry of Fe-Mg biotite has served as an aid to the petrogenesis of igneous rocks, especially for identifying the parent magma compositions. Though the interpretation of igneous and metamorphic processes utilizing biotite mineral chemistry

Linking Model Parameter Sensitivities With Hydrological Process Behavior Along Elevation Gradients in Alpine Terrain

Water Resources Research, Volume 62, Issue 4, April 2026.
Abstract Analyzing process interactions in hydrological systems typically requires catchment‐scale hydrological models, where greater model complexity enhances the representation of physical process behavior but also poses challenges related to parameter equifinality.
