Journal of Geophysical Research: Earth Surface, Volume 131, Issue 4, April 2026.Abstract Landslides represent one of the most devastating natural hazards in mountainous regions, posing significant threats to human safety, infrastructure and ecosystems. It is well established that there is a connection between meteorological factors and landslide occurrences but the mechanisms of these interactions and the impacts of climatic ...

The Papoose Flat Pluton of eastern California: a reassessment of its emplacement history in the light of new microstructural and crystallographic fabric observations [PDF]
, 2017 One of the most outstanding apparent examples in N America of a forcibly emplaced pluton is the Papoose Flat Pluton of eastern California. Sideways expansion of this granitic pluton, during emplacement into a series of Cambrian shelf strata, has been ...

Geochemical Disequilibrium at the Brittle‐Ductile Transition
Geochemistry, Geophysics, Geosystems, Volume 27, Issue 4, April 2026.Abstract We investigate the microtextural, microchemical, and isotopic effects of late‐stage ductile deformation in quartzite mylonites and kyanite–muscovite–quartz veins from the Raft River shear zone (Utah). Quartz microstructures record pervasive disequilibrium, expressed by unannealed features including undulatory extinction, deformation lamellae ...

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.

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.

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 4, April 2026.Abstract When, where, and how much fluid is released from subducting oceanic crust control deformation, element cycling, and magmatism in subduction zones. However, the palimpsest of tectonometamorphic processes in the exhumed rock record complicates the relation of geologic observations to geodynamic models of subduction fluid sources and transport ...

, 1980 Plutonic rocks of the Canadian Shield are being assessed as a potential host medium for the storage of radioactive waste. A study of the geological framework of three structural provinces (Superior, Southern, and Grenville) within Ontario has resulted in an inventory of 1365 plutons which are identified on Map 1533A at a scale of 1:1 000 000.

Structure of the North‐Central Chile Subduction Zone From Local Earthquake Tomography
Journal of Geophysical Research: Solid Earth, Volume 131, Issue 4, April 2026.Abstract The fluid cycle in subduction zones prescribes large parts of its structure and seismogenic behavior. Background seismicity inside the downgoing slab is linked to fluid release from dehydration reactions, whereas fluid overpressure along the plate interface can alter interplate coupling, megathrust earthquakes, and the presence or absence of ...

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 ...

Journal of Geophysical Research: Planets, Volume 131, Issue 4, April 2026.Abstract Detrital sediments that accumulate downstream and are preserved in sedimentary rocks can allow characterization of geologic formations that are inaccessible for spatial or temporal reasons. However, mixing, sorting, and alteration of sediment during transport may complicate reconstruction of protolith characteristics.
