The Seismic Signature of the Atlantis Massif Oceanic Detachment Fault Determined From Crystallographic Preferred Orientation and Microstructure

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 6, June 2026.
Abstract At slow‐spreading mid‐ocean ridges large scale detachment faults partly accommodate the spreading process. The mafic and ultramafic rocks at the ridges are infiltrated by water and change their mineralogy. Subsequently or contemporaneously to these reactions, detachment faulting takes place.

Reactive Transport Modeling in Porous Fractured Media: Application to Weathering Processes

Water Resources Research
Complex permeability distribution is frequently encountered in weathered rocks with inherited heterogeneities, such as networks of discontinuities that impact fluid flow and water‐rock interactions.

Experimental study of the interaction of model garnet-harzburgite with H2O – CO2 – (K, Na)Cl fluids at 5 GPa and 1 100 °С

Vestnik MGTU
In modern petrological and geochemical literature, considerable attention is paid to the issue of the transformation of mantle rocks during their interaction with fluids and melts of various origins.

Syn‐ to Post‐Collisional Tectonic History of the Paleo‐Tethyan Orogenic Belt: Insights From Triassic Igneous Rocks in the North–Central Tibetan Plateau, China

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 6, June 2026.
Abstract The closure of the Paleo‐Tethys Ocean was one of the most important global geological events which formed the framework of the East Asian continent during the early Mesozoic. The Longmu Co‐Shuanghu suture zone is considered to record closure of the main basin of the Paleo‐Tethys Ocean.

Igneous sapphirine as a product of melt-peridotite interactions in the Finero Phlogopite-Peridotite Massif, Western Italian Alps

, 2013
Sapphirine is generally interpreted to be of metamorphic origin in high-MgO-Al2O3 rocks. Igneous sapphirine, i.e. sapphirine crystallised from melt, is very rare. We examined sapphirine-bearing magmatic veins in the Finero Phlogopite- Peridotite Massif,

Frictional melting of peridotite and seismic slip

Journal of Geophysical Research: Solid Earth, 2009
The evolution of the frictional strength along a fault at seismic slip rates (about 1 m/s) is a key factor controlling earthquake mechanics. At mantle depths, friction‐induced melting and melt lubrication may influence earthquake slip and seismological data.

Deep Origin and Shallow Launch for the Etna 122 B.C. Mafic Plinian Eruption

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 6, June 2026.
Abstract Basaltic Plinian eruptions challenge our understanding of explosive volcanism. The 122 B.C. Plinian eruption of Etna ranks among the most powerful mafic explosive events known. Here, we combine volatile barometry of 122 B.C. from olivine‐hosted melt and fluid inclusions with comparative data from the sub‐Plinian Fall Stratified eruption at ...

Transformation of Refractory Oceanic Lithospheric Mantle by Reactive Melt Infiltration: An Experimental Study on the Roles of Temperature, Melt Volume and Ascent Velocity

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 6, June 2026.
Abstract Reactive melt infiltration critically modifies the physical and chemical properties of the oceanic lithospheric mantle (OLM). This process, involving melt‐rock reactions and in situ crystallization, exhibits substantial spatial and temporal variability driven by melt volume and ascent velocity.

D‐Rex++: A New Tool to Simulate Olivine's Crystallographic Preferred Orientation in the Upper Mantle With Grain Size‐Coupled Rheology

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 6, June 2026.
Abstract Understanding the co‐evolution of olivine's crystallographic preferred orientation (CPO) and grain size is essential for capturing the dynamics of Earth's upper mantle. Existing CPO evolution models, such as D‐Rex, successfully predict CPO development but overpredict CPO strength and do not provide a physically meaningful grain size, limiting ...
