Coesite Discovery in Eclogites Confirms UHP Metamorphism in the Orlica‐Śnieżnik Dome (SW Poland)

open access: yesJournal of Metamorphic Geology, Volume 44, Issue 3, Page 200-225, April 2026.
ABSTRACT Eclogite lenses are exposed within the orthogneiss‐dominated core of the Orlica‐Śnieżnik Dome in the Sudetes, which forms the northeastern margin of the Bohemian Massif (Variscan Belt of Central Europe). The presence of coesite inclusions in garnet and omphacite confirms that these eclogites underwent ultrahigh‐pressure metamorphism.

Cooling‐Induced Rheological Weakening Along the Nascent Plate Interface—A Mechanism for Catastrophic Subduction Initiation?

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 1, January 2026.
Abstract Subduction initiation often begins with slow, forced convergence, switches “on” catastrophically as the slab collapses into the mantle, and then evolves to steady‐state, self‐sustained sinking that drives global plate movements. Numerical models suggest that the collapse phase implies sudden weakening of the plate interface.

The Transition From Melt Accumulation to Eruption Initiation Recorded by Orthopyroxene Fe‐Mg Diffusion Timescales in Late Holocene Rhyolites, South Sister Volcano, Oregon Cascade Range

open access: yesGeochemistry, Geophysics, Geosystems, Volume 26, Issue 12, December 2025.
Abstract South Sister volcano, Oregon Cascade Range, USA, has repeatedly erupted rhyolite since ca. 40 ka. The youngest such eruptions are the ca. 2 ka Rock Mesa and Devils Chain rhyolites, erupted several hundred years apart from two multi‐vent complexes separated by 3–6 km. Fe‐Mg interdiffusion models of orthopyroxene rims from both rhyolites produce

Génesis de arcillas magnésicas en la cuenca de Madrid: interrogantes planteados [PDF]

open access: yes, 2004
La cuenca de Madrid es excepcionalmente rica en arcillas magnésicas (sepiolita, paligorskita, saponita y estevensita), las cuales para formarse requieren elevada actividad de silicio y magn esio, a la vez que pH alcalinos, siendo típicas de medios ...

Can Multiphase Inclusions in Garnet From Eclogite Facies Rocks Be a Product of Melt or Supercritical Fluid Entrapment During Subduction?

open access: yesJournal of Metamorphic Geology, Volume 43, Issue 9, Page 891-908, December 2025.
ABSTRACT Dehydration of rocks and minerals during high‐pressure metamorphism is controlled by the thermal structure of the subduction zone and can be traced by the stability fields of hydrous phases. Consistent with the results of experimental works, the content of silicate components in fluids is assumed to increase from the fields of subcritical to ...

Radiogenic Heating as the Thermal Driver of Himalayan Crustal Heating During Prolonged Thickening

open access: yesGeochemistry, Geophysics, Geosystems, Volume 26, Issue 11, November 2025.
Abstract The thermal evolution of the crust during continental collision evolves from cold to hot with time, which impacts crustal reworking and differentiation. However, it remains elusive as to the mechanism driving the crust to be hot during the protracted collision.
