Formation and evolution of a metasomatized lithospheric root at the motionless Antarctic plate: the case of East Island, Crozet Archipelago (Indian Ocean) [PDF]

open access: yes, 2016
Sitting atop the nearly stagnant Antarctic plate (ca. 6.46 mm/yr), the Crozet archipelago midway between Madagascar and Antarctica constitutes a region of unusually shallow (1543-1756 m below sea level) and thickened oceanic crust (10-16.5 km), high ...

Textures of Peritectic Crystals as Guides to Reactive Minerals in Magmatic Systems: New Insights from Melting Experiments [PDF]

open access: yes, 2012
International audiencePeritectic crystals in igneous rocks may be derived from either the source or country rocks, or may have formed by reactive assimilation of source-inherited solids, primary magmatic minerals during self- or magma mixing, or country ...

Mount Etna as a Leaking Pipe of Magmas From the Low Velocity Zone

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 4, April 2026.
Abstract Mount Etna, one of the most active volcanoes on Earth, exhibits unusual characteristics in terms of its geological setting, effusion rate, and volatile content. Mount Etna is closely related to the subduction of the Ionian plate below Eurasia, but, chemically, Mount Etna lavas are akin to intraplate magmatism.

Two-sided asymmetric subduction; implications for tectonomagmatic and metallogenic evolution of the Lut Block, Eastern Iran [PDF]

open access: yes, 2011
West directed subduction zones show common characteristics, such as low structural elevation, deep trench, steep slab and a conjugate back-arc basin that are opposite to those of the east directed subduction zones.

Decoding Metamorphic Nanodiamonds Formation Through Their Internal Structures

open access: yesJournal of Metamorphic Geology, Volume 44, Issue 3, Page 226-245, April 2026.
ABSTRACT Metamorphic diamonds offer insights into Earth's evolution, modulating the global carbon cycle through subduction into the mantle and exhumation. However, the formation and internal structure of minute diamonds remain poorly understood. Here, we study the internal structures of diamond‐bearing inclusions from the Eastern Alps using state‐of ...

Reconciling the shadow of a subduction signature with rift geochemistry and tectonic environment in Eastern Marie Byrd Land, Antarctica [PDF]

open access: yes, 2016
Basalt-trachyte volcanoes in the Marie Byrd Land (MBL) Cenozoic province lie along the Amundsen Sea coast on the north flank of the West Antarctic rift.

Atomically Thin Sieves: Two‐Dimensional Materials for Membrane Separation

open access: yesAdvanced Physics Research, Volume 5, Issue 3, March 2026.
Atomically thin membranes derived from 2D materials overcome the inherent selectivity‐permeability trade‐off in conventional separation technologies. This perspective elucidates transport mechanisms for gases, water, and ions, surveys fabrication strategies including top‐down pore engineering and bottom‐up synthesis, highlights recent experimental and ...

Rapid Slab Rollback Drives Early Cretaceous Back‐Arc Extension in NE China: Implication for Crustal Growth and Episodic Porphyry Mineralization

open access: yesGeochemistry, Geophysics, Geosystems, Volume 27, Issue 3, March 2026.
Abstract The subduction of the Paleo‐Pacific Plate beneath the NE Asian continental margin induced extensive magmatism, providing an excellent opportunity to investigate the interplay between plate dynamics, arc magmatism, continental crust formation, and porphyry mineralization.

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

open access: yesSoil & 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 ...
