Ductile Extrusion Triggered by Continental Collision in NE Brazil
Terra Nova, Volume 38, Issue 4, Page 266-277, August 2026.ABSTRACT The Borborema Province in northeastern Brazil hosts one of the world's largest strike‐slip shear zone networks, active during the late Neoproterozoic assembly of West Gondwana. Whether these shear zones initiated during active continental collision or as a post‐orogenic response to far‐field stresses remains debated.

Garnet-Amphibolites Mineralogy and thermobarometry in Aliabad-Damagh (south of Hamedan, Sanandaj-Sirjan Zone) [PDF]
پترولوژی, 2017 The garnet-amphibolites in Aliabad-Damagh area, occurs as layers and are enveloped by staurolite-schist. They composed predominantly of garnet, hornblende, feldspar (± muscovite and quartz) with titanite, epidote, ilmenite and graphite as accessory ...

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 7, July 2026.Abstract Predicting the partial melting conditions that generate Li‐rich peraluminous melts is of major economic and societal importance. However, existing models disagree on the optimal conditions (e.g., pressure, temperature, protolith) and, consequently, on targets for exploration.

Tectonics, Volume 45, Issue 7, July 2026.Abstract The accretion of allochthonous provinces, derived from oceanic plates, has traditionally been considered an important contributor to continental growth. However, increasing evidence shows that some oceanic terranes (e.g., island arcs) are not “exotic,” as suggested by the presence of continental‐derived sedimentary provenance.

Tectonics, Volume 45, Issue 7, July 2026.Abstract Serpentinite plays a major role in the geodynamics of subduction zones. However, the processes by which serpentinite is incorporated into accretionary complexes, and the extent to which it interacts chemically and physically with accretionary lithologies, remain unclear.

Tectonics, Volume 45, Issue 7, July 2026.Abstract Syros island preserves pristine high‐pressure metamorphic rocks and provides invaluable insight into subduction zone processes. Contrasting views on the structural history impede placing the island in a clear tectonic framework, limiting the broader impact of preserved information.

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 7, July 2026.Abstract Exhumed metamorphic rocks yield critical insights into the mechanical, chemical, and thermal structure of the plate interface that can be used to infer exhumation pathways and their evolution throughout a subduction zone's lifetime. Metamorphosed oceanic rocks often record exhumation and underplating over relatively punctuated time periods ...
