Metamorphic Dehydration, Fluid Pressure, and the Frictional‐Viscous Transition Along Subduction Megathrusts: Case Study in Cascadia and Implications for Slow Earthquakes

AGU Advances, Volume 7, Issue 3, June 2026.
Abstract Relative plate motion in subduction zones transitions from frictional slip to viscous flow with increasing depth and temperature. The frictional‐viscous transition can control the depth extent of megathrust earthquakes and episodic tremor and slip (ETS).

A neoproterozoic age for the chromitite and gabbro of the Tapo Ultramafic Massif, Eastern Cordillera, Central Peru, and its tectonic implications

, 2011
The ultramafic-mafic rocks of the Tapo Complex are exposed in the Eastern Cordillera of the Central Peruvian Andes. This complex is composed of serpentinised peridotites and metabasites with some podiform chromitite lenses and chromite disseminations and

Petrography and Geochemistry of Metasedimentary Rocks from the Taku Schist in Kelantan, North-East Peninsular Malaysia.

, 2021
The Taku Schist, which is located in the north-east Peninsular Malaysia, is characterized by its North-South oriented elongated body. It forms part of the Indonesian orogenic build-up that was generated via the convergence of the Sibumasu continental ...

Eastward Growth of the Tibetan Plateau Linked to Cenozoic Orogenic Wedge Deformation and Fluctuating Melt Sources

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 6, June 2026.
Abstract The India–Asia collision continuously loads the Tibetan Plateau (TP), driving its Cenozoic eastward growth. This process has caused extensive crustal deformation and a diverse magmatic response. Here, we report on newly identified 35−6.5 Ma granitoids from Kangding area in southeastern (SE) TP.

Hybridization between I-type and S-type granites in the ordovician famatinian magmatic arc, Tafí del Valle, Tucumán, NW Argentina

Geologica Acta, 2018
In the Tafí del Valle region, in northwestern Argentina, several intrusive bodies of lower Paleozoic age were emplaced in the metasedimentary Puncoviscana Formation, belonging to the Sierras Pampeanas. Four intrusive bodies outcrop in the study area: La

Middle Cretaceous Andean‐Type Arc Evolution in the Sanandaj–Sirjan Zone (Shalair Valley), Iraq: New Geochronological and Geochemical Constraints

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 6, June 2026.
Abstract The middle Cretaceous granitoid plutons of the Shalair Valley, situated in northeastern Iraq, constitute a principal magmatic component of the Sanandaj–Sirjan Zone within the northwestern segment of the Zagros Orogenic Belt. Among these plutons, the equigranular Aulan body (AG) and the porphyritic Laladar body (LG) were crystallized at 111.0 ±
