Complex anisotropy beneath the Peruvian flat slab from frequency-dependent, multiple-phase shear wave splitting analysis [PDF]

open access: yes, 2013
Flat or shallow subduction is a relatively widespread global occurrence, but the dynamics remain poorly understood. In particular, the interaction between flat slabs and the surrounding mantle flow has yet to be studied in detail.

The physics of a small-scale tearing mode in collisionless slab plasmas [PDF]

open access: yesPlasma Physics and Controlled Fusion, 2020
Abstract Microtearing modes have been widely reported as a tearing parity electron temperature gradient driven plasma instability, which leads to fine scale tearing of the magnetic flux surfaces thereby resulting in reconnection of magnetic field lines and formation of magnetic islands.

Tectonic significance of changes in post-subduction Pliocene-Quaternary magmatism in the south east part of the Carpathian-Pannonian Region [PDF]

open access: yes, 2010
The south-eastern part of the Carpathian–Pannonian region records the cessation of convergence between the European platform/Moesia and the Tisza–Dacia microplate.

El uso de materias colorantes en el Paleolítico superior de la cueva de Lumentxa (Lekeitio, Bizkaia, Norte de la Península Ibérica) [PDF]

open access: yesMunibe Antropologia-Arkeologia, 2021
El ocre es un material colorante utilizado desde épocas antiguas por los cazadores-recolectores de todo el planeta. Estudiamos 34 objetos recuperados en los niveles magdalenienses de la cueva de Lumentxa durante las intervenciones de los años veinte del ...

Evolution of tear faults in subduction zones: an analogue modelling perspective [PDF]

open access: yes, 2020
Tear faults are common structures in subduction zones, especially at slab edges, where they origin from differential forces applied to a subducting slab in areas close to the trench.

Control of slab tears and slab flat wedging on volcanism in the Alaska subduction zone. [PDF]

open access: yesSci Rep
Abstract Multistage plate subduction plays a crucial role in magmatism; however, the mechanisms by which deep geodynamic processes govern volcanism in the Alaska subduction zone remain controversial. In this study, we revealed that the Pacific Plate transitioned from oblique subduction along the Aleutian volcano chain to lower-angle subduction ...

Vanadium microalloyed steel for thin slab casting and direct rolling [PDF]

open access: yes, 2005
Vanadium microalloyed steels with high yield strength (»600 MPa), good toughness and ductility have been successfully produced in commercial thin slab casting plants employing direct rolling after casting.

Control of Upstream Austenite Grain Coarsening during the Thin-Slab Cast Direct-Rolling (TSCDR) Process

open access: yesMetals, 2019
Thin-slab cast direct-rolling (TSCDR) has become a major process for flat-rolled production. However, the elimination of slab reheating and limited number of thermomechanical deformation passes leave fewer opportunities for austenite grain refinement ...

The geodynamic origin of Los Humeros volcanic field in Mexico: insights from numerical simulations

open access: yesScientific Reports, 2023
Compared to normal arc-related volcanic eruptions, the formation of a volcanic caldera is a relatively atypical event. During caldera formation a series of large volumes of magma are erupted, reducing the structural support for the rock above the magma ...

DEVONIAN-CARBONIFEROUS MAGMATISM AND METALLOGENY IN THE SOUTH URAL ACCRETIONARY-COLLISIONAL SYSTEM

open access: yesГеодинамика и тектонофизика, 2021
The oceanic stage in the history of the South Urals completed in the Ordovician – Early Silurian. The Ordovician through Devonian events in the region included the formation of an island arc in the East Ural zone from the Middle Ordovician to Silurian ...
