Thermal structure of continental subduction zone: high temperature caused by the removal of the preceding oceanic slab

Earth and Planetary Physics, 2021
The thermal structure of the continental subduction zone can be deduced from high-pressure and ultra-high-pressure rock samples or numerical simulation. However, petrological data indicate that the temperature of subducted continental plates is generally

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

, 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.

Sporadic low-velocity volumes spatially correlate with shallow very low frequency earthquake clusters

Nature Communications, 2017
In the Nankai subduction zone a low-velocity zone (LVZ) has been detected. Here, the authors present shear wave velocity profiles to show that low frequency earthquakes correlate with the distribution of the LVZ in the Nankai subduction zone.

Slow Geodynamics and Fast Morphotectonics in the Far East Tethys

Geochemistry, Geophysics, Geosystems, 2022
How can the sluggish, long‐wavelength mantle convection be expressed by so many time and space scales of morphotectonic activity? To investigate these relationships, we explore the Java‐Banda subduction zone, where geodynamic records cluster.

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

, 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.

P and S Wave Anisotropic Tomography of the Banda Subduction Zone

Geophysical Research Letters, 2023
In subduction zones with slab‐slab interactions, the pattern of mantle convection is very complex and still unclear. In this study, we jointly invert a large number of P and S wave arrival time data of local earthquakes for 3‐D isotropic and anisotropic ...

Subduction-zone parameters that control slab behavior at the 660-km discontinuity revealed by logistic regression analysis and model selection

Frontiers in Earth Science, 2022
The potential mechanisms that drive the behavior of subducted oceanic plates at the 660-km discontinuity are subject to debate. Here we conduct logistic regression analysis and model selection to determine the key subduction-zone parameters in natural ...

The Mesozoic Subduction Zone over the Dongsha Waters of the South China Sea and Its Significance in Gas Hydrate Accumulation

Journal of Marine Science and Engineering
The Mesozoic subduction zone over the Dongsha Waters (DSWs) of the South China Sea (SCS) is a part of the westward subduction of the ancient Pacific plate.

Bidirectional Loading of the Subduction Interface: Evidence From the Kinematics of Slow Slip Events

Geochemistry, Geophysics, Geosystems, 2020
Subduction zones host some of Earth's most damaging natural hazards, including megathrust earthquakes and earthquake‐induced tsunamis. A major control on the initiation and rupture characteristics of subduction megathrust earthquakes is how the coupled ...

Multiple Slabs and Complex Mantle Flows in the Molucca Sea Subduction Zone

Geochemistry, Geophysics, Geosystems
The Molucca Sea subduction zone is unique for its active divergent double‐subducted slab located in the north of the Java and Banda subduction zones. The spatial proximity of these subduction zones would cause a complex mantle flow field.
