Reproducing past subduction and mantle flow using high-resolution global convection models

Earth and Planetary Physics, 2018
Plate subduction drives both the internal convection and the surface geology of the solid Earth. Despite the rapid increase of computational power, it remains challenging for geodynamic models to reproduce the history of Earth-like subduction and ...

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.

Azimuthal anisotropy beneath north central Africa from shear wave splitting analyses

Geochemistry, Geophysics, Geosystems, 2015
This study represents the first multistation investigation of azimuthal anisotropy beneath the interior of north central Africa, including Libya and adjacent regions, using shear wave splitting (SWS) analysis.

Insights Into the Nature of Plume‐Ridge Interaction and Outflux of H2O From the Galápagos Spreading Center

Geochemistry, Geophysics, Geosystems, 2021
The flow of high‐temperature and compositionally enriched material between mantle plumes and nearby spreading centers influences up to 30% of the global mid‐ocean ridge system and represents a significant, but currently unconstrained, flux of volatiles ...

Mantle upwelling induced by slab rollover subduction could explain widespread intraplate volcanism in Tibet

Communications Earth & Environment
Subduction-induced mantle flow has a considerable geodynamic impact on Earth. It can deflect mantle plumes, transport geochemical signatures and produce upwellings that generate atypical intraplate volcanism.

Seismic evidence for the existence of an entrained mantle flow coupling the northward advancing Indian plate under Tibet

Earth and Planetary Physics, 2019
The Tibetan Plateau, known as “the roof of the world” and “the third pole of the earth”, is a product of the collision between India and Asia during the last ~50 Ma.

Convergent mantle flow and plate kinematics contribute to South China Sea rifting

Nature Communications
Continental rifting in marginal seas remains debated, particularly regarding the role of mantle dynamics in lithospheric extension. The South China Sea, the largest marginal sea in the western Pacific, provides a well-constrained case for exploring this ...

The Sensitivity of Joint Inversions of Seismic and Geodynamic Data to Mantle Viscosity

Geochemistry, Geophysics, Geosystems, 2020
Seismic tomography has revealed the existence of large‐scale velocity heterogeneities in the mantle. The interpretation of seismic velocity anomalies in terms of temperature and chemical composition is nonunique.
