Adjoint traveltime tomography unravels a scenario of horizontal mantle flow beneath the North China craton

Scientific Reports, 2021
The North China craton (NCC) was dominated by tectonic extension from late Cretaceous to Cenozoic, yet seismic studies on the relationship between crust extension and lithospheric mantle deformation are scarce.

Plume-Induced Subduction Initiation: Revisiting Models and Observations

Frontiers in Earth Science, 2021
Subduction initiation induced by a hot and buoyant mantle plume head is unique among proposed subduction initiation mechanisms because it does not require pre-existing weak zones or other forces for lithospheric collapse.

Mantle Anisotropy in NW Namibia From XKS Splitting: Effects of Asthenospheric Flow, Lithospheric Structures, and Magmatic Underplating

Geophysical Research Letters, 2023
The presence of the Etendeka flood basalts in northwestern Namibia is taken as evidence for the activity of the Tristan da Cunha mantle plume during the continental breakup between Africa and South America.

Seismological structure of the Carpathian-Pannonian region of central Europe [PDF]

, 2010
The extensional Pannonian Basin is set within the convergent arc of the Alpine-Carpathian mountain system in central Europe. Various models have been proposed as mechanisms to drive extension within this collisional setting.

Plume-subduction interaction forms large auriferous provinces

Nature Communications, 2017
The lithospheric controls on giant gold deposits remain unclear. Here, the authors show evidence for native gold in the mantle from the Deseado Massif in Patagonia demonstrating that refertilisation of the lithospheric mantle is key in forming ...

Geochemistry and tectonic development of Cenozoic magmatism in the Carpathian–Pannonian region [PDF]

, 2011
This review considers the magmatic processes in the Carpathian–Pannonian Region (CPR) from Early Miocene to Recent times, as well as the contemporaneous magmatism at its southern boundary in the Dinaride and Balkans regions.

Lithospheric deformation and mantle dynamics beneath the eastern North American Margin from frequency-dependent shear wave splitting analyses

, 2023
Lynner, ColtonConstraints on the relative contributions of lithospheric and asthenospheric seismic anisotropy along the eastern passive margin of North America are necessary to further our understanding of past tectonics and current mantle dynamics ...

Coupled Evolution of Plate Tectonics and Basal Mantle Structure

Geochemistry, Geophysics, Geosystems, 2021
The relationships between plate motions and basal mantle structure remain poorly understood, with some models implying that the basal mantle structure has remained stable over time, while others suggest that it could be shaped by the aggregation and ...

Mafic alkaline metasomatism in the lithosphere underneath East Serbia: evidence from the study of xenoliths and the host alkali basalts [PDF]

, 2010
Effects of mafic alkaline metasomatism have been investigated by a combined study of the East Serbian mantle xenoliths and their host alkaline rocks.
