Convergent mantle flow and plate kinematics contribute to South China Sea rifting [PDF]
Nature CommunicationsContinental 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 ...

Modulation of intra-oceanic trench bending and along-trench thermochemical transport by mantle toroidal flow [PDF]
Nature CommunicationsOceanic trench bending over 1000 km occurs globally, with notable along-trench variations in mantle wedge thermochemistry. However, the mechanisms influencing both shallow trench geometry and deep mantle state remain unclear. Here we focus on the Mariana

The Osmium Isotope Signature of Phanerozoic Large Igneous Provinces
Geophysical Monograph Series, Page 229-246., 2021 Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Upper-plate Shortening and Mountain-building in the Context of Mantle-driven Oceanic Subduction
Tektonika, 2023 The mechanisms controlling mountain building at subduction zones remain debated. In particular the interaction between mantle flow and subduction has been poorly addressed while fundamental in controlling plate displacement and deformation.

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 ...

Convective Self‐Compression of Cratons and the Stabilization of Old Lithosphere
Geophysical Research Letters, 2023 Despite being exposed to convective stresses for much of the Earth's history, cratonic roots appear capable of resisting mantle shearing. This tectonic stability can be attributed to the neutral density and higher strength of cratons. However, the excess

Geophysical Research Letters, 2021 Heat flow measurements are important for our understanding of planetary interior composition, structure, and evolution. In the absence of direct measurement, a first‐order estimate of a planet's interior heat flow can be made by modeling the lithosphere ...

The deep Earth origin of the Iceland plume and its effects on regional surface uplift and subsidence [PDF]
Solid Earth, 2017 The present-day seismic structure of the mantle under the North Atlantic Ocean indicates that the Iceland hotspot represents the surface expression of a deep mantle plume, which is thought to have erupted in the North Atlantic domain during the ...
