The Accuracy Assessment of Lithospheric Density Models

Applied Sciences, 2023
The Earth’s synthetic gravitational and density models can be used to validate numerical procedures applied for global (or large-scale regional) gravimetric forward and inverse modeling.

Imaging a Decratonized Lithosphere: A Case of the Eastern North China Craton

Geophysical Research Letters, 2022
During decratonization, the cratonic lithosphere mantle experienced composition transformation and thinning, which have been extensively studied in the North China Craton.

Joint modeling of lithosphere and mantle dynamics elucidating lithosphere‐mantle coupling [PDF]

Geophysical Research Letters, 2008
We provide new insights into the lithosphere‐mantle coupling problem through a joint modeling of lithosphere dynamics and mantle convection and through comparison of model results with the high resolution velocity gradient tensor model along the Earth's plate boundary zones.

Craton Destruction Induced by Drastic Drops in Lithospheric Mantle Viscosity

Earth and Space Science, 2022
The disruption of the mantle roots of cratons is common after cratonization. Craton destruction, which is characterized by severe lithospheric thinning, extensive thrust and extensional deformation, basin filling, and intense thermal activities, is ...

Oceanic and super-deep continental diamonds share a transition zone origin and mantle plume transportation

Scientific Reports, 2021
Rare oceanic diamonds are believed to have a mantle transition zone origin like super-deep continental diamonds. However, oceanic diamonds have a homogeneous and organic-like light carbon isotope signature (δ13C − 28 to − 20‰) instead of the extremely ...

Refertilized continental root controls the formation of the Mianning–Dechang carbonatite-associated rare-earth-element ore system

Communications Earth & Environment, 2023
Rare earth element ore deposits associated with carbonatite derived from Earth’s mantle supply half of the world’s rare earth element. However, the formation of carbonatite and initial enrichment and transport of rare earth element in the mantle, is ...

Backarc Lithospheric Thickness and Serpentine Stability Control Slab‐Mantle Coupling Depths in Subduction Zones

Geochemistry, Geophysics, Geosystems, 2021
A key feature of subduction zone geodynamics and thermal structure is the point at which the slab and mantle mechanically couple. This point defines the depth at which traction between slab and mantle begins to drive mantle wedge circulation and also ...

Patched removal of the mantle lithosphere under orogens: A systematic numerical study

Frontiers in Earth Science, 2023
Delamination or convective thinning could cause large-scale and complete removal of the mantle lithosphere under orogens. However, geological and geophysical observations suggest that patched removal of the mantle lithosphere has occurred in some orogens,

Effects of Composite Rheology on Plate‐Like Behavior in Global‐Scale Mantle Convection

Geophysical Research Letters, 2023
Earth's upper mantle rheology controls lithosphere‐asthenosphere coupling and thus surface tectonics. Rock deformation experiments and seismic anisotropy measurements indicate that composite rheology (co‐existing diffusion and dislocation creep) occurs ...
