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.

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 ...

Metasomatized lithospheric mantle for Mesozoic giant gold deposits in the North China craton [PDF]

, 2020
The origin of giant lode gold deposits of Mesozoic age in the North China craton (NCC) is enigmatic because high-grade metamorphic ancient crust would be highly depleted in gold.

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 ...

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.

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 ...

A Comparison of Gravimetric, Isostatic, and Spectral Decomposition Methods for a Possible Enhancement of the Mantle Signature in the Long-Wavelength Geoidal Geometry

Remote Sensing, 2023
A long-wavelength geoidal geometry characterizes the most pronounced features of the Indian Ocean geoid low and the West Pacific and North Atlantic geoid highs.

Making Cratonic Lithospheric Mantle [PDF]

Journal of Geophysical Research: Solid Earth, 2018
AbstractThe origin of cratonic lithospheric mantle has been attributed to either high‐pressure (5–7 GPa) melting in hot mantle plumes or low‐pressure (<5 GPa) melting in mid‐ocean ridges or suprasubduction zones. To resolve this long‐standing debate, it is necessary to confirm under what depths the incipient cratonic mantle melted.

African cratonic lithosphere carved by mantle plumes [PDF]

Nature Communications, 2020
AbstractHow cratons, the ancient cores of continents, evolved since their formation over 2.5 Ga ago is debated. Seismic tomography can map the thick lithosphere of cratons, but its resolution is low in sparsely sampled continents. Here we show, using waveform tomography with a large, newly available dataset, that cratonic lithosphere beneath Africa is ...
