Mantle dynamics in the Mediterranean [PDF]

open access: yesReviews of Geophysics, 2014
The Mediterranean offers a unique opportunity to study the driving forces of tectonic deformation within a complex mobile belt. Lithospheric dynamics are affected by slab rollback and collision of two large slowly moving plates forcing fragments of continental and oceanic lithosphere to interact.

Deep mantle anomalies block early Earth melting, challenging a primordial origin [PDF]

open access: yesScientific Reports
Earth’s deep mantle hosts enigmatic structures known as Large Low Velocity Provinces (LLVPs), which sit atop the core–mantle boundary and influence mantle dynamics and plume generation.

Multistage origin of dunite in the Purang ophiolite, southern Tibet, documented by composition, exsolution and Li isotope characteristics of constituent minerals [PDF]

open access: yesEuropean Journal of Mineralogy, 2020
The Purang ophiolite, which crops out over an area of about 650 km2 in the western Yarlung–Zangbo suture zone, consists chiefly of mantle peridotite, pyroxenite and gabbro.

Two new minerals, badengzhuite, TiP, and zhiqinite, TiSi2, from the Cr-11 chromitite orebody, Luobusa ophiolite, Tibet, China: is this evidence for super-reduced mantle-derived fluids? [PDF]

open access: yesEuropean Journal of Mineralogy, 2020
Titanium minerals enclosed in corundum separated from the Cr-11 orebody include native Ti, zamboite (FeTiSi2), osbornite (TiN)-khamrabaevite (TiC) solid solutions, and jingsuiite (TiB2), as well as the new minerals badengzhuite (TiP) and zhiqinite (TiSi2)

Cenozoic Dynamic Topography of Madagascar

open access: yesGeochemistry, Geophysics, Geosystems, 2021
It has been proposed that Oligo‐Miocene regional uplift of Madagascar was generated and is maintained by mantle dynamical processes. Expressions of regional uplift include flat‐lying Upper Cretaceous‐Paleogene marine limestones that crop out at ...

Thermomechanical modelling of lithospheric slab tearing and its topographic response

open access: yesFrontiers in Earth Science, 2023
Lithospheric slab tearing, the process by which a subducted lithospheric plate is torn apart and sinks into the Earth’s mantle, has been proposed as a cause for surface vertical motions in excess of 100 s of meters.

Mantle dynamics and seismic tomography [PDF]

open access: yesProceedings of the National Academy of Sciences, 2000
Three-dimensional imaging of the Earth's interior, called seismic tomography, has achieved breakthrough advances in the last two decades, revealing fundamental geodynamical processes throughout the Earth's mantle and core. Convective circulation of the entire mantle is taking place, with subducted oceanic lithosphere sinking into the lower mantle,

Narrow, Fast, and “Cool” Mantle Plumes Caused by Strain‐Weakening Rheology in Earth's Lower Mantle

open access: yesGeochemistry, Geophysics, Geosystems, 2022
The rheological properties of Earth's lower mantle are key for mantle dynamics and planetary evolution. The main rock‐forming minerals in the lower mantle are bridgmanite (Br) and smaller amounts of ferropericlase (Fp).

Linking deeply-sourced volatile emissions to plateau growth dynamics in southeastern Tibetan Plateau

open access: yesNature Communications, 2021
Deeply-sourced volatiles are releasing from orogenic plateau regions, providing windows to plateau growth dynamics occurring at variable depths.
