SP12RTS: a degree-12 model of shear-and compressional-wave velocity for Earth's mantle
We present the new model SP12RTS of isotropic shear-wave (VS) and compressional-wave
(VP) velocity variations in the Earth's mantle. SP12RTS is derived using the same methods …

On the relationship between volcanic hotspot locations, the reconstructed eruption sites of large igneous provinces and deep mantle seismic structure
It has been proposed that volcanic hotspots and the reconstructed eruption sites of large
igneous provinces (LIPs) are preferentially located above the margins of two deep mantle …

Retrodictions of Mid Paleogene mantle flow and dynamic topography in the Atlantic region from compressible high resolution adjoint mantle convection models …
L Colli, S Ghelichkhan, HP Bunge, J Oeser - Gondwana Research, 2018 - Elsevier
Although mantle convection at Earth-like vigor is a chaotic process, it has been shown by
conceptual studies that one can constrain its flow history back in time for periods …

Rapid South Atlantic spreading changes and coeval vertical motion in surrounding continents: Evidence for temporal changes of pressure‐driven upper mantle flow
Abstract The South Atlantic region displays (1) a topographic gradient across the basin, with
Africa elevated relative to South America,(2) a bimodal spreading history with fast spreading …
