Geochemistry, Geophysics, Geosystems, 2021 Africa's Cenozoic tectonism is often attributed to mantle plumes, particularly below East Africa, but their morphology, number, location, and impact on the African lithosphere are debated.

Oceanic Slab Melting and Mantle Metasomatism [PDF]
Science Progress, 2001 Modern plate tectonic brings down oceanic crust along subduction zones where it either dehydrates or melts. Those hydrous fluids or melts migrate into the overlying mantle wedge trigerring its melting which produces arc magmas and thus additional continental crust. Nowadays, melting seems to be restricted to cases of young (<50 Ma) subducted plates.

The Temperature and Composition of the Mantle Sources of Martian Basalts
Geophysical Research Letters, 2023 The composition of basaltic melts in equilibrium with the mantle can be determined for several Martian meteorites and in‐situ rover analyses. We use the melting model MAGMARS to reproduce these primary melts and estimate the bulk composition and ...

CO2‐Rich Rejuvenated Stage Lavas on Hawaiian Islands
Geochemistry, Geophysics, Geosystems, 2022 Sedimentary carbonates are sent to the deep mantle if they are not completely destroyed at subduction zones, and subducted carbonates may contribute to plume volcanism.

The Relationship Between Kimberlitic Magmatism and Electrical Conductivity Anomalies in the Mantle
Geophysical Research Letters, 2022 Kimberlites are igneous rocks whose formation remains enigmatic due to their severely altered nature, highly variable compositions and rapid ascent through the lithosphere.

Geophysical Prospecting, Volume 74, Issue 7, September 2026.ABSTRACT Integrated earth modelling aims to combine all available geoscientific information to derive one common earth model. However, combining multiple parameters in a meaningful way remains challenging. In this study, we aim to improve mineral exploration workflows through the integration of new magnetotelluric data with other geophysical and ...
