A complex mantle plume head below East Africa‐Arabia shaped by the lithosphere‐asthenosphere boundary topography
Hot plumes rising from Earth's deep mantle are thought to cause uplift, rifting and large
igneous province (LIP) emplacement. LIP volcanism in continents often spans tens of Ma …

A common deep source for upper-mantle upwellings below the Ibero-western Maghreb region from teleseismic P-wave travel-time tomography
Upper-mantle upwellings are often invoked as the cause of Cenozoic volcanism in the Ibero-
western Maghreb region. However, their nature, geometry and origin are unclear. This study …

Asthenospheric Flow of Plume Material Beneath Arabia Inferred From S Wave Traveltime Tomography
Widespread Cenozoic volcanism in the Arabian Peninsula has been attributed to mantle
plume activity and/or lithospheric thinning due to rift‐related extension. However, there is …
