A complex mantle plume head below East Africa‐Arabia shaped by the lithosphere‐asthenosphere boundary topography

C Civiero, S Lebedev, NL Celli - Geochemistry, Geophysics …, 2022 - Wiley Online Library
Hot plumes rising from Earth's deep mantle are thought to cause uplift, rifting and large

Role of Large Igneous Provinces in continental break-up varying from “Shirker” to “Producer”

A Koptev, S Cloetingh - Communications Earth & Environment, 2024 - nature.com
Traditionally, the emplacement of the Large Igneous Provinces (LIPs) is considered to have
caused continental break-up. However, this does not always seem to be the case, as …
