The role of continental lithosphere metasomes in the production of HIMU-like magmatism on the northeast African and Arabian plates
Intraplate alkaline lavas typically exhibit isotopic characteristics that require a source with
long-term isolation from the convecting asthenosphere, such as in the sub-continental
lithosphere mantle or a mantle boundary layer. Melting of metasomatically enriched
domains, or metasomes, within the lithospheric mantle provides a viable mechanism for
generating the geochemical characteristics of intraplate alkaline basalts. The origins and
distribution of these metasomes have been attributed to recent enrichment of the lithosphere …
