New paper out in Gcubed - Feb 2021. In this paper we use the AFRP20 tomographic model to depth convert receiver functions to investigate the impact of multiple upwellings below the African continent on mantle transition zone discontinuities. We find a thin transition zone underlies East African Cenozoic magmatism implying influence of processes at mantle transition zone depths or below. We suggest that a thermochemically distinct upwelling underlies Kenya while a purely thermal upwelling underlies Ethiopia.
