Petrological constraints on evolution of continental lithospheric mantle beneath the northwestern Ethiopian plateau: Insight from mantle xenoliths from the Gundeweyn area, East Gojam, Ethiopia

Based on our data, we conclude that the lithospheric mantle beneath Gundeweyn has experienced melt extraction during and/or before pan-African orogeny and then interacted with various degrees of asthenospheric melt. The interaction is probably related to mantle upwelling, which is mainly focused beneath East Africa rift system (EARS).
