TL;DR: In this article, trace element and radiogenic isotope data have been measured on Oligocene flood basalts from the northwestern Ethiopian plateau to investigate and identify the nature of mantle and crustal sources involved in the genesis of this huge volume of prerift basalts to constrain the interaction between the Afar mantle plume and the lithosphere at the onset of continental break-up.

TL;DR: In this paper, a structural and stratigraphic framework for the southernmost Red Sea passive margin using new and existing 40 Ar/39 Ar age data along 6 transects is presented.

TL;DR: In this paper, the authors used trace element data to identify distinct geochemical groups and evaluate the role of differentiation processes in the discovery of low-Ti basalts in the Afro-Arabian CFB province.

TL;DR: In this paper, the authors synthesize ongoing seismic, structural, space-based geodetic, and petrologic studies from the subaerial Red Sea rift in Ethiopia where a major rifting episode commenced in September 2005.

TL;DR: The Ethiopian continental flood basalt (CFB) province as discussed by the authors was formed as the result of the impingement of the Afar mantle plume beneath the Ethiopian lithosphere, which includes major sequences of rhyolitic ignimbrites.
