TL;DR: In this paper, geochronological (40Ar/39Ar) and magnetostratigraphic results for the Ethiopian traps, one of the last remaining flood basalts for which few such data were available, were presented.

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, 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 present new helium isotopic measurements that, added to existing data, allow them to restrict the spatial extent of a high-3He component (up to 20 Ra) to the Ethiopia-Afar volcanic province, for places where large volumes of Oligocene pre-rift flood basalts and ignimbrites erupted within a short (1-2 Ma) time interval.

TL;DR: In this article, the authors presented (U-Th)/He thermochronological data from the Longmen Shan belt, eastern Tibet, and performed forward modeling of their data to derive quantitative information on the exhumation of the range.
