TL;DR: The Ethiopian plateau is made up of several distinct volcanic centres of different ages and magmatic affinities as discussed by the authors, and the three main types of magma have very different major and trace element characteristics ranging from compositions low in incompatible elements in the tholeiites [e.g. 10 ppm La at 7 wt % MgO (=La7), La/εb = 4.2], moderate in the alkali basalts (La7 = 24, La/β = 9.2), and very high in the magnesian alkaline magmas (

TL;DR: The spinel lherzolite enclaves contain variable proportions of olivine, orthopyroxene, green clinopyroxenes and brown spinel, and have undergone deformation and partial recrystallization as discussed by the authors.
