1. Introduction. The Afar depression is a spectacular region that encompasses parts of Ethiopia, Eritrea and Djibouti ().This harsh and sparsely populated area marks the intersection of the southern Red Sea rift (RSR), the Gulf of Aden rift (GOA) and the Main Ethiopian Rift (MER), forming an archetypal rift-rift-rift triple junction [McKenzie et al., 1972; Tesfaye et al., 2003]. Slab-pull forces generated at the Zagros subduction zone strained the lithosphere in the Afro-Arabian plate, and dyking began to extend south from the Red Sea at c. 27 Ma, extending across Afar, fed by a plume-related magma source, rather than the rift-related source prevailing along the Red Sea.
