Edge‐Driven Convection Melting Before the Emplacement of the Afar Mantle Plume Head Inferred From 40Ar/39Ar Dating

Abstract The Ethiopia‐Yemen flood basalts are spatially zoned with progressively lower TiO2 lavas from near the Afar depression toward the margins. The timing and rate of emplacement of low TiO2 (LT) lavas are poorly known compared with the ultra‐high TiO2 (HT2) lavas. We measured two high‐precision...
