Statement: Table 2: δ18O analysis of glass and mineral separates was carried out at Scottish Universities Environmental Research Centre, East Kilbride by laser fluorination modified for ClF3. For mineral separates, overnight prefluorination was carried out to remove adsorbed environmental water from the sample chamber and line. For glasses, which are more reactive in ClF3, we employed a short room-temperature prefluorination before each analysis. Table S4:Manda Hararo Rift Segment and Badi samples were analysed at Woods Hole Oceanographic Institution (WHOI), USA, using a ThermoFinnigan Neptune MC-ICP-MS. Dabbahu samples were analysed at NERC Isotope Geosciences Laboratory , UK, using a Thermo Scientific Triton mass spectrometer operating in multi-dynamic mode.
