Lithium concentrations and isotopic compositions of olivine and Sr/Sr and Nd/Nd of coexisting clinopyroxene from peridotite xenoliths from the Quaternary Labait volcano, Tanzania, document the influence of rift-related metasomatism on the ancient cratonic mantle. Olivines show negative correlations between Fo content and both dLi and Li concentrations. Olivines in iron-rich peridotites (Fo85–87) have high Li concentrations (3.2–4.8 ppm) and heavy dLi (+5.2 to +6.6). In contrast, olivines in… CONTINUE READING
