Recycled oceanic gabbro produced the depleted component in hotspot magma from the Comei large igneous province in the Kerguelen mantle plume

Abstract Depleted components in hotspot magma sources remain enigmatic. Zircon δ18O values (3.97–4.80‰, average 4.38‰) from depleted gabbros in the Comei province (Kerguelen plume) are lower than mantle zircons, correlating negatively with 206Pb/U238ages. Combined with ultradepleted Hf isotopes, thi...
