New high-density sampling of the Eastern Lau Spreading Center provides constraints on the processes that affect the mantle wedge beneath a back-arc environment. PetDB MORB data provide a compositional range for typical mid-oceanic ridges and allow to distinguish the effect of the subduction input on back-arc basalt petrogenesis and the change in subduction input with distance from the Tonga arc.
