- Abstract:
- I will measure Li isotopic compositions of back-arc volcanics to track spread of subducted materials away from the volcanic front. Lithium provides an unequivocal isotopic tracer of subducted input which can, however, only be transported short distances by fluids. Whether or not back-arc volcanics possess a heavy lithium isotopic signature will hence inform the manner of transport of subduction derived materials within the mantle wedge, by fluid migration or solid state convection. This will place first order constraints on the dynamics of destructive plate margins and provide key inputs for future physical models. Recent analytical developments make it possible to utilise this exceptional tracer for tackling this long-standing issue.
