Pb-isotopic evidence for rapid trench-parallel mantle flow beneath Vanuatu

Heyworth, Z; Knesel, Kurt Michael; Turner, Simon; Arculus, Richard


Abstract: Recent geophysical and geochemical studies suggest that some subduction zones have a significant component of trench-parallel flow that is difficult to reconcile with conventional 2D corner-flow models. Mapping of different mantle Pb-isotopic signatures provides an opportunity to assess the role of along-strike flow beneath the Vanuatu region. Young back-arc spreading centres in the southern segment of the subduction zone have high 208Pb/ 204Pb for a given 206Pb/ 204Pb, similar to the...[Show more]
