The effect of sediment recycling in subduction zones on the Hf isotope character of new arc crust, Banda arc, Indonesia

Nebel, Oliver; Vroon, P.Z.; van Westrenen, Wim; Iizuka, Tsuyoshi; Davies, G R


A large portion of Earth's crust is formed at convergent plate boundaries that are accompanied by the subduction of sediments that can contain evolved crust-derived detritus. Partial melting of such sediments can strongly affect the trace element and isotope geochemistry of new arc rocks. Here, we present high-precision Lu-Hf-Zr concentration data and Hf isotope compositions for a series of volcanic rocks from the Banda arc, East Indonesia, to quantify the transfer of subducted Hf to the Banda...[Show more]
