Basalt and sediment geochemistry and magma petrogenesis in a transect from oceanic island arc to rifted continental margin arc: The Kermadec Hikurangi Margin, SW Pacific

Sediment mixing and recycling through a subduction zone can be detected in lead isotopes and trace elements from basalts and sediments from the Kermadec-Hikurangi Margin volcanic arc system and their coupled back-arc basins. Sr, Nd and Pb isotopes from the basalts delineate relatively simple, almost overlapping, arrays between back-arc basin basalts of the Havre Trough-Ngatow Basin (^Sr/^Sr^ island arc basalts from the Kermadec Arc together with basalts from Taupo Volcanic £one ("'Sr/^Sr 38-61), and sediments derived from New Zealand's Mesozoic (Torlesse) basement 38-8). Basalts from the arc front volcanoes have high Cs, Rb, Ba, Th, U and K, and generally high but variable Ba/La, tinental derived sediment into the sediment-starved oceanic trench system. The trace element and isotopic signatures of the continental derived component of this sediment are readily dis-tinguished, but also diluted in a south to north direction along the plate boundary.
