Abstract

Cruise SO255 of the German Research Vessel SONNE surveyed the Kermadec Arc System from ca 35°S to 28°S in 2017. Volcanic rocks were obtained by dredge from the Neogene Colville and Kermadec ridges that represent the split remnants of the preceding Vitiaz Arc, the Havre Trough backarc and Quaternary volcanic centers of the Kermadec Arc. The overarching goal of SO255 "VITIAZ" is to elucidate the physical and chemical conditions that control the development of subduction zones, including evolution of mature arc systems, and the transition from arc splitting to back-arc basin generation. The correlated dataset reports major element data for 317 samples, trace element data for 285 samples, radiogenic Sr-Nd-Pb isotope ratios for 155 samples and radiogenic Hf isotope ratios for 88 samples. These include eight topic related samples of cruises TAN0206, TAN1611 of the New Zealand research vessel TANGAROA and one sample of cruise B30 of the Russian research vessel VOLCANOLOG.
