Abstract:
We have determined the Ti isotope composition of well-characterized, subduction-related basalts, andesites and boninites. Samples from the Solomon Islands, the Troodos ophiolite in Cyprus, and Cape Vogel in Papua New Guinea show small but resolvable variations, that may be related to differences in their mantle sources. Our study highlights that the combination of diagnostic trace element patterns, and Ti isotope compositions in subduction-related igneous rocks can be a powerful tool to constrain petrogenetic processes and to discriminate between different crystallizing mineral phases.
