Earlier work by the PI and other investigatiors suggest that                    boron isotopes may be valuable and unique tracers of fluids                     derived during dehydration of the subducting slab at island arcs.               This project will study the extent of lithosphere recycling back                into the mantle as expressed in inter-oceanic island are basalts                using boron as a tracer.  Approximately 40 samples from the                     Halmahera arc have already been subjected to extensive                          petrologic, geochemical and isotopic analysis, and these will be                used for the boron studies.  This work is expected to confirm the               usefulness of boran as a tracer, and to shed new light on the                   role of fluids from the subducting slab.
