Outline of Final Research Achievements

Recent findings of saline fluids from sub-arc mantle peridotite leads us to determine the effect of Cl on the trace element partitioning between aqueous fluids and melts. Synchrotron radiation X-ray fluorescence analysis is conducted to know trace elements partitioning between aqueous fluids and melts. Two slab-derived components, melt and fluid components, are suggested to explain trace element characteristics of arc-basalts. The fluid component is characterized by enrichment of alkali and alkali earth elements and can be explained if the fluid component is a saline fluid, because alkali earth elements and Pb are much less mobile with Cl-free fluids than Cl-rich fluids. Slab-derived components have compositional features consistent with a saline fluid and a melt, which can be formed through a separation of a slab-derived supercritical fluid. Slab-derived supercritical fluids contain Cl, and aqueous fluids inherit much of the Cl and some of the large-ion lithophile elements.
