Abstract

A series of experiments was conducted to examine the capacity of H2O fluids to concentrate and transport incompatible elements (including Rb, Sr, Ba, Y, Zr, Hf, Nb, Ta, La, Lu, Th and U) in the peridotitic mantle and subducted ocean crust. An electron microprobe and proton microprobe were used to measure concentrations of major and trace elements in solutes from aqueous fluids equilibrated (at 900-1100°C, 2.0 GPa) with water-saturated melts of trondhjemitic and basanitic composition. The compositions of co-existing mineral phases (including staurolite, amphibole and clinopyroxene) were also determined. Solutes in equilibrium with both trondhjemitic and basanitic melts have granitic compositi..
