Contrasting behaviours of CO 2 , S, H 2 O and halogens (F, Cl, Br, and I) in enriched-mantle melts from Pitcairn and Society seamounts

Abstract

In order to improve characterisation of volatiles in the EM1 and EM2 mantle sources, which are interpreted to contain subducted sedimentary or lithospheric components, we report electron microprobe, FTIR and SIMS CO2, H2O, S, F and Cl concentrations of v
