Melt inclusions, volatile fluxes and halogen cycling through Island Arcs

A suite of volatiles including H2O, CO2, F, Cl, Br and I will be measured in olivine hosted melt inclusions and related arc lavas.  The samples will be selected from existing collections or collected during fieldwork, depending on the students interests.  The project will utilise a range of techniques including electron microprobe and laser ablation ICPMS and an important aim will be to demonstrate precise measurements of trace halogens (Br and I) by ion microprobe, with complementary data obtained by ‘the noble gas method’. The data will be used to evaluate the subduction flux of halogens into the mantle.
