- Abstract:
- High resolution stepped heating provides accurate and precise isotopic data for carbon in basaltic glass that can be employed to constrain and see through degassing histories to resolve pre-eruptive volatile compositions. A stepped heating system will be constructed to measure CO2 and H2O concentrations and delta 13C values in volcanic glasses from the Southeast Indian Ridge and the Kermadec arc. The data will be used to model the origin and evolution of carbon isotopic ratios. Analysis of densely sampled specimens will provide the most detailed picture yet of the degassing processes experienced by magmas in these two settings. In turn, this will provide a means to test several hypotheses regarding the provenance of volatiles and length-scale of carbon isotope heterogeneity in the mantle and the fluxes of carbon from and to the mantle.
