Chemical compositions of initial and residual silicate source glasses from degassing experiments: implications for Mars

Abstract

These files contain supporting data for the JGR manuscript Trace Element Transport and Deposition during Magmatic Degassing: The Effect on Martian Rocks and Fines. They report the chemical compositions (major oxides and volatiles) of initial and residual silicate source glasses from degassing and vapor-transport experiments. Composition (wt%) of major oxides calculated from EMPA (renormalized on a volatile-free basis); Cl and SO2 from EMPA (wt% based on total of oxides+Cl+SO2); wt% H2O calculated from micro-FTIR. Files include the raw EMPA and FTIR data, processing, and calculations used to obtain the chemical compositions presented in Table 5 of the manuscript
