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.

Comments
EMPA (electron microprobe analyses) of source and residual glasses were performed at the American Museum of Natural History using a Cameca SX5-Tactis electron microprobe; FTIR (Fourier Transform Infrared spectroscopy) were conducted at the Center for Planetary Exploration at Stony Brook University using a Nicolet iN10MX imaging spectrometer. Further analytic details are in the attached files and/or the full manuscript.
