Description: These data correspond to the article “Hydrogen isotope behavior during rhyolite glass hydration under hydrothermal conditions” by Hudak et al. submitted to Geochimica et Cosmochimica Acta. Tables 1 and 2 are the data presented in the manuscript. Tables S1-S6 are the Supplementary Data. In addition to the csv data files, the formatted Supplementary Data files are provided in an Excel Workbook. This repository also includes our MATLAB code containing our isotope diffusion-reaction model.
Table 1 presents the initial geochemical compositions of the various rhyolitic glasses used in the hydration experiments.
Table 2 includes all experimental H2O and dD results.
Table S1 contains the list of rhyolitic glass hydration experiments, the materials used, and the experiment temperatures and durations.
Table S2 includes the water vapor and liquid water isotopic compositions for the isochoric experiments calculated from steam tables.
Table S3 presents energy-dispersive X-ray spectroscopy (EDX) data for spots on the surfaces of experimental glasses.
Table S4 contains Fourier transform infrared spectroscopy (FTIR) H2O concentration data for glasses produced in the rock mechanics experiments by Proctor et al. (2017).
Table S5 describes the parameters in our isotope diffusion-reaction model.
Table S6 presents the boundary conditions and assumptions used for the model results presented in the manuscript figures.

Table 1. Major element compositions of initial experimental glass as measured by EMPA, previously reported in the Supplementary Data of Bindeman and Lowenstern (2016) and Hudak and Bindeman (2020). The HSR is 08-YS-07 in Loewen et al. (2017) and the perlites are YS-13 in Bindeman and Lowenstern (2016). NBO/T ratios are calculated with normalized major element compositions. Totals reported here do not include Cl, F, or H2O. Yellowstone glasses use an Fe3+/Fetotal of 0.15 for an fO2 of NNO - 0.7 appropriate for hotspot settings. LSR calculations use an fO2 of NNO + 0.8 and an Fe3+/Fetotal of 0.25 appropriate for arc settings.
