Data for: Effects of pH2O, pH2 and fO2 on the diffusion of H-bearing species in lunar basalt and an iron-free basaltic analog at 1 atm
This file contains supplementary calculations and data in support of the manuscript "EFFECTS OF pH2O, pH2 AND fO2 ON THE DIFFUSION OF H-BEARING SPECIES IN LUNAR BASALT AND AN IRON-FREE BASALTIC ANALOG AT 1 ATM", submitted to Geochimica et Cosmochimica Acta. The authors of the manuscript are: M.E. Newcombe*, J.R. Beckett, M.B. Baker, S. Newman, Y. Guan, J.M. Eiler, and E.M. Stolper * email@example.com CONTENTS 1. Run Table: Description of experimental setup and conditions 2. Gas composition from emf: Calculation of partial pressures of H2, CO2, CO, O2, and H2O in the furnace hotspot from the voltage difference measured by the oxygen sensor 3. Gas composition from flow rates: Calculation of partial pressures of H2, CO2, CO, O2, and H2O in the furnace hotspot from measured flow rates of CO2 and H2 4. Results Table: Extended table of fitting results and diffusion model parameters 5. Solubility relationship check: Calculations of the expected water concentration at the melt-vapor interface and interior of each experiment (based on solubility relationships reported by Newcombe et al. 2017) and measured water concentration at the melt-vapor interface and interior of each experiment Worksheets #6 onwards contain raw and processed SIMS data, and best-fit water diffusion model profiles for each experiment.
