Photochemistry of Fe (II) and Carbonate-bearing Waters and the Influence on Greenhouse Gas Production in Early Mars

"GC_Data" Folder contains the gas chromatography dataset obtained for all of the experiments discussed in this work. The files are titled using the format GC_ExperimentName utilizing the same experiment names in the paper. Each file is in an .xlsx format that each contain the sample measurements in different sheets and the sheets are identified with the time in minutes of sample collection. "Mineralogy" Folder contains the ATR-FTIR and XRD datasets for the four experiments that had these measurements. Each file is in an .xlsx format and is identified with the experiment names used in the paper. "ExperimentResults" is an .xlsx file that has the values for pHi, pHf, Fei, Fef, ICP-OES/MS (specifies which instrument was used for each experiment), final solution color, and hydrogen produced for each experiment with their respective uncertainties. "pCO2_H2perFe" is an .xlsx file that has the values for pCO2 and H2/Fe ratio for each experiment shown in Figure 7 of the main text. "SM_GasPeakIntensity" is a .xlsx file that contains the values for the GC peak heights for hydrogen and methane from each expeirment that is shown in the supplementary material, section SM7 (Figure S8). "SM_TOC" is an .xlsx file with the total organic carbon results for the DI water samples that were measured.
