High-pressure high-temperature experimentsExperimental details (e.g., pressure, temperature, starting fluid composition) with numbers of experimental capsules are provided in an Excel file.Raman spectroscopyThe name of each txt file with a Raman spectrum contains the acquisition parameters, the number of experimental capsule the measured SFI belongs to, the temperature at which the spectrum was collected and a letter corresponding to the phase that was measured: H for host, F for liquid, G for vapour, and SF for supercritical fluid.LA-ICP-MSAll individual analyses with average values and standard deviations for each group of SFI are provided in an Excel file.
