Supplementary data for Hydrogen in natural inclusions: geological legacy or laboratory artifact

This dataset includes numerical data supporting the figures and tables in the manuscript entitled "Hydrogen in natural inclusions: geological legacy or laboratory artifact?". It contains Raman spectra collected before and after hydrogen production in systems containing bitumen, diamond or graphite; original and processed data for temperature calibration curves and reaction rate analyses; and results from quantitative analyses of fluid inclusion compositions. Additional files include hydrogen preservation time estimates in mineral-hosted inclusions, spectra related to hydrogen production from dolomite, ethane consumption spectra, and Raman spectra acquired under varying laser power to determine hydrogen production thresholds. All files are provided in text-based formats (.txt or .xlsx) to ensure transparency and reproducibility. These data support both the main article and the supplementary material.
