Supplementary Data for "An expansive global oxygenation of Earth's surface environments 1.4 billion years ago":Geochemical Dataset and Model Parameters

Supplementary Table 1 – Geochemical data:Comprehensive geochemical measurements of samples analyzed in this study. The dataset includes major and trace element concentrations, Fe speciation and Mo-Fe isotopic compositions. The data provide the basis for evaluating geochemical processes and paleoenvironmental interpretations discussed in the manuscript. Supplementary Table 2 – Parameters of all models:Input and output parameters used in geochemical and statistical models. These parameters support reproducibility of the modeling procedures and allow further exploration of sensitivity tests and scenario analysis.
