Supplementary Data 1–6 and Source Data for "Metal-driven anaerobic oxidation of methane and the Sturtian deglaciation"

This dataset supports the study titled “Metal-driven anaerobic oxidation of methane and the Sturtian deglaciation”, which provide geochemical evidence for a methane-related biogeochemical pathway driving Fe-bearing mineral transformation via methanogenesis and metal-driven anaerobic methane oxidation (AOM), mediated by methanogens and anaerobic methane-oxidizing archaea (ANME) in ferruginous settings.Supplementary Data 1–6 comprise geochemical datasets including major and trace element concentrations, and Fe (δ⁵⁶Fe) and Ni (δ⁶⁰Ni) isotope compositions of hematite and magnetite, as well as bulk-rock and in situ carbon (δ¹³C) isotope data from Mn-rich carbonates from five well-preserved Sturtian-aged IFs in South China.The Source Data file contains the raw numerical values underlying all scatter plots and box plots presented in the main text and supplementary figures.
