Thallium isotope insights into Mn Oxides as precursor to Ediacaran Mn Carbonate Ore

The Supplementary Material presents data in Tables 1–3, including pyrite framboid diameters, bulk geochemical compositions of samples from the studied Mn deposits (Tl isotopic compositions, major element, trace element, rare earth elements, and Fe speciation), and Re-Os elemental abundances with isotopic ratios.
