Abstract
Highlights
- High precision carbon isotope study of graphites from the North China Craton.
- Stratabound graphite ores show δ13C values of ca. â25.5â° corresponding to biogenic origin.
- Graphite in veins and melt pockets show 13C enrichment with heaviest δ13C up to â15.8â°.
- Evidence for microbial life flourishing in the Paleoproterozoic oceans.
- Implications for fluid mixing with CO2 from sub-lithospheric sources.
