Graphite preserved in ancient mountain belts linked to supercontinent assembly

This study investigates the history of graphitic carbon in two ancient North American mountain belts related to Nuna supercontinent assembly. Using rhenium–osmium and uranium–lead dating,

the research reveals that biogenic graphite was hydrothermally remobilized in shear zones during late orogenesis, indicating periodic carbon cycling over 200 million years. Access through
