Abstract

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.

古代山脉带中保存的石墨与超大陆组装有关

这项研究调查了与努纳超大陆组装有关的两个北美古代山脉带中石墨碳的历史。研究利用铼-锇和铀-铅测年法揭示了生物成因石墨在成岩晚期剪切带中的水热再移动，表明在2亿年的时间里存在周期性的碳循环。
