Preserved carbon isotope compositions in 3.7 billion year old detrital organic matter from the Isua Supracrustal Belt
Abstract Graphite found along contiguous horizons in the metamorphosed detrital sediments from the ≥ 3.7 Ga Isua Supracrustal Belt in Southwest Greenland may represent the oldest remains of life on Earth. Here, we examine the carbon isotope compositions of graphite occurring in situ as inclusions in...
