2021/1/28These have a minimum age of ~3,700 Ma in Isua (Moorbath et al., 1973; Nutman et al., 1997a) and could be as old as ~3,850 Ma on Akilia Island (Nutman et al., 1997b; Mojzsis and Harrison, 2000). Unfortunately these rocks have been subjected to intense meta-morphism, so any fossilized morphological remains of Earth's earliest biosphere, if any ever existed at that time, have been

[PDF] Evidence for biogenic graphite in early Archaean

The Archaean rocks of Isua, West Greenland, contain graphite, but its origins are debated. Geochemical and microscopic analyses suggest that the graphite was formed from biologically formed carbon that was deposited at least 3.7 billion years ago.
