A quartz-pyroxene rock interpreted as a banded iron formation (BIF) from the island of Akilia, southwest Greenland, contains13C-depleted graphite that has been claimed as evidence for the oldest (>3850 million years ago) life on Earth. Field relationships on Akilia document multiple intense deformation events that have resulted in parallel transposition of Early Archean rocks and significant boudinage, the tails of which commonly form the banding in the quartz-pyroxene rock. Geochemical data… Expand
Does a Heavy Fe-Isotope Composition of Akilia Quartz-Amphibole-Pyroxene Rocks Necessitate a BIF Origin?
New Fe isotope data is presented from all lithologic variants in the qap gneiss on Akilia, including layers of undisputed ultramafic igneous origin, arguing that Fe isotopes must therefore be treated with considerable caution when used to infer BIF for part or all of theqap protolith. Expand

Clues from Fe Isotope Variations on the Origin of Early Archean BIFs from Greenland
The observed enrichments are compatible with the transport, oxidation, and subsequent precipitation of ferrous iron emanating from hydrothermal vents and thus suggest that the original rocks were banded iron formations (BIFs), which support a sedimentary origin for the Akilia banded rocks, which represent one of the oldest known occurrences of water-laid deposits on Earth.

Chemical and isotopic evidence for widespread Eoarchean metasedimentary enclaves in southern West Greenland

Fluid-deposited graphite and its geobiological implications in early Archean gneiss from Akilia, Greenland.
Petrographic and Raman spectroscopy data from this gneiss reveal the occurrence of graphitic material with the structure of nano-crystalline to crystalline graphite in trails and clusters of CO₂, CH₄ and H₁O bearing fluid inclusions, consistent with an abiologic, fluid deposited origin during a poly-metamorphic history.

Metamorphic alteration, mineral paragenesis and geochemical re-equilibration of early Archean quartz–amphibole–pyroxene gneiss from Akilia, Southwest Greenland
Quartz–amphibole–pyroxene gneiss from the island of Akilia, Southwest Greenland has been claimed to contain the earliest traces of life on Earth in the form of biogenic carbonaceous matterExpand
Reassessing the evidence for the earliest traces of life
It is shown that graphite occurs abundantly in secondary carbonate veins in the ISB that are formed at depth in the crust by injection of hot fluids reacting with older crustal rocks (metasomatism); these metasomatic rocks, which clearly lack biological relevance, were earlier thought to be of sedimentary origin.

Carbon isotope composition of graphite and carbonate minerals from 3.8-AE metamorphosed sediments, Isukasia, Greenland
Abstract Graphite comprises about 2% of some of the 3.8-AE metamorphosed sedimentary rocks of Isukasia, west Greenland. δ13CPDB of carbon in this graphite ranges from −16.0 to −9.3‰. For thoseExpand

Recognition of > or = 3850 Ma water-lain sediments in West Greenland and their significance for the early Archaean Earth.
Rocks from the island of Akilia provide proof that by approximately 3850 Ma there was a hydrosphere, supporting the chemical sedimentation of BIF, and that not all water was stored in hydrous minerals and that conditions satisfying the stability of liquid water imply surface temperatures were similar to present.

Origin of life from apatite dating?
It is concluded that, about 1,500 Myr ago, these apatites in Akilia island experienced a metamorphic event of about 600 °C (estimated by the closure temperature of the U-Pb system), which is consistent with measurements of 1,600-1,700 Myr for Rb-Sr mineral isochrons on biotites and 1,670 Myr for K-Ar muscovite from Amitsog gneiss in the region.
