≥3700 Ma pre-metamorphic dolomite formed by microbial mediation in the Isua supracrustal belt (W.Greenland): Simple evidence for early life?

Chemical (meta)sedimentary rocks in the amphibolite facies ≥3700Ma Isua supracrustal belt (W. Greenland) are mostly strongly deformed, so there is only a small chance of the survival of features such as stromatolites or microfossils that would be direct
