Antiquity and evolutionary status of bacterial sulfate reduction: Sulfur isotope evidence

Abstract

The presently available sedimentary sulfur isotope record for the Precambrian seems to allow the following conclusions: (1) In the Early Archaean, sedimentary δ3 4 patterns attributable to bacteriogenic sulfate reduction are generally absent. In particular, the δ3 4 spread observed in the Isua banded iron formation (3.7×109 yr) is extremely narrow and… (More)
