  • Paleomagnetism of the Notch Peak contact

    Since magnetite composed a very small fraction (∼10 −4 by mass as estimated in section 3.2) of the unmetamorphosed limestones, and since pyrite was abundant in these rocks, as indicated by ubiquitous hematite pseudomorphs after pyrite in the unmetamorphosed sites (12HB) [Gillett et al., 1982], this assumption seems reasonable.

  • Pyrite formation from FeS and H2S is mediated

    Pyrite is the most abundant iron−sulfur mineral in sediments. Over geological times, its burial controlled oxygen levels in the atmosphere and sulfate concentrations in seawater. However, the mechanism of pyrite formation in sediments is still being debated. We show that lithotrophic microorganisms can mediate the transformation of FeS and H2S to FeS2 at ambient temperature if metabolically ...
