Elemental and stable isotopes geochemistry of Paleoproterozoic dolomites from Fecho do Funil Formation, Quadrilátero Ferrífero - Brazil

The δ13CVPDB (+6.0 to +7.2‰) and δ18OVPDB (−10.9 to −10.4‰) values in our samples display a narrow range which are identical to those shown by successions, characterized by positive carbon excursions, deposited during the Lomagundi event. We infer that the elevated carbon isotope values of the Fecho do Funil dolomites likely reflect primary carbon isotope compositions.
