Carbon isotope fluctuations in precambrian carbonate sequences of several localities in Brazil
Carbon isotope fluctuations in Precambrian sedimentary carbonates between 2.8 Ga and 0.60 Ga in Brazil are examined in this study. The carbonate facies of the BIF of the 2.8 Ga-old Carajás Formation, state of Pará in northern Brazil, has rather homogeneous d13C (-5 o/ooPDB), compatible with carbonat...
