In-situ laser ablation and multicollector–inductively coupled plasma–mass spectrometry were combined to analyse for sulfur isotopes in sulfide minerals that occur in the 2.7-billion-year-old black shale of Serra Sul, Carajas mineral province, Bra

Magnetite bands in sericitic phyllite of the Batatal Formation mark the transition to the overlying 2.65-Ga Itabira iron formation, or Caue Itabirite, in the Quadrilatero Ferrifero of Minas Gerais, Brazil. The magnetite bands have low (non-crustal) T

Uranium–Pb dating of zircon from a metavolcanic layer within the Itabira iron formation, or Caue Itabirite, Quadrilatero Ferrifero of Minas Gerais, Brazil, indicates that its deposition occurred at 2.65 Ga, i.e., considerably earlier than proposed

Talc mineralisation occurs as hematite–talc schist between soft hematite ore and dolomitic itabirite at Gongo Soco, Quadrilatero Ferrifero of Minas Gerais, Brazil. The hematite–talc schist and soft hematite have a prominent tectonic foliation of
