Abstract The Horto-Baratinha (HBD) iron ore deposit is located at the eastern border of Sao Francisco Craton, comprising BIF-hosted high-grade bodies (>60 wt.% Fe) associated with polydeformed quartz-mica-schists, amphibole-schist of Statherian maximum deposition age, enclosed by Statherian granitoids of the Borrachudos Suite and Neoarchean gneiss. All the sequence is crosscut by undeformed dikes and sills of pegmatitic bodies probably formed during Late Ediacaran-Cambrian. The metasedimentary s...

Mineralogical and whole rock geochemical analyses for 60 elements on 31 samples of hard ferruginous crust (canga) provide insights into the evolution of the lateritic profile developed on itabirite. Canga can form in two environments: in situ canga that typically caps itabirite and transported canga that covers country rock. Both have similar mineralogical and chemical compositions. Detrital haematite and rare quartz inherited from the itabirite and iron ore comprise the matrix of canga, cemente...

The Precambrian of South America contains world-class iron formation (IF) occurrences of Archean, Paleo-, and Neoproterozoic age preserved in its different cratonic fragments and surrounding collisional belts developed during their amalgamation along a protracted Neoproterozoic to Early Paleozoic event known as the Brasiliano-Pan-African collage that formed the southwest part of the Gondwana supercontinent. In the domain of South America located west of the Transbrasiliano Lineament, most Archea...

Abstract The Picarrao and Liberdade deposits contain high-grade iron orebodies (>65% Fe) hosted in the Guanhaes Group itabirite, that are associated with pegmatite veins and bodies. Fluid inclusion studies in quartz veins associated with the high-grade orebodies show that medium to high salinities (25–28 wt% NaCl eq.) and temperatures (275–375 °C) fluids are associated with the silica leaching that led to the iron enrichment. Mineral chemistry studies by LA-ICP-MS in the iron oxides demonstrate ...

Turmalina is an important orogenic gold deposit located in the NW region of the Quadrilatero Ferrifero. The deposit is hosted in an Archean greenstone belt composed of ortho-amphibolites and pelites with interleaved tuffs metamorphosed under amphibolite facies conditions and intruded by a granite stock. The orebodies are controlled by WNW-ESE-trending shear zones, associated with hydrothermal alteration. Three deformation events are recognized in the Turmalina gold deposit: D1 and D2 are the res...

A sequencia supracrustal Guanhaes, portadora de formacoes ferriferas bandadas (BIFs), ocorre como fatias tectonicas superpostas ao embasamento de terrenos granito-gnaissicos do tipo TTG de idade Arqueana, desenvolvidas no limite entre o periodo Proterozoico e o Paleozoico, durante a colagem Brasiliana. A idade maxima de deposicao da sucessao e de ~2,18 Ga e foi determinada por datacao de zircoes detriticos em quartzitos. Alem de quartzitos, a sucessao e composta por xistos, BIFs, gnaisses e anfi...

The Minas Supergroup banded iron formations (BIFs) of the Brazilian Quadrilatero Ferrifero (QF) mineral province experienced multiple deformational events synchronous with hypogene mineralization, which resulted in the metamorphism of BIFs to itabirites and their upgrade to high-grade iron ore. Here, we present rare earth element and yttrium (REE+Y) compositions together with iron isotope ratios of itabirites and their host iron orebodies from 10 iron deposits to constrain environmental conditio...

Abstract Hydrothermal fluids related to the development of the Aracuai Orogen during the Brasiliano Cycle have affected Paleoproterozoic banded iron formation-bearing sequences along the eastern border of the Sao Francisco Craton. Controversy surround the origin of specularite in high-grade schistose iron ore-bodies in the Serpentina Range (“Serpentina-type” ore) versus specularite-rich, S-free Au-PGE quartz veins (“Jacutinga-type”) that occur at the eastern border of the Quadrilatero Ferrifero ...
