Ore types comprise quartz veins and disseminations hosted in the mylonitized metaconglomerate (Fortuna Formation, Aguapeí Group) and amphibole-biotite-chlorite mylonite. The native gold is associated with pyrite, pyrrhotite, chalcopyrite, native silver, galena, hematite, magnetite and martite. The aqueous-carbonic (type 1) and aqueous inclusions (type 2) in the quartz veins suggest that ore genesis is related to metamorphic fluids percolation during the late regional shearing. The ore remobilization was promoted by meteoric fluids, which are preserved as aqueous inclusions (type 3) in quartz veins.</p><p> </p>}, number={1}, journal={Pesquisas em Geociências}, author={BARBOZA, ELZIO DA SILVA and PULZ, GÊNOVA MARIA and RONCHI, LUIZ HENRIQUE and JELINEK, ANDRÉA RITTER and PINHO, FRANCISCO EGÍDIO and QUADROS, ÁLVARO PIZZATO}, year={2001}, month={jun.}, pages={65–80} }
