FAIXA DO PERAU: UMA UNIDADE FACIOLÓGICA E TECTONO-METAMÓRFICA DO GRUPO AÇUNGUI

Resumo

The purpose of this work is to demonstrate that only if we integrate the sin-sedimentary tectonic, paleo-environmental and subordinated magmatic agents and processes, it will be possible to reconstruct the entire evolution of a litho-stratigraphical column of Precambrian sediments of the Acungui Group, in Southern Brazil, and to include in it the metallogenetic episodes that originated several mineralizations in Pb, Ag, Zn, Ba and Cu (Perau Mine), Ba (Água Clara and Tigre Mines) and Pb (Seabra Mine). A geological cartography is included to give evidence of the evolution presented.
