O cinturão cupro-aurifero de Carajas, Brasil

Abstract: A presente tese trata da geologia, caracteriza9lio de mim\rios e geocronologia U-Pb SHRIMP dos depositos cupro-auriferos de Igarape Bahia, Breves e Cento e Dezoito, e ainda da geologia e metalogenese do deposito de Au-Pd-Pt de Serra Pelada. Os resultados mostram que ocorreram no Cinturao Cupro-Aurifero de Carajas ao menos dais eventos metalogeneticos distintos, urn no Neoarqueano ( -2,57 Ga) representado pelo deposito de Fe-oxido Cu-Au-(U-ETR) de Igarape Bahia e outro no Paleoproterozoico (-1,88 Ga) tipificado… Show more

“…The tectonic evolution of the Carajás Basin is ascribed to at least three main hypothesis, including the formation during a dextral transtension, subsequently tectonically inverted to positive flower structures by sinistral transpression ), during continental rifting related to mantle-plume activity (Tallarico 2003) and in a volcanic arc setting related to subduction processes (Meirelles 1986;Dardenne et al 1988;Meirelles and Dardenne 1991;Teixeira 1994;Lobato et al 2005;Teixeira et al 2010).…”
