The Couro de Onça intrusive suite (COIS) is late tectonic relative to major deformational events, and the Serra do Meio suite (SMS) postdates this event, being interpreted as anorogenic type, deformed during the Brasiliano cycle (0.65–0.52 Ga). The COIS encompasses alkali-feldspar granites, syenogranites, monzogranites, with dykes of similar composition and age (2.15795 Ma). They are metaluminous rocks of alkaline affinity, whose evolution was probably controlled by mineral fractionation processes involving mainly plagioclase, amphibole, and Fe–Ti oxide. The SMS, whose probable age is 2.01 Ga, is composed of metaluminous and peralkaline granites, with associated quartz syenites, with Ti-aegirine transformed during the Brasiliano deformation to riebeckite titanite aenigmatite. The temperatures of two stages of metamorphic transformation, overprinted during the Brasiliano event, are estimated at about 550 and 400–450°C. Both magmatic suites are derived from enriched mantle sources. The metaluminous and peralkaline trends observed in the SMS, characterized by high concentrations of HFS and RE elements controlled mainly by F-activity, reflect the evolution of different primary magmas produced by successive melting of the same mantle sources, in an anorogenic setting.Submitted by Ana Valéria de Jesus Moura (anavaleria_131@hotmail.com) on 2012-01-25T12:38:56Z No. of bitstreams: 1 S0301926800000814-main.pdf: 2921220 bytes, checksum: 0e8fcaccfe604dd99b8008aabeeed8f8 (MD5)Made available in DSpace on 2012-01-25T12:38:56Z (GMT).
