Resumo

THE JUSCELÂNDIA SEQUENCE AMPHIBOLITES, GOIÁS: GEO-TECTONIC IMPLICATIONS.Trace and rare earth element composition of the Proterozoic amphibolites from the lower unit of the Juscelândia volcano-sedimentary sequence, State of Goiás, Brazil, suggests a non-subductipn, tholeiitic original nature for these rocks, probably of back-arc type tectonic setting.A more detailled reconstruction of the geotectonic evolution of the sequence, requires a reappraisal of its larger geological environment, particularly involving the critical area of the Barro Alto complex.
