dc.descriptionThe Luís Alves, Serra Negra and ltatins complexes are Arehean to early Proterozoic metamorphic units in the Brazilian States of Santa Catarina, Paraná and São Paulo, south of the 24°S parallel. This paper summarizes their geological evolution based on petrographic, chemical, and mainly geochronological data. The three complexes consist of metamorphic rocks of the granulite facies, dominantly: norites, enderbites. charnoenderbites, ultramafites of granulite facies, kinzigites, quartzites, biotite-hornblende gneisses, meta-quartz diorites, metadiorites, metagabbros, serpentinites and talcites. Petrographic and chemical data support an igneous origin for most of these rocks. The radiometric age determinations made bythe Rb-Sr and the K-Ar methods on different materiais gave results related, for the most part, to the Pre-Jequié (about 3,100 m.y.), Jequié (2,600 ± 200 m.y.) and Transamazônico (2,000 ± 200 m.y.) events. Geochronological data suggest that the three complexes were formed predominantly by crustal accretion-differentiation processes.en-US
