Abstract

Field relationship, U-Pb zircon geochronology, whole rock trace element, and Sr and Nd isotope geochemistry will be combined to constrain the geological evolution of the Paleoproterozoic Rio Itapicuru greenstone belt, São Francisco Craton, Bahia. Special emphasis will be given to the precollisional history of the greenstone belt. As a working hypothesis, we will test a model of continental rifting, ocean openning, intra-oceanic arc and final continent-continent collision to form part of a Paleoproteozoic supercontinent. (AU)
