Sedimentary provenance in the southern sector of the São Francisco Basin, SE Brazil

Brazilian Journal of Geology
: We present new Sm-Nd, U-Pb and Hf isotope geochronological data for the siliciclastic rocks in the southern sector of the São Francisco Basin. An abrupt change in the Sm-Nd data is observed from the Carrancas Formation’s oligomitic conglomerates (TDM ...
