摘要

•Evaluation of the detrital zircon from the Ribeira Belt using statistical metrics.•Multidimensional scaling shows similarity between the Apiaí and São Roque terranes.•Multidimensional scaling shows dissimilarity between the Embu and adjoining terranes.•We show a great similarity between the Embu Terrane and SW Laurentia.•The statistical metrics support an allochthonous affinity of the Embu Terrane.
