Those features are contemporaneous to the Tonian Taphrogenesis that has been recognized all over the Rodinia supercontinent as the first extensional phase that led to the fission of this supercontinent elsewhere. Archean and Paleoproterozoic sedimentary and volcanosedimentary covers, some of which associated to anorogenic plutonism, have a remarkable representation in Brazil. The Amazonas and São Francisco syn-Brasiliano cratons host the largest exposures of pre-Ordovician weakly deformed units in the Capítulo I
