Formação Rosário do Sul

Abstract

One of the most controverted aspects in the stratigraphy of tge Gondwana of the Parana Basin has always been the limit between the Permian and the Triassic rocks. The greatest problem in Rio Grande do Sul is concerned to the identification of the beds situated between the Estrada Nova and the Botucatu Formations. These beds have been interpreted as different units and consequentely receiving different names.
