The Nahuel Niyeu Formation is a low-grade metamorphic unit consisting of alternating beds of metasedimentary rocks derived from siliciclastic protholits, with minor intercalation of metaigneous rocks. It is part of the early Paleozoic basement of the eastern North Patagonian Massif. In this contribution we present U-Pb detrital zircon ages from three metagreywackes of the Aguada Cecilio area.
