..., coupled with geochronological methods and P – T estimates, reveal polyphase contractional deformation and metamorphism during the Famatinian Orogeny over a long period of time. Peaks of metamorphic monazite and zircon ages are recorded at c. 500 Ma, between 484 and 465 Ma and at c. 440 Ma. Between 484...

... with an additional peak at 1.3–0.9 Ga and they can be correlated with ‘Grenvillian’ age, and the Brasiliano, Pampean, and Famatinian orogenies. The zircon data reveal main transport from the nearby Ordovician Famatinian arc and related rocks. The Silurian sandstone units are more comparable with Cambrian units...

... Cordillera of Peru, and the Amotapes Massif. Detrital sediments of the forearc are marked by a major gap in Early Cretaceous–Jurassic ages and the minor presence of Ordovician (Famatinian orogeny) and Carboniferous–Permian (340–285 Ma) ages. The age spectrum is not compatible with sediment input from...

... Ma highly peraluminous granites in the Eastern Sierras Pampeanas. After brief quiescence, a second major episode, the Famatinian orogeny, started with subduction ca. 490 Ma, forming a wide continental arc and ensialic backarc basin. This heralded the approach of Laurentia to Gondwana, during which...
