Verdecchia, Sebastián ; Casquet, César ; Baldo, Edgardo G. ; Pankhurst, R.J. ; Rapela, Carlos W. ; Fanning, C.M. ; Galindo Francisco, Mª del Carmen | Geological Society of London. | 2011The Early Palaeozoic stratigraphy and tectonic history of the Eastern Sierras Pampeanas of central Argentina are complicated by metamorphism and deformation resulting from the Pampean (545–510 Ma) and Famatinian (490–440 Ma) orogenies. We report[...]![]()
