“…Subduction-related magmatism in the Sierras Pampeanas segment ceased about ~465 Ma (Cristofolini et al, 2012;Ducea et al, 2015;Morosini et al, 2017;Otamendi et al, 2017). At this time, the Famatinian orogen began its intense construction, southward of 28° south latitude, so the arc and backarc were internally structured and differentially uplifted during the collision of the Laurentian-derived Cuyania/Precordillera microcontinent (Thomas and Astini, 1996;Benedetto, 2004;Otamendi et al, 2020) against the western margin of Gondwana (Astini and Davila, 2004;Ramos, 2004;Otamendi et al, 2009Otamendi et al, , 2017Ducea et al, 2010Ducea et al, , 2015Ramos et al, 2010;Cristofolini et al, 2014). This continent-arc collision conditioned the different orientations of the fault trends during the Mid Ordovician-Early Devonian times (von Gosen et al, 2002;Astini and Dávila, 2004).…”
