“…Nevertheless, this cannot be possible because it strongly contradicts the paleogeographic configuration of southwestern Gondwana during the Late Triassic (Hervé et al, 2008;Suárez et al, 2019;Vizán et al, 2017). Then, a tectonic event could have affected the batholith and produce the tilting of the block, during the Jurassic extensional period (Figari, 2005) and, or, during a compressional stage, during the Late Cretaceous or later, related to the Andean Orogeny (Bilmes et al, 2013(Bilmes et al, , 2014Savignano et al, 2016;Zaffarana et al, 2018b). The main fractures in the Gastre area show a NW-SE direction and could have been originated during the formation of the Cañadón Asfalto Basin (Figari, 2005), where they acted as normal faults (part of half grabens), probably developed aided by the previous Paleozoic structures (Renda et al, 2019).…”
