“…Geochronological studies of felsic and intermediate volcanic, pyroclastic and intrusive rocks helped to constrain the magmatic activity recorded by the Mitu Group in southern Peru (Erlich, Fallon, et al, 2018;Kontak et al, 1984Kontak et al, , 1990Reitsma, 2012;Spikings et al, 2016). These data together with detrital zircon age data indicated to Reitsma (2012), Spikings et al (2016) and Carlotto et al (2023) that deposition of the Mitu Group commenced at least in southern Peru only in the middle Triassic, between 245 and 240 Ma (Anisian). Spikings et al (2016) concluded that "there is currently no evidence to support Permian or even Lower Triassic rocks in the Mitu Group".…”

“…Informally named Ene Group: Ene, Noi, Shinai and Lower Nia formations (Carrillo et al, 2021;Erlich, Fallon, et al, 2018;Erlich, Hermoza, et al, 2018;Grader et al, 2008;Sempere et al, 2002). Pucarà Formation: Rosas et already in the Triassic (Carlotto et al, 2023). In more local studies, the Mitu Group has been divided into the Pisac and Pachatusan formations (Carlotto, 1998) or the Lower Mitu and Upper Mitu Group, respectively (Cenki et al, 2000).…”
