Lithology and environment
| Primary lithology: | white "shale" | ||
| Lithology description: "The Potrerillos Formation is composed of thick, coarse conglomerates at its base and by thinner conglomerates, sandstones, bentonites, mudstones, and carbonaceous shales in the middle and upper part of the unit. It represents a mix of braided-river channels, floodplain deposits, and high-sinuosity meandering channels." Martins-Neto et al., 2007 Insects come from the upper part of the formation | |||
| Environment: | lacustrine delta plain | Tectonic setting: | rift |
| Geology comments: The Cuyo Basin may be characterised as a passive rift basin produced as a result of generalised extension induced by crustal thinning and collapse of the Upper Palaeozoic (Gondwana) orogen (Llambías and Sato, 1990, 1995; Spalletti, 1999). It can be defined as a half graben that shows strong asymmetric structural and depositional features, as well as intrabasinal highs or transference zones that delimit different depocentres (Kokogián et al., 1988, 1993; Ramos and Kay, 1991; López Gamundí, 1994; Spalletti, 1999, 2001). | |||
