Lithology description: Arenaceous to carbonaceous shales, or fine clays, often markedly to finely laminated, with frequent plants in much greater variety than in either of the higher horizons.
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).
