Stratigraphy comments: These localities are Puchuzum (Calingasta Valley), whose faunal assemblage is assigned to the Huayquerian SALMA (late Tortonian–Messinian; see Deschamps et al. 2013, for further details in bio- and chronostratigraphic equivalences), |
Lithology and environment
Primary lithology: | gray,red or brown sandy siltstone |
Includes fossils? | Y |
Lithology description: the bony remains recorded in this locality, which come from the middle of the exposed section, were assigned to the latest Miocene. This mid-section is characterized by brown-reddish to greyish psammo-pelitic deposits, reddish silty to silty-sandy beds, with some carbonaceous and con- glomeratic levels, and with cut and fill structures. Three man- tiform interbeddings of bentonitic clay, 3 to 10 m thick, are distinguished by their yellowish coloration. These bentonitic packages clearly correspond to sedimentary events that orig- inated in lakes, evidenced by the recorded fossils: bivalves, gastropods, insects, and fish | |
Environment: | wet floodplain |
Geology comments: The general palaeoenvironment of the mid-section of
Puchuzum is interpreted as a fluvial system with great devel-opment of flood plains and rivers, more or less channelled and strongly sinuous. The lacustrine interbeddings correspond to increasing and decreasing events of the lacustrine basin, in-fluenced by tectonic and hydrologic activity. A similar situa-tion has been interpreted for the Las Flores Formation in the Iglesia Basin/ |
