Lithology and environment
| Primary lithology: | "siliciclastic" |
| Includes fossils? | Y |
| Lithology description: This unit is sedimentologically very similar to the underlying formation (Ensenada Formation), but with less consolidated sediments (Tonni et al. 1999b), and the predominance of smectites could be linked to greater water content at the time of sedimentation (Nabel et al. 1993). | |
| Environment: | terrestrial indet. |
| Geology comments: Sedimentological analyses of the Buenos Aires Formation show that, like the Ensenada Formation, is composed of alternating loess (deposited under cold arid conditions) and paleosoils (indicators of warmer and more humid climatic-environmental conditions), but with sediments less consolidated than in the underlying unit (Ensenada Formation) (Orgeira et al. 1998; Tonni et al. 1999b; Nabel et al. 2000). In this sense, the Bonaerian seems to represent a predominantly cold arid or semiarid phase (Cione & Tonni 2001), with brief interspersed warmer and more humid periods (Tonni & Cione 1994). | |
