Tertiary tectonics of the sub-Andean region of the North Patagonian Andes, southern central Andes of Argentina (41–42°30′S)

The North Patagonian orogenic front and related foreland evolution during the Miocene, analyzed from synorogenic sedimentation and U/Pb dating (∼42°S)

“…This unit comprises clastic and pyroclastic deposits with subordinated carbonates (Cazau, 1972(Cazau, , 1980Spalletti, 1981;Cazau et al, 1989;Mancini and Serna, 1989;Bechis, 2004;Giacosa et al, 2005;Paredes et al, 2009). The first descriptions of this unit identified eight different sections (Feruglio, 1941;1947;Petersen and González Bonorino, 1947;Volkhaimer, 1964: Gonzalez Bonorino andGonzález Bonorino, 1978), although this subdivision was later simplified into three members after the work of Mancini and Serna (1988).…”

Restos de pingüinos del Cenozoico medio de la cordillera Patagónica.

“…The paleobiogeographic affinities of the fauna in the El Foyel Group are important as they should provide further confirmation -or not-of the currently accepted Pacific-connected basin configuration. Such a configuration is closely linked to the history of Cenozoic uplifting of the Andes as a result of tectonic processes occurring along the western margin of the South American plate at that time Ramos, 2008a, 2008b;Giacosa and Heredia, 2004;Giacosa et al, 2005). The distribution of the taxa contained in these rocks is inconclusive as to an Atlantic or Pacific origin of the basin.…”

Taphonomy and dispersion of bones scavenged by New World vultures and caracaras in Northwestern Patagonia: implications for the formation of archaeological sites

“…1) includes high elevations of the North Patagonian Andes (2000-2300 masl) and low mountains (1300-1800 masl) of the Patagonian Pre-cordillera (Giacosa and Marquez 1999;Giacosa et al 2005). The climate is cold with strong westerly winds and a significant west-east rainfall gradient due to the Pacific anticyclone and the topographic barrier of the Andean Cordillera, which generates drier conditions to the east .…”
