“…The distribution of the clay minerals in the middle Danian to middle Eocene (64 to 42 Ma) R ıo Chico Group succession in the Golfo San Jorge Basin, to the south of Salta Basin, was studied by Raigemborn et al (2009Raigemborn et al ( , 2014. These authors identified a variable abundance of smectite and kaolin minerals throughout the succession and correlated this with hyper-thermal events of the Early Palaeogene Global Warming.…”

“…In addition, beds bearing reptilian fossils were recorded in the sections Cañadón Hondo and Cañadón Vaca (Simpson, 1937). Thus, stratigraphic position, facies and fossil content support a probable equivalence of the Cerro Verde sections with the lowermost section of the Sarmiento Formation (Cañadón Vaca Member after Bellosi & Krause, 2014). Andreis, 1977;Pol et al, 2012).…”

“…8.2 Del total de datos analizados, es posible concluir que las illitas presentes en las pelitas de la formación Vaca Muerta no presentan un origen común, tal como refleja la variación de su IC. Una importante proporción de ellas pueden asociarse a un origen detrítico (muestras del campo de las rocas ígneas y metamórficas y la anquizona, IC entre 0 y 0,4) mientras que otras son consideradas autigénicas (campo de la diagénesis, IC entre 0,4 y 1), estas últimas se asocian a un origen a partir de la transformación de esmectita durante la diagénesis, la cual resulta un argilomineral muy abundante en rocas volcánicas y volcaniclásticas como producto de la alteración del vidrio volcánico (Raigemborn et al, 2014). Los altos estándares de aluminio registrados pueden ser explicados gracias al estudio de proveniencia del material detrítico, principalmente aportado de las rocas ígneas corticales ácidas a intermedias, que conforman el basamento de la región de estudio (Spalletti et al, 2015).…”
