Stratigraphy of the el imperial formation (Penssylvanian-cisuralian) in the atuel canyon, san rafael basin

The El Imperial Formation is the classic sedimentary unit of the upper Palaeozoic (Pennsylvanian-Cisuralian) of the San Rafael Basin. It is one of the best known basins in the central-western of Argentina. The studied unit is not in complete agreement with the rules of the Código Argentino de Estrat...
