Structural sections of the Sierras Australes in the Buenos Aires province: Stratigraphic repetition through reverse faults?
The Sierras Australes or Sierras de la Ventana are in the southern part of Buenos Aires province, between 37o-39o S and 61o-63o W and constitute a curved fold and thrust belt with a general northwest strike. They are formed by Precambrian to Permian rocks. The oldest and more intensely deformed rock...
