Stratigraphy and sedimentology of the ordovician units of the central section of the mojotoro range, eastern cordillera, northwest Argentina

This work shows the sedimentological study of the rocks that form the San Bernardo, 20 de Febrero and Vélez hills that emerge on the eastern border of the city of Salta (Argentina) and constitute the central sector of the Mojotoro range. In the succession analyzed, the Pedrera, Floresta, Áspero, San...
