. The evolution of the South American gondwanic border during the Ediacaran-Lower Cambrian led to different hypotheses about its consolidation and evolution. The classical interpretation, derived from former authors, describes an area that includes the central and northwest region of Argentina and part of Bolivia as an autochthonous region within Gondwana (e.g. Windhausen, 1931; Keidel, 1943; Turner, 1960; Borrello, 1972; Turner and Mon, 1979; Jezek et al., 1985). The geological events related to the sedimentation, metamorphism,plutonism, and orogenesis comprises the ‘Pampean Cycle’ that is recorded in the Pampean Orogen. These were developed on an intra- and peri-Gondwanan position in which the ‘Puncoviscana Formation s.l.’ and its stratigraphic equivalents were deposited (Acen˜olaza and Toselli, 1976; Acen˜olaza and Acen˜ olaza, 2005, 2007).s.l.’ and its stratigraphic equivalents were deposited (Acen˜olaza and Toselli, 1976; Acen˜olaza and Acen˜ olaza, 2005, 2007).
