Neotectonic transpressive zones in the precordillera sur, central andes of Argentina: A structural and geophysical investigation

On the flat-slab segment of the Central Andes of Argentina, the southern portion (31°30' - 33° SL) of the Precordillera is characterized by a singular Late Cenozoic tectonic style related to the tectonic inversion of paleotectonic anisotropics. Different scale, neotectonic NW trending deformati...
