Abstract The thick‐skinned fold‐and‐thrust belt on the eastern flank of Andean Plateau in northwestern Argentina (NWA) is a zone active contractional deformation characterized by fault‐bounded mountain ranges with no systematic spatiotemporal pattern tectonic activity. In contrast, thin‐skinned Subandean northern and southern Bolivia primarily in‐sequence (i.e., west to east) fault progression, narrow Quaternary focused at front orogenic wedge. To better understand how recent accommodated...
Abstract This study shows the neotectonic deformation occurred in southern piedmont of Cumbres Calchaquíes, Amaicha and Tafí valleys. Neotectonic manifests itself through faults, folds diversions drainage channels. The valley is bounded to north by del Valle fault south Los Cardones fault. Calchaquíes ride over Sierra de Aconquija Carapunco faults. also has a synestral component, responsible for generating an imbricated system contractional fractures. In region many earthquakes ≥ 3 4...
