Late Quaternary tectonics controlled by fault reactivation. Insights from a local transpressional system in the intermontane Lerma valley, cordillera oriental, NW Argentina

Abstract To improve the knowledge about the Quaternary tectonic landforms, their potential level of activity, and the associated inherent seismic hazards in the Cordillera Oriental of northwestern Argentina we analyzed the Lomas de Carabajal area along the western border of the Lerma valley. In this region, Pliocene to Pleistocene synorogenic conglomerates are folded and faulted with a NNW-SSE trend, locally showing high angle dipping, and an en-echelon arrangement characterized by wavelengths of
