Detailed structural and geological mapping was carried out in the Lomas de Carabajal region. In this area the Plio- Pleistocene Piquete Formation appears intensely folded and faulted, being unconformably overlain by the Upper Pleistocene alluvial conglomerates of the La Viña Formation. These conglomerates are folded and show growth strata geometries near their limiting faults. The N-S striking folds along the Lomas de Carabajal are en-echelon structures and have short wavelengths (
