Resumen:
The Quaternary deformation in Cafayate valley has been documented, near to Quebrada La Yesera, mainly as sinsedymentary structures in Cafayate-Santa María paleolake. (13,830 years BP. until 4800 years BP). In this work it has been described the deformation that affect the fluvio-aluvial Quaternary deposits as well as Cafayate-Santa María paleolake deposits in the piedmont of Sierra de León Muerto. This range is bounded by the E-dipping Castillo Fault. The structures that affect the Quaternary deposits are reverse faults that has been interpreted as splay faults (footwall shortcut) of the Castillo Fault that generated thrust folds. Our new data documents sustained Holocene shortening in this structurally complex region.
