Resumen

The La Paya granite is located in the Sierra de Cachi (Salta, Argentina) and belongs to the Eastern Cordillera of the Andean belt. New structural and cartographic data combined with the study of the magnetic fabric of the granite indicate that: 1) the pluton is a sheeted body, about 400 metres thick, that outlines an antiformal fold, 2) its roof is coincident with a folded ductile shear zone. Moreover, field and microstructural observations point to a syn-kinematic emplacement of the pluton linked to an extensional shear zone that was folded by a subsequent compressional event.
