Resumen

This work deals with the structure of the Lower Cambrian batholith of Tastil (Salta, NW Argentina) and its influence on the development of younger Andean structures. Anisotropy of magnetic susceptibility data reveal a laccolithic intrusion spreading laterally from a central root zone. The N-S elongation of the batholith reflects the westward propagation of Andean thrusts through the sheeted domains of the intrusion, the root zone acting as a buttress that restricted the propagation of the Andean structures.
