Resumen:
Rock-magnetic experiments, petrographic studies and X-ray diffraction analyses were applied onremagnetized carbonates from the Upper Cambrian La Flecha Formation (Quebrada La Angostura,Precordillera de La Rioja, Argentina) carrying a pre-tectonic Permian secondary magnetization with the aimto extend the knowledge of the widespread Sanrafaelic overprint which affected most of the early Cambrianto mid-Ordovician units of the Argentine Precordillera and the San Rafael Block.
