Palaeomagnetic evidence has suggested that the Lower Palaeozoic carbonatic platform of the Argentine
Precordillera was affected by a regional event of remagnetization occurred during the Late Palaeozoic,
possibly related to the Sanrafaelic Orogeny. Though detailed magnetic mineralogy research in these
carbonates could provide clues to the geologic processes involved in this phenomenon, systematic study is
still necessary. The present work presents the preliminary results on the magnetic properties of five Middle
Cambrian to Early Ordovician carbonatic formations (limestones to dolomites) exposed in the Eastern
Precordillera which carry a post-folding magnetization assigned to a Permian age and associated to the
Sanrafaelic remagnetizing event.
