Resumen

Preliminary paleomagnetic data obtained in marls of the Avellaneda Formation (La Providencia Group) of Ediacarian age outcropping in the Río de la Plata craton (RPC) are presented. Sampling was carried out in quarry and in a bore-core. Standard stepwise demagnetization showed a directional consistency among both sets of samples yielding a preliminary paleomagnetic pole located at 0.8° N, 308.4° E, (A95: 5.7°, n: 68) for the Avellaneda Formation. This indicates very high latitudes for the craton and suggests that the most accepted Ediacarian apparent polar wander path (APWP) for the 600-500 Ma period for RPC must be reconsidered.
