Abstract: Paleomagnetic parameters measured in 4 outcrops of the Tufos de Condeixa are presented. The directional signatures allow the admission of the Reversed Polarity Criptchron C1n-1 in the Condeixa-a-Velha outcrop. It was possible to discuss the magnetic properties, origin of the magnetic grains and paleoclimatic variation relationships. The downward of the initial magnetization and magnetic susceplibility values in the Condeixa-a-Velha outcrop coincide with the Cln-1 (504-493 Ka) occurrence and may represent a paleoclimatic variation. The Tufos de Condeixa were formed during the Ionian-Tarentian(?).
