Measurements of palaeomagnetic inclination in sediments from the French Pays Basque, representing three of the major Pleistocene biostratigraphic subdivisions previously identified, confirm normal polarity in all cases. Taken together with the palaeobotanical, stratigraphic and geomorphological evidence they suggest that the Moulignan, Senixian and Ilbarritzian stages lie within the early part of the present Brunhes normal polarity epoch and probably correlate with some unknown part of the “Cromerian Complex”. The Bidartian is thought to lie within a normal polarity event during the Matuyama epoch and to correlate with part of the Tiglian ‘A’ sub‐stage of the Netherlands.
