Abstract
From recent data, the author strives to justify division of the Würm in three parts: Eowürm (75 000 B P. -55 000 B P.), Mesowürm (55 000 B. P. -27 000 B.P.), , Néowürm (27 000 B.P.-10 300 B P.). He tries to caracteris some great natural domains utilizing particularly mousterian and leptolithic settlements maps, « front pioneer » succeeding positions between gulf of Gascogne and Volga. Finally tight relation is suggested between « industrial complexs » sequence and generalized paleoclimatic curve.
