Résumé
In the northeastern border of the Duero Bassin two erosiona/ surfaces formed on mesozoic materials are distinguished. The oldest one, actually limited to isolated summits, is probably of middle-Miocene age. The youngest one is linked to the colmation surface of the Duero Bassin ("Páramos" limestones) and therefore of Turolian-Pliocene age. Tectonic deformations with a NW-SE strike affecting this surface in the southeastern border of the Cantabrian Chain are deduced
