English: The north-eastern boundary of the Canigou massif, which is broadly defined by the Lentilla valley between the Palomeres (Palomère) col and Baillestavy, and where the massif towers over the Aspres massif to the east, has been accentuated by Neogene normal fault movement along the Aspres fault (even thought that fault acted earlier as a thrust fault, pushing the Aspres westwards, during the Eocene Pyrenees mountain-building period).
