Apport de l'imagerie radar SAR-ERS à l'analyse de la géométrie de la déformation récente dans les monts des Béni Snassen (Maroc nord-oriental). Contribution of the imagery radar SAR-ERS to the analysis of the geometry of the recent deformation in the Beni Snassen mounts (North-eastern Morocco).
Résumé : Les techniques de traitement permettent, dès à présent, une exploitation opérationnelle des images satellitaires radar SAR-ERS dans un contexte cartographique. L'utilisation de cette imagerie au Maroc nord-oriental a permis d'extraire la géométrie de la déformation. Trois réseaux de failles de direction NW-SE, NE-SW et ENE-WSW apparaissent au travers des principales unités morphologiques. La disposition et le caractère récent des jeux de ces failles sont confirmés sur le terrain. Ceci a permis d'établir un modèle d'évolution structurale des monts des Béni Snassen dans le cadre de l'évolution des chaînes maghrébines en contexte de collision entre les plaques lithosphériques Afrique - Europe.
Image processing techniques already allow the operational use of radar satellite SAR-ERS imagery for cartography. Its use in North-eastern Morocco made it possible to extract the geometry of the deformation. Three directions of major faults oriented NW-SE, NE-SW and ENE-WSW appear to the breadth of the main morphological units. The arrangement and the recent character of the sets of these faults are confirmed on the field. This was used to establish a model of structural evolution of the Beni Snassen mounts within the framework of the evolution of the maghrebin chains in context of collision between the African - European lithospheric plates.
