The Flyshs georoad runs from the western limit of the Jbel Moussa SIBE to southwest of Tangier presents different types of Flyshs. It located in the Rif (northern part of Morocco), which is characterized by metric to decametric thickness formations, generally representing alternating of sandstone beds and shale. A part of this area belongs to the Intercontinental Biosphere Reserve of the Mediterranean (RBIM). The Flyshs georoad hold a geodiversity that should be conserved since this type of rocks and climate of the study area favored the development of ecosystems. For this reason an inventory and quantitative assessment have been performed using the method of Brilha. As a result, twelve geosites have been selected, which represent the different units of the Flyshs and geological facies. Among the twelve geosites, ten of them have a scientific value (VS) over than 3.5. All geosites have a high educational and touristic value, due to their easy access and because they correspond to the Flyshs that are most representative in the Maghreb basin. However, the risk of degradation (DR) remains moderate. Geoconservation measures should be taken to protect the selected geosites. The Flyshs geotroad with the twelve geosites could help to ensure sustainable development and develop the geoeducation and geotourism in the study area.
