The Upper Jurassic of the Moroccan margin, particularly in the Agadir Essaouira basin, and
specifically in its western part towards the Atlantic Ocean, is characterized by geological diversity. The
reef association of Cap Ghir in the western High Atlas is mainly composed of bioconstructions such as
colonies of stromatoporoids, which are abundant during the initial reef formation. These colonies exhibit
massive or globular forms similar to those of corals. Other bioclastic elements such as bivalves and
gastropods are also found, which contribute to reef construction and are often cemented by algal or
microbial micrite. The area is characterized by an abundance of branches and masses, generally exhibiting
Framestone and Bindstone textures, indicating a turbulent environment.
