摘要：
A comparative study of the Middle Liassic series in the south western part of the Middle Atlas system leads to the definition of three new formations callec. Fellat 1, 2 and 3. They mainly involve gravity-flow deposits related to the breakup of the regional carbonate platform in a subsiding area, the Selloum Basin. The creation of this basin provides evidence for a rifting stage during the Carixian-Domerian interval, inducing the separation of the Sellourn unit with respect to the Middle Atlasic trough and its possible connection with the High Atlasic sedimentary domain.
