In the Moroccan Meseta Devonian series are deposited conformably on the Silurian formations. During the Devonian, the area underwent a change in the type of deposition. The Saharian influence, which characterised the Lower Palaeozoic, stopped and was replaced, especially in the western Meseta, by the development of a carbonated platform with reefs. This platform extended from the present-day Atlantic coast to the Oulmes area eastwards. To the south, it developed in the northern Rehamna and the western Jebilet. In contrast, the depositional regime in the eastern Meseta was characterised by a turbiditic series, composed, from the west to the east of detrital deposits with wacks, microbreccias and microconglomerates, flyschs, and reefal limestones of the Early and Middle Devonian, in the form of olistolites in the Visean of the Zekkara and Jerrada areas, similar to those of the western Meseta. These different characters enabled to differentiate four main zones in the Moroccan Meseta during the Devonian: - the Sehoul Block to the north (an emerged area at this time), on the southern border of which reefal formations existed and extended until the Imouzzer inlier south of Fes; - a first carbonated platform in the western Meseta; - a second platform located in the southeastern part, which would corresponded to the Oranian Meseta; - a deep NE-SW trending trough with pelagic and detrital deposits between the two plat-forms.
