In the middle Ouerrha region, the study of the upper Jurassic mudstones blocks which emerge in a complexe tectonic position either side of Moulay Bouchta village, has permitted to establish a detailed stratigraphy and to subdivide the serie of the Malm-Berriasian in two formations :- in the base, the mudstones of Msila ;- in the top, a serie more marly which we calle marly-mudstones of El-Bouïed.The vertical and horizontal variations of the facies which represent these formations leads us to define seven members and to make a spatial cutting of the sector in two facies zones : the zone of east Moulay Bouchta and the zone of West Moulay Bouchta.The bio and lithostratigraphic analyses in the same time of the Prerif blocks show that the latera...
