Fig. 8 Conceptual structural cross-section through studied area based on Zizi (1996) and own field observations (scale 1:1). Subsurface thicknesses are extrapolated from sections of nearby wells published in Saadi et al. (1980) and Sani et al. (2006). Subsurface positions of not-exposed tectonic elements after Tilloy (1952), Zizi (1996), and Zouhri et al. (2002)

Fig. 2 Geological map of the studied area from Dar bel Hamri to El Kansera resulting from a review of my master thesis (1977), and highlighting sections sampled.The location of the subsurface Sidi Fili fault and Nappe Prérifaine front are extrapolated from Tilloy (1952) and the postulated extension of the Kenitra-Sidi Slimane fault is from Zouhri et al. (2002)
