Lithostratigraphic analysis and characterization of the upper miocene deformation of the Beni Bou Ifroure massif (Jbel Harcha Unit) eastern Rif Morocco

In the eastern Rif unit of Jbel Harcha which is part Beni Bou Ifroure massif, latter belongs to chain was formed during Alpine orogeny. Lithostratigraphic analysis geological map and field investigations shows that this constituted by carbonate facies limestone attributed lower middle Jurassic. At level upper Jurassic Cretaceous we observe metamorphic terms presented schists. The structural examination allows distinguish two types deformation first one penetrative materialized a metamorphism formations whose direction planes schistosity varies between N125 N140. This type linked NE-SW shortening, Tortonian set open normal faults N040 N045. second generally characterized brittle structures dextral strike-slip N120 N140 intersect ancient accidents. episode N-S NW-SE shortening responsible for N070 thrusting rocks in study area.
