Full textThe lithostratigraphic and structural analysis of the Beni Bou Ifrour’s massif show distinct areas: - a northern unit (Ouiksan’s area) characterized by carbonate sedimentation in the upper Jurassic, and detritic deposits with volcano-sedimentary material in the lower Cretaceous (Berriasian). This area is characterized by many tectonic stages; - a southern unit “the J. Harcha’s area” characterized by Liassic carbonate-sedimentation at the bottom and terminated by a calcarenitic Miocene formation. This area is characterized by a single tectonic stage. The northern part of the massif is intruded by a granodiorite which intersects the schistosty. The granodiorite is chemically similar to surrounding volcanic rocks. This study permits to connect structurally the massif Beni Bou Ifrour with the Temsamane’s massif (external Rif) ; lithostratigraphycally this massif is situated like an intermediate element between the Rif belt (Temsamane’s massif) and fore land (the Gareb belt)

Full textThe Betic-Rif Cordillera, located in the western part of the Mediterranean, results from the convergence of the European and African plates and related subduction processes. It is therefore an exceptional site to study the processes induced by subduction dynamics. This thesis focuses on the study of the internal domain of the Rif chain. Two key areas have been selected (Ceuta and Cabo Negro) where high pressure-low temperature crustal rocks (HP-LT) (present only in Ceuta) but also low pressure-high temperature rocks (LP-HT) and ultrabasic rocks outcrop. Their tectonic significance, placement mode and ages are still heavily debated subjects. A multidisciplinary approach was developed to carry out this work, with a detailed structural and petrographic study, as well as U/Th/Pb dating on zircon, monazite and xenotime and 40Ar/39Ar on white mica. The results obtained show that: (i) at circa 29 Ma a medium pressure-high temperature metamorphism (MP-HT) affects the lower Sebtides and Ghomarides. This phase is simultaneous with a thickening of the crust and the placement of diorite sill having a geochemical signature of calc-alkaline to high-K magmatic arc. This phase is contemporaneous to the HP-LT metamorphism observed in the crustal units of the upper Sebtides (ii) at circa 21 Ma an extension phase contributes to the final exhumation of these rocks. This event is associated with a metamorphic episode developed at the boundary between Amphibolite and Greenschist facies conditions, at 400-550°C and 1-3 kbar. The quasi-contemporary emplacement of metamorphic units with radically different thermal gradients is characteristic of “paired metamorphic belts”. In this case we propose the following model: at 29 Ma, during Alpine subduction, the units of the Ghomarides and Lower Sebtides are located within the upper plate of the subduction system where the MP-HT metamorphism develops. In parallel, the HP-LT metamorphism occurs within the lower plate constituted by the upper Sebtides. Dehydration of the lower plate induces calc-alkaline magmatism in the upper plate. At 21 Ma, the slab rollback produces an extension phase creating the opening of the Alboran basin and the exhumation of the HP-LT units

Full textLocated at the extreme tip of the western Mediterranean, the Betic-Rif orogenic system is built through a complex alpine orogenic history involving processes of subduction related to convergence between Africa and Eurasia since the Cretaceous. A remarkable discovery during the last four decades of geological investigations, has been the remains of a variscan event in the internal zones of the belt. These results underline the presence of two superimposed orogenic systems, the internal zones of the belt thus remain a privileged area to study the importance of the structural and the metamorphic heritage in the partial or total reactivation by the most recent events. This work is located in the Beni Bousera sector, where crustal and mantle rocks that form the innermost units of the chain are exposed. Based on structural and petrological analyses, U-Th-Pb dating on monazite and 40Ar-39Ar dating on micas and amphiboles. The history of the Betic-Rif belt can be summarized as it follows: 1) a HP-HT event affects the base of the internal domain at around 281 ± 3 Ma. These new petrological and geochronological data obtained in the internal Rif, are correlated with the Betics, the Kabyle, the Edough massif of Algeria, the Mauritanian, and the Appalachian belts, attesting a convergent domain during the late Carboniferous – early Permian. All of these orogenic segments are part of the North African Variscides built at the north-western margin of Gondwana in response to convergence between the later and Laurentia. 2) at around 29-26 Ma, a Barrovian to Abukuma metamorphic event affects the Sebtides (the innermost units of the chain) and interpreted as the evolution of the upper plate of a subduction zone. This alpine event is typically characterized by a prograde metamorphic path marked by heating affecting the base of the Sebtides between 26 to 22 Ma, such conditions reflect thinning and heating of the crust related to the asthenosphere upwelling due to slab roll-back. This event marks the beginning of a major extensive event. 3) In the Miocene around 22-20 Ma, the internal zones are affected by an E-W extension contemporary to the opening of the Alboran Basin in a back-arc context, and the intrusion of granitic dykes into the peridotites and crustal metamorphic units, the exhumation of the Sebtides was complete at this time. 4) From early to middle Miocène, the Betic-Rif belt acquired its arcuate geometry (the Gibraltar Arc) during the collision between the Internal and the external zones, attested by de NE-SW to E-W shortening phases across the arc. 5) more lately prior to Pliocene, the Gibraltar arc was subjected to contractional possess related to a N-S shortening phase, which drastically altered its geometry
