... decades. In this work, we contribute to this debate through the first mapping, structural and petrological analyses, and SHRIMP U-Th-Pb dating of high-grade marbles that crop out around the Beni Bousera antiform of the Alpujarrides-Sebtides units of northern Rif (Morocco). These marbles, here termed...

... belt is archetypal of this behavior. A synthesis of the tectonometamorphic evolution of the Internal Zones, also based on recent findings by our group in the framework of the Orogen Project (Alboran domain, including the Alpujárride-Sebtide and Nevado-Filábride complexes) shows the relations in space...

...Emmanuelle Homonnay; Jean-Marc Lardeaux; Michel Corsini; Asmae El Bakili; Delphine Bosch; Olivier Bruguier; Mohamed Ouazzani-Touhami Abstract We document the occurrence of micro-diorite magmatic sills, with magmatic enclaves, in the Ceuta Peninsula within metapelites from the Lower Sebtides units...

... that constitute most of the backbone of the Internal domain of the Rif orogen in North Morocco. The Internal Rif is composed by the continental deep units of the Sebtides, exhumed at the end of the Alpine cycle, overlained by the Variscan Ghomarides. Both units are trust above the meta-carbonates of the Dorsale...

...Mohamed Bouybaouene; Andre Michard; Bruno Goffe Abstract Kyanite-bearing basic granulites occur in the kinzigite envelope of the Beni Bousera peridotite massif (main Sebtide nappe, Rif, Morocco). Their major and trace elements chemistry support an origin from an Al-rich tholeiitic melt. The primary...

...) that of Alpujarride-Sebtide rocks to which they were formerly ascribed. Magmatic and metamorphic rocks very similar to those studied characterize the basements of some Kabylia and Calabria-Peloritani units. Therefore, the source area is a currently lost continental-crust realm of Calabria-Peloritani-Kabylia type...

These data allow a paleogeographic restoration, which implies the presence of a microcontinent...

The Internal domain of the Rif comprises, from the top to the bottom, the non-metamorphic Mesozoic carbonate margin of the Alboran Domain or the so-called ‘Dorsale Calcaire’, the low-grade to non-metamorphic sedimentary Paleozoic formations, the so-called ‘Ghomarides’ and the Sebtides unit...
