the magnesite veins are located in the beni bousera massif (internal rif, morocco), especially in tafidest region about 103 km sw of the tetouan city. they are hosted by perridotite and serpentinite formations.  the aim of this study is to clarify the origin of this type of orre genesis. geochimical study of magnesite ore reveals that is a cryptocrystalline magnesite, formed by the co2-rich hyd...

The timing and process of exhumation the subcontinental peridotites Gibraltar Arc (Ronda, Beni Bousera) have been discussed extensively over last decades. In this work, we contribute to debate through first mapping, structural petrological analyses, SHRIMP U-Th-Pb dating high-grade marbles that crop out around Bousera antiform Alpujarrides-Sebtides units northern Rif (Morocco). These marbles, h...

Located at the westernmost tip of Mediterranean, Gibraltar Arc is a segment Alpine belt that exhibits peridotite massifs associated with high-grade crustal metamorphic units. The timing and mechanisms exhumation these crust–mantle associations are still debated in Rif Morocco as well Betic Cordilleras Spain. A structural, petrographic, geochronological study ( 40 Ar– 39 Ar method) performed Ben...
