Full textThe mantle deformation processes that control the thinning and break-up of continentallithosphere remain poorly understood. Our knowledge is restricted to either lithospheric scalethermo-mechanical models —that use experimentally derived flow laws—, geophysicalimaging and/or rare xenoliths from active continental rifts, such as the East African Rift System.The originality of this work relies on the study of the two largest outcrops of diamond faciessubcontinental lithospheric mantle in the world: the Beni Bousera and Ronda peridotite massifsin N Morocco and S Spain, respectively. The structures and petrologic and metamorphic zoningpreserved in these massifs —implying a polybaric and polythermal evolution— provide aunique opportunity to investigate the thermo-mechanical evolution of thick subcontinentallithospheric mantle in extensional settings.In this thesis we studied the deformation mechanisms in both peridotites andpyroxenites to constrain the modes of exhumation of subcontinental lithospheric mantle fromgarnet-, to spinel-, and finally, to plagioclase lherzolite facies conditions. We combined fieldmapping of tectono-metamorphic domains and structural mapping of ductile structures,microstructural analysis, crystal preferred orientations (CPO) measurements and conventionalthermobarometric calculations and thermodynamic modeling (Perple_X) to unravel the pressureand temperature conditions of deformation. We showed that exhumation from garnet- to spinellherzolite facies conditions was accommodated by fast shearing —in thermal disequilibrium—along a lithospheric scale transtensional shear zone. In this context, the petrological zoning andthe large temperature gradient (ca. 100ºC/km) preserved in the Beni Bousera massif representthe mechanical juxtaposition of progressively deeper and hotter lithospheric levels at depths ofca. 60 km in the latest Oligocene (ca. 25 Ma). Final exhumation from spinel- to plagioclasefacies lherzolite and emplacement into the crust is best recorded in the Ronda massif where itoccurred by inversion and lithospheric scale folding of the highly attenuated continentallithosphere in a back-arc region, probably in relation with southward slab rollback andsubsequent collision with the palaeo-Maghrebien passive margin in the early Miocene (21-23Ma)

The Beni Bousera ultramafic massif is a tectonically emplaced body of upper mantle material that is exposed over 72 km2 in the Betic-Rif-Tell orogenic belt of northern Morocco. The massif is composed primarily of spinel lherzolite, although meter-scale domains of harzburgite, dunite, and veins and layers of pyroxenite are relatively common. A combined field and laboratory-based investigation of Beni Bousera has yielded a new dataset comprised of whole rock and mineral chemistry data that is used to suggest the massif is more heterogeneous than previously interpreted, and that "secondary" peridotites and dunites were formed by different petrogenic processes than the remainder of the massif. Trends in the CaO-MgO-Al 203-SiO 2 system and trace element patterns suggest partial melting of the peridotite played a significant role in the evolution of the massif, as has been previously suggested for other orogenic peridotites. Heterogeneous zones - regions throughout the massif with diverse groups of peridotites and pyroxenites - are believed to be relict melt transport channels. Peridotites and pyroxenites found in these zones show evidence of interaction with a relatively depleted melt (high Cr, low Al and Ti in mineral phases), and textures that suggest the secondary precipitation of neoblastic pyroxenes along matrix olivine grain boundaries. Rare earth element concentrations of clinopyroxene from two peridotite groups suggest equilibration in the garnet stability field, and temperatures calculated from dysprosium concentrations are usually higher than those determined from two-pyroxene thermometry. Linear major element patterns versus MgO and whole rock REE compositions of Beni Bousera dunites suggest that they cannot have formed via partial melting alone. The data collected here also suggest that the massif has experienced several mantle P/T conditions, and continuously equilibrated during exhumation and emplacement into the crust. A comparison with the geometry of the melt transport domain at Ronda, another Mediterranean peridotite body, suggests that although Beni Bousera and Ronda may be related in age of exhumation, melt may have been transported via different pathways in the two massifs.
