“…Consequently, the preserved remnants (generally as small and scattered outcrops) do not allow of the detailed reconstruction of their geometric features and sedimentary fills, or for that matter their precise typological classification. In the Betic Internal Zone the scattered, allochthonous syn-rift strata of the Alozaina-Tolox region (northwest of Malaga; unconformably overlying the Malaguide nappes) and the La Viñuela-Majiaza region (northeast of Malaga; unconformably overlying the Alpujarride nappes) are particularly representative for this kind of deformed basin (DurandDelga et al, 1993;Sanz de Galdeano et al, 1993). Examples are the pre-Late Miocene fills of the Granada, Guadix-Baza, Sorbas-Tabernas and Ugijar Basins ( includes the compressional Proto-Guadalquivir foreland basin, to which the Moratalla Basin belongs, and, partly, the North African Flysch Trough.…”

The destruction of the flysch trough was accompanied by the tectonogravitational emplacement of the Neonumidian Formation and succeeded by post-collisional backthrusting of the flysch complex at the end of the Burdigalian (Guerrera et al, 1993).The Late Oligocene and Early Miocene Campo de Gibraltar and Maghrebian flysch units are correlative with a lithologically diverse group of marine, partially olistostromic and turbiditic formations (Sanz de Galdeano & Vera, 1992;Sanz de Galdeano et al, 1993), which formed an areally irregular sedimentary 'cover' on thrusted basement rocks of the Betic Internal Zone (Balanyá & García-Dueñas, 1987;González-Lodeiro et al, 1996). The unconformable superposition of these strata on top of …”

The geological configuration of the present-day Mediterranean is characterized by a complex and extensive system of both interconnected and fragmented fold-and thrust belts that is associated with back-arc basins (e.g. Carminati et al., 1998;Rosenbaum & Lister, 2004). Their tectonic structure and setting are varied, and the compressional origin and growth of the different belts and the formation of the adjoining extensional basins also varies considerably in age. The different fold-andthrusts belts did not evolve during one single, uninterrupted cycle of Alpine orogenesis, but are the ultimate outcome of a prolonged, polyphase process of intermittent plate-tectonic interaction between the African-Arabian and Eurasian plates. This resulted in the creation and ultimate disappearance of two major oceanic basins, the Palaeotethys (mainly Palaeozoic) and the Neotethys (late Palaeozoic-Mesozoic). As in the preceding Jurassic and Cretaceous times, the motions of Africa-Arabia relative to Eurasia during the Tertiary were an important control on the geological evolution of the Alpine Tethys (late Mesozoic-Tertiary). Various kinematic frameworks for palaeotectonic and palaeogeographic reconstructions have been proposed for the region (e.g. Dewey et al., 1989;Rosenbaum et al., 2002). These were mostly based on analysis of rotation parameters (poles of rotation, rotation angles), which allowed to constrain past relative velocities between Africa and Eurasia. In addition, analysis of North Atlantic magnetic lineations helped to constrain the movement of Africa and Europe relative to North America. The consensus view is that during the Late Cretaceous Africa converged towards Europe in a S-N directed rotational mode. This was contemporaneous with spreading of the Azores part of the North Atlantic, the coeval opening of the Gulf of Biscay like a sphenochasm and the resulting anti-clockwise rotation of Iberia with respect to Eurasia. Sinistral motion occurred after an active plate boundary subject to left-lateral strike-slip faulting had been established at the northern margin of the Iberian block. Consequently, Iberia behaved like a promontory AbstractThis paper integrates the sequence stratigraphic and tectonic data related to the Neogene geodynamic and palaeogeographic development of the African-Iberian plate boundary zone between Spain and Morocco. Though the dating of individual tectonostratigraphic sequences and their delimiting sequence boundaries varies in accuracy and precision, their apparent correlation strongly suggests contemporaneous development of the Betic and Rif basins. This may likely be attributed to regional changes of the overall compressional intra-plate stress field. This, in turn, was governed by coeval plate-kinematic changes related to the ongoing collisional convergence of Africa and Iberia. The Neogene succession is characterised by brief tectonic pulses that governed the sequence stratigraphic development of the Betic-Rif basins (NBR phases). It broadly correlates with the coeval sequences in the ...

The Tamezzakht succession (Maastrichtianmiddle Burdigalian), situated at the fringe between the Internal and the External zones, displays contrasting lithologies with abrupt facies changes, discontinuities, and/or coarse-grained calciturbidite in between. These criteria allow the definition of seven main lithostratigraphic formations.Depositional environments (oxygenation levels, trophic conditions, omission histories, among others) and/or transgressive/regressive trends are inferred from integrated sedimentologic data including facies change, cyclicity pattern and the textural composition of the turbidite facies tracts. Special emphasis is given to the ichnological features.Taking into account the extended time-range, the position between the internal zones and the external ones, as well as the clear differentiation into several contrasting sedimentary formations, the Tamezzakht succession is expected to provide useful stratigraphic data for the regional correlations.
