“…Platt et al Late Burdigalian to Langhian sediments onlap the thrust, demonstrating that the contact became inactive at the end of the early Miocene. In the central Betics, Serravallian sediments are involved in the backthrusting, indicating that activity continued on the contact until the middle Miocene (Martín-Algarra et al 1988). The tip of the Alborán wedge, where the backthrust meets the underlying forethrust, probably reaches the early Miocene ground surface beneath the Granada Basin; from that point west, the IEZB is a west-northwest-directed forethrust.…”

The Betic-Rif arc is one of the smallest and tightest orogenic arcs on Earth, and together with its extensional hinterland, the Alborán Domain, it formed between two colliding continents. The region provides examples of a range of tectonic processes that are not predictable from the rules of rigid-plate tectonics. The Alborán Domain reveals two stages of subduction and accretion, with different thermal histories and mechanisms of exhumation. The external Betic-Rif thrust belt illustrates four processes that create an arcuate orogen and a strongly divergent pattern of slip vectors: (a) the interaction between the westward moving Alborán Domain and the converging African and Iberian margins, (b) divergence in relative motion due to extension within the Alborán Domain, (c) slip partitioning onto strike-slip faults within the arc, and (d) vertical-axis rotations resulting from oblique convergence on the limbs of the arc.

“…In the Western Mediterranean, the intra-Burdigalian tectonic events are related to distinct rifting along the Iberian margin, an episode of widespread volcanism, the (near) end of rifting in the Sardinia Rift (Sowerbutts and Underhill, 1998) and the Valencia Trough (Roca, 2001), and collision of the internal and external zones of the Betics (Martin-Algarra et al, 1988). The anticlockwise rotation of the Corsica^Sardinia block slowed down and ultimately came to a halt at 181 7 Ma ago (Edel et al, 2001) or slightly later (161 5 Ma ago, Chamot-Rooke et al, 1999).…”

“…It originated after deposition of a sequence of Aquitanian? to Serravallian age, which sequence includes several tectonosedimentary breaks from the top of the Burdigalian Alamillos Formation to the top of the La Peza Formation (Martin Suarez et a l , 1993; see also Martin-Algarra et al, 1988;Sanz de Galdeano & Vera, 1992). As one of the larger intramontane basins of the Betic Cordillera, the basin took shape in the early Tortonian.…”

“…A similar tectonostratigraphic relationship may have existed for the deep-water marls of the Fuente Formation. The collision of Alboran and Iberia is reflected by the intra-Burdigalian tectonic phase which ended rifting and caused the destruction of the Subbetic continental slope (Martin-Algarra et al, 1988;Sanz de Galdeano & Vera, 1992). The post-collision breccias, conglomerates and sandstones of the late/middle Burdigalian Espejos Formation accumulated unconformably in a deep-water basin.…”

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 ...
