“…Other Betic gateways (e.g. Zagra, Dehesa de Guadix, North Betic straits; Figure ) are also inferred to have shallowed and closed during the late Tortonian due to tectonic uplift (Betzler et al., ; Corbí et al., ; Hüsing et al., ; Krijgsman et al., ; Martín, Braga, Aguirre, & Puga‐Bernabéu, ; Martín et al., ; Meijninger & Vissers, ). This resulted in the deposition of Tortonian evaporites in the Granada, Lorca and Fortuna basins (Figure ; Cambeses & Scarrow, ; García‐Veigas et al., ; Krijgsman et al., ).…”

New age constraints on the western Betic intramontane basins: A late Tortonian closure of the Guadalhorce Corridor?

Several gateways connected the Mediterranean with the Atlantic during the late Miocene but the timing of closure and therefore their role prior to and during the Messinian Salinity Crisis (5.97-5.33 Ma) is still under debate. The timing of closure of the Guadalhorce Corridor is especially disputed as the common lack of marine microfossils hampers precise age determination. Here we present new biostratigraphic age constraints on the sediments of the Ronda, Antequera and Arcos regions, which formed the northern part of the Guadalhorce Corridor. The general presence of Globorotalia menardii 4 in the youngest deep-marine sediments of all three regions indicates a late Tortonian age, older than 7.51 Ma. We conclude that the Guadalhorce Corridor closed during the late Tortonian, well before the onset of the Messinian Salinity Crisis and that the late Tortonian tectonic uplift of the eastern Betics extended into the western Betics.

“…The ~SW‐NE extension of the central Betics (Figure b), which is still ongoing today (Mancilla et al, ; Palano, González, & Fernández, ), occurred while the region was uplifted above sea‐level from the late Tortonian onwards (Corbí et al, ; Rodríguez‐Fernández & Sanz de Galdeano, ). Convergence‐induced shortening created only localized antiforms that disconnected peripheral basins from the main gateways, such as the Ronda Basin in the western Betics (Jiménez‐Bonilla et al, ).…”

Mantle resistance against Gibraltar slab dragging as a key cause of the Messinian Salinity Crisis

The Messinian Salinity Crisis (5.97–5.33 Ma) was caused by the closure of the Atlantic‐Mediterranean gateways that cut through the Gibraltar orogenic system. The geodynamic drivers underlying gateway closure and re‐opening are still debated. Here, we interrogate the gateway successions to find the imprints of surface deformation, infer the timing and nature of associated geodynamic drivers, and test such inferences against numerical simulations of slab dynamics. We find that since the latest Miocene, a tectonic framework was established in the gateway region dominated simultaneously by (a) relative plate convergence, (b) slab tearing under the eastern Betic Cordillera and (c) mantle resistance against north‐northeastward dragging of the Gibraltar slab by the African plate's absolute motion. We propose that mantle‐resisted slab dragging and slab tearing operated in concert closing the gateways that caused the Messinian Salinity Crisis, whereas sinking of heavy oceanic lithosphere located between buoyant continental plates re‐opened the Strait of Gibraltar at 5.33 Ma.

“…Braga et al (1990) suggested instead that restriction began on the eastern side of the basin in the late Tortonian, spreading to the southern and western margins which uplifted around the Tortonian-Messinian boundary, gradually isolating and desiccating the basin and filling it with continental deposits. The restriction of the Granada Basin has recently been more precisely dated using biostratigraphy by Corbí et al (2012) demonstrating that a short phase of evaporite precipitation occurred between 7.37 to 7.24 Ma, followed by a less well constrained phase of continental sedimentation. This confirms the conclusion of earlier studies that the Granada Basin was not a conduit for Mediterranean-Atlantic exchange for any part of the Messinian.…”

Marine gateways play a critical role in the exchange of water, heat, salt and nutrients between oceans and seas. As a result, changes in gateway geometry can significantly alter both the pattern of global ocean circulation and associated heat transport and climate, as well as having a profound impact on local environmental conditions. Mediterranean-Atlantic marine corridors that pre-date the modern Gibraltar Strait, closed during the Late Miocene and are now exposed on land in northern Morocco and southern Spain. The restriction and closure of these Miocene connections resulted in extreme salinity fluctuations in the Mediterranean, leading to the precipitation of thick evaporites. This event is known as the Messinian Salinity Crisis (MSC). The evolution and closure of the Mediterranean-Atlantic gateways are a critical control on the MSC, but at present the location, geometry and age of these gateways is still highly controversial, as is the impact of changing Mediterranean outflow on Northern Hemisphere circulation. Here, we present a comprehensive overview of the evolution of the Late Miocene gateways and the nature of Mediterranean-Atlantic exchange as deduced from published studies focussed both on the sediments preserved within the fossil corridors and inferences that can be derived from data in the adjacent basins. We also consider the possible impact of evolving exchange on both the Mediterranean and global climate and highlight the main enduring challenges for reconstructing past Mediterranean-Atlantic exchange.
