Abstract

The Saïss basin has long been the subject of numerous geological studies owing to its paleogeographic location in the western part of the South Rifian—Corridor that linked the Mediterranean to the Atlantic during the Tortonian–early Messinian (Cirac in Mémoires de l’Institut de Géologie du bassin d’Aquitaine 21:1–287, 1987 [3]; Wernli in Notes Et Mémoires du Service géologique du Maroc 331:1–270, 1988 [9]; Zizi in Triassic–Jurassic extension and Alpine inversion in the northern Morocco, pp 87–101, 1996 [10]). The Miocene-Pliocene sedimentary series deposited in Sais basin have recorded the different biostratigraphic events, environmental, tectonic and eustatic factors that preceded the Messinian salinity crisis. The current data on the closure of the North and South Rifian corridors are conflicting and it cannot explain the thick evaporitic series accumulated during the Messinian salinity crisis (Capella et al. in Earth Sci. Rev. S0012–8252:30217–30219, 2018 [2]; Flecker et al. Earth Sci. Rev. 150:365–392, 2015 [4]). Does exist any other communication links between the Atlantic and the Mediterranean Sea? To resolve this issue, it must be established an accurate framework to the studied basin, delineated the vegetation evolution during the Tortonian–Messinian. Therefore, it may redound to understanding all environmental, climatic and eustatic events that led to the Messinian salinity crisis, also to typify communications evolution between Atlantic and Mediterranean gateways across the southern Rifian corridor during the Upper Miocene.
