“…Contemporaneously, Messinian valleys and canyons identified on seismic lines and in drill cores, were infilled and buried (Druckman et al, 1995;Buchbinder and Zilberman, 1997;Guennoc et al, 2000). The amplitude of the sea level rise that led to the reestablishment of marine conditions in the Mediterranean is attested by the geometries of the deltaic progradational-aggradational wedges above the MES (Lofi et al, 2003;Duvail et al, 2005;Gorini et al, 2005, Kertznus andKneller, 2009;Hawie et al, 2013b. In addition, clinoform geometries are good paleodepth indicators (Urgeles et al, 2011;Rabineau et al, 2014) that provide an estimated sea level rise of 800-1000 m (above the last Messinian lowstand paleoshore position, Leroux et al, 2014).…”

International audienceThrough several examples we show that following sea-level fall and marginal erosion during the Messinian salinity crisis (MSC), clastic inputs into the eastern and western Mediterranean Sea are not distributed evenly in space and time but are mainly limited to the lower section of the Messinian salinity crisis depositional megasequence. Significant similarities around the basin allow us to propose a Mediterranean Messinian salinity crisis depositional episode that can be divided into two seismic megasequences: the Messinian lower megasequence (MLM) and the Messinian upper megasequence (MUM). Their distinctive seismic facies correspond to systems tracts deposited during three main stages that represent a complete sea level cycle. (1) A falling stage systems tract including mass transport deposits and forced regressive clinoforms deposited in in the early part of the falling stage, and related to the increasing rate of relative sea level fall. This stage is characterized by a marked shift in the depocenter towards the deep basins. (2) An early lowstand characterized by massive clastic inputs from major Messinian rivers (the Rhone, Nile, and Antalya Gulf rivers) or smaller river systems (offshore south Lebanon). These clastics were deposited in an oversaturated basin, as evidenced by the interfingering chaotic and transparent seismic facies of the Messinian lower megasequence (MLM). (3) A late lowstand, starting with rapid deposition of massive halite, with no detrital inputs into the deep basin. The upper part of the evaporites clearly onlaps the Messinian erosional surface at the margins and is evidence for a transition between a late lowstand stage and an early transgressive stage. These deposits belong to the Messinian upper megasequence (MUM). We interpret the transition between the two megasequences as the peak of the “salinity” crisis, the end of the relative sea level fall, and the maximum dispersal of sands into the deep Mediterranean basins

“…1A) opened as a consequence of the Corsica-Sardinia rifting that created the Algiers-Provence Basin in the Late Oligocene -Early Miocene (Guennoc et al, 1994;Mauffret et al, 2001). Thanks to long-term onshore and offshore investigations, this basin is one of the best known Neogene areas in the Mediterranean region (Depéret, 1885(Depéret, , 1890Bourcart, 1945;Gottis, 1958;Baudelot and Crouzel, 1974;Cravatte et al, 1974Cravatte et al, , 1984Michaux, 1976;Suc, 1976;Cravatte and Suc, 1981;Mein and Aymar, 1984;Clauzon and Cravatte, 1985;Clauzon, 1987Clauzon, , 1990Clauzon et al, 1987Clauzon et al, , 1990Aguilar et al, 1999;Guennoc et al, 2000;Duvail et al, 2005;Aunay et al, 2006;Suc and Fauquette, 2012).

“…Because the Roussillon Basin remained open during the Messinian drawdown, (1) the peripheral evaporites (1 st step of the Messinian Salinity Crisis: MSC; Clauzon et al, 1996) were not deposited here, and (2) the Messinian down-cutting of the preexisting fluvial network (2 nd step of the MSC; Clauzon et al, 1996) had a significant impact on the basin Duvail et al, 2005). As a result, the older Neogene deposits almost completely disappeared from the basin, which, in contrast, contains records of the marine reflooding and Zanclean variations in sea level (Fig.…”

The Roussillon Basin is a non-silled Miocene sedimentary basin filling a late Oligocene-early Miocene graben. The basin was intensively impacted by the 2 Messinian fluvial erosion, as evidenced in exposed sections, in seismic profiles and in deep boreholes drilled for hydrocarbon exploration. As the basin was open to the Mediterranean Sea, the huge drop in sea level at the peak of the Messinian Salinity Crisis is clearly recorded, along with the subsequent sudden marine reflooding and the resulting prograding sedimentary filling, particularly in Gilbert-type fan deltas. Here, the Messinian Erosional Surface (MES) is accurately mapped in a high-resolution document, which corrects the confusion resulting from the set of 1:50,000 scale regional maps. Aim of the 3D reconstruction of the MES is to modernize geological mapping, a crucial challenge for Mediterranean and peripheral areas. Thanks to a reliable chronostratigraphy provided by planktonic foraminifers, calcareous nannofossils, micro-and macro-mammal remains, paleomagnetism and a 10 Be cosmogenic nuclide-derived study, our reconstruction is one of the most comprehensive models of changes in sea level from 6 to 3 Ma. After the marine reflooding of the Mediterranean Basin at 5.46 Ma, the fluctuations in sea level recorded in the Roussillon Basin were forced by global changes. Following reflooding, the Prades large olistostrome collapsed prepared by the previous exhumation along the Canigou fault. The olistostrome is a good example of a local accident resulting from Messinian events. The exceptional changes in sea level at the peak of the Messinian Salinity Crisis deeply marked the Roussillon Basin, momentarily overprinting the Pyrenean orogenesis.
