“…Such sediments have been reported as possible indicators of increased carbonate saturation during some major mass extinctions, for example, in the Late Ordovician (Sheehan and Harris, 2004), the FrasnianeFamennian transition (Whalen et al, 2002), and especially the end-Permian (Baud et al, 2005;Hips and Haas, 2006;Payne et al, 2006;Kershaw et al, 2012;Woods, 2014). Similar changes in the carbonate sedimentation were also related to minor extinction global events during the Silurian (Calner, 2005) and early Toarcian (Trecalli et al, 2012) as well as local Messinian Salinity Crisis (Bourillot et al, 2010).…”

“…8D and 9) showing an erosional contact between the pre-and post-MSC deposits (Clauzon et al, submitted for publication). On the other hand, in the center of the basin, the tabular geometry of the Messinian gypsum layers and overlying Pliocene bottomset beds has usually been ascribed to a continuous stratigraphic transition Krijgsman et al, 2001;Bourillot et al, 2010). The 3D modelling of the Messinian unconformity confirms the relatively flat geometry of that surface (see North and East of Sorbas city; Fig.…”

“…Many scenarios for the Neogene evolution of the whole Alboran region were based upon the stratigraphy and structure of the Sorbas Basin. However, several conflicting stratigraphic models of the basin have been proposed so far (Dronkert, 1976;Pagnier, 1976;Ott d'Estevou et al, 1990;Riding et al, 1991;Rouchy and Saint-Martin, 1992;Dabrio and Polo, 1995;Clauzon et al, 1996;Conesa et al, 1999;Fortuin et al, 2000;Krijgsman et al, 2001;Bourillot et al, 2009;Roveri et al, 2009;Bourillot et al, 2010;Clauzon et al, submitted for publication) and while geometries of the lower Messinian deposits have been well-established before (Weijermars et al, 1985;Ott d'Estevou and Montenat, 1990), the spatial relationships between the Messinian gypsum and post-MSC deposits are much less constrained. Discrepancies concern the presence or absence of the Messinian Erosional Surface (MES) in the Sorbas Basin if any and its stratigraphic location.…”

a b s t r a c tThe scenario of the Messinian Salinity Crisis (MSC) remains one of the most debated topics in the Mediterranean realm and especially in the Sorbas Basin, which is one of the type-localities of MSCrelated deposits. After a recently improved chronostratigraphic framework of the Miocene and Pliocene deposits of the basin, this work is an attempt to image the morphology of the Messinian Erosional Surface (MES) at depth. We built a basin-scale 3D-model of the Miocene and Pliocene series that confirms the erosional character of the Messinian/Pliocene boundary, solving a long-standing and debated question. We tentatively also suggest that the fluvial system developed during the peak of the MSC was exiting the basin toward the south. This new geometrical model, showing a robust internal consistency, can be used as a basis for interpreting the Messinian Salinity Crisis in other sedimentary basins around the Mediterranean Sea. The return of marine conditions in the Early Pliocene on an erosional surface interferes with the continuous formation of the Sorbas Basin asymmetrical syncline, subsidence of the hinge, uplift of the limbs and gravitational sliding. The irregular shape of the MES is superimposed in the southern part of the basin by small-scale box-type folds with two oblique NNEeSSW and WNWeESE fold axes directions. The architecture of these folds suggests gravitational sliding of post-evaporitic marine sediments during the progressive deformation of the basin during the Zanclean.

“…Surface 3 represents 233-533 thousand years of subaerial exposure (Table 1). Age estimates for possibly equivalent strata in the Mediterranean basin suggest between 100 and 400 thousand years for all of TCC deposition (Franseen et al, 1998;Bourillot et al, 2010). The range of values also incorporates uncertainties discussed by Cande and Kent (1995).…”

This transition from evaporite to Lago-Mare facies implies an increase in wet conditions and a decrease in aridity.…”

We isolated the impact of climate, duration, and mineralogy on porosity enhancement and cementation associated with seven surfaces of subaerial exposure in Miocene carbonate strata of southeast Spain. We integrated new and published petrographic and geochemical studies on the same strata to quantify the approximate impact of each event of subaerial exposure. The results quantified that only minor dissolution and/or cementation occurred when subaerial exposure was short-lived (<533 thousand years) and in an arid climate, or when carbonate sediments were composed primarily of calcite. For such exposure surfaces, alteration was confined to the uppermost 0.5-2 m with 2%-5% porosity from dissolution and 3% cementation. After deposition of the last Miocene carbonate sequence, dolomitization and dissolution occurred during the initial stages of sea-level fall, associated with mixing during influx of meteoric water. This resulted in dissolution to create 10%-20% porosity over 83% of the platform system, and this indicated that even incipient subaerial exposure can lead to major porosity enhancement during times of high freshwater recharge and hydrogeology that promotes mixing. During a long-lived period of subaerial exposure (greater than 5.3 million years) associated with wet climate, major amounts of cementation reduced porosity in the phreatic zone and some porosity was enhanced in the vadose zone. This included 25% freshwater calcite cement affecting 53% of the platform. Dissolution during and after calcite cementation was approximately 8% throughout the platform. These observations predict that duration and climate combine to have the most significant impacts on porosity associated with subaerial exposure.
