“…The latter are well documented by the 87 Sr/ 86 Sr Mediterranean curve (Fig. 1), which shows a significant, stepwise detachment from the global ocean curve during the MSC, suggesting a progressive hydrological isolation and/or an increase in the relative proportion of continental waters over that of the ocean ones (see Flecker et al 2002;Roveri et al 2014b). Each one of the three stages of the crisis shows a distinct range of 87 Sr/ 86 Sr values: > 0.708900 for stage 1; between 0.708800 and 0.708900 for stage 2; and < 0.708800 for stage 3.…”

A general agreement on what actually happened during the Messinian salinity crisis (MSC) has been reached in the minds of most geologists but, in the deepest settings of the Mediterranean Basin, the picture is still far from being finalized and several different scenarios for the crisis have been proposed, with different significant implications for hydrocarbon exploration. The currently accepted MSC paradigm of the 'shallow-water deep-basin' model, which implies high-amplitude sea-level oscillations (> 1500 m) of the Mediterranean up to its desiccation, is usually considered as fact. As a consequence, it is on this model that the implications of the MSC events on the Mediterranean petroleum systems are commonly based.In fact, an alternative, deep-water, non-desiccated scenario of the MSC is possible: it (i) implies the permanence of a large water body in the Mediterranean throughout the entire Messinian salinity crisis, but with strongly reduced Atlantic connections; and (ii) envisages a genetic link between Messinian erosion of the Mediterranean margins and deep brine development.In this work, we focus on the strong implications of an assessment of the petroleum systems of the Mediterranean and adjoining areas (e.g. the Black Sea Basin) that can be based on such a non-desiccated MSC scenario. In particular, the near-full basin model delivers a more realistic definition of Messinian source-rock generation and distribution, as well as of the magnitude of water-unloading processes and their effects on hydrocarbon accumulation.

“…In the TPB, the Messinian sequence starts with the pre-evaporitic deepwater marine marls of the Marne di Sant'Agata Fossili Formation. The latter are followed by alternated gypsum and clay beds of the Primary Lower Gypsum, which deposited in the evaporitic stage between 5.96 and 5.60 Ma (CIESM, 2008;Roveri et al, 2014). The Valle Versa Chaotic Complex (5.60-5.55 Ma) unconformably overlies the Primary Lower Gypsum.…”

“…The Messinian succession is capped by the Zanclean marine clays of the Argille Azzurre Formation . Therefore, the age of the fossiliferous layers is constrained between 5.41 and 5.33 Ma, within stage 3.2 of the MSC (sensu Roveri et al, 2014). However, the whole fossiliferous succession was likely deposited in a much shorter time lapse, based on the taphonomic features of the fauna as well as on the consistently stable taxonomical content of the fossiliferous layers.…”

Sulfate deposits of the Loei-Wang Saphung (LWS) area, northeastern Thailand, intercalated with carbonate and silicic clastic rock were analyzed for S, O, C, and Sr to determine the depositional environment, as well as the age of formation. Sulfate samples yielded average values of δ 34 S of 14.6‰, while the 87 Sr/ 86 Sr ratio of gypsum was 0.708282 and that of anhydrite was 0.708288. The carbonate layers yielded average δ 18 O PDB , and δ 13 C values of −12.5‰ and −0.1‰, respectively. Our results revealed that the LWS evaporite deposits were originally formed from seawater, and the relatively negative value of δ 18 O was a result of meteoric alteration during subaerial exposure of the sections. Comparing these isotopic values with the nearby Nakon Sawan sulfate deposits, the Sr isotopes showed slightly higher values with very mild variations. These isotopic values suggest that the LWS deposits were not affected by subsequent hydrothermal alteration by younger igneous dikes in this area. Therefore, some of these isotope signatures are considered to be primary features of the deposit, despite the fact that the deposit underwent anchizone to epizone metamorphism. The S and Sr isotope values support the depositional age of the LWS sulfate deposit in the Middle to Late Carboniferous.
