“…Roveri et al & Giovanoli 1979): however, Messinian evaporites are absent in the Black Sea (Tari et al 2016). As occurs in modern times (Flood et al 2008), we argue that during Messinian cascading of hypersaline, dense waters, together with sediment gravity flows, could also have produced the Black Sea erosional surface but in a different way from the Mediterranean.…”

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.

“…Importantly, around the Black Sea no evidence is found for major river incisions during the MSC (Tari et al, 2016). Instead, the vast majority of the major erosional features present on seismic data are better interpreted as submarine canyon systems (Tari et al, 2016).…”

“…As a result, basin-scale interpretations following the early claims for deep desiccation of the Black Sea during the MSC (Hsü and Giovanoli, 1979), need to be revised. The interpretation of Suc et al (2015) of fluvial processes as the cause for major Messinian erosion in the SW Black Sea should also be reconsidered (Tari et al, 2016).…”

The Depositional Record

On the Island of Samos (East Aegean region, Greece), two sedimentary basins are filled by thick continental series dated to the Late Miocene to Early Pliocene. A multi‐disciplinary study has been performed including 1) the definition of 21 sedimentary facies, 2) a review of the biological components and 3) carbon, oxygen and strontium stable isotope analyses. The succession is characterised by various depositional settings and hydrochemical compositions. Five main stages of basin evolution have been identified: 1) The Late Serravalian is marked by the development of alluvial fans and fan delta; 2) during the Lower Tortonian, isolated shallow lakes with variable salinity, from fresh to brackish, developed under warm and relatively humid conditions; 3) the Middle to Upper Tortonian is marked by the development of a large and deep lake with saline and alkaline waters, under colder and drier conditions; 4) the Latest Tortonian to Messinian period is represented by an ephemeral alluvial system, developed under a dry climate; 5) during the Zanclean, a palustrine and paludal wetland system, dominated by tufa carbonates, developed under moderately humid conditions. This succession is of particular interest for the reconstruction of the palaeoenvironmental evolution of the transition zone between the Mediterranean domain, and the Paratethys and circum‐Paratethys areas. The geochemical data and the presence of flora (diatoms) and fauna (gastropods) of marine affinity suggest transient ingressions of marine‐related water or groundwater inflows as early as the Lower Tortonian. The Samos succession records the complex interaction between the regional geodynamics and climate. The extensional regime of the Eastern Aegean zone generates subsidence, interrupted in the mid‐Tortonian (9 Ma) by a brief compressive event and a major exposure of the basins. Furthermore, the Late Miocene progressive aridification, followed by a change to a more humid climate (Pliocene) is also a major driver of the sedimentation.
