“…2a). This confirms that fluids were able to flow across and out of the MES (Iadanza et al, 2015;Bertoni and Cartwright, 2015), as already suggested in previous works based only on seismic interpretations (CIESM, 2008;Lazar et al, 2012;Bertoni et al, 2013). The feeder channels crop out as discrete funnel-shaped fluid flow features filled with flow-mobilized pelites, crusts and nodules, similar to the fluid conduits that typify areas of focused fluid flow (Moss and Cartwright, 2010;Andresen, 2012).…”

“…For these reasons, besides their own potential as a petroleum system, the Messinian sediments also played a substantial role in the other Mediterranean petroleum systems, especially for the preMessinian ones (see Pawlewicz 2004;Belopolsky et al 2012;AlBelushi et al 2013;Bertoni & Cartwright 2015). We think that our chronostratigraphic framework and sequence stratigraphic approach may help in better identifying and characterizing these potentials in a coherent scenario.…”

“…These changes and their isostatic effects would cause overpressure and catastrophic fluid expulsions, even through the thick Messinian evaporitic unit that is usually considered an ideal seal (Bertoni & Cartwright 2015). Another aspect would be the degradation and/or remigration of pre-existing hydrocarbons (AlBelushi et al 2013;Iadanza et al 2015), with important implications for assessing the overall quality of the Mediterranean petroleum systems.…”

“…This phase of generalized exposure would have led to the formation of an erosional surface (the Messinian erosional surface -MES), which is one of the main stratigraphic features in both onshore and offshore records, and a key one for their correlation. The rapid water loading/unloading events would have caused significant pressure release and catastrophic fluid-expulsion phenomena (Ryan & Cita 1978;Bertoni et al 2013;Sacleux et al 2013;Bertoni & Cartwright 2015) that would have had a great impact on the pre-existing hydrocarbon migration and preservation.…”

The Messinian salinity crisis: open problems and possible implications for Mediterranean petroleum systems

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.

“…These morphostructures can be either explained as the results of vertical collapse associated with sink-hole like morphology, or explosive activity that partially empties the inner structural depression by ejection of volcanic material. Sinkholes are typical of karstic landscapes dominated by dissolution of carbonate rocks [36] or evaporites (usually at larger scale) [37], but very similar features may also develop in volcanic areas as a consequence of vertical collapse of volcaniclastic deposits due to archways backdown in lava tubes. BdP is located on the flanks of the Somma-Vesuvius complex and its formation is presumably related to volcanic processes.…”

Abstract:We report the geomorphological features of the continental shelf of the Gulf of Naples along the submarine slopes of the Somma-Vesuvius volcanic complex. This area is characterized by seafloor morphologies that are related to mantle degassing. Significant phenomena associated with this process occur. Doming of the seafloor has been detected in the area of Banco della Montagna, whereas a hole-like morphology has formed at Bocca dei Pescatori, likely as a result of a phreatic explosion. Outcropping or partially submerged volcanic bodies are also present as well as two main debris avalanche deposits arising from the main Somma-Vesuvius edifice. A large area characterized by an overall concave external profile and a global sediment wave morphology covers most of the southwestern area of the volcano.
