“…The data converge to those of the organic geochemical study (Rock-Eval pyrolysis and GC-MS) (Guido et al 2007) and permit to consider the FT-IR a reliable approach in the characterization of the organic matter preserved in carbonates sediments.…”

“…These filaments have been petrographically described earlier and were interpreted either as remains of algal mats (Vai & Ricci Lucchi 1977) or cyanobacteria (Rouchy & Monty 1981). Similar filamentous textures were identified in the Messinian Calcare di Base Formation in northern Calabria, which were interpreted as faecal pellets of brine shrimps (Guido et al 2007). …”

“…To perform fast analyses on organic matter, able to recognize not only its crude presence but also its geochemical composition and thermal maturity, we tested the Fourier Transformed-InfraRed (FT-IR) spectroscopy on samples already studied and characterized through molecular fossils and other organic markers (Guido et al 2007). The Authors demonstrated that the Calcare di Base (CdB), cropping out in the Rossano Basin (Northern Calabria, Italy), was deposited via heterotrophic bacterial activity in a marine setting.…”

“…The source-rock potential of MSC deposits has been documented in several areas: the Chelif Basin (northern Algeria: Arab et al 2015), the Prinos-Kavala Basin (northern Aegean: Kiomourtzi et al 2008), the island of Zakynthos and the Hellenic Trench (Greece: Maravelis et al 2013Maravelis et al , 2015, the Ionian Basin (Deroo et al 1978), the southern Apennines (Guido et al 2007), and the northern Apennines (Manzi et al 2007). However, a full knowledge of the Messinian source rocks is lacking, mainly due to the difficulty in organizing the available scattered data and observations into a comprehensive and detailed stratigraphic framework.…”

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.

“…As it can be clearly seen the transmission spectra before 276 thermal processing (solid lines in Figs. 5a and 5b) exhibit the typical absorption bands of aragonite 277 at 1476 cm -1 (6.8 µm), 1083 cm -1 (9.2 µm), 856 cm -1 (11.7 µm) and a double peak around 700 cm It is worthwhile to note the relative simplicity of our method compared to the sophisticated 324 geobiological investigations already applied and discussed by Guido et al (2007). On the other 325 hand, we acknowledge a possible drawback of our method due to the relatively small number of 326 samples used to validate it.…”
