“…The Apulian carbonate platform is essentially a Mesozoic paleogeographic element, which, in large part, acted as a rigid block during the Alpine (Tertiary) orogenesis. Now, it is partly buried under the Apennine thrust sheets and partly constitutes the weakly deformed foreland of both the Apennine and Dinaric-Hellenic mountain chains (Channell et al, 1979;Mostrardini and Merlini, 1986;Underhill, 1989;Picha, 1996;Bosellini et al, 1999a, b;Bosellini, 2002;Karakitsios and Rigakis, 2007).…”

In western Greece, the Ionian and pre-Apulian zones represent, respectively, the basin and the transitional zone (slope) to the Apulian platform. The Apulian platform constitutes the weakly deformed foreland of the external Hellenides. The pre-Apulian zone appears in the Ionian Islands and the eastern Ionian Sea, whereas the Apulian platform is exclusively found in the Ionian Sea. The Ionian zone consists of Triassic evaporites, Jurassic–upper Eocene (mostly pelagic carbonates, minor cherts, and shales), overlain by the Oligocene flysch. Organic-rich source rocks occur within Triassic evaporites and Jurassic–Cretaceous pelagic argillaceous-siliceous rocks. The pre-Apulian zone consists of Triassic to Miocene deposits, mainly mixed neritic-pelagic carbonates. Hydrocarbon source rocks include pelagic and hemipelagic deposits rich in marine organic material, although terrigenous organic matter is also found in siliciclastic layers. Apulian platform source rocks are mainly the organic-rich shales within the Triassic Burano evaporites. Western Greece contains major petroleum systems, which extend into the Ionian Sea. Ionian, pre-Apulian, and Apulian petroleum systems contribute to the probable hydrocarbon accumulations within the big offshore (Ionian Sea) anticlines. Western Greece contains important oil and gas shale reservoirs with a potential of unconventional exploration. Promising areas for hydrocarbons need systematic and detailed three dimensional seismic data. Exploration for conventional petroleum reservoirs, through the interpretation of seismic profiles and the abundant surface geologic data, will provide the subsurface geometric characteristics of the unconventional reservoirs. Their exploitation should follow that of conventional hydrocarbons to benefit from the anticipated technological advances, eliminating environmental repercussions

“…Apulia was considered an isolated carbonate platform that developed away from emerged continents (D'Argenio et al, 1973) until the discovery of dinosaur footprints that suggested the presence of some continental bridges between Apulia and other coeval exposed regions in Late Jurassic to Early Cretaceous time (e.g., Bosellini, 2002). During the Mesozoic, shallow-water carbonate deposition was able to compensate for the regional subsidence, and led to the accumulation of a stratigraphic succession up to 6000 m thick (Ricchetti et al, 1998).…”

Did Adria rotate relative to Africa?

et al. 2014

Abstract. The first and foremost boundary condition for kinematic reconstructions of the Mediterranean region is the relative motion between Africa and Eurasia, constrained through reconstructions of the Atlantic Ocean. The Adria continental block is in a downgoing plate position relative to the strongly curved central Mediterranean subductionrelated orogens, and forms the foreland of the Apennines, Alps, Dinarides, and Albanides-Hellenides. It is connected to the African plate through the Ionian Basin, likely with Lower Mesozoic oceanic lithosphere. If the relative motion of Adria versus Africa is known, its position relative to Eurasia can be constrained through a plate circuit, thus allowing robust boundary conditions for the reconstruction of the complex kinematic history of the Mediterranean region. Based on kinematic reconstructions for the Neogene motion of Adria versus Africa, as interpreted from the Alps and from Ionian Basin and its surrounding areas, it has been suggested that Adria underwent counterclockwise (ccw) vertical axis rotations ranging from ∼ 0 to 20 • . Here, we provide six new paleomagnetic poles from Adria, derived from the Lower Cretaceous to Upper Miocene carbonatic units of the Apulian peninsula (southern Italy). These, in combination with published poles from the Po Plain (Italy), the Istrian peninsula (Croatia), and the Gargano promontory (Italy), document a post-Eocene 9.8 ± 9.5 • counterclockwise vertical axis rotation of Adria. Our results do not show evidence of significant Africa-Adria rotation between the Early Cretaceous and Eocene. Models based on reconstructions of the Alps, invoking 17 • ccw rotation, and based on the Ionian Basin, invoking 2 • ccw rotation, are both permitted within the documented rotation range, yet are mutually exclusive. This apparent enigma could possibly be solved only if one or more of the following conditions are satisfied: (i) Neogene shortening in the western Alps has been significantly underestimated (by as much as 150 km); (ii) Neogene extension in the Ionian Basin has been significantly underestimated (by as much as 420 km); and/or (iii) a major sinistral strike-slip zone has decoupled northern and southern Adria in Neogene time. Here we present five alternative reconstructions of Adria at 20 Ma, highlighting the kinematic uncertainties, and satisfying the inferred rotation pattern from this study and/or from previously proposed kinematic reconstructions.

“…From a review of the geophysical data of the Ionian Basin, CATALANO et al (2001) propose that the Ionian Sea is an abyssal plain of oceanic nature, bounded by two conjugate passive continental margins (Apulia and Malta escarpments), and that the disappearance of the original median ridge is due to thermal cooling and lateral burial by tertiary sediments. On the other side WEIGEL (1978), PAPAZACHOS and COMNINAKIS (1978), CLOETINGH et al (1980), FARRUGIA and PANZA (1981), CALCAGNILE et al (1982, ISMAIL-ZADEH et al (1998) andBOSELLINI (2002) propose that the Ionian Basin crust is of continental-intermediate type (thinned and stretched). From the reconstruction of the palaeotectonic and palaeogeographic history of the Eastern Mediterranean area (taking into account the presence of large dinosaurs on the Apulia carbonate platform), BOSELLINI (2002) supports the hypothesis that the Ionian Basin is mostly occupied by a stretched Vol.…”

A fairly detailed structural model of the lithosphere-asthenosphere system (thickness, S-and P-wave velocities of the crust and of the uppermost mantle layers) has been defined in the Calabrian Arc region (Southern Tyrrhenian Sea, Calabria and the northwestern part of the Ionian Sea) in Southern Italy using seismic data from literature as a priori constraints of the nonlinear inversion of surface-wave data.The main features identified by this study are: (1) A very shallow (less then 10 km deep) crust-mantle transition in the Southern Tyrrhenian Sea and a very low v s just below a very thin lid, in correspondence of the submarine volcanic bodies Magnaghi, Marsili and Vavilov, while the v s in the lid is quite high in the area that separates Marsili from Magnaghi-Vavilov; (2) a shallow and very low v s layer in the uppermost mantle in the areas of the Aeolian Islands, Vesuvius, Phlegraean Fields and Ischia, which represents their shallow-mantle magma source; (3) a thickened continental crust and lithospheric doubling in Calabria; (4) a crust about 25-km thick and a mantle velocity profile versus depth consistent with the presence of a continental rifted lithosphere, now thermally relaxed, in the investigated part of the Ionian Sea; (5) the subduction towards northwest of the Ionian lithosphere below the Southern Tyrrhenian Sea; (6) the subduction of the Adriatic/Ionian lithosphere underneath the Vesuvius and Phlegraean Fields.
