“…Furthermore, the absence of subevaporite units from outcrops in western Greece, the great thickness of the evaporites (>3 km [2 mi] in boreholes in the Ionian zone; IGRS-IFP, 1966;BP, 1971), and the probable incorporation of Permian basement into the thin-skinned orogenic wedge east of the Pindos thrust (Smith and Moores, 1974) all support the idea that the evaporites form a moderate to major décollement level throughout the external Hellenides, instead of a widespread diapirism (Underhill, 1988;Karakitsios, 1992Karakitsios, , 1995Kamberis et al, 1996;Karakitsios and Rigakis, 2007). Thus, the function of the evaporites is similar to that which is well known in thin-skinned thrust belts in western Europe (Rigassi, 1977;Laubscher, 1978;Williams, 1985;Allen et al, 1986;Ricci Lucchi, 1986).…”

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

“…Foreland basins are sedimentary basins that lie between a mountain front and the adjacent craton in 222 compressional settings (Allen et al, 1986;Covey, 1986;DeCelles, 2012). We delineated geomorphic 223 elements in portions of three foreland basins-the Himalayan foreland basin in India (Fig.4), the Chaco 224…”

“…The abovementioned angular unconformity can be related to the first episode of subaerial exposure and erosion of some uplifted sectors of the SFTB [1,3], thus marking the time since the Sicilian orogen become the main source of sediments for the inner sectors of the foreland basin (continental wedge phase [50] or molasse stage [51,52]. This unconformity has been recognized not only in the stratigraphy of Sicily, but even in the northern and southern Apennines [53,54] indicating a Mediterranean-scale event.…”

Detailed field sedimentological and facies analyses have been performed in the Terravecchia Formation cropping out in NW Sicily, in order to differentiate and describe, for the first time, wave-and river-dominated shallow-marine (deltaic) siliciclastic successions. The latter were deposited filling syntectonic basins, developed between the late Tortonian and early Messinian time, within the wedge-top depozone of the Sicilian Foreland Basin System. It has been observed that river-dominated successions, recording the deposition of small fan-deltas are characterized by fining-to coarsening upward, transgressive-regressive sequences which were mostly deposited filling relatively narrow and often oversupplied basins. These basins were probably located in a proximal sector of the wedge-top depozone, closer to emergent sectors of the chain and probably sheltered from the main marine areas. Wavedominated successions, on the other hand, are characterized by upward fining, mostly transgressive sequences which were deposited filling wider basins open to major marine regions and located in a more distal position of the wedge-top depozone. The documented partitioning between river-and wave-dominated successions, as a function of the position of the sedimentary basin within the wedge-top depozone, is coherent with data from analyses of the deformational patterns of the Terravecchia Formation in this study area. Furthermore, the data here presented could be considered as a preliminary database for future characterization and analysis of siliciclastic reservoirs from Sicilian outcrop analogues.
