“…The Ionian zone consists of sedimentary rocks ranging from Triassic evaporites to Jurassic-upper Eocene carbonates and minor cherts and shales, overlain by Oligocene flysch. Organic-rich intervals occur within Triassic evaporites and Jurassic-Cretaceous pelagic argillaceous sediments (Karakitsios, 1995;Rigakis, 1996, 2007;Rigakis and Karakitsios, 1998). The Gavrovo zone was a shallowwater platform from the Triassic to the late Eocene, from which no organic matter-rich deposits have so far been found .…”

“…The important function of Triassic formations, which are commonly associated with evaporites, in the peri-Adriatic domain as hydrocarbon source rocks (Mattavelli et al, 1993), has a particular significance in the context of the Ionian zone (Epirus region, northwestern Greece). In fact, organic-rich shale fragments have been observed in the Triassic breccias that constitute the surface expression of the subsurface Ionian evaporites (Rigakis and Karakitsios, 1998;Karakitsios and Rigakis, 2007). The Triassic breccias and associated gypsum bodies, underlining the Ionian tectonic zones, constitute diapiric injections of subsurface evaporites.…”

“…Systematic research since 1960 (IGRS-IFP, 1966;BP, 1971;Monopolis, 1977;Chiotis, 1983;C. Nikolaou, 1986, personal communication;Palakas et al, 1986;Karakitsios, 1992Karakitsios, , 1995Roussos and Marnelis, 1995;Karakitsios and Rigakis, 1996;Rigakis and Karakitsios, 1998;Karakitsios et al, 2001; Zelilidis et al, 2003;Rigakis et al, 2004;Karakitsios and Rigakis, 2007;Marnelis et al, 2007) has proven now that western Greece is characterized by rich source rocks of significant thickness, located in the Ionian and pre-Apulian (Paxos) zones. Limited early exploration focused on the abundant oil shows (Monopolis, 1977), and more recent exploration did not give encouraging results (Xenopoulos, 2000), although both Albania and Italy host substantial oil and gas fields (Mattavelli and Novelli, 1990;Van Greet et al, 2002;Mavromatidis et al, 2004;Roure et al, 2004;Graham Wall et al, 2006;Vilasi et al, 2009;Maravelis et al, 2012).…”

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

“…The early Toarcian (ca 183 Ma) coincides with high palaeotemperatures (Bailey et al 2003), regional anoxia to euxinia, marine transgression, mass extinction (Little and Benton 1995) and high rates of organic-carbon burial, attributed to a so-called Oceanic Anoxic Event (Schlanger and Jenkyns 1976;Jenkyns 1988;Karakitsios 1995;Rigakis and Karakitsios 1998;Jenkyns et al 2001). The geochemical characteristics of the early Toarcian OAE (or T-OAE) are a relative maximum in total organic carbon (TOC) and a broad, locally subdued positive carbon-isotope excursion punctuated by an abrupt negative excursion, recorded in marine organic matter, marine pelagic and shallow-water carbonate and terrestrial organic material Clayton, 1986, 1997; Jenkyns et al 2001;Jenkyns, 2003Jenkyns, , 2010Kemp et al 2005;Hesselbo et al 2007;Woodfine et al, 2008).…”

“…This palaeogeographic configuration persisted with minor off-and onlap movements along the basin margin until the Late Eocene, when orogenic movements and flysch sedimentation began. The particular geometry of the restricted sub-basins that were formed during the syn-rift period of the Ionian Zone may have favored increased organic-matter burial during the Toarcian-Tithonian interval (Baudin et al 1990;Karakitsios, 1995;Rigakis and Karakitsios, 1998;Karakitsios and Rigakis, 2007). Toarcian black shales in the Ionian Zone were described first by Renz (1910), who compared them with the Posidonienschiefer of Germany, and sedimentological details were given by Walzebuck (1982).…”
