NEW OIL SOURCE ROCKS CUT IN GREEK IONIAN BASIN (1996)
The Ionian zone of Northwest Greece (Epirus region) constitutes part of the most external zones of the Hellenides (Paxos zone, Ionian zone), Gavrovo Tripolitza zone). The rocks of the Ionian zone range from Triassic evaporites and associated breccias through a varied series of Jurassic through Upper Eocene carbonates and lesser cherts and shales followed by Oligocene flysch. The surface occurrences of petroleum in the Ionian zone are mainly attributed to Toarcian Lower Posidonia beds source rocks and lesser to late Callovian Tithonian upper Possidonia beds and to the Albian Cenomanian Upper Siliceous zone of Vigla shales of the Vigla Limestones.
