Post- Alpine Late Pliocene – Middle Pleistocene Uplifted Marine Sequences in Zakynthos Island

Abstract

Post-orogenic marine sequences crop out in two areas of Zakynthos Island: a) In Gerakas peninsula at the southeastern edge of the island and b) Along the coastal zone of central northern

Contrasting Styles of Salt‐Tectonic Processes in the Ionian Zone (Greece and Albania): Integrating Surface Geology, Subsurface Data, and Experimental Models

“…The Middle Jurassic succession (Toarcian to Kimmeridgian) shows important variations in thickness (from few meters up to 200-300 m) and sedimentary facies (Aubouin, 1958;Bernoulli & Renz, 1970;Bourli et al, 2019;IFP, 1966;Karakitsios, 1995;Nikolaou, 1988;Renz, 1955;Savoyat, 1977;Vakalas et al, 2023). The following sequences can be distinguished: "ammonitico rosso" marly limestones and the marly limestones of Other sources of information used to prepare this column are as follows: for the general chronostratigraphy of the Upper Triassic-to-Eocene carbonate section (Bega & Soto, 2017;Bourli et al, 2019;BP, 1971;IFP, 1966;Kamberis et al, 2022;Karakitsios, 2013;Meço et al, 2000;Papanikolaou, 2021;Rigakis & Karakitsios, 1998;Robertson & Shallo, 2000;Zelilidis et al, 2003Zelilidis et al, , 2015Zoumpoulis et al, 2022); and for the lithostratigraphy of the Oligocene and Miocene "flysches" and the most recent sedimentary sequences (Avramidis et al, 2002;Bellas, 1997;Bellas et al, 1995;Botziolis et al, 2021;Gjika et al, 2001;Kostopoulou et al, 2022;Makrodimitras et al, 2010;Maravelis et al, 2014;Papanikolaou et al, 2010;Papanikolaou & Lekkas, 2008;Sotiropoulos et al, 2008;Triantaphyllou, 2013). The positions of the different elements of the petroleum system, like possible source rocks (with TOC contents in wt.%) and reservoir and seal lithologies (with average porosity values in %) are from this study, averaging also determinations from previous works…”

“…Zakynthos, also called Zante, is located in western Greece and is the third largest of the Ionian Islands, with an area of about 406 km 2 (Figure 1a,b). Zakynthos Island is at the front of the present-day Hellenic arc and trench system that formed along the convergent zone between the subducted African plate and the thrusting Eurasian plate (e.g., [46][47][48]). Lying close to the western edge of a tectonic plate, Zakynthos Island is exposed to seismic activity (e.g., [49][50][51]) that is reflected in the landscape via a pronounced relief.…”

Exhumed hydrocarbon-seep authigenic carbonates from Zakynthos Island (Greece): Concretions not archaeological remains

“…The local bedrock is Plio-Pleistocene marl, claystone and sandstone (Papanikolaou et al, 2010) resting unconformably on the Paxos Unit, the tectonic foreland of the Hellenic Orogen, here comprising Mesozoic to Paleogene aged limestones, dolostones, cherts, porcelanites and evaporites (Dermitzakis 1978, Perry and Temple 1980, Brooks and Ferentinos 1984, Nikolaou 1986, Stamatakis et al, 1988, Triantaphyllou et al, 1997, Papanikolaou et al, 2010, Kokkalas et al, 2012.
